Seelkadoom is an imposing and sinister being. His body is black in color, and his appearance is a mix of elements from Sonic the Hedgehog and Shadow the Hedgehog, two of the series' main characters. He has spiky red spines that resemble Sonic's and dark skin that brings out his dark, malevolent aura. His eyes are a brilliant crimson red, with a piercing, menacing glare that reflects his villainous nature. He wears a long, black cloak resembling Shadow's, but with sinister details and red trim. He also wears black gloves and boots with red details. | Anime
