Wilson in GNGEdit
Wilson used to be a circus dog in Shikoku. His owner, Hiroshe, caught Kurojaki in the wild and used him as a circus dog for a while. One day, Kurojaki went crazy and killed Londo, Wilson's son. Kurojaki then kidnapped Wilson's mate Lean, whom Wilson later found the skeleton of in a cave. She had been eaten by the Koga dogs.
He wanted revenge and kidnapped Kurojaki's son Chibi, who he throws out from a cliff. Kurojaki gets furious and pushed Wilson out from the cliff too. When Cross tries to save the puppy, she too falls. However they survive the fall and Wilson joins Ben’s platoon.
After the final battle, Wilson comes Gin to aid, when he is fighting the wolf Juga in the Underworld.
