Trapped on a primitive planet, two opposing factions, the Maximals and the Predacons, of Transformers, a race of sentient robots, fight over its precious Energon. Soon they discover that there are other forces at work on the planet - a powerful alien race that does not approve of their presence. And as they delve deeper into the planet's history, they uncover a terrible secret, one that must not be allowed to fall into the wrong hands, or their entire race's very existence could be threatened.
Tarantulas infects Rhinox with a virus that causes him to sneeze raw energon, rapidly depleting the Maximal's power cells. Optimus sends out Dinobot and Rattrap to look for an antidote, and they end up having to follow the spider into its underground lair...
A Predacon attack sets off a large energon explosion, leaving a group of Maximals with their optic-sensors non-functional while they try to make it back to the base.
Megatron creates a clone of Dinobot's beastmode, and sends him off to deactivate Sentinel while Terrorsaur traps the real Dinobot in a cave.
Megatron is building a disruptor ray to scramble the Maximals' circuits, but needs an organic lifeform who won't be affected by it to finish putting the shielding into place. He has one of the cave-human children kidnapped, and it's up to Rattrap and Depthcharge to save her.
Realizing that without the Maximals she would never have existed, Blackarachnia actives the Ark's defenses and forces Megatron out of the ship. The Maximals start initial repairs and the time storm subsides a bit, but Optimus Prime's life still hangs in the balance - it could swing either way. Megatron rallies his troops to make sure it swings in his favor.
After Rhinox thwarts a Predacon trap, Megatron decides it's time to test Tarantulas' newest device on him - reprogramming the Maximal into a Predacon. Megatron is certain that the new ally will make overrunning the Maximal base easy, though it seems like the new Rhinox has other ideas.
The Predacons steal the Maximals' rectifier-coil, leaving the Axalon without Energon shielding. Forced to remain in beastmode, the Maximals' mentality becomes closer and closer to that of their organic counterparts.
After installing a hidden camera in the Predacon base, the Maximals watch them destroy themselves during a power-struggle between Terrorsaur and Megatron. Investigating, they find no signs of life, so it looks like they won, and can go back to Cybertron with salvaged parts from the remains of the Predacon ship.
Two young cave-humans are separated from their parents by an attack from Megatron's new transmetal enhanced raptor clones. Optimus chases off the raptors and charges Blackarachnia and Cheetor with escorting the kids back to their homes.
Rhinox detects a Cybertronian probe entering the star system, but is unable to contact it though the energon fields. The only option is build a more powerful transmitter before the probe leaves, but the nearest suitable place is in the middle of Predacon territory.
Blackarachnia is getting tired of the distrust, and when she overhears Optimus and Rhinox discussing removing her Predacon programming, and the fact that it might leave her mindless, she rushes out on her own... straight into the claws of the waiting Dinobot.
The Maximals are preparing to place out a Predacon detection system, but Optimus postpones it due to a fierce storm. Cheetor is however again out to prove himself, and starts setting it up anyway - ignoring the storm until a freak lighting somehow transports him into the Predacon base.
Tigatron discovers a floating island, with a giant obelisk in its center. When the obelisk fries Waspinator and Terrorsaur with a single blast, Megatron decides he wants that power and sends out Scorponok and Blackarachnia to seize it.Watch Now:Amazon
While the Predacons are preparing to strike at the Maximal base by creating a hole in the ground below it, Dinobot accidentally activates the Maximal's new defense system before it's learnt to recognize the Maximals as friendlies.
Scorponok infects Optimus with a virus supposed to make him a coward, but it turns him into a battle-crazed berserker instead. Filled with fury, Optimus attacks the Predacon base alone.
Megatron sends out Tarantulas, Blackarachnia and Quickstrike to build an energon refueling station, though the spiders' scheming complicates even the simplest task.
After repeated ambushes by the Predacons, this time costing the Maximals a stasis pod, Optimus calls Rattrap's loyalty into question, and sends him off into Predacon territory to look for energon. Once there, he is attacked by Terrorsaur, and offers to surrender... and become a Predacon.
Inferno retrieves a golden disk hidden inside a glowing mountain. When Megatron sees it, he decides there are far more important things to worry about than the Maximals, and offers Optimus a truce. Meanwhile, Tarantulas is even more determined to leave the planet than ever.
Afraid of what he's becoming and unable to control it, Cheetor tries to hide his temporary transmetal 2 transformation, leading the others to believe a mutant beast has destroyed him.
Predicting the next stasis pod's landing, Tarantulas knocks out both the Preds' and the Maximals' computer systems. He plans to recruit the protoform robot for himself, but has to let Blackarachnia tag along when she discovers him scheming.
While out surveying the planet, Airrazor and Tigatron trigger a remaining alien site. While the Maximals scramble to their rescue, Tarantulas is already on his way, determined to thwart the aliens' plans.
Unable to jury-rig defenses using parts from the Ark, the Maximals send Rattrap down under water in a small capsule to retrieve Sentinel from wreckage of the Axalon. But Megatron wants to lay his hands on it too, and Rampage and Depthcharge fighting it out in the area, nobody's safe.
Terrorsaur comes across a mountain of energon floating in mid air. He chances robot mode to get a sample, but instead of damaging him, the energon supercharges him. With his newly gained powers he sets out to depose Megatron and then destroy the Maximals.
The Maximal Depthcharge flies into a temporal disruption while out searching for Protoform X, and is sent back in time to the Beast Wars. He and Rampage has some unfinished business, and neither cares if anything gets in their way.
