Shadow the Hedgehog is a character that appears in the Sonic the Hedgehog game series as a secondary character but also has his own game where he is a titular character. Shadow the Hedgehog is an anthropomorphic hedgehog created by Gerald Robotnik with DNA of Black Doom and looks like Sonic the Hedgehog in many ways. Shadow the Hedgehog serves as Sonic's arch-rival, but sometimes he is also Sonic's ally. Shadow the Hedgehog was released by Dr. Eggman after fifty years he spent in stasis and was enlisted in Eggmans plan to conquer the earth. But Shadow regained his memories and continued to protect humanity for the sake of Maria. A fanart Sonic the Hedgehog progress bar for YouTube with Shadow the Hedgehog Running Pixel.
