Furmanite
- Furmanite is a substance from the Beast Wars portion of the Generation 1 continuity family.

Furmanite, or anti-energon, is a substance that repels energon at low doses. In higher quantities, it can cause planet-shattering explosions if it comes in contact with energon. Furmanite can be infused into a Transformer's infrastructure to create energon armor.
Fiction
3H comics
Seeking to discover a way to safeguard against energon overload while in robot mode, Fractyl developed a substance he called furmanite on prehistoric Earth. After Fractyl successfully tested its energon-shielding properties, Packrat stole the furmanite; in the chaos, it was discovered to be anti-energon when shards of furmanite explosively reacted with pure energon.
The furmanite was infused into Packrat's structure, and he threatened the planet by travelling into the Badlands, an energon-rich area. Despite some reluctance and arrogance, Packrat allowed the furmanite to be siphoned from his body when he was convinced by Rhinox to do so. Ground Zero
Notes
- The name is an obvious reference to Simon Furman.
