The Giant Centipede Monster, is a giant monster that is half Ultralink and half Centipede. It could be that when the Evil Ultralinks were being launched from the Makino Ship, possibly one of the Ultralinks came in contract with a centipede, and then turned it into a monster. Then it might had entered the ship and then attacked Commander Forge Ferrus, Max McGrath, and Steel. Then the same one ate Forge's left arm and then it might had died when the ship was destroyed. He first appeared in "Earth Under Siege Part Two", which is the Season Finale of Season 1.
