The Plot: Optimus Prime battles Serpentor, who suffers confusing bouts of pain from the back of his neck. Meanwhile, Hot Rod leads a combined Autobot/G.I. Joe assault on Serpentor's fortress. Inside, Hawk, Grimlock, and the rest search for Optimus Prime. Elsewhere, Optimus is defeated by Serpentor's right-hand men, Motormaster and Razorclaw. Serpentor opens the Matrix of Leadership within Prime.

Outside, the battle continues while within, Serpentor is transformed into a full-size Decepticon -- but the Matrix has seemingly changed him, removing his warlike nature -- until his body is remotely hijacked by Cobra Commander from Earth. Hawk and company burst in and attack, and Hawk grabs the Matrix after Arcee rips off Serpentor's chestplate. Serpentor is deactivated while, outside, the Autobots and Joes rout the Decepticons. On Earth, Cobra Commander is rendered apparently catatonic.

Later, peace has returned to Cybertron. The Autobots mourn Bumblebee while Hawk comes to terms with his new Matrix-enhanced consciousness.

Continuity Notes: The pain from Serpentor's neck comes from a device planted there by Zartan in issue 1, which subsequently allows Cobra Commander to take control of the robot.

The final page gives us glimpses of threats yet to come, including Doctor Mindbender and Cobra-La, the villains of the next mini-series, as well as latter day Joe characters Sergeant Savage and Iron Klaw, plus city-scale Transformers Trypticon and Metroplex, hinting at a possible fifth series which was likely aborted by Devil's Due losing the G.I. Joe license.

The Plot: Optimus Prime drives around, rescuing Autobots during the Decepticon assualt, until he's cornered by Menasor and Reflector, who put Prime in communication with Serpentor. Prime agrees to surrender to the Decepticons if Serpentor releases his captives. Meanwhile, on Earth, Cobra Commander and his science advisor, Doctor Knox, are up to something.

Serpentor has a chat with Hawk on the nature of war and needing something to fight for, then Snake-Eyes and Scarlett break free of their cell and bust out Hawk and Roadblock as well. Meanwhile, Hot Rod rallies the Autobots to invade Serpentor's headquarters and rescue their friends. Inside, Optimus Prime is brought before Serpentor, but quickly breaks free and attacks the diminutive warlord. On Earth, the assembled G.I. Joe team prepares to travel to Cybertron and join the fight.

Continuity Notes: Cobra Commander at one point refers to "Mindbender and his lobster-wearing friends." This is presumably a reference to Cobra-La, who captured Mindbender at the conclusion of the previous mini-series, and it seems to imply that Cobra is aware of Cobra-La's existence, at least to some extent.

Ratchet is seen among Hot Rod's team still sporting the modifications he acquired during his two years fighting in Earth's future in G.I. JOE VS. THE TRANSFORMERS II.

Storm Shadow is seen among the assembled Joes on the final page, implying he's switched sides since the events of the first mini-series.

The Plot: After receiving a briefing on Serpentor from the scientists who created him, G.I. Joe (Hawk, Roadblock, Scarlett, and Snake-Eyes) and the Autobots (Perceptor, Bumblebee, Arcee, and Grimlock) follow him to Cybertron, where they soon come into conflict with Predaking, Pirahnacon, and Serpentor himself. Serpentor kills Bumblebee and the rest of the group is taken captive.

Elsewhere, as the Autobots prepare for a peace celebration, Optimus Prime dispatches Hot Rod to lead a team to track down their missing friends. Meanwhile, more Decepticons are rallied to Serpentor's cause, and soon his Decepticon army attacks the Autobots' party.

Continuity Notes: We're told that "Serpent O.R." is short for "Serpent Organic Robot", named for the serpent which tempted Adam and Eve because the project team was tempted to use Megatron in their construction of the robot. Seems like kind of a stretch, but he had to be named Serpentor somehow, after all.

Snake-Eyes and Scarlett have a tender moment in which he unmasks for her and they share a kiss.

The Plot: On Cybertron, Optimus Prime broods until Hot Rod informs him that the team on Earth has run into trouble from Cobra. Meanwhile, the Joes and Autobots finish off Cobra's forces but realize Bumblebee is missing, having gone below ground in pursuit of Cobra Commander. Grimlock, Arcee, Perceptor, Hawk, Roadblock, Snake-Eyes, and Scarlett head down and stop Cobra Commander from killing Bumblebee.

Serpent O.R. appears and takes out the Joes' mechs, then brings the roof down on everyone in the room. He heads upstairs and activates the portal the Autobots used to reach Earth, departing for Cybertron. Once there, he finds the Seacons and Predacons scuffling, but quickly wins them to his cause.

Continuity Notes: Perceptor is horrified to find that humans have been working with the deactivated Megatron and Soundwave, but Hawk protests that he had no idea about it.

Serpent O.R. refers to himself as "Serpentor", so I'll go ahead and start calling him that going forward. (For the record, Cobra Commander called him Serpentor last issue, but I wasn't sure then if it was intentional or a typo.)

The Plot: At Area 52, a U.S. government research center in the New Mexico desert, scientists work on both deactivated Decepticons and a new robotic lifeform called Serpent O.R. Meanwhile, several levels above, at G.I. Joe headquarters, Perceptor, Bumblebee, Grimlock, and Arcee arrive to assist with deactivation of all Cybertronian technology still on Earth.

Cobra attacks the facility and Cobra Commander activates Serpent O.R., but but it quickly turns on him. Naming itself the son of Megatron, Serpent O.R. downloads the history of Cybertron from Megatron's deactivated head and then declares he will find the Autobot Matrix of Leadership.

Continuity Notes: The human scientists are working on the heads of Megatron and Soundwave, still offline since the first G.I. JOE VS. THE TRANSFORMERS miniseries. Among the scientists is one Doctor Chase, actually Zartan's sister, Zarana, in disguise.

The Autobots are disabling all Cybretronian technology on Earth under orders from Optimus Prime, to ensure the planet remains free of further Transformer influence. This includes the mechs provided to the Joes by the Autobots when they left Earth in volume 1 (and which were briefly seen at the start of volume 2).

G1 References: Among the memories he pulls from Megatron, Serpent O.R. sees Quintessons, Alpha Trion, Optimus Primal, Unicron, and the Matrix. The flashback confirms that this continuity follows the cartoon series' idea that the Quintessons created the Transformers.
