- Graviton (Hellflame Mini-Con, 2005)
- A retool of the Armada Emergency Mini-Con Team member Firebot, Graviton transforms into both a crash-response truck and a (non-firing) multi-missile rack, with an added 5mm peg unique to this release so he could be used as a hand-held weapon. He was only available at Japanese Jusco stores in March of 2005 with the purchase of the Scourge toy.
- Graviton white version (Mini-Con, 2005)
- An all-white version of the Hellflame Team was also released in March 2005 as a Jusco store exclusive; white Graviton was available with the purchase of the small die-cast "HSB" version of Galaxy Force Optimus Prime.
