Kabao

Mitsuo's another classmates. He is a neighborhood bully. He often picks on Mitsuo, but is a big fan of Pāman, often begging him to make him the next member. (This is similar to Flash Thompson from the Spider-Man series, who often picks on Peter Parker, but idolizes Spider-Man - Parker's superhero identity.) Together with Sabu, he was tricked by a foreign scientist into stealing Mitsuo's Paaman equipment.
