There's little known about him except him being an older brother of Sumo. He's more of a jerk to his little brother, Sumo and it's unknown if he acts like this to all his other siblings. However, in "Stump Brothers", when his father was trying to put both into a family tradition test (since he is annoyed of Tanner bullying Sumo), by singly hammer the nail on a tree stump, but when he tries, the nail fails to flatten, leaving Sumo to do it as he succeeds. Later in the episode, he and Sumo were angrily enagaged in combat, Sumo tries to state that Tanner is always messing with him. He finally stated that he wanted Sumo to not get soft but instead to get him to toughen up. He summarized that Sumo's friend, Clarence is being too soft on Sumo and not being tough enough.
