The Fission Lance was a radioactive melee weapon created by Vox Industries and modeled off of Gadgetron's Omniwrench 12000. It was identical in appearance to the Versa-Wrench models, except the head of the Fission Lance was set on fire. It was an upgrade to the Versa-Wrench Striker, featuring enhanced attack power. This wrench could be purchased from any Vox Industries weapon vendor for 32,000 bolts.

Later while competing in Dreadzone, Ratchet replaced this wrench with the Obsidian Blade.
