Cowra / Bullman
A chouju sent by Yapool, Cowra soon morphed into the Bullman in order to remain hidden. (of course he was considered a freak) eventually Cowra revealed it's true form and started destroying a town with his horn beams. Until Ultraman Ace arrived, after a long fight Ace defeated Cowra by putting a ring through it's nose,the monster vanished soon after.

Trivia:
