Atomsk is a SSBU King Dedede and Banjo & Kazooie smasher from New Jersey. He was formerly ranked 7th on the New Jersey Smash Ultimate Power Rankings. Within Ultimate, he has taken sets off of high-caliber players such as Pelca, Sinji, and Gen.
In Brawl, he mostly plays King Dedede, and was perpetually considered to be one of the best King Dedede mains in the world throughout its entire competitive life, at times being considered the absolute best in debate with Coney. But he was also known for playing a large variety of other characters at a high competitive level, including Meta Knight, Wario, Falco, Ice Climbers, Fox, and Wolf. He notably placed 5th in Brawl singles, 3rd in doubles, and 2nd in regional crews at Apex 2009. He has taken sets off of top professional players such as Ally, ADHD, UltimateRazer, MJG, Mr.R, Vinnie, Trela, Fatal, and ANTi. Atomsk was formerly ranked 7th on the New Jersey Smash 4 Power Rankings, 10th on the Tristate Brawl Power Rankings, and 13th on the 2016-2017 SSBBRank.
Unlike many other renowned Brawl players, Atomsk did not fully move on to Smash 4 after the demise of Brawl's competitive scene, with his Smash 4 tournament activity being scarce and his ability in it being at a significantly lower level. Instead Atomsk focused on Melee, including travelling to GENESIS 4 to enter only Melee.
Atomsk was signed by ATK Mode on July 17th, 2019.
