Angel is a white Siberian cat ghost. He is shy and aggressive, but he also has a soft side. Angel is seeking revenge against the person who killed him, but all he can remember about the dog was that he has a deep voice and told him "Hello puppy..." Angel is only fond of one person, his sister, a black Bombay cat named Coco.
Angel has special abilities as a ghost, being able to claw at you despite being spectral, and he can open his mouth freakishly wide to chomp your head off.
