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.
InuYasha is ranked at 8th on the tier list. InuYasha's sword gives him disjoints and he himself is fast with very quick damage racking ability. This allows InuYasha to overwhelm opponents extremely easily, which when coupled with his high power, leads to an extremely devastating character on the ground, and forces the opponent to rely on projectiles and instakills.
InuYasha is not without flaws, and his most glaring flaw is he struggles against projectile characters. Also, InuYasha struggles to deal with opponents who can outrange him or hit him from afar, leaving bad matchups with the Top 3 characters, and leading his effectiveness to be hampered by characters who benefit the most from recent discoveries. Regardless, InuYasha holds a lot of power, which ranks him in the high tier.
