This is the first new character revealed for King of Fighters 15 since the reveal of the first trailer that featured Shun'ei, K', Leona, Mai, Kyo and Benimaru.
Of course, this is actually Meitenkun's second appearance in the King of Fighters series as he made his debut in King of Fighters 14.
Along with Shun'ei, Meitenkun has been trained by Tung Fu Rue.
