Evil Ryu (Japanese: 殺意の波動に目覚めたリュウ | Hepburn: Satsui no Hadō ni Mezameta Ryū, "Ryu with the Surge of Killing Intent Awakened", also known as Satsui Ryu (殺意リュウ, Satsui Ryū, literally known as Killing Intent Ryu | or Dark Ryu) is a character from the Street Fighter series who was originally featured in the 1996 Street Fighter Zero manga before appearing as a playable fighter in Street Fighter Alpha 2. This is the form Ryu takes if he ever succumbs to the Satsui no Hado. Ryu ultimately purged his evil half when he overcame the Satsui no Hado, but doing so briefly gave birth to a powerful new foe.
