Flash (フラッシュ) is a retired professional Melee player from Japan, who plays what is considered to be the best Sheik in the country. He is also considered to be one of the top 5 players in Japan, and frequently wins many Japanese tournaments, taking sets off of top players such as So-ten, Gucci, and aMSa in bracket.
In November 2014, Flash traveled to Oakland, California to compete at Do You Fox Wit It?, an Apex 2015 qualifier. In his North American debut, Flash defeated Dr. Z and Azusa in pools. After finishing as the 3rd seed in his pool behind SFAT and Westballz and placing in bracket, he proceeded to defeat MacD before losing to a close 2-1 set to Lord. He then eliminated NMW before being eliminated by Colbol for 13th place.
During his stay in Northern California, Flash attended two of NorCal's weekly tournaments, Get Smashed At the Foundry 24 and 25. At his first appearance in the local, Flash defeated Alan, Laudandus, and Toph, but was swiftly double-eliminated by Shroomed, rounding up to 3rd place. However, in his second appearance, Flash made a series of upsets by defeating HomeMadeWaffles, SFAT, Silent Wolf, and Silent Wolf once more in Grand Finals, finishing in first place. Along with Nintendude, PPMD, and Leffen he is one of the four out-of-state players to ever win a Get Smashed At the Foundry tournament with a Top 3 NorCal player in attendance.
He retired from competitive play in early 2015. Flash was included on the 2015 SSBMRank list of "hidden bosses".
