MkLeo

His weakest performance in a major tournament came at Umebura Major in Japan, where he placed 33rd; this was also the first tournament where he used Joker, newly released character, competitively.

His success against the scene's other top players earned MkLeo the top position in the inaugural Panda Global rankings for Ultimate.

Leonardo López Pérez (born January 20, 2001), better known as MkLeo and sometimes Leo, is a Mexican professional Super Smash Bros. player.

MkLeo won his first Smash Bros. tournament at the age of eight when he took first place at the Super Smash Bros. Brawl competition at Anime Expo Mexico TNT 2009.

The Panda Global Rankings 100, which listed the Top 100 Wii U players from the game's release through the release of Ultimate, placed MkLeo as the 3rd best player of all time behind ZeRo and Nairoby "Nairo" Quezada.

The final Panda Global rankings for Super Smash Bros. for Wii U listed Marth as the main character that he played and Cloud Strife and Bayonetta as his secondary characters.

At 14, he rose to prominence in Super Smash Bros. for Wii U after defeating Ramin "Mr. R" Delshad to win Smash Factor 4, right after Delshad took 2nd place at Evo 2015.

He began competing internationally in 2016, culminating with a win at 2GGT: ZeRo Saga in December.

At that event, he defeated several of the game's prominent players, including Gonzalo "ZeRo" Barrios, Larry "Larry Lurr" Holland, and James "Void" Makekau-Tyson.

Following the win at 2GGT, MkLeo was jointly signed by Echo Fox – who signed him and six other fighting game players at the same time to build the largest roster of fighting game players in esports – and Most Valuable Gaming.

MkLeo, who was not able to obtain a travel visa to attend Genesis 3 at the start of 2016, announced after his win at 2GGT that he would go on to win Genesis 4, which was to be held the next month.

At Genesis 4, he again finished in 1st place, defeating Elliot "Ally" Carroza-Oyarce, who had won the Smash tournament at Evo 2016.

He was the youngest player to make the top 8 in the tournament series' history.

Playing alongside Ally, the pair also won the tournament's doubles competition.

MkLeo had mixed results throughout the rest of 2017, with disappointing results including taking 13th place at Frostbite 2017 in February, and 65th place at Evo 2017 in July.

However, he won GameTyrant Expo 2017 at the start of October, and took second place at CEO 2017, falling to ZeRo.

At the end of the year, MkLeo won the 2GGC Championship, this time defeating ZeRo in the finals, and claimed the tournament's $20,000 first place payout.

Prior to the release of Ultimate, he was ranked as the best player in the world at Super Smash Bros. for Wii U for the first half of 2018.

Between Wii U and Ultimate, MkLeo has won approximately 35 major tournaments.

In January 2018, ZeRo announced his retirement from professional Smash competition.

As ZeRo had long been considered the best Super Smash Bros. for Wii U player in the world, this created an opening for MkLeo to seize the top spot.

He put together a string of impressive performances over the year, including wins at Genesis 5, Evo Japan 2018, CEO 2018, Get On My Level 2018, and SwitchFest 2018.

MkLeo was unable to attend Evo 2018 due to chickenpox, but was able to attend Super Smash Con 2018 shortly thereafter, where he claimed another 1st-place finish.

These wins resulted in MkLeo taking the top spot in the final bi-annual Panda Global rankings of Wii U players before the release of Ultimate.

Smash Ultimate was released in December 2018, and MkLeo had strong showings at several tournaments held shortly after the game's launch.

He won one of the first Ultimate tournaments, Smash Conference United, and took fourth place at Glitch 6, both in the month of January.

The following month, he won Genesis 6, considered the first premier tournament in Ultimate.

The win was his third consecutive title at that tournament series and made him a front-runner for best player in the world at the new game.

He was widely considered the best Super Smash Bros. Ultimate player in the world during the pre-covid era, and was number one in the Panda Global Rankings for the first and second half of 2019.

These include the Ultimate bracket at Evo 2019, the largest offline tournament by number of entrants in the Smash franchise's history, and the inaugural Smash World Tour in 2021, a year-long worldwide tournament series.

From May 2019 until March 2022, MkLeo did not place lower than 2nd at any offline Ultimate events, 35 straight tournaments.

In the five semi-annual Panda Global rankings released over the competitive lifespan of Super Smash Bros. for Wii U, MkLeo was ranked 19th, 8th, 2nd, and 4th before taking first place in the final ranking.

In the first half of 2019 he won three other major tournaments, MomoCon 2019, CEO 2019, and Smash 'N' Splash 5, and placed second in another, Frostbite 2019.

MkLeo opened the second half of 2019 with a second-place finish at Smash Factor 8, held in Mexico, falling to Tyler "Marss" Martins.

Shortly after, MkLeo won Evo 2019, the largest tournament by number of entrants in the Smash Bros. franchise's history (excluding online tournaments).

After losing in the round of 16 to Takuto "Kameme" Ono, MkLeo defeated a number of other elite players in the losers' bracket and reached the tournament's grand finals, where he defeated Gavin "Tweek" Dempsey twice – first to reset the bracket, and then to win the tournament, and with it a grand prize of over $21,000.

In addition to Evo, he won two other premier tournaments – Super Smash Con 2019 and 2GG: Kongo Saga – and placed second at the major tournaments Shine 2019 and Mainstage 2019.

His high placings in these events secured him a second term as the best Ultimate player in the world in the bi-annual Panda Global rankings.

In January 2020, MkLeo placed second at Genesis 7, again falling to Marss, who deprived MkLeo of a fourth straight Genesis title.

On February 21, just prior to Frostbite 2020, he announced on Twitter that he had departed Echo Fox.
