Beast Wars: Transformers

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

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.

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.

After repeated ambushes by the Predacons, this time costing the Maximals a stasis pod, Optimus calls Rattraps 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.

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.

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.

Megatron creates a clone of Dinobots beastmode, and sends him off to deactivate Sentinel while Terrorsaur traps the real Dinobot in a cave.

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.

Predicting the next stasis pods 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.

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.

Tarantulas infects Rhinox with a virus that causes him to sneeze raw energon, rapidly depleting the Maximals 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...

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.

The spacecraft leaves, but not before revealing the second moons 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.

A new breed of transformer, robots with two animals mixed together when in beast form.

Megatron sends out Tarantulas, Blackarachnia and Quickstrike to build an energon refueling station, though the spiders scheming complicates even the simplest task.

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.

Cheetor discovers a huge stasis pod, containing Protoform X - a failed Maximal experiment that created an indestructible spark but drove it insane in the process. When Predacons arrive, a fight breaks out over it, setting off an energon storm that leaves Blackarachnia and Silverbolt together damaged, having to fend for themselves - While Protoform X awakens, looking for a victim...

A series of earthquakes uncovers a heavily damaged stasispod. Out of it comes a freakish robot - barely sentient, but with extremely powerful weapons. Scoffed at by the others, both Silverbolt and Rampage sense a kindred spirit, each in their own way.

Megatron is captured, but the battle used up too much of the cruisers energon supply for there to be enough for the travel back to Cybertron. While Ravage interrogates Megatron about where they might find more, Primal confronts Silverbolt about his relationship Blackarachnia, leading the Fuzor to go off on his own to find her.

Realizing that without the Maximals she would never have existed, Blackarachnia actives the Arks defenses and forces Megatron out of the ship. The Maximals start initial repairs and the time storm subsides a bit, but Optimus Primes life still hangs in the balance - it could swing either way. Megatron rallies his troops to make sure it swings in his favor.

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, nobodys safe.

Using a newly discovered blank protoform, and his part of Rampages 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.

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.

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.

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

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