His origins are currently unknown, as he was found by Monty (a fat rat mechanic) in a junkyard/dump as a canid-like anthro barely holding on to dear life, the damages to his body horrendous as if he was ripped apart. Soon after, Monty took him to his repair shop to fix him up as best he could, as the nearest hospital was miles away. With the many parts he had, Monty was able to revitalize him with biomechanics/cybermic, resulting in the behemoth, Mons! Short for “Monster the Truck”, yet called “Mons” to make him sound more kindhearted and less feared than his full name. Even with his terrifying height and looks, he’s mostly a sweet, greedy gut kind of protogen like beast, mostly helping out in the auto shop, even if he can be pretty clumsy with his size.

He can also help out his master in the ring as a “tag team like duo”, Monto riding around inside Mons (a separate compartment) and “driving” him into the ring, as the duo that brings fear from the junkyard, “The Trash Compactor and Monster the Truck!” As a side note, Mons is powered by food, biodiesel, and even prey that he can churn up into biodiesel. Monty can make sure he watches his eating habits while in the ring.
