Captain Keeta, also called Skull Keeta, and dubbed Lord Keeta by fans, was the leader of the Ikana army.
In The Legend of Zelda: Majora's Mask, Keeta can be found crumpled in a heap underneath a bridge at the back of Ikana Graveyard. If you play the Sonata of Awakening, he will get to his feet, shattering the bridge. He then starts walking down the Path behind the bridge. Link must reach him before he gets to the end of the path. This isnt easy, because Stalchilds pop up and create walls of fire and must be beaten to get through. Once you reach him, hit his legs with your sword and he will turn and fight.
Keeta will run towards you and swat at you with his right hand. Shooting an arrow at him will stun him and allow you to hit him for damage. after awhile, he will jump and attempt to crush you. Avoid this and keep hitting his legs until he admits defeat.
