BIg Slammu is the sports-oriented brother and the strongest (as well as youngest) of the four. He is also a football player in high school. In the first episode, he uses a skateboard to get around. When he is transformed into Big Slammu, he becomes a whale shark (which was depicted as a carnivorous shark in this franchise instead of a filter-feeding shark). His most prominently featured attack is called "Seismic Slam" where Slammu sets off an earthquake by hitting the ground with his fists.
