Rex

Half machine and half nightmare, this monster is a giant dragon head of maroon armor with rows of ivory fangs that snap shut on anything foolish enough to drift close. Salmon and cream thruster blocks stack behind its skull like a crown of engines, and a heavy cannon juts out beside its jaw. Thick white smoke curls between its teeth when it growls.

That smoke is a warning. The furnace inside is already burning.

Rex rides with the Ziefin, and the raiders treat it like a prized pet. The soul inside was a dockworker known for his temper and his loud, booming laugh. He Upleveled after losing a bet to a Ziefin captain, and he has been laughing, roaring and biting ever since.

Its signature attack is the Furnace Bite, built on its massive attack and special attack. The jaws clamp down, the cannon fires at point blank range, and a blast of fire pours from its throat at once.
