'''Leon''' is a French ''[[Ultimate]]'' {{SSBU|Lucina}} player with a {{SSBU|Roy}} secondary from Vitry-sur-Seine, Greater Paris Area, who is currently one of the best Lucina players in the world, along with {{Sm|Mr. E}}, one of the best Roy players in Europe, and one of the best smashers in France. 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 {{Sm|Glutonny}}, {{Sm|Riddles}}, {{Sm|Fatality}}, {{Sm|Scend}}, Mr. E, {{Sm|Charliedaking}}, {{Sm|Flow|p=France}}, and {{Sm|Oryon}} and is currently ranked 10th on the [[OrionRank 2022/Europe|OrionRank 2022 Europe]], 7th on the [[European Ultimate Power Rankings]], and 89th on the [[LumiRank 2023]]. 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 {{SSBM|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 {{SSBB|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 {{Sm|Glutonny}}, who three-stocked him in WF at [[Bushido Impact#8th_Impact|Bushido Impact 8th Impact]], Glutonny's first tournament. As time passed by, he progressively started to play {{SSBB|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 [http://youtu.be/rBIAN1OaSHk?t=3m11s here]. Leon frequently attended major tournaments in North America, such as {{b|SKTAR|tournament}} and the {{b|Apex|tournament series}} tournament series, where he has achieved significant placings. He has taken sets off of top players such as {{Sm|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 {{forwiiu}}, Leon gave the game a chance upon its release, playing {{SSB4|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.
