While stranded in the multiversal hub city of Axiom Nexus, Cy-Kill worked to rebuild his power base with new Renegades. Fright Face led a group of Uniend Predacons camped out in the Heap who confronted Cy-Kill during his exploits. Cy-Kill challenged Fright Face to single combat, with the prize of the loser and his subordinates swearing absolute loyalty to the winner. Fright Face agreed, but ultimately was defeated by the Renegade overlord. True to his word, Fright Face made his men into utterly loyal servants of the mighty Cy-Kill. Cy-Kill even used his old Puzzler technology to give the Predacons a combiner form as Monsterous. Fright Face and the others traveled with Cy-Kill back to his home reality when he abandoned Axiom Nexus.
Cy-Kill and his new recruits emerged in the midst of an epic battle between the Guardian fleet and Rogue Star. As Monsterous, Fright Face and his team gleefully tore through the surprised Courageous before turning on the Command Centers. Unfortunately, Leader-1 tricked Cy-Kill into firing a killing shot at him, which he dodged so that it hit Monsterous instead. This respite allowed the Guardians to retreat, but the Renegades had clearly won the day.
Although the Monsterous Renegades began to integrate into the ranks of Cy-Kill's troops, Fright Face himself remained standoff-ish. Cy-Kill was secretly relieved by this development, as he didn't want Monsterous to fall under the sway of the untrustworthy Monster GoBots. So long as they didn't challenge him to a duel (and win), Cy-Kill felt confident in Fright Face's loyalties. Cy-Kill brought Monsterous to an ambush to try and seize a matter transmutation ring, but the surprise appearance of Courageous made it a fair fight, and so the Renegades retreated again.
At the Cape Canaveral Space Center, Fright Face joined Zod, Stallion, and Jig Saw on an infiltration mission to retrieve a quantum supercomputer from a new space probe. Jig Saw's "Apollo" disguise failed, but Fright Face got ahold of General Newcastle and forced Leader-1 to provide the probe. Before the Renegades could secure the probe, however, Zod bit down into it, shocking him with a quantum-powered electrical surge. Suddenly super-intelligent, Fright Face decided to end the mission and bring the changed Zod back to Cy-Kill.
When the Guardians and UNECOM came to Quartex to sign a tri-planet alliance treaty with Boulder's Rock Lords, Cy-Kill and Magmar decided to intervene. Monsterous and Puzzler were pitted against Courageous and the Fossil Lord's Fossilsaurus until Cy-Kill tipped his hand and revealed the Renegade Power Suit Warrior, Nemesis. The forces of good rallied, however, and prepared a counter-strike. Monsterous was diverted into battle with the Action Shock Rocks, leaving Courageous and Fossilsaurus evenly pitted against Nemesis and Puzzler in the rematch.
