Beast Wars: Transformers - Season 1 (1996)

Cheetor disobeys a direct order from Optimus by leaving the Maximals base to place survey posts on the planet. A lightning bolt strikes one of the posts, creating a direct teleportation route between the Predicons' and Maximals' bases.

Optimus Primal is abducted by an otherwordly probe, leaving the Maximals leaderless. Amidst their bickering and squabbling, the Predacons prepare to launch an attack.

Terrorsaur discovers a floating mountain, rich with the mineral Energon. With a surge in his power, he scraps Megatron and takes control over the Predacons. Now the Maximals must destroy the mountain to stop his power-mad reign.

A stasis pod, containing the spark-soul of a robot, lands on Earth. Both Maximals and Predacons race against time to claim the spark as one of their own.

After being led into a trap and losing a stasis pod to the Predacons, Dinobot accuses Rattrap of working with the Predacons as the Maximal that led them there. To everyone's shock, Optimus agrees with this suspicion and sends Rattrap on a mission near Predacon base to test his loyalty. When Rattrap is beaten by Terrorsaur in battle, he surprises all by not only begging for mercy but swearing allegiance to the Predacons. Is Rattrap really a traitor?

The Maximals are elated to find that a Cybertron probe looking for their stranded ship has arrived. However, the Predacons don't wish for them to be found. Tarantulas introduces a locking lens, which can trap the Maximals in beast mode. This makes the Maximals unable to finish their beacon to contact the probe. Are the Maximals stranded for good?

Scorponok plants a personality-modifying virus on Optimus Primal which will render him a cowardly, submissive weakling. But the virus malfunctions, and Primal gets very, very angry.

A prank from Rattrap causes the Maximal ship to turn on its residents with its new defenses. Determined to fix his fault, Rattrap journeys into the malfunctioning ship to reboot the system.

An explosion at the Predacon base leaves no survivors, and the Maximals assume they have scored a final victory in the Beast Wars. However, Dinobot makes an investigation that changes everything.

Megatron becomes impressed with the Maximal Rhinox, capturing and reprogramming him into a Predacon. Unfortunately, an evil Rhinox ends up doing more harm than good within the Predacon ranks.

Megatron introduces an evil clone of Dinobot, different than the original in that it can only stay in beast mode. With the real Dinobot incapacitated, the clone begins to run amok among the Maximals. When it comes down to Dinobot against Dinobot, which one will win?

When a stasis pod falls to Earth, a race ensues between Maximals and Predacons to collect it. But when it is discovered to be damaged, the Maximals attempt to protect and defend it from a Predacon attack.

In the aftermath of a Predacon attack, Tigatron comes upon a strange floating island, and settles down on it to lead a peaceful, content life. However, Blackarachnia and Scorponok are not far away.

A skirmish occurs between Maximals and Predacons for control of a floating island: the Maximals for its use as a base, the Predacons for its destructive capabilities.

Tarantulas and Blackarachnia team up to obtain the newest stasis pod. The pod births Inferno, a deranged Predacon who believes himself to be an ant rather than a robot. While Blackarachnia works with Inferno, Tarantulas takes the true prize he wanted: the stasis pod. Maximal Tigatron manages to destroy the pod Tarantulas has taken, but finds himself trapped in Predacon grounds against the spiders and Inferno.

A Predacon attack on the Maximal base leaves it malfunctioning, necessitating the Maximals to remain in beast mode until it is repaired. However, the longer they stay in beast mode, the more their animal sides start to take control.

A Predacon attack blinds a Maximal squad and now Rhinox, Rattrap, Cheetor and Dinobot must embark on a voyage through darkness, relying on each other, to make it back to home base.

Waspinator is taken over by the spark of Starscream. The Predacons use his new power and tactical knowledge to take over the Maximal base.

Rhinox is contaminated with an energon depleting virus. Dinobot and Rattrap are forced to put aside their differences to find the counter-virus.

When a battle takes the life of a close friend, Tigatron considers abandoning the Beast Wars.

The discovery of a new golden disc causes Megatron to declare a truce. The Maximals set out to peacefully discover just what their enemy has found.

The mysterious aliens whose artifacts the Maximals and Predacons have been stumbling across arrive. Disappointed by the harm done to their experiments, they set out to destroy the planet.

The aliens transform the second moon into a massively powerful weapon. To save the planet, Optimus uses the stasis pod that Tarantulas planned to escape in to fly to the weapon and generate a transwarp portal to destroy it.
