Chestbeater

The three Chestbeaters are the first boss encountered in Golden sun: The Lost Age. They are fought at the end of the trial in the Kandorean Temple, as the final challenge before earning the lash pebble. They each have 155 hp, and are weak against Mars Psyenergy.

in battle, they use mainly physical attacks and resemble black-furred gorrillas with blue faces, hands and feet. When fighting them do not forget to heal, as they deal quite a large ammount of damage relative to the time you meet them.
