Elm Gigas is an enemy fought in the Game Boy Advance and later remakes of the game at Hellfire Chasm and Whisperwind Cove. Despite appearing much later than the Hill Gigas, they are of no threat to the player.
Elm Gigas is an enemy fought around the Library of the Ancients in the Merged World, using Left Jab and Aeroga to attack the player. It is a semi-strong enemy when first fought, but is otherwise not a difficult foe to deal with.
