InuYasha (incorrectly romanized as Inuyasha in Super Smash Flash) is an unlockable character in SSF. He is unlocked by clearing Adventure mode on any difficulty with any character without losing any lives. He wields a sword named the Tessaiga (鉄砕牙, "Iron-Crushing Fang") that he uses along with his Hijin Kessō and Sankon Tessō. He is the only character representation of the InuYasha universe.
