The giant ice monster defender of Urgon's Machine Part, the ice guardian was a larger four-legged version of the littler, bipedal ice monster minions. It was created by Urgon.
This ice monster was capable of standing on its hind legs, climbing up walls and ceilings, and spitting out sharp icicles at intruders. It was also capable of attacks at close range but is most notorious for rolling into a destructive ball that could crush anyone in its path.
Death of the ice guardian
Although it was successful on some intruders, the ice monster met its match in Indiana Jones. The adventurer retrieved Urgon's part of the Infernal Machine from Urgon's study and used the device's concussive power to injure the monster, smashing its icy body full of cracks. The third time Jones activated the device, the ice guardian exploded into countless tiny pieces.
