History
Deprived of Energon after the near destruction of Cybertron and the draining of its natural resources, a tribe of Monsterbots led by Repugnus was trapped in their simple beast modes for many years, eking out a hardscrabble existence in their dying world. One of Repugnus's fellow Monsterbots captured Bumblebee as he journeyed towards the Well of the Allspark. The Monsterbots would have feasted on the Autobot if it was not for the timely arrival Cheetor, who told them of their mission and used the AllSpark to satisfy their hunger. In gratitude, Repugnus' tribe led the duo to the Well's backdoor. Once Cybertron was restored, the Monsterbots rejoiced at the planet's revival.

At some later point, a snobbish Monsterbot named Affluous forced the unusually intelligent Teknicus to build a device segregating those loyal to him (whom he dubbed the "Energon Masters") and those he deemed unworthy. Banished to the wilds beyond the Monsterbot city, Repugnus' tribe had to survive on scraps, lest they die of starvation or get captured for trespassing. The Energon Masters were visited by Bumblebee, who was on a mission to locate one of Windblade's psychic shards, during one of Affluous's energon parties. The Autobot was thrown into their dungeon, along with Teknicus and Energon Masters sufferings from "the shocks", though he was able to break them out using his multiverse energy.

When fleeing a swarm of Injectors, Repugnus' tribe was saved by Grimlock. In gratitude, Repugnus offered his new Dinobot friend some energon and told him of the Monsterbots' societal divide. Morally outraged by what he heard, Grimlock led Repugnus's tribe to the city to overthrow the Energon Masters. Joined by Bumblebee's party moments later, the Autobots destroyed Teknicus's tower. With the Energon Masters transforming into insect mode and Repugnus's tribe transforming into robot mode, equality among the Monsterbots was restored. As for Affluous, he fled the city in dejection upon transforming into his insect mode.

When Decepticon super-soldiers from a universe where the Decepticons won the Great War invaded Cybertron, Hot Rod rallied the Autobots to Cybertron's underworld, where Repugnus' tribe generously offered sanctuary. Monsterbots would later partake in the climatic final showdown between the Cybertronians of their universe and the alternate reality Decepticons, during which Repugnus saved Bumblebee from a super-soldier by feeding off their Energon.
