Siberius was an icy planet which was home to the Frozen Base used by the Unknown Thief, and was the location where the thief tried to destroy the Protopet. The thief was foiled by Ratchet, who retrieved the Protopet and returned it to Abercrombie Fizzwidget. The planet was similar to Hoven and the water on Siberius was also similar to the water on Hoven and Grelbin. Ratchet would freeze if he touched it. Siberius was located in the Bogon Galaxy.
The planet appeared in the Secret Agent Clank movie premiere, Clank hoverboarded through the icy wastes chased by two Ninja Bots, and defeats Maximillian with Skrunch's help.

- A way to save on ammo when an enemy comes was to shoot an icicle when the enemy was underneath it. One good way was using the Lancer to conserve the ammo of other weapons. The icicle didn't have to be at a certain height as long as the enemy was underneath it, the enemy would be killed.
