Shadow the Hedgehog

シャドウ・ザ・ヘッジホッグ

Shadow is an artificially created life form designed as a male, anthropomorphic hedgehog. He resembles Sonic in several ways, such as using hover skates to propel himself at extreme speeds that rival Sonic's; however, he distinguishes himself by making greater use of his signature ability to perform Chaos Control with the Chaos Emeralds. He is Sonic's arch-rival and serves as the antithesis of Sonic in all aspects of Shadow's life. The rings attached to his wrists suppress his power.
Shadow vowed to keep his promise to Maria, a girl he befriended on the Space Colony Ark, to give humanity a chance to be happy. He once blamed humanity for Maria's death, but came to realize that Maria wanted the people on Earth to live happy lives.
