Ninja Gaiden / Dead or Alive · Protagonist · Debut: 1988 · Arcade / NES · Created by Hideo Yoshizawa (designed by Masato Kato)
Tecmo's dragon-lineage ninja debuted in Ninja Gaiden in 1988, joined Dead or Alive in 1996, and was reinvented in Team Ninja's 3D Ninja Gaiden of 2004.
Ryu Hayabusa first appeared in 1988 in Tecmo's Ninja Gaiden, which was released in different forms in arcades and on the NES. He was created by Hideo Yoshizawa, who has said he was influenced by several Castlevania games, and designed by Masato Kato. Ryu is a descendant of a dragon lineage, the leader of the Hayabusa ninja clan, and wields the clan's ancestral Dragon Sword. The NES game made him famous. Its story begins with Ryu setting out after receiving a letter from his father, Ken Hayabusa, and was told through extensive cinematic cut-scenes between stages — unusual for an action game of the time. Combined with the game's fast, demanding wall-jumping action, it made Ryu one of the defining action heroes of the 8-bit era. Ryu later crossed into Tecmo's fighting series, appearing in the original Dead or Alive in 1996 — a role that had initially been planned for a different character named Kamui. In 2004 Tomonobu Itagaki and Team Ninja relaunched Ninja Gaiden as a 3D action game, reimagining Ryu's appearance for a modern audience while keeping his core character, and the new game became known as one of the most demanding action games of its generation.
Ninja Gaiden on the NES framed its stages with cinematic scenes that told a full revenge story. It was an early demonstration that an action game could carry a plot, and much of Ryu's identity as a character came from those scenes rather than from the action itself.
