Energy Element (エネルギー元素 Enerugī Genso?), also called Energy Crystal (エネルギー結晶 Enerugī Kesshou?), is a type of energy resource from Mega Man 3 needed by Dr. Light and Dr. Wily to be used on the giant peace-keeping robot Gamma. They were scattered about uncharted planets, so the doctors sent robots to mine them. For some reason, these robots suddenly have gone crazy, and Mega Man set out with Rush to stop the robots and retrieve the Energy Elements protected by them. After fighting against Break Man, Dr. Wily steals Gamma and the Energy Elements. The Energy Elements were never shown in the game, and it's unknown what happened to them after Gamma's destruction, presumably being lost or destroyed.
