Energon

 * Doom-Lock (Basic, 2004)
 * A redeco of Cruellock, Doom-Lock transforms into a dinosaur-monster somewhat reminiscent of the American movie version of Godzilla. He came with a small clear-orange hand-pistol and a large clear-orange sword, both of which stored in his tail in dino mode.  These pieces could combine into an “Energy Blade" Ultimate Energon Weapon that can be used by other Transformers toys.  He also came with a clear-organge Decepticon-style energon chip that can be attached to most Energon toys.


 * In Japan, his sword was used to make the "Energy Blade Phantom Night Edition" promotional exclusive energon weapon, plus a pack-in energon weapon with Galvatron General.
