A dark, corrupted version of Ryu from the Street Fighter series, awakened to the power of the Satsui no Hado, a violent killing intent that threatens to consume him. This form represents his struggle between discipline and inner darkness, making him a major symbolic rival to his own ideals and to fighters like Ken and Akuma. He appears as a powerful alternate incarnation or state rather than a separate person, emphasizing the central theme of self-control versus destructive power.
