The Praetorian OmniWrench was a powerful wrench-type used as by members of the Lombax Praetorian Guard. It was a double-ended wrench powered by negatively-charged energy, which it could release in the form of projectiles, beams or shockwaves. When in use, its length was extendable and when not in use it could be worn on the user's back. Alister Azimuth, a famed Lombax Elder and Four-Bolt Magistrate of the Praetorian Guard, was known to carry this type of OmniWrench. It later fell into the possession of Ratchet after its former master died to save the Great Clock, and effectively the universe from total destruction.
