Liger is a mix breed, who was a hunting dog. His owner was killed by the Hybrid Grizzly Bear and he became a wild dog obsessed with the idea of avenging his owner. He leads four other dogs.

He met Kotetsu and Koyuki in the forest, warning them about the bears when one of them shows up and wounds Liger in the head. Thanks to Weed, he gets carried to Joe's owner, Ninomya, where he gets better and heals. After that, he follows Joe in the forest and they fight against the Hybrid Grizzly Bear. Liger throws himself in front of Joe, to protects him, but he gets caught into the bear's jaws and gets killed.
