Jawbreaker belongs to a race of robots who manage and maintain a vast underground complex filled with enormous machines that operate the legendary Sky Train,
which connects a thousand different islands every day. Like many other bots, Jawbreaker led a very organized life of rules and guidelines, and that suited him just fine. Until the day when an army of Gear Trolls invades the complex.
Great railway enthusiasts, they intended to seize the Sky Train to use it for their own evil purposes. Jawbreaker rushed in front of them and thrashed the Trolls so much that they retreated.
His ability to react impulsively and appropriately allowed him to join the Trap Team, where his Traptanium fists come in handy against the forces of evil!
