Beast Wars: Transformers - Season 2

After the Transwarp explosion, which results in the destruction of the Vok's artificial moon, unleashes an Energon wave, the impact of which kills Terrorsaur and Scorponok. Rattrap and Cheetor gain new Transmetal forms from its irradiation, but so do Megatron and Tarantulas.

Two Fuzors – Silverbolt and Quickstrike – are created from damaged stasis pods, and Megatron is able to convince them to join the Predacons. Meanwhile, Tarantulas is able to download his spark back into his new Transmetal body. Dinobot steals the Golden Discs after he and Waspinator find out that the planet they are on is prehistoric Earth. During this episode Silverbolt was thought and believed to have been a Predacon and the only one that is based off a mammal, as he is a combination of a wolf and eagle.

Thanks to the efforts of Rhinox, Optimus Primal is revived as a Transmetal, and after a battle with the Predacons, Silverbolt disbands the Predacons and joins the Maximals, as he stated in the previous episode that "Terrorize" is a word he doesn't like "the taste of".

Tarantulas, Quickstrike, and Blackarachnia are sent to secure a new Predacon post, but their conflicting intentions and the intervention of Rattrap and Silverbolt complicate things.

While on a reconnaissance mission, Dinobot is captured by the Predacons. Instead of fighting them he announces that he wants to be a Predacon again. He is able to prove his loyalty by defeating Quickstrike, but when he has to kill Rattrap, he starts to reevaluate his allegiance.

Tigatron and Airazor are beamed into space after discovering a new alien device. The Maximals and Predacons battle for control of the weapon.

Megatron gains control of the alien weapon, and plans to use it to conquer Cybertron. The Maximals are forced into an uneasy alliance with Tarantulas in order to stop him.

The psychotic Protoform X crashes on Earth and attacks Maximal and Predacon alike. Eventually, Megatron removes his Spark, using it to blackmail him into joining the Predacons under a new name: Rampage. During this time, Silverbolt and Blackarachnia begin a relationship.

The Predacons attempt to annihilate a colony of pre-humans to change the outcome of the future war between the Autobots and Decepticons. With no other Maximal around, Dinobot faces the whole Predacon army alone in battle. He tries to prevent them from changing history, even if it means sacrificing his life.

This episode is widely considered to be one of the best episodes in Transformers history and the Region 1 DVD describes it as the "powerful series centerpiece". It is also considered to be the episode which catapulted Dinobot into the Transformers Hall of Fame in 2010.

A faulty Transformer named Transmutate is created from a damaged stasis pod. Silverbolt and Rampage compete for its trust, but Transmutate is killed by its own power while attempting to break up the fight between Silverbolt and Rampage.

The Tripredacus Council is hit by the explosion caused by the destruction of the alien device in "Other Voices", and they recognize the signal as being from Megatron's ship. After blocking the wave from reaching the Maximals, they send a covert operative to capture Megatron. The agent turns out to be ex-Decepticon Ravage, who makes an alliance with the Maximals in order to capture Megatron.

Optimus and Cheetor attempt to recover an Energon stash, but are damaged when it is destroyed by Inferno. Meanwhile, Silverbolt follows Blackarachnia to a mountain that Megatron has been interested in, and Megatron wins the loyalty of Ravage by showing him a message left by the original Megatron.

Rattrap manages to destroy the Predacon ship, taking Ravage with it. Rampage is damaged due to an automatic missile fire. Meanwhile, Blackarachnia and Silverbolt find what Megatron really came to Earth to find: the Ark, the ship that carried the Autobots and Decepticons that would go on to fight in the Great War of 1984. After breaching Teletraan 1's defense system Megatron proceeds to the control room and fires an energy blast on the dormant body of Optimus Prime, causing a time storm that begins erasing the Maximals from existence.
