{{art-wikipedia|Leffen}}

'''Leffen''' is a professional smasher from Stockholm, [[Sweden]]. He is considered to be one of the greatest ''[[Super Smash Bros. Melee]]'' players of all time and the second-greatest ''Melee'' player from Europe, after {{Sm|Armada}}. He intially began as a {{SSBM|Falco}} main,<!--Leffen has stated multiple times that he has never mained Yoshi--> but later switched to {{SSBM|Fox}}, and is now known as one of the greatest Fox players of all time. He is also a notable {{SSBM|Sheik}} player, using Sheik as a counterpick to {{SSBM|Marth}}. He is the first of only two players in competitive ''Melee'' history to have taken a set off of each of the "[[Five Gods]]" (the other being {{Sm|Plup}}), and has often been called a god himself since his ascent in 2014. Leffen was formerly ranked 1st on the [[Swedish Power Rankings|Swedish ''Melee'' Power Rankings]]. He is also an honorable mention on the [[SSBMRank 2023]] and [[EURank 2023]].

Although Leffen did not play ''Brawl'' competitively and only went to a few ''Smash 4'' tournaments, he was active in ''[[Ultimate]]'' for the game's first year, maining {{SSBU|Pokémon Trainer}} and briefly touching {{SSBU|Pichu}} and {{SSBU|Roy}}. During this period, he was considered one of the best Pokémon Trainer players in the world along with {{Sm|Tweek}}, {{Sm|moxi}}, and {{Sm|Ned}}. Leffen has defeated players such as Tweek, {{Sm|Salem}}, {{Sm|WaDi}}, {{Sm|Puppeh}}, {{Sm|Mr.R}}, {{Sm|Maister}}, {{Sm|ZD}}, and {{Sm|8BitMan}}. He was listed as an Honorable Mention on both the [[Swedish Power Rankings|Swedish ''Ultimate'' Power Rankings]] and the [[European Smash Rankings]], and was formerly ranked in the Area 51 position on the [[Fall 2019 PGRU]].

Leffen's competitive ''Smash'' career has been mired by several controversies. Noted for his abrasive personality and penchant for confrontational behavior, he is considered one of the more polarizing figures across the community.<ref>[https://meleestats.co/ultimatessbmrank-no-8-leffen/]</ref> Over the years, he has been accused of aggressive and toxic behavior, bullying, and poor sportsmanship.<ref>[https://www.invenglobal.com/articles/16883/leffen-under-fire-for-past-toxic-behavior-towards-mew2king-kensou-and-smash-community]</ref> Early into his career, he was banned for a year by Swedish community representatives and tournament organizers from all Swedish tournaments for poor behavior during tournaments, with supporting evidence for his ban compiled into a zip file titled "Evidence.zip" in February 2013.<ref>[https://smashboards.com/threads/leffen-is-banned.333990/ Original ban post]</ref> This series of events would become the basis for his feud with {{Sm|Hax$}} after June 2021, following Hax's upload of several videos with accusations of additional misconduct.

==Tournament history==
===2010-2013: Early career===
Leffen's introduction to ''Smash'' was through ''[[Brawl]]'', which he played online in 2009.

In 2010, he started attending tournaments for ''[[Melee]]''. He mained Falco and also trained a Yoshi secondary, which he used to great success at Stockholm locals and at Danish events.

Throughout the course of 2012, Leffen established himself as Europe's second-strongest player behind {{Sm|Armada}}, with key results at {{Trn|Smashers' Reunion: Melee Grande}} and at {{Trn|hf.lan 4}}. He sparred often with Armada, making headway but never taking a set. He came closest at {{Trn|Beauty 6}} in January 2013, where he was leading winners' finals 3-2 (in a best-of-7) and brought the sixth game to last stock before Armada clutched out the victory, going on to win the set 4-3.

Leffen also began traveling to North American supermajors during this time, and was noted as one of Armada's frequent travel companions from Europe. He displayed many respectable performances vs. the world's best players, but ultimately failed to make any top eight placings in North America from 2011 to 2013. {{Trn|GENESIS 2}} was his first tournament in the United States, where he placed 17th, defeating {{Sm|SFAT}} in pools, but losing to SFAT and {{Sm|S2J}} in bracket. At {{Trn|Apex 2012}}, his first serious event as a Fox main, Leffen placed 33rd, and lost a last-hit set to {{Sm|Mew2King}} in winners. At {{Trn|Apex 2013}}, Leffen defeated {{Sm|MacD}} and {{Sm|Cactuar}} in winners to meet {{Sm|Hungrybox}}. He made a splash by bringing Hungrybox to last hit but lost this set as well; this close loss would go on to inspire a [[Salty Suite]] rematch the following year. In losers, Leffen lost another last-hit set to {{Sm|JAVI}}, placing 17th.

In February 2013, a group of prominent TOs and community members (led by Armada) announced that [[#Ban from European tournaments & Evidence.zip|Leffen was banned]] was from many European tournaments due to his conduct. As a result, he only attended three tournaments for the rest of year. His most significant result was at {{Trn|EVO 2013}}, where he defeated {{Sm|PewPewU}} before losing to Hungrybox and {{Sm|Shroomed}} in losers to place 9th, his strongest placing at an American tournament to date. He and {{Sm|Ice}} scored an upset victory in doubles against eventual victors {{Sm|Mew2King}} and {{Sm|Hungrybox}}; the European team went on to place 5th.

Leffen also attended a [[Tristate Area|New York City]] local in September called CFST: Warzone 2, where he suffered unusual losses to {{Sm|MattDotZeb}} and {{Sm|G$}}, perhaps due to lack of practice. He finished out the year at {{Trn|hf.lan 6}} where he placed second, defeating {{Sm|Baxon}} and {{Sm|Salepate}} convincingly before losing two close sets to {{Sm|Ice}}. Given his powerful play despite his scarce results, Leffen was ranked 14th on the [[2013 SSBMRank]].

Leffen's ban ended in early 2014, allowing him to compete in Europe again.

===2014: Emergence as a top six player===
2014 marked Leffen's emergence into the highest level of competitive ''Melee'', establishing himself as one of the six best players in the world. He had a breakout performance at {{Trn|Apex 2014}}, where he earned his first set victory over one of the [[Five Gods]], defeating {{Sm|Hungrybox}} 2-1 in winners' quarters (despite losing 1-3 in a Salty Suite the previous day). He then lost to {{Sm|Mew2King}} 1-3 in winners' semis; in losers' he beat {{Sm|Colbol}} 2-0 and then had a close and intense set with {{Sm|Mang0}} in losers' semis, but ultimately lost 2-3, getting 4-stocked to close out the set. This 4th place showing immediately confirmed Leffen as a player to watch for the rest of the year and presaged his ascent as a top player.

Back in Europe, Leffen won his first European national and defeated his second God at {{Trn|B.E.A.S.T 4}}, winning two sets against Armada from losers, 3-0 and 3-1 respectively. Leffen then won {{Trn|Republic of Fighters 3}}, qualifying for the {{Trn|MLG Anaheim 2014}} championship bracket. After losing to Armada 0-3 in winners' finals, he returned to grand finals and defeated him 6-0 across two sets.

Leffen competed in two American supermajors in the summer of 2014: MLG Anaheim 2014 and {{Trn|EVO 2014}}. In his pool at MLG Anaheim 2014, Leffen earned his third God victory by defeating PPMD 3-2. He also defeated {{Sm|Axe}}, Colbol 3-1, {{Sm|s0ft}}, and {{Sm|Remen}}, but lost to Mew2King and {{Sm|Hax}}. Seeded in losers' for the championship bracket, he defeated both {{Sm|Westballz}} and Hax, before losing to PPMD 1-3 in losers' quarters, placing 5th overall. At EVO 2014, Leffen lost to Mew2King 0-2 in winners' quarters. In the losers' bracket, he was eliminated by {{Sm|Silent Wolf}} 1-2, finishing off at an underwhelming 9th place overall.

Leffen's last big event of the year was {{Trn|The Big House 4}}, where he defeated Hungrybox 3-2 in winners' quarters and Armada 3-2 in winners' semis; this marked the first time Leffen made winners' finals at an American major. However, he lost 0-3 to Mew2King in winners' finals and 1-3 to Mang0 in losers' finals, with a 4-stock by Mang0 to close out the set, finishing 3rd, his best major placement so far.

Leffen ended the year ranked 6th on the [[SSBMRank 2014]], only behind the Five Gods. Many players now viewed Leffen in the same tier as the Gods (as part of a new "big six,"), as he was the first non-God who had proven the ability to consistently beat several of them in tournament, and rarely losing sets to non-God players. He was popularly nicknamed "The Godslayer" as a result.

===2015: Rise to the top===
2015 marked Leffen's final push to the very top of competitive ''Melee'', defeating all five Gods and competing for the title of best player in the world. He started the year at {{Trn|B.E.A.S.T 5}}, where he defeated Armada 3-1 in winners' semis, earned his first victory over Mang0 3-2 in winners' finals, and faced Armada again in grand finals. Despite a closely fought set from both players (with Armada notably 4-stocking Leffen in game 4), Leffen managed to win grand finals 3-2; Leffen had now defeated four of the Five Gods, and became the first non-God to win a major with at least two of the Gods present since the start of the Five Gods era. Mew2King was now the only God he had yet to beat.

{{Trn|Apex 2015}} was a highly anticipated tournament for Leffen. He first fought [[Leffen vs. Chillin (Apex 2015)|a Salty Suite exhibition match]] vs. {{Sm|Chillin}}; Leffen easily won 5-0, and as punishment for losing, Chillin was unable to use the default {{SSBM|Fox}} color in tournament ever again. Following the match, Mang0 went on stage and challenged Leffen to place $1000 on their match if they played each other in bracket, which Leffen accepted.

In the main bracket, Leffen easily made it to winners' quarterfinals to face Mew2King, his last undefeated God. In a momentous 2-1 victory, including a dominant 3-stock in game 3, Leffen defeated Mew2King, becoming the first player to take a tournament set from all of the Five Gods of ''Melee''. He then went on to defeat Mang0 3-1, winning the set and earning an additional $1000. Looking poised to take the tournament, Leffen ultimately fell to PPMD 2-3 in winners' finals and Armada 1-3 in losers' finals, earning 3rd place. Having defeated all Five Gods in tournament, and having outplaced three of them, Leffen cemented his title as the "Godslayer" of ''Melee''. (While Leffen was considered at the same level as the Gods, the ''Melee'' community has reserved "God" as a historical title to mark an era of the game's competitive history.)
Soon after, Leffen was signed by [[Team SoloMid]], one of the largest and most famous eSports organizations.<ref>{{cite web|url=https://web.archive.org/web/20230808021706/https://www.esportsheaven.com/news/leffen-signs-with-tsm-could-branch-out-into-other-fgc-titles/|title=Leffen signs for Team SoloMid}}</ref>

In the spring of 2015, Leffen placed 3rd at {{Trn|I'm Not Yelling!}}, 5th at {{Trn|Sandstorm}}, and 9th at {{Trn|Press Start}} (where he was upset 2-3 by {{Sm|SFAT}} in winners' quarters and lost 0-3 to Mang0 in losers' bracket); this was now considered a relative underperformance for Leffen.

Leffen's dominance continued to grow throughout the summer of 2015, and following a series of first place finishes, he developed a claim as the best player in the world. At {{Trn|CEO 2015}}, Leffen won his first American major, defeating Armada twice in winners' finals 3-0 and grand finals 3-1. He then placed first at {{Trn|FC Smash 15XR: Return}}, where he beat Hungrybox 3-1 in winners' semis and Armada 3-1 in winners' finals, including a 4-stock in game 1 on {{SSBM|Final Destination}}. In grand finals, he met Hungrybox once again and beat him 3-1. Leffen earned another major victory at {{Trn|WTFox}}, including an impressive 3-0 victory over Mang0's Falco in grand finals, marking three consecutive first place finishes in singles.

Following his three major wins, Leffen was seen as the favorite to win {{Trn|EVO 2015}}, the biggest event of the summer. However, he failed to repeat this success at EVO, as he was sent into losers by Hungrybox and then upset by Plup's Samus for 5th place.

At {{Trn|Super Smash Con 2015}}, Leffen bounced back and took first place once again in singles, beating Mew2King 6-1 collectively in winners' finals and grand finals. Mew2King answered back in their next meeting at {{Trn|PAX Prime 2015}}, where Mew2King famously took the tournament with a collective 6-0 victory over Leffen.

Due to his performances, Leffen was ranked 2nd on the [[Summer 2015 SSBMRank]] (only behind Armada); by now, Leffen had firmly established himself as a clear tournament favorite.

Leffen entered more American events in fall 2015. At {{Trn|Paragon Los Angeles 2015}} he was sent to losers by Mew2King, and eliminated by Hungrybox, ending at 5th place. At {{Trn|HTC Throwdown}}, Leffen made it to grand finals from the winners' side, where he defeated Hungrybox 3-0.

===2015-2016: Visa issues===
Leffen's reign of dominance was cut short, however. While traveling to {{Trn|The Big House 5}}, he was denied entry into the United States and deported due to his lack of a workers' visa (as required due to his sponsorship by Team SoloMid). Leffen was unable to enter the Big House 5, and his visa issues continued to affect him for over a year, preventing him from entering many large tournaments, including {{Trn|Smash Summit}}, {{Trn|GENESIS 3}}, {{Trn|Battle of the Five Gods}}, and {{Trn|Smash Summit 2}}. Furthermore, he was denied a worker's visa from the United States, primarily for reasons that questioned ''Melee''{{'}}s legitimacy as a sport. [https://www.youtube.com/watch?v=MdVejIOYp-M The video showing the rejection letter] started a movement to reverse the decision, including a petition on the White House's official website.<ref>{{cite web|url=https://web.archive.org/web/20230808024148/https://esport.aftonbladet.se/ssbm/svensken-nekad-intrade-till-usa-missar-turnering/|title=Leffen is denied entry to The Big House 5 (in Swedish)}}</ref><ref>{{cite web|url=https://web.archive.org/web/20230808023716/https://dotesports.com/general/news/white-house-free-leffen-petition-response-3523|title=White House responds to ‘Free Leffen’ petition, won’t make any changes to esports visa policies}}</ref> Eventually, Leffen was temporarily allowed into the United States up until and throughout July 2016, tentatively letting him attend {{Trn|EVO 2016}}.<ref>{{cite web|url=http://tsm.gg/index.php/news/leffen-visa-update/|title=Leffen visa update}}</ref> However, due to his visa going through additional processing resulting from his previous deportation from the US, Leffen was ultimately unable to attend EVO 2016.<ref>{{cite web|url=https://web.archive.org/web/20230808024633/https://www.espn.com/esports/story/_/id/17063369/visa-delays-hold-leffen-back-attending-evo|title=Visa delays hold Leffen back from attending Evo}}</ref>

Despite being unable to travel to the United States, Leffen was still able to compete in [[Canada]], and entered majors in the spring of 2016. At {{Trn|Enthusiast Gaming Live Expo}}, Leffen lost to {{Sm|Axe}} and {{Sm|Duck}} to finish an underwhelming 7th. However, he rebounded at {{Trn|Get On My Level 2016}}, where he defeated Mew2King 3-2, Armada 3-1, Hungrybox 3-2, and Mang0 3-1 to take 1st place without losing a set. Leffen's GOML run is often regarded as one of the most difficult and impressive tournament runs in ''Melee'' history, as he defeated all four active Gods in succession.

Leffen's visa was finally accepted on October 3rd, 2016, allowing him to compete in the US again.<ref>{{cite web|url=https://web.archive.org/web/20230808025130/https://www.espn.com/esports/story/_/id/17705825/leffen-receives-visa-allowed-return-usa-compete-smash-tournaments|title=Leffen receives athlete visa, approved to compete in the US}}</ref> Leffen's first tournament back in the US was {{Trn|The Big House 6}}, where he elected to [[sandbagging|sandbag]] with secondaries, placing 17th. He ended the year ranked 5th on the [[SSBMRank 2016]], largely due to his lack of attendance compared to the other top players.

===2017-2020: EVO 2018 victory===
After finally returning to full-time competition, Leffen was unable to replicate his dominance of 2015. While still regarded as a tournament threat, he failed to win a major throughout 2017 and the first half of 2018, ending 2017 ranked 6th on the [[SSBMRank 2017]]. Leffen additionally began competing in other fighting games at this time, including ''{{iw|wikipedia|DragonBall FighterZ}}''.

Leffen's biggest tournament win to date came at {{Trn|EVO 2018}}, where he finally won the coveted title after many years of coming short. After going down 0-1 vs. Hungrybox in winners' semis, he didn't drop a single game for the rest of the tournament; he made the comeback against Hungrybox to win 2-1, and then easily defeated Plup 3-0 in winners' finals, followed by a 3-0 over Armada in grand finals to win one of the largest ''Melee'' tournaments of all time. Leffen's EVO 2018 run is often regarded as one of the most dominant tournament runs in ''Melee'' history.

At {{Trn|Super Smash Con 2019}}, Leffen took 1st place, winning his first major since the EVO victory, notably 6-0-ing Hungrybox.

===2020-present: Post-pandemic era===
Leffen was one of the top players most heavily affected by the [[COVID-19]] pandemic, due to his location in Europe. He was unable to enter many North American online events, as they were often region-locked for European players due to high ping issues. During this time, Leffen was perceived to be a top three player in the world, alongside Zain and Mang0, but it was difficult to compare his skill against other players due to a lack of results.

He received an automatic invite to {{Trn|Smash Summit 11}}, the first post-pandemic LAN major, but was unable to attend due to further visa problems.<ref>{{cite web|url=https://web.archive.org/web/20230808025905/https://dotesports.com/fgc/news/leffen-unable-to-attend-smash-summit-11-due-to-visa-issues|title=Leffen unable to attend Smash Summit 11 due to visa issues}}</ref> As such, in 2021, he attended only one tournament in North America: {{Trn|Smash Summit 12}}, where he placed 5th.

Leffen began entering more North American events starting in 2022; by this time, he also had picked up another fighting game, ''{{iw|Wikipedia|Guilty Gear Strive}}'', and competed in that title full-time alongside ''Melee''. Despite splitting time between the two games, Leffen still proved that he was capable of winning a major and defeating the best players in the world. His first post-lockdown victory came at {{Trn|Battle of BC 4}}, where he beat {{Sm|aMSa}}, Hungrybox, and Zain twice. In 2023, he won {{Trn|Ludwig Ahgren Championship Series 5}}, where after losing to {{Sm|Joshman}} and {{Sm|Cody Schwab}} in pools, he managed to make it out of the Swiss bracket and into winners' top 16. He beat Hungrybox 3-0, Zain 3-2, Cody Schwab in winners' finals, and Zain once again in the runback.

During this time, Leffen also developed a secondary {{SSBM|Sheik}} as a counterpick to {{SSBM|Marth}}, due to his previous difficulties against Zain in the Fox-Marth matchup. He used Sheik to double eliminate Zain at both Battle of BC 4 and LACS 5, and is one of the few players who holds a positive record against Zain post-pandemic.

===Other ''Smash'' games===
Leffen also played ''[[Project M]]'' at a high level for a while, and was known as one of the best players of {{PM|Captain Falcon}}, {{PM|Fox}}, and {{PM|Zero Suit Samus}}.

Leffen has occasionally played ''[[Super Smash Bros. 4]]'', and notably pioneered the usage of {{SSB4|Diddy Kong}}'s up throw to up air combo.

Upon ''[[Super Smash Bros. Ultimate]]''{{'}}s release, Leffen often streamed the game and offered his own opinion on the metagame. He was one of the early pioneers of using {{SSBU|Pokémon Trainer}}, who he has since used successfully in tournaments. Leffen briefly dropped Pokémon Trainer in favor of {{SSBU|Roy}} and {{SSBU|Pichu}} in April 2019, citing that Pokémon Trainer was not worth the effort, but he would eventually return to using the Trainer. Leffen also began labbing Joker upon his release and discovered an [https://www.youtube.com/watch?v=nFDh3c_6JmI infinite lock technique] performed by repeatedly using short-hopped {{Mvsub|Joker|SSBU|up aerial}}s under the opponent while they are on top of a platform. The technique has since been named "Leffoble" in honor of him.

At the end of April, Leffen announced his semi-retirement from ''Ultimate'' singles, mainly citing the smaller scene in Sweden and issues with online play making it difficult for him to get any meaningful practice.<ref>{{cite web|url=https://twitter.com/TSM_Leffen/status/1120003964995551234|title=Leffen's first ''Ultimate'' retirement}}</ref> However, the release of {{SSBU|Hero}} saw his return to the game, and he intended to compete in {{Trn|EVO 2019}}, but issues with his visa kept him from doing so. Leffen continued to enter for both ''Melee'' and ''Ultimate'' at major tournaments such as {{Trn|Super Smash Con 2019}}, and although he put more importance towards ''Melee'', he still found success in ''Ultimate'', with set wins over {{Sm|Tweek}}, {{Sm|Salem}}, and other top players. Following his first place at {{Trn|DreamHack Winter 2019}}, Leffen announced he would once again be putting ''Ultimate'' on the backburner, instead focusing on ''Melee'' and other fighting games. He has since been critical of the game, which has [[Smasher:Leffen#Opinion on Ultimate|brought about some controversy]].

==Playstyle==
With Fox, Leffen is known for his consistent execution and movement, and boasts solid fundamentals in all aspects of the game, using a methodical and efficient approach, making him a very well-rounded player. Leffen has both a great [[neutral game]], as he rarely overextends or overreaches in games even against weaker opponents, and a solid [[combo]] game, especially against fastfallers. He is renowned for his proficiency against {{SSBM|Falco}}, {{SSBM|Peach}}, and other Foxes, having made his first upsets against the [[Five Gods]] in those matchups. Leffen's prowess against Peach is so great that even {{Sm|Armada}}, the best Peach in the world, would primarily opt for the Fox [[ditto match|ditto]] in tournaments instead, generally only playing Peach on {{SSBM|Final Destination}}. He is also arguably the best Fox player in the world at edgeguarding, which heavily contributes to his success in the Fox ditto and several other matchups.

While Leffen is well-rounded, he undoubtedly focuses on mental fortitude and adaptation more than technical play. Leffen once stated in an interview that he believes many high-level players are held back by "flowchart" behavior that he is able to exploit. This is clearly exemplified by his ability to "clutch" out sets from losing positions, even from 0-2 deficits. Despite this, he still puts in the work to lab certain matchups or situations that give him trouble, showing his solid work ethic; he's even known to lab other miscellaneous characters solely to push the metagame forward. Along with Armada, he practices with {{Sm|Snowy}} for the Jigglypuff matchup and has flown him out to events such as Summit in order to prepare for facing Hungrybox in bracket.

Prior to his establishment as a top 5 player, Leffen had noticeable trouble against punish-heavy players. Despite his strong fundamentals, he struggled if his opponent could overwhelm him technically, leading to losses against {{Sm|Silent Wolf}}, {{Sm|Westballz}}, and {{Sm|Javi}}, among others. He also could not defeat {{Sm|Mew2King}} for a long time, even after he had upset the rest of the Five Gods, because of that aforementioned weakness. Leffen was also noted to be fairly poor at the {{SSBM|Samus}} matchup, having, at one point, losing records with {{Sm|HugS}} and {{Sm|Duck}}, both of whom are considered far below his skill level. He has also lost three times to {{Sm|Plup}} in solo Samus sets. However, he has since overcome these weaknesses and no longer drops sets as frequently to these types of players, most notably not having lost to solo Samus since 2018.

==Controversy==
Despite being considered one of the best professional smashers in ''Melee'', Leffen has led a controversial career as a Smasher, primarily due to a history of aggressive and rude behaviour towards other competitors, on- and offline.

===Ban from European tournaments & Evidence.zip===
{{incomplete|A summary of Leffen's defences could be useful to add balance to this section}}
On 9th February 2013, Leffen was banned from Swedish ''Smash'' tournaments following extensive evidence of abuse towards various players in the scene.<ref>[https://smashboards.com/threads/leffen-is-banned.333990/ Original ban post]</ref> Alongside the ban, {{Sm|Armada}} provided a large "Evidence.zip"<ref>[https://archive.org/details/evidence_202009 Original Evidence.zip (Posts Only)]</ref> featuring three documents; one 54-page Word document archiving numerous [[SmashBoards]] posts, one 14-page document of Swedish forum posts, and a miscellaneous archive compiled by {{Sm|Mike Haggar}} including SmashBoards and SmashFinland posts.

At the time, the official reasoning behind banning Leffen was the following;
# Demoralising comments towards newer players, demotivating them and thus hindering scene growth.
# Libel against numerous players, accusing them of stealing, lying, and even taking drugs, to destroy their image.
# Ableism against those with disabilities, diseases, etc.
# Spreading personal information.
# Extremely poor sportsmanship, including demeaning teammates in Doubles.
# Causing a spike in drama since joining the scene.
# Freezing people out of conversations through ignoring them, standing in front of them in conversation, and talking over them when doing so; the person this was done against was notably disturbed by this behaviour. Made fun of this individual's hearing disabilities.
# Sabotaging people's Smashfests and trips through manipulation.

After noticing his poor behavior, Swedish tournament organizers and other ''Melee'' professionals of his caliber gave him repeated warnings concerning his attitude. In August 2012, Leffen was eventually threatened with a ban from tournaments if he did not improve his attitude, but he did not take the claim seriously.

The discussion group announcing his ban compiled a significant amount of evidence of his poor behavior into a downloadable archive, and demanded that Leffen create a lengthy apology about all of his wrongdoings and how he would change his behavior in the future, should he return to the community. On March 21st, 2013, [http://www.twitlonger.com/show/n_1rjbt3e Leffen made his public statement asking for forgiveness]; despite this, he was not immediately unbanned, and ended up missing almost one year's worth of local tournaments.

====Unban====
On January 24th, 2014, it was announced by {{Sm|Armada}} that the Swedish ban on Leffen was no longer in place [https://facebook.com/events/182185045312694/permalink/206413366223195/?stream_ref=2]. Despite the ban, Leffen remained a relatively controversial figure in the community, especially on social media sites such as Reddit and Twitter, due to his vitriolic comments. Evidence.zip remained notorious in the community, notably being mentioned in {{Sm|Chillindude829}}'s infamous "Respect Your Elders" diss track, released in 2015.

====Evidence.zip Testimony Leak====
In January 2024, alongside a ban appeal,<ref>[https://www.youtube.com/watch?v=SR9A70YKxf4&ab_channel=Hax%24Archive Hax$'s January 2024 Ban Appeal]</ref> {{Sm|Hax$}} leaked the 2013 Evidence.zip testimonies.<ref>[https://drive.google.com/drive/folders/1YgdxjDbB1nN8lxghXrrBP2oxAmaDGQGC Evidence.zip Testimonies]</ref> This was done under the justification of being the only remaining community member still holding them, and seeking to preserve the archive. Out of the nine testimonies, seven were revealed, with two being held back due to their particularly sensitive natures.

Some new facts can be extracted from these testimonies, adding further context to Leffen's original ban from the Swedish ''Melee'' scene;
* Leffen was notably insulting in the [[Melee Back Room]], with {{Sm|Strong Bad}} citing some particularly aggressive posts.
* Hax$ mentions a stream where Leffen, seemingly unprovoked, attacked his character and repeatedly resorted to ad hominems in debate, and subsequently receiving repeated online harassment ever since. He additionally criticises Leffen for the way he handled his ban in 2013, calling a post he made in the [[Melee It On Me]] [[Facebook]] group manipulative.
* C discusses a road trip where Leffen would deliberately and forcefully rock his seat back against their legs while locked against it, causing severe pain, in addition to a large-scale harassment campaign against them.
* ROFL observes the negative effects Leffen's manipulation had on those around him; previously, he held respect for Leffen, but felt it decline over time as a result of this behaviour.
* {{Sm|Zneffy}} discusses a time where they received an unprovoked verbal attack from Leffen following a match, followed by a non-apology where he talks down to Zneffy.
* {{Sm|VJ}}, a tournament host, while never personally having conflicts with Leffen, discusses the reason why they made a personal decision to never allow Leffen in their tournaments, to the point of considering calling the police. In general, he discusses Leffen's elitist behaviour and general dishonesty, on top of his conflicts with other players.

Additionally, a letter to [[GENESIS 3]] was enclosed, which had compiled the testimonies and demanded Leffen be banned from the tournament.

====Censorship allegations====
In December 2020, {{Sm|Samox}} released a documentary titled [[Metagame (documentary)|Metagame]], compiling the history of the ''Melee'' metagame and following up from [[The Smash Brothers]]. In this documentary, Evidence.zip is mentioned when discussing Leffen, but was cut from later releases following criticism from Leffen himself. To make up for it, in June 2021, a bonus episode titled "Godslayer" was released, which portrayed Leffen in a more positive light. This move was blasted by Hax$, accusing the Metagame documentary of being "censored" due to manipulation from Leffen,<ref>[https://www.youtube.com/watch?v=msy4E3ScZVk "evidence.zip 3"]</ref> in addition to numerous other allegations against Leffen's character. He evidenced this with the unusual timing of the situation, given Leffen's tweets blasting the Metagame documentary on his end.

In January 2024, Samox released a statement.<ref>[https://twitter.com/_samox_/status/1750634235461865944 Samox's Statement regarding Metagame's portrayal of Leffen]</ref> He notes that the Evidence.zip mentions total 20 seconds, that his portrayal of Leffen was hardly positive, and, most notably, that someone threatened to sue him for the use of the Evidence.zip content. He specifically noted that Leffen wasn't the party who threatened to sue.

===Ban from commentary===
{{Citations missing}}<!--This is definitely true, just needs a citation to bring up to wiki standards-->
At [[Heir II the Throne]], Leffen was banned from commentary on all future European Smash Circuit events for saying that it wasn't a "serious" tournament and players were playing their secondaries and not trying. Leffen notably compared the tournament to [[The Foundry]], a series notorious for its relaxed and non-competitive atmosphere. Many argued that the TOs had overreacted in their decision, and that a full ban was an excessively harsh punishment.

===Opinion on ''Ultimate''===
Despite focusing on ''Ultimate'' for a year, Leffen has been openly critical about the game, even going as far as to say that playing top-level ''Ultimate'' "is just pure fucking torture to [him]."<ref>{{cite web|url=https://twitter.com/TSM_Leffen/status/1200853073935159301|title=Leffen's Tweet before DreamHack Winter 2019}}</ref> As a result, he has butted heads with several other ''Ultimate'' professionals. Most notably, on September 26th, 2020, he argued with {{Sm|Rickles}} that streaming ''Ultimate'' was painful to him, that he would "rather flip burgers at mcdonalds [sic] if it paid the same amount," and that streaming ''Ultimate'' was harder than holding a minimum wage job.<ref>{{cite web|url=https://twitter.com/TSM_Leffen/status/1310010198002728961|title=Flipping Burgers Tweet}}</ref> This Tweet was met with backlash and mockery from the community: users noted the difficulty of minimum wage jobs especially during the COVID-19 pandemic while several Smashers such as {{Sm|Axe}} recounted how they hated working at their minimum wage jobs before they went professional. The Tweet eventually caused "Leffen" to trend on Twitter.<ref>{{cite web|url=https://twitter.com/iamrickles/status/1310586002747076609|title=Archived Minimum Wage Tweet}}</ref> Leffen would later delete and apologize for his minimum wage Tweet.<ref>{{cite web|url=https://twitter.com/TSM_Leffen/status/1310482233170579456|title=Leffen apologizing for his Tweet}}</ref>

===Libel allegations===
On July 2nd, 2020, amidst a wave of sexual harassment allegations in the community, artist Jisu posted a tweet where she called out ZeRo for showing her hentai and explicit Craigslist ads when she was 15.<ref>{{cite web|url=https://twitter.com/JisuArtist/status/1278843558401675264|title=Jisu's statement}}</ref> ZeRo later responded, admitting that he looked at hentai, but denied that he had shown it to her, nor would he show it to an entire room of people. He also denied showing her the ads.<ref>{{cite web|url=https://docs.google.com/document/d/e/2PACX-1vQJpUoVhxCgh9_75K8WAYN56d5yvxINwy3c3fPFCMkoEnThJs4qSIk0GY0T8AJ0T_ySDGxhrixCs0ng/pub|title=ZeRo's response to Jisu}}</ref> Following this defense, many people started to target Jisu for "clout-chasing." Leffen, however, would defend Jisu's claims by claiming that he saw ZeRo show people hentai in public, a statement that was backed up by a screenshot from an anonymous user later sent to Leffen.<ref>{{cite web|url=https://www.twitlonger.com/show/n_1sra9ee?new_post=true|title=https://www.twitlonger.com/show/n_1sra9ee?new_post=true}}</ref> ZeRo would later confirm this and many other allegations made about him to be true several days later. <ref>{{cite web|url=https://www.twitlonger.com/show/n_1sraama|title=ZeRo's final statement}}</ref>

However, on June 25th 2021, {{Sm|Technicals}} would make a YouTube video where he challenged a vast majority of Jisu's allegations towards ZeRo.<ref>{{cite web|url=https://www.youtube.com/watch?v=luQgX3zEExU|title=Technicals' video}}</ref> In the same video, Technicals featured a brief section where he interviewed ZeRo about Leffen's allegations. ZeRo stated that he didn't remember any of the events that Leffen claimed to have happened. He would later state in the interview that he felt as if "he was trapped by Leffen into being pressured into admitting the truth" due to all of the allegations against him, and that by apologizing for Leffen and Katie, he would be creating a false agenda that Jisu's story would be correct. Both Leffen and Jisu have yet to respond to Technical's and ZeRo's allegations.

On September 9, 2022, ZeRo would release a video where he accuses Leffen as the biggest instigator during the allegations made against him, as he claimed Leffen lied about a story regarding ZeRo sharing hentai with Leffen and Japanese players when they housed together for {{Trn|Apex 2013}}, and also accused ZeRo for exchanging hentai with fans without verifying their age. A fan that ZeRo sent hentai to would add an addendum to their statement saying while ZeRo had sent her hentai without confirming their age, they were an adult at the time and also requested ZeRo send it to them.<ref>{{cite web|url=https://twitter.com/SHSLRuby/status/1408539105743474692|title=Clarification on Leffen accusation from fan}}</ref> ZeRo ultimately accused Leffen for profiting off the drama while tarnishing ZeRo's name in the process.<ref>{{cite web|url=https://www.youtube.com/watch?v=ADUYFK-KJng|title=THE LAWSUIT IS OVER}}</ref>

===Feud with Hax$===
{{incomplete|A summary of Hax and Leffen's original feud during the SmashBoards era, the circumstances of Evidence.zip, and adaptation of the post-2021 controversies from Hax's SmashWiki page could be useful for this section}}

==Trivia==
*Leffen was commonly considered a villain in the ''Smash'' community due to his reportedly rude behavior and trash-talk. He claimed that he enjoyed his given title due to the community's need of someone to root against, although a controversy existed over whether he should embrace it or not.
**Leffen has also been compared to {{iw|bulbapedia|Gary Oak}} from the ''Pokémon'' anime due to their similar personality and appearance.
*Leffen is the subject of the two-season Red Bull documentary [[Cultivation Leffen: Resurrection]], which chronicles the time period from his initial ban through his visa issues and his triumph at [[Get On My Level 2016]].
*Leffen's lifetime set count against Mew2King (9-17) is his worst set count against a god (excluding PPMD).
*Leffen is infamous for a spate of losses against {{SSBM|Samus}} players {{Sm|HugS}}, Plup, and {{Sm|Duck}} in 2015 and 2016 after having mocked Chillin's losses to the same character on Twitter.
*Leffen is the first person to four-stock Armada in a bracket, doing so twice at [[FC Smash 15XR: Return]] and at [[Smash 'N' Splash 4]].
*Leffen, along with {{Sm|Tafokints}} and {{Sm|Zomba}}, holds the title of the most money won in a single money match. He won $1,000 on three different occasions:
**At Apex 2015, where he defeated {{Sm|Mango}} in bracket 3-1 after betting on it following his [[Leffen vs. Chillin (Apex 2015)|salty suite against Chillin]].
**At {{Trn|DreamHack Winter 2015}}, where he defeated {{Sm|SFAT}} in a money match 5-1.
**At {{Trn|The Kid, the Goat, and the Mang0}}, where he won a bet against Mango as to who would win the loser's quarter-finals match between {{Sm|Lucky}} and {{Sm|Swedish Delight}}; Leffen bet on Swedish Delight, who ultimately won the set.
*Leffen is sometimes referred to by his nicknames ''Yung Leff'' or ''Big Leff''. Depending on how he plays and if he wins or loses, the adjective used can vary (''Humoungous Leff'' or ''Massive Leff'' when winning; ''Small Leff'' or ''Minuscule Leff'' when losing). He has also been referred to these names by ''Dragon Ball FighterZ'' commentators.
*Outside of ''Smash'', Leffen has competed in both ''Dragon Ball FighterZ'' and ''Guilty Gear: Strive'' events. He is currently the only ''Smash'' player who was invited to a non-''Smash''-related Summit event (''DBFZ''{{'}}s [https://start.gg/tournament/summit-of-power/events Summit of Power]), as well as the only player to win an official EVO event for both platform and traditional fighting games (having also won [https://www.start.gg/tournament/evo-2023/details EVO 2023] for ''Guilty Gear: Strive''). He has since retired from ''Dragon Ball FighterZ'', citing Toei's meddling in tournaments, and Arc System Works' way of patching as the two reasons he does not enjoy the game anymore.
*Leffen is the subject of a popular Twitter parody account known as the [https://www.twitter.com/DeepLeffen Deep Leffen Bot], a natural AI learning model created by a PhD student that is trained on Leffen's tweets, various ''Smash'' subreddits, and other "unsavory source materials". The bot is popular in the ''Smash'' community for its humorous and creative content output. Although he initially blocked the bot's account on Twitter, Leffen has since come around and praised the bot for its artistic and comedic value.<ref>{{cite web|url=https://twitter.com/tsm_leffen/status/1251214851009101826|title=Leffen's endorsement of Deep Leffen}}</ref>
*Despite being a sandbagging secondary, Leffen's {{SSBM|Mewtwo}} reached the top of the ranked European [[Project Slippi]] leaderboards (and taking offline sets locally against top European players) under the alias of '''MewTwoMan'''.
