Meltdown despises war but wouldn't dream of leaving a fellow Autobot behind to face it alone. His specialty is using beam weapons for repair or, if absolutely necessary, combat. It is rumored that he cares "too much" and has some emotional issues with combat, even closing his eyes rather than watching his missiles hit a living target. Still, those issues aside he is the best kind of health insurance to have on a battlefield. An Autobot "Guardian," he is designed to absorb massive amounts of damage and outfitted with everything needed to repair himself and other robots around him. Meltdown is all about controlling the battlefield and in addition to his durability and repair capabilities he can also paralyze and repel opponents.
His alt-mode is a Multipurpose utility vehicle.
