Destruction rains down on the Maximals as Megatron unleashes the weapons of the Nemesis. Optimus orders a desperate attempt at getting the Ark airborne.

The spacecraft leaves, but not before revealing the second moon's true purpose - planet destruction. As it gets ready to fire, Optimus and the others return to the Axalon only to find Rhinox and Dinobot off-line... and spiders in their basement.

While Inferno, Quickstrike and Waspinator go looking for a new ""colony"", Megatron discovers one of Tarantulas' secret projects - the reactivation of the gigantic Decepticon warship that shot down the Ark before it crashed into the sea.

An alien spacecraft lands and captures Airrazor while she's examining it. Optimus and Rattrap enter to rescue her, while the Predacons stand outside, ready to break the truce at a moment's notice.

The aliens, the Vok, send Tigerhawk to Earth to stop Megatron's meddling with time. He crashes into the Predacon base, but the Predacons have no intention of takeing this lying down... especially Tarantulas.

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.

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.

During a fierce storm, the immortal spark of the Deception Starscream lands on the planet and takes control of Waspinator's body. He convinces Megatron to let him help with an attack on the Maximal base, which he knows to be offline. His skills are after all considerable... but then again - so is his treachery.

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.

Rhinox spots a falling stasis pod while surveying unused Predacon territory. He is the first to arrive, but the pod is damaged and he is unable to activate the DNA scanner. Unless he can get it working again soon, the protoform's spark will be extinguished.

Blackarachnia attempts to use the transmetal driver on herself, but all it accomplishes is to disrupt her Predacon programming, making it deteriorate quickly to the point that it will make her mindless unless it is removed.

A stone circle, showing abnormal energon readings, is activated during a Predacon attack and attracts an alien probe. While investigating it, Optimus is disintegrated, leaving the Maximals bickering over who's in charge, while the Predacons prepare to attack.

One of the Maximal stasis pods, put in orbit before the crash, falls down in the north, and Optimus rushes out to retrieve it. Unfortunately, Megatron anticipates this and sets up an ambush that nearly kills the Maximal leader. Without a flyer, the Maximals race to the pod in hope of getting it before the Predacons reprogram the dormant robot inside.

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.

Optimus and Rattrap race to the island to assist Tigatron and the wounded Airrazor, while Scorponok and Blackarachnia make their way towards the obelisk.

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.

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.

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.

Using a newly discovered blank protoform, and his part of Rampage's spark, Megatron creates a clone of Dinobot incorporating his enhanced transmetal 2 technology. Discovering the experiment, Cheetor and Depthcharge try to destroy the equipment, but it is activated during the fight and blows up - the cat getting caught in the blast.

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.

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.

Tigatron accidentally blows up a Predacon ammo storage, and the resulting avalanche kills a feline friend. Tired of fighting, he sets of alone, renouncing his membership from the Maximals.

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.

Optimus is implanted with one of Tarantulas' bugs, this one letting Quickstrike remote control him. After securing the Maximal base, Megatron goes after the original Megatron's spark, hoping it will give him equal power to Optimal Optimus.

Dinobot challenges Optimus for leadership of the Maximals, but while they fight the Predacons launch an ambush.
