B.T. (ビーティー Bītī) is the protagonist of Cool Shock B.T., as well as its one-shot chapter before serialization, B.T. "The Wicked Boy".
He is a clever yet quite malicious boy who befriends Koichi Mugikari at the beginning of the story. With his smarts, B.T. fights against all manners of bullies but also commits his own crimes.
B.T. makes a return in the spin-off one-shot Cool Shock Old B.T., which is set sixty years after the original series.
