Called the 'ultimate golem' by his creator, Clench the Cogmaster, Gorbash became a member of the Dragon Slayers by default. Unlike most other golems, Gorbash is infused with an extremely powerful soul, giving the war machine the drive to fight and win in combat.

Gorbash is known as 'the Eternal' due to the fact that Clench designed him in such a way that, if Gorbash were to be defeated in combat, it would take little work to revive the war machine.
