Bell used to be a hunting dog living with a human.
Ginga Densetsu Weed
His master was killed by the bears who roamed the forest around his home. Afterwards, Bell became a wild dog obsessed with the desire of getting his master's revenge. Like Knuckle, he is also under the command of Liger. Bell meets Kotetsu and Koyuki in the forest and warns them about the bear threat in the area. As they talk, a bear surprises them. He, along with his comrades, tries to follow the bear and gets wounded. With the help of Weed, he is carried back to Weed's brother Joe's owner Ninomiya, for caring. As he gets better, he follows Joe into the forest once more to defeat the bears. In the forest, he enters a fight with the enormous bear, the Hybrid Grizzly Bear. He manages to grip on the bear's neck, but his back gets gored by the bear's claws and dies instantly.
