Ninja Gaiden series (1988-1992) Ryu Hayabusa makes his official debut in the original
Ninja Gaiden arcade game released in 1988. He is given a backstory of searching for his missing father who had disappeared to partake in a life-or-death fight. Ken had instructed Ryu in a letter beforehand to travel to the United States to find his friend Dr. Walter Smith, but Ryu encounters Bloody Malth, who had defeated Ken in battle and then subjected him to a
brainwashing that causes him to attack his own son, a spell that Ryu manages to break. However, Ken is slain by Malth's superior, an evil sorcerer known as the Jaquio, whom Ryu then kills. Ryu later enters into a relationship with
CIA agent Irene Lew. In
Ninja Gaiden II: The Dark Sword of Chaos (1990), Ryu foils the Jaquio's demonic master Ashtar's attempt at world domination. In retaliation, Ashtar kidnaps Irene in order to lure Ryu to his home dimension. Ryu defeats Ashtar a second time, but before he can rescue Irene, she is then captured by the Jaquio, who now bears the Dark Sword, the antithesis to Ryu's signature "Dragon Sword" weapon. Having then been killed by Ryu once again, the Jaquio is revived by his blood flowing into his sword, with which he stabs Irene. Her own blood further empowers his sword and conjures a creature known as the Demon; Ryu kills it and Jaquio's Dark Sword is destroyed in the process, but Irene dies from her wounds. She is then brought back to life by ancestral powers flowing through Ryu's Dragon Sword. 1991's
Ninja Gaiden III: The Ancient Ship of Doom sees Ryu accused of murdering Irene, but she actually survives the attack, while the culprit is revealed to be a superhuman clone of Ryu called a "Bio-Noid", created by Irene's superior and corrupt CIA director, Foster. After Ryu defeats the double, Foster is killed by H.P. Clancy, who had instructed Ryu to locate a ruin called the "Castle Rock Fortress", which was the base of Foster's Bio-Noid experimentation and has also secretly housed an interdimensional warship that Clancy intends to use for global dominance. Ryu kills Clancy in battle and the ship is destroyed as Ryu escapes with Irene, bringing the first-generation
Ninja Gaiden storyline to a close. The 1991
Game Gear version of
Ninja Gaiden scraps the entire narrative of the original series timeline, where someone is trying to steal his dragon sword. He travels to four parts of the world to defeat the demon Shiragane and prevent
World War III from starting. The 1992
Master System version of
Ninja Gaiden also eludes the original series timeline, featuring Ryu as a high-ranking member of his ninja clan whose village is massacred while an artifact called the "Sacred Scroll of
Bushido" has been stolen. His mission is to regain the scroll from the hands of the evil Shogun of Darkness and his minions.
Ninja Gaiden series (2004-present) In
Ninja Gaiden (2004), Ryu obtains the Dragon Sword. While Ryu is visiting his uncle Murai, Hayabusa Village is annihilated in his absence and a sword known as the "Dark Dragon Blade" is stolen by the evil Doku. He is brought back to life by his clan's animal spirit, the falcon, and he searches for the stolen sword while hoping to avenge his clan. He defeats Doku and then his overlord, the Holy Emperor Vigoor, and recovers the blade. In the end, Ryu and his newest accomplice, a fiend-hunter named
Rachel, encounter the mysterious "Dark Disciple", who is actually Ryu's traitorous uncle. After Murai's death, Ryu destroys the sword. The plot of 2008's
Ninja Gaiden: Dragon Sword has Ryu find seven Dark Dragonstones, defeating several bosses along the way. At the climax, Doku's former servant Ishtaros steals the stones and defeats Ryu in battle. However, when Kureha—Momiji's sister and a childhood friend of Ryu from the previous game who had died in the village attack—fuses with an object called the Dragon Eye, the stones transform into the Dragon Sword. Ryu defeats Ishtaros and her sister, frees Momiji and returns her home where they begin training together. In
Ninja Gaiden II (2008), a CIA agent named Sonia warns Ryu of the Greater Fiends, whose queen, Elizébet, attempts to steal an artifact called the Demon Statue, which is hidden in the Hayabusa ninja village and what she desires in order to resurrect the Archfiend Vazdah. After his village is razed once again and the statue is stolen, Ryu infiltrates a castle where the object is held. Joe is critically wounded in his battle against Black Spider clan leader Genshin, who then attempts multiple times to kill Ryu thereafter but fails and is slain in his final attempt despite Elizébet having transformed him into one of the game's sub-bosses, the Four Greater Fiends. Before he dies, Genshin gives Ryu a sword called the "Blade of the Archfiend". Following the demise of the three other Greater Fiends, Ryu kills Elizébet and Vazdah with both the blade and his own Dragon Sword. At the conclusion, he uses the Archfiend's sword to mark Genshin's gravesite in a cemetery located at the summit of
Mount Fuji. Ryu is summoned by the
JSDF in
Ninja Gaiden 3 (2012) to assist with the suppression of a terrorist group called the Lords of Alchemy. He pursues the terrorists and their mysterious leader around the world, but realizes he cannot complete his mission without the Dragon Sword. While stalking the group, he also must save a young girl whom he had promised to protect, named Canna. After he succeeds in terminating the group, he destroys another final boss character bent on global destruction and returns the child safely to her mother before disappearing into the shadows. Ryu's story continues in the 2013 release
Yaiba: Ninja Gaiden Z, in which he is not playable; instead, he is pursued by the game's protagonist, Yaiba Kamikaze, in his quest for revenge after having been wounded by Ryu's Dragon Sword. In
Ninja Gaiden 4, the veteran Ryu Hayabusa serves as a "major challenge and growth milestone" for the protagonist Yakumo, while also being playable throughout the story.
