Kraid

Kraid is a dinosaur-like alien, that's a recurring enemy in Metroid. He first appeared in Metroid for the NES, and has reappeared in most of the Metroid games every since.

Kraid fights with razor sharp claws and shoots out t-rx-like arms out of his stomach. His weakness is his third eye. When Samus shoots at the eye, Kraid's mouth opens for a second. Samus then shoots Kraid in the mouth, injuring Kraid. She does this several times until Kraid is defeated.
