The Obsidian Blade V2 was an illegal upgrade to the already highly illegal Obsidian Blade. This upgrade ran a 2.9 gigavolt differential across the wrench's core to superheat the striking face and thus boosted striking power significantly. This wrench was available after the Avenger Tournament for 60,000 bolts in Challenge Mode.
Through in-game unlockable cheat, "Super Morphing Freeze Wrench", the wrench could Freeze enemies and Morph them into farm animals when defeated.
Its appearance is almost identical to the OmniWrench 12000, but set on fire.
- Like the Obsidian Eye, it may have been made of Obsidian.
- Ratchet: Deadlocked (first appearance)
