Zero is a long-serving member of the Renegade cause. Predating even Cy-Kill, the arrogant Zero sees the Renegade commander as a late-comer, and often thinks little enough of his leadership to challenge Cy-Kill. He has led direct uprisings against his rival, or other times worked in secret to undermine him from within.
Challenge of the GoBots cartoon
From Axiom Nexus Cy-Kill, perhaps deliberately, misremembered Zero as showing him mercy during the Battle of Parthus when Cy-Kill was still a Guardian "stooge". He also cited Zero as an example of the GoBots' more impressive variety of alternate modes than most Cybertronians. Cy-Kill recalled the events of Zero's treachery to his audience, and remarked on how the Lord High GoBot of Level 17, Gunnyr, proved a suitable replacement for the subcommander vacancy in his hierarchy.
In an alternate reality, Cy-Kill's Renegades had conquered the Guardians and ruled both Earth and Gobotron. Zero controlled Earth as Cy-kill's viceroy, although this did mean he had to tolerate their long-time collaborate, Zebediah Braxis.
Back in the main timeline, Zero and the Master Renegade met up at a bar in the Beta Leonis system while independently on the run from Cy-Kill. They formed a mutually beneficial alliance against Guardians and Renegades alike. Zero and the Master Renegade raided a global summit on pollution and made off with a plastic-eating algae that the Master was able to augment into a super-algae. On Gobotron, they used the super-algae to immobilize Zeemon's Guardian Council as well as Leader-1's team when they tried to intervene.
Now in control of Gobotron, Zero turned on the Master Renegade and incapacitated him in the algae next to the Guardians. Unfortunately for Zero, the Master Renegade told Leader-1 how to disable the algae, and soon the Guardian commander was free, chasing Zero through space as he desperately tried to escape. Instead, he flew right into Cy-Kill and his cloaked Thruster. Leader-1 gladly left Zero to Cy-Kill's tender mercies, and Zero was carted away by the Renegades to face their unique brand of justice.
Ask Vector Prime
While discussing a Quadwal universe where GoBots surpassed Transformers as the dominant converting robot franchise, Vector Prime mentioned the Reign of Zero comic series, published by IDW as a companion to Michael Bay's GoBots movies.
"Echoes and Fragments"
Sideways and Gong attempted to have some fun by mingling the universal streams of a GoBots reality with those of a Transformers reality during the events leading to their first encounter with Unicron. As a result, Zero often found himself playing out a role previously reserved for the treacherous Decepticon second-in-command, Starscream.
When Optimus Prime prepared to make a special run to Autobot City on Earth, Zero was present with the Renegades when Snoop returned from her spy mission with the information. Cy-Kill tossed a thinly-veiled insult at Zero while congratulating Snoop on her effectiveness.
The Renegades intercepted the Autobot Command Center on its way to Autobot City. Zero led the Renegades as subcommander during their brief but furious battle with Brawn, Ironhide, Prowl, and Ratchet. When Cy-Kill crooned about how easy the hijacking was, Zero shot back that Moonbase One was a true target of value. Cy-Kill waved off his lieutenant, however, focused on the prize of Autobot City once they slipped by their defenses.
The Command Center failed to penetrate security undetected, however. Hot Rod and Nick Burns spotted Zero through the hole the Renegades blew in the shuttle, forcing the invaders to abandon ship before reaching the city. Zero tried to gun down Springer and Arcee before they transformed Autobot City into fortress mode, but ended up having to shoot his own foot when he got caught in the folding and reconfiguring components.
After a few more reality-shifts caused by Sideways and Gong, Zero was second-in-command to Megatron in a combined Decepticon and Renegade army. As the villains were driven into retreat aboard Astrotrain, Zero took the opportunity to dispose of the seriously injured Megatron. He tossed his leader and the other injured soldiers out of the ship, and declared himself the new leader of the Decepticons. A number of objections arose from Tank, Snoop, Dr. Go and the Puzzlers, but Zero eventually came out on top.
At his coronation ceremony in the Renegade Hall of Heroes, Zero was crowned the new leader only seconds before being interrupted by the arrival of Galvatron. Shocked and confused by Galvatron's resemblance to Megatron, Zero didn't react when the newcomer converted to cannon mode and blasted him into ash.
