InuYasha

InuYasha (犬夜叉, InuYasha? also romanized as Inuyasha) is the protagonist in the manga and anime series InuYasha created by Rumiko Takahashi. Inu means dog and Yasha means spirit, therefore InuYasha literally translates to "dog spirit." He appears in Super Smash Flash as an unlockable character, but he didn't return in the sequel Super Smash Flash 2 as a normal character, but he could be playble via the expansion characters.
