28. Coming of the Fuzors - Part 1
With stasis pods down all over the planet, Tigatron and Air Razor are dispatched on a long-term mission to find them. Dinobot has taken advantage of the battle to steal both golden disks, since he now realizes this is probably Earth and Megatron could change the future. Megatron discovers the two new Fuzors (QUICKSTRIKE and SILVERBOLT) who are confused and disoriented and recruits both of them. A fallen and cracked stasis pod is discovered by the Maximals; it contains a spare protoform without a spark. In Pred base Tarantulas (in Blackarachnia&'s body) discovers his lair has been destroyed so he utilizes Megatron&'s equipment to return to now-transmetal body but leaves a psychic "link" between himself and Blackarachnia. The spiders become a scheming "third force." Rhinox begins a secret project.
29. Coming of the Fuzors - Part 2
Megatron and his forces attack but one Fuzor (SILVERBOLT) decides at a pivotal moment that he is a Maximal and switches sides. Megatron and forces still appear to be about to win. Rhinox&'s secret project is at a pivotal point -- he has dangerously amplified his own core consciousness to penetrate transwarp space -- and as a result he is almost flatlined. But he manages to discover what he was looking for and fight his way back in time to set the secret project on autopilot and rejoin the Maximals in their defense. Back at the Pred base, Blackarachnia discovers a hidden secret in Megatron&'s datatrax and manages to conceal it from Tarantulas. In the battle, the Maximals are backed against a wall, about to be defeated, when Optimus Primal dramatically reappears as a Transmetal. He was Rhinox&'s secret project. Megatron and forces defeated and Optimus is welcomed back.

Blackarachnia takes the opportunity to use the energon as a method of severing the psychic hold Tarantulas had on her. Tarantulas decides that the cavern is perfect for his new lair and in a battle with the Maximals gives the impression it is destroyed. Tarantulas begins constructing his secret lair.
31. Maximal, No More
Dinobot decides that Megatron is winning the Beast Wars and concludes to switch sides. He gives Megatron the second Golden Disk, though not without reservations.

32. Other Visits - Part 1
Tigatron and Air Razor discover an alien artifact and accidentally trigger it, signalling the aliens that the planet was not in fact destroyed. Tigatron and Air Razor are captured in a beam and sent to the alien nebula. The aliens send a MetalHunter base to the planet and both Maximals and Predacons face off over it. But a huge Energon surge drops Maximals and Predacons alike.
33. Other Visits - Part 2
With all but the Transmetals and the Fuzors incapacitated by the MetalHunter Base, Megatron uses the Alien Disk to open a door into the base. Optimus and company try and stop him, but are foiled by a huge Energy Web which Tarantulas has manufactured to hold the base in place. To their dismay, Megatron, Tarantulas and Quickstrike enter the base. There Megatron is almost disabled when he interfaces with the alien controls but eventually he gains control of the alien base. He uses it to capture Optimus and tries to destroy Tarantulas who has informed Megatron that he will no longer be under his command but will function as an independent agent. Due to this treachery Tarantulas winds up teaming up with the Maximals to prevent Megatron from transporting the MetalHunter Base back to Cybertron. The effort is successful and not only foils Megatron&'s master plan, BUT also closes the alien wormhole above the planet, rendering it safe from further alien invasion.
34. Bad Spark
The discovery of a strange stasis pod is bad news for Optimus -- it means the secret Protoform X has survived. This attempt to create an immortal Maximal created only a psychopath. In a massive Energon explosion caused by battle over the pod, both Blackarachnia and Silverbolt are plunged into survival circumstances where they are forced to cooperate to survive. And all the while the newly created Rampage (formed by the Protoform X) is stalking them. Rampage is defeated by the Maximals but enslaved by Megatron, who captures the core of his Spark in an Energon cage.
35. Code of Hero
Since Megatron now has the disks and Rampage, he decides to make his move. He decides to prevent the human race from ever occurring by destroying the valley from which they emerged. Dinobot, still wracked with guilt over his giving the disk to Megatron, is the first to discover the plan. With no other Maximals available, Dinobot singlehandedly takes on the Predacon forces in a heroic battle to save the human race. He succeeds, but at the cost of his own life. The Maximals drive off the Preds, the human race is saved, and Dinobot gets the warrior&'s recycling honors he always dreamed of.
36. Transmutate
Another stasis pod is discovered on the outskirts of the Maximal Base, and Megatron and Silverbolt fight over it. In the course of their battle, the pod explodes, and a large, monstrous, vaguely female, form appears. The ‘Transmutate&' is badly formed, but still lashes out at both Megatron and Silverbolt. Megatron eventually captures her, but he cannot get her to transform, so he orders her destroyed. Rampage however, feels that the Transmutate could be valuable, and tries to use her as bait for Silverbolt. During the battle, the confused Transmutate comes to Silverbolt&'s defense. When Rampage again faces off against Silverbolt, Transmutate leaps into the line of fire and is destroyed.
