Ryu Hayabusa's Doppelgänger

Ryu Hayabusa's Doppelgänger is the third antagonist in Ninja Gaiden III: the Ancient of Doom next to Foster and HP Clancy.

Story
Ex-CIA agent Irene Lew was investigating a mysterious laboratory. During her mission, she was killed by a figure resembling her ally Ryu Hayabusa. Ryu was accused of the murder and decided to search for answers. During Ryu's investigation, he encountered the being who framed him. Both of them engaged in a sword duel but Ryu quickly lost. The person claimed to be Ryu's clone. He also admitted responsibility for Irene Lew's death. According to the clone, he was ordered by Foster to let Ryu live longer. He then left Ryu who was still confused. Later, Ryu encountered Foster at a place called the Castle-Rock Fortress. Foster was about to order the clone to attack Ryu. Suddenly, Irene appeared after claiming to survive the attack. Ryu's clone transformed into a powerful monster and threatened to kill her and the real Ryu. Irene attempted to use her gun, but it was useless. Ryu killed his clone in a battle. When Ryu pursued Clancy into subspace, he encountered his clone again. The subspace energy mutated Ryu's clone into a much more powerful form. He was destroyed by Ryu and remained dead.

Appearance
Ryu Hayabusa's Doppelgänger possesses three forms. His first form is identical to the original except his hair is slightly longer and is cropped. In his second form, he is a tall monster with dark blue skin and dark red eyes. He is a large beast with red eyes and dark yellow skin in his final form.

Personality
The Doppelgänger is the exact opposite of Ryu Hayabusa. It is cynical, violent, and takes pleasure in the harm of others' misfortunes. Unlike the real Ryu, the Doppelgänger has no sense of honor. Instead, he has a blood lust. Despite his violent demeanor, he is still loyal to his superiors and always follows the orders regardless of his personal desires.
