Oxidium is a fast acting rusting agent found on the planet Scylla.


After escaping in the mass Breakout, the villain Jawblade headed to Scylla with the plan of collecting enough Oxidium to rust any Hero's armor and did so with William Furno. However, Furno supercharged his Hero Core and undid the effects, then captured Jawblade. This proves it is uneffective for Heroes.
