The 18-year-old survived all three Round Pools before he fell down into the Losers' Bracket following a defeat to Takuto "Kameme" Ono in his opening match of the Singles Bracket. From there, he faced a challenge from Enrique "Maister" Hernandez Solis, losing one game but closing it out 2-1, before effortlessly beating every opponent that followed in clean 2-0 fashion up.
The 2-0 streak continued into the Final Singles Bracket, as Ezra "Samsora" Morris' Peach and William "Glutonny" Belaid's Wario also failed to alter the final score line in their favour.
Only Tweek and the PokÃ©mon Trainer he had chosen stood between MkLeo and the trophy in the grand final. While an early 2-0 for Tweek looked promising, MkLeo turned it around and into a 3-2 for himself in the Grand Final.
The reset that followed seemed to take its toll on Tweek while only boosting MkLeo's confidence as a 3-0 earned him the title on his first attempt at an EVO tournament, helping Smash break viewership records for the highest peak viewership in EVO history at over 279,000 viewers.
While only 18, MkLeo has been competing since 2016 in Super Smash Bros. for Wii U. One of his early tournaments, Get On My Level 2016, saw him face the PGR-ranked and widely considered #1 Gonzalo "ZeRo" Barrios and take him to five games. MkLeo went on to become the only Wii U player to take the top spot other than ZeRo in PGR V5, the final ranking list of the era.
Since the release of Super Smash Bros. Ultimate in December 2018, MkLeo has maintained the #1 ranking, while his EVO opponent Tweek holds #2, and has won eight tournaments playing as Lucina, Wolf and Ike, with DLC character Joker becoming his new main since MomoCon 2019 in May.
MkLeo will next play at Super Smash Con 2019 later in August where he will be hoping for a repeat performance and another title under his belt.
