Big Slammu

Coop "Big Slammu" Bolton is the sport-oriented brother, and the strongest (as well as youngest) of the four. He was also a football player in high school. In the first episode, he uses a skateboard to get around. When he transforms into Slammu, he becomes a Whale Shark. His most prominently featured attack is called "Seismic Slam", where Slammu sets off an earthquake by hitting the ground with his fists.
