Tall Man (known as Noppo (ノッポ) in the Japanese version) is one of the cowboys seen in the Brown Country saloon. He is the only person to not be afraid of hearing Launch's name. When Launch shows up in her normal form (everybody only knows her as her bad form), he bought her a drink trying to hit on her. When she sneezed and became her bad counterpart, she knocked him out.

Tall Man seems to be a parody of the type of heroes in old westerns.
