Giant Sea Creature

A giant cybernetic Brachiosaurus-like monster that emerged from the seas after it was called by Moltor to attack after losing Andrew to the Rangers. Though it was defeated by the DriveMax Megazord, Moltor activated the monster's self-destruct to blow up the Megazord and kill the Rangers, who then managed to have the DriveMax Megazord kick the monster away before it blew up.
