Name: BamBamMan Age: 25 Personality: Clumsy, yet occasionally charismatic Appearance: A head made of a bomb (not spiky hair, but an actual bomb), sharp eyes, and a fuse that is always burning. Outfit: A blue suit with orange limbs and an orange 'B' logo, plus an orange cape. Weapon: Water gun, bombs The leader of the BamBam Legion, he is very agile and highly intelligent. His goal is to raise the Earth's temperature to 100 degrees and make it explode. He thought it would be easy... but he often fails due to Kai, Marin, and the Water Rangers, revealing a clumsy side (which is secretly cute!). Unlike his appearance suggests, he has slightly sharp fangs. (It might hurt if he bites!) He cares for his BamBam Legion. Though he looks at them with pathetic eyes when they mess up or fail, he is a tsundere who ultimately looks after them. He doesn't use profanity, but he is very good at teasing others. (Even that behavior is adorable.)
