PPMD, formerly known as Dr. PeePee, is a top professional Melee player who mains Marth and Falco. He is Twitch's older brother. His smasher tag was known as "Dr. PeePee" until mid-2014, when he became sponsored by eSports organization Evil Geniuses and formally changed his tag to his former abbreviation "PPMD". PPMD is currently ranked at the 0 position on the North Carolina Melee Power Rankings and 6th on the 2015 SSBMRank, and was formerly ranked 7th on the North Carolina Brawl Rankings. He teams with LoZR, the 4th best player in North Carolina; the duo have shown to be powerful with excellent teamwork. He is considered to be one of the top six players in the world; he is widely viewed as one of the top Falco players in the world, and is also considered one of the best Marth players in the world, alongside Mew2King, having taken sets off of Armada, Mew2King, and Leffen and winning Apex 2015 predominantly using Marth.
PPMD has also recently been the only Falco player that can beat Hungrybox's Jigglypuff (as Mango usually uses Fox against Hungrybox and formerly did Jigglypuff dittos). He is also considered the best Marth player against floaty characters, as seen by his strong results against Armada's Peach with his Marth.
PPMD started playing competitively in 2007 as a Mario main before his transition to Falco and Marth. He became famous in the Smash scene for his performance at Revival of Melee 2 in 2010, where his Falco placed higher than Mango's. He won his first national at Revival of Melee 3, and later won Pound V as well, winning two sets against Armada in grand finals. Early in his career he frequently teamed with Everlasting Yayhuzz and LOZR in the teams known as "Catfish". At Apex 2012, he defeated several notable smashers such as Silent Wolf, SFAT, and Wobbles, before losing to Armada and then being eliminated by Javi 0-2 in losers' quarters, placing 5th overall. He also placed 1st at Zenith 2012, winning two sets against Mew2King in grand finals, 2nd at the European tournament Smashers' Reunion: Melee Grande, taking a set off of Armada in grand finals before losing an extremely close second set 3-4, and 1st at Kings of Cali, defeating Mango in two sets of grand finals.
Around this time, due to growing troubles against Mew2King on Final Destination, PPMD began developing his Marth. While at Zenith 2012 Mew2King managed to defeat him in Marth dittos, PPMD 3-0ed Mew2King in a Marth ditto set several months later, and has since maintained a largely positive record against him in that matchup.
At Apex 2013, PPMD placed 2nd, losing to Armada 0-3 in winners' finals and then winning the first set of grand finals against him 3-2, but once again losing the second set, 1-3. Starting with Tipped Off 9 in late 2013, PPMD had a dominant period where he managed to win every tournament he entered for half a year; he won Apex 2014 without dropping a set, defeating aMSa 2-0 to make into the top 8, then defeating Mango 3-1 in winners' semis, and Mew2King 3-0 and 3-1 in winners' finals and grand finals, respectively (including two 4-stocks against Mew2King, with one being a Marth ditto on Final Destination during the second game of winners' finals).
PPMD was picked up by professional eSports organization Evil Geniuses on May 9th, 2014, and is currently sponsored by them. Around the time of his sponsorship he changed his tag from Dr. PeePee to PPMD.
PPMD later won SKTAR 3, defeating Armada 2-1 in winners' semis, Mango 3-1 in winners' finals, and Mew2King 3-1 once again in grand finals (with another 4-stock in the final game). Because of winning SKTAR 3, PPMD successfully qualified for the championship bracket at MLG Anaheim 2014.
At MLG Anaheim 2014, PPMD only lost one set in his pool, to Leffen 2-3. He was seeded in winners' semis in the championship bracket, where he lost to Mango 2-3. He then eliminated Leffen 3-1 in losers' quarters, but was eliminated by Mew2King 2-3 in losers' semis, placing 4th overall. Three weeks later, at EVO 2014, PPMD made it to the finals of the winners' quarters pool against Hungrybox, but lost 1-2. He defeated PewPewU 2-0 in losers' bracket to make it into the top 8, where he eliminated Fly Amanita 2-1 and Mew2King 2-0 before being eliminated by Armada 0-2, placing 4th overall.
PPMD was also invited to participate in the E3 2014-held Super Smash Bros. Invitational tournament to play Super Smash Bros. for Wii U. He used Fox in the tournament, and won the Fan-Favorite Tournament after being eliminated in the quarterfinals.
Despite being one of the best Melee players of all time, PPMD is known for rarely going to tournaments (outside of small NC locals) - he has recently only traveled to the largest tournaments, such as Apex 2014, MLG Anaheim 2014, and EVO 2014. PPMD has revealed that this is mainly due to personal issues, specifically depression.  Despite his inactivity, he still managed to claim 1st place at Apex 2015, defeating Armada 3-2 in winners' semis, and Leffen 3-2 in winners' finals. In grand finals, he lost the first set to Armada 2-3, but defeated him in the second set 3-0 to win the tournament. He did not attend a single event afterward until EVO 2015, although he had planned on attending I'm Not Yelling! and some other tournaments. At EVO he finished 3rd after being eliminated by Hungrybox. At Get Smashed at the Foundry #69 PPMD won, playing mostly Mario, Fox, and Falcon.
PPMD did not attend EVO 2016 due to health issues involving physical fatigue and low testosterone. PPMD stated he probably wouldn't have had the energy to compete even if he did recover before the tournament. 
Although PPMD's technique is very refined, he is not known for his technical prowess as much as other top players such as Westballz and PewPewU. Rather, he is renowned for his strong mental game and extremely threatening and precise dash dance spacing, both of which are part of his mildly aggressive play-style that is very conservative and methodical compared to other top players. As part of this playstyle, PPMD almost never consciously makes a sub-par decision in a match in an attempt to gain advantage or "disrespect" his opponent, even when greatly ahead in a game. This leads to PPMD having what is arguably the best neutral game play in the world, and even top players, such as Armada, have commented on how difficult it is to get an opening against him.
As Falco, PPMD focuses on intelligent laser spacing and maintaining stage control with carefully spaced attacks, while punishing opponents who make mistakes with consistent shine combos and exceptional reads on the foe's movement. As Marth, PPMD utilizes his impeccable dash dance spacing, precisely spaced down tilts, and timely rising forward aerials to completely wall his opponents out, making it far more difficult to hit him compared to the vast majority of other Marth mains. This playstyle has seen him great success against floaty characters that most Falco and Marth mains have recently struggled with. He is considered the best Falco and Marth in the world against Peach, and the best Marth player in the Marth ditto and against Sheik, a character historically considered one of Marth's most difficult matchups in Melee. His prowess against floaty characters with Marth has seen him taken a best-of-5 set against Hungrybox in Project M, using exclusively Marth.
While PPMD is one of the best in the world at the neutral game, he does not have as strong of a punish or edgeguarding game compared to other top players such as Mango and Mew2King, although it still remains quite strong. This is especially prevalent in the Marth v.s. Fox matchup, where PPMD often does not convert openings or grabs to lethal edgeguarding situations like Mew2King will. He was additionally susceptible to psychological pressure despite being a very psychological player himself, especially after he became known as one of the best in the world. PPMD was very hard on himself after a loss or making a mistake, and would grow anxious during tournaments where he was the favorite to win against other top players, which adversely affected his tournament results. However, after having issues with depression, PPMD has changed his mindset to what he describes as "acceptance," where he would respect any outcome of a tournament, even if he does not win or place as well as projected. This has overall stabilized his tournament placings and he is no longer as susceptible to sporadic tournament placements while actively participating in tournaments.
