Leon is a French Ultimate Lucina player from Vitry-sur-Seine, Greater Paris Area, who is considered the best Lucina player in Europe. Leon was originally a Brawl veteran who skipped most of Smash 4's competitive lifespan and came back in the spotlight with Ultimate's release. Despite the hiatus, he quickly prove that he was still able to hold his own against Europe's best players. He has defeated several top players including Glutonny, Mr. E, Charliedaking, Flow, Oryon, Homika, and PeW, and is currently ranked 28th on the European Smash Rankings. Despite being considered as a legendary Brawl Marth player, he prefers using Lucina in this game. His Lucina’s playstyle is known for its patient movement and spacing, in addition to retaining some of his aggressive play from Brawl.
Leon made his debut in Melee, maining Roy. He surprised many players at Epita Smash Arena, his first tournament. While he was not aware of advanced techniques at the time, he had developed his own playstyle and combos with Roy, and managed to reach a decent place.
His golden era occurred in Brawl. He originally mained Peach and was often referred as the French Brawl Champion, since he placed first in most of the Brawl tournaments in France in 2008 (and thus placed 1st in the 2008 Rankings) with her. Counting tournaments in anime conventions, Leon won 9 tournaments in 2008, 7 in a row, 3 being Bushido Impact events. His undisputed #1 spot in France then suffered from the debuts of Glutonny, who three-stocked him in WF at Bushido Impact 8th Impact, Glutonny's first tournament. As time passed by, he progressively started to play Marth, as a co-main to his Peach at first, before solo-maining the swordsman around 2010. He continued to place high in tournaments that he enters, though his extremely aggressive playstyle occasionally works to his detriment, as seen here. Leon frequently attended major tournaments in North America, such as SKTAR and the Apex tournament series, where he has achieved significant placings. He has taken sets off of top players such as DEHF. He moved to Toronto after Apex 2014, but moved back to France after 5 months. Leon was ranked at the 0 position on the Brawl Southern Ontario Power Rankings. He was formerly a member of the Bushido Impact staff starting in July 2009. He was previously ranked 7th on the French Power Rankings and 22nd on the 2014 SSBBRank.
Even though he was inactive in Super Smash Bros. for Wii U, Leon gave the game a chance upon its release, playing Zero Suit Samus main. He was previously ranked 1st on the French Power Rankings before his inactivity.
He also still plays Project M, and is currently ranked 4th on the French Project M Power Rankings.
