The Omniwrench 12000 is a melee weapon presumed to have been created by Gadgetron. It is an upgrade to the previous version, the Omniwrench 10000. In Ratchet & Clank: Going Commando, Ratchet finds this wrench on his second visit to the planet Aranos, where he used it in place of the Omniwrench 10000 for the rest of the game. Ratchet even used this wrench through the entirety of Ratchet & Clank: Up Your Arsenal, and presumably through the beginning of Ratchet: Deadlocked. It was eventually replaced with a Vox Industries model wrench called the Versa-Wrench Lite.
This weapon was presumed to have been designed by Gadgetron as a basic mechanic's tool, but Ratchet repurposed it as a short range melee weapon. It looks much different than the Omniwrench 8000 and 10000, with a primarily orange and brown color palette. The damage output of this wrench is greatly increased.
- This is the last model of wrench Ratchet finds in Ratchet & Clank: Going Commando.
- This wrench's name is never mentioned in any Ratchet & Clank game. 'Omniwrench 12000' is a fan name.
