I think Zazanbo (in Japanese ザザンボ) is the tallest in the whole band at 184cm. That's over 6 feet for you Americans! His "real" name is Sharaku Kobayashi. Real in quotes because I don't believe Sharaku would be his legal name.
He wears a pair of red horns and leaves only one quarter of his face unpainted. He's an interesting guy.
He's also in FLOPPY (with Jumbo Toda) and Metronome, plus he has solo works under his real name and as TECHNO-CATS. He seems to be a very busy guy.
