Hitodanger

Hitodanger (ヒトデンジャー) - A giant starfish monster. Had strength far surpassing a human being and could launch himself into his opponents. His personal emblem, worn on his soldiers' masks, was a starfish. The symbol spread around his base was a white bird statue with a red starfish above their heads. Hitodanger protected a secret Shocker base which prepared missile launchers, killing anyone who approached it. However, a boy escaped and was found by Hayato. Eventually, he was forced to fight against Kamen Rider #2 in a shallow river. Destroyed by falling underneath a waterfall.
