Beast Wars

As the Maximals begin to fade from the time stream, Blackarachnia switches sides and saves Optimus Prime with a life-support machine. The time storm fades, but Prime is still in danger so Optimus Primal takes Prime's spark into his body to stabilize it until Prime's body is repaired.

Depth Charge, a Maximal from Colony Omicron, arrives on planet Earth looking for Protoform X, wanting revenge on Rampage for killing his comrades long ago. Depth Charge's frustration alienates him from the other Maximals.

After failing to set up base defenses, the Maximals attempt to salvage Sentinel from the wreckage of the Axalon. Rattrap pilots a submarine into the submerged ship, where he is attacked by Rampage. Depth Charge arrives, but only wishes to kill Rampage. Without Depth Charge's help, Inferno and Waspinator steal Sentinel from the Maximals, and it is installed into the Predacon base.

11/15/1998Megatron sends several prototype Transmetal II cyber-raptors to attack the early humans and the Maximals. Depending on who perfects it first, the new technology has great potential in determining the outcome of the war.

Megatron creates a Transmetal II clone of Dinobot, and Cheetor and Depth Charge attempt to interrupt the process; instead, Cheetor is presumed dead after he is exposed to the machine in an explosion. The Predacons soon come under attack from a mysterious feral beast, as a heavily damaged Cheetor returns to Maximal base.

After returning to base, Cheetor has nightmares and soon transforms into the beast from the previous episode. The other Maximals begin to hunt the creature, unaware that it is Cheetor. Megatron claims ownership of the new Transmetal II Cheetor, and sends Dinobot II to capture him. Cheetor eventually harnesses his new form.

When Optimus decides to surgically remove Blackarachnia's Predacon core, without regard for the risk to her, she runs away, and is hunted by Dinobot II.

2/18/1999Megatron kidnaps a young protohuman, Una, to finish a giant disruptor ray that targets Cybertronians. Una follows her directions from Megatron but Rattrap and Depth Charge arrive and save her when the child destroys the machine unintentionally.

Blackarachnia attempts to become a Transmetal II with the help of the alien device she had stolen.

During an attack on the Maximal base, Optimus is hit with a burrowing cyberbug that allows Quickstrike to take control of his body. Tarantulas and Quickstrike form an alliance in order to destroy the Ark and Megatron.

Quickstrike is put to trial for his betrayal of Megatron, but it is interrupted when the Vok send Tigerhawk to stop Megatron's interference with time.

The Nemesis has proven to be powerful and dangerous under the now-insane Megatron, killing both Maximals and Predacons alike.
