Bobcat was one of Gaia’s hakkenshi of darkness.
Bobcat is a Hokkaido Wolf with presumably white fur.
He has black spots on his face and black stripes on his back and tail. He also has black markings around his eyes and dash of dark fur on his muzzle.
In Meteor Gin, he is described as looking unusual for a wolf.
Ginga: Nagareboshi Gin
He was trained by Juga to be a hakkenshi of Sirius. Just like the other hakkenshi of Gaia, he believed he was a true hakkenshi.
He awaits Gin's groups arrival with Blacksnake. He never fights and his technique isn't seen because Juga interrupts the fight between the two groups before it's his turn.
When he tries to stop Gin from following Juga, he is knocked aside and eventually defeated by Raiga, Sakon and Ukon.
He is not seen again after this and likely died during the earthquake which destroyed the Underworld.
