Shuriken was once a human named, Akio, who lived in Japan on planet Earth, where he was working on a rice farm with his father, however when the Earth Defense Initiative visited their house and asked his father to have his son "work with them or die", Akio's father denied their request and he was shot to death by soldiers. Akio escaped Earth and joined Blaze and his friends so that he can have revenge on Frederick. He was turned into a pony so and rennamed himself to "Shuriken the Bat Pony" so that Frederick won't know his true identity until the day he has a chance to kill Frederick.
