Season Two (1985-1986, 49 episodes)

Four million years ago they came from Cybertron, a world composed entirely of machinery...a world torn by an age-old war between the heroic Autobots and the evil Decepticons. These incredibly powerful living robots capable of converting themselves into land and air vehicles, weaponry, and other mechanical forms, continue their conflict here on Earth. They are THE TRANSFORMERS.

Using spare parts Sparplug creates Autobot X, however the robot is shown unstable and is put into storage. Later that day, Spike is badly injured in a firefight with the Decepticons. To save his life, the Autobots transfer his mind into Autobot X so the doctors can operate on his body. With an unstable mind and Megatron's goading, Autobot Spike turns against the Autobots, but reverts when he nearly kills Sparkplug. Spike's body makes it through the operation, and Spike's mind is returned to his body.

18. Changing Gears
Gears, the grouchy Autobot, is abducted by the Decepticons and Megatron steals his personality cartridge to use in his latest plot, making Gears friendly to them.

21. Traitor
The Decepticons capture an unstable power source (electrocells) and seek to exploit them, with the Insecticons' help. Mirage's plan to turn the Insecticons and Decepticons against one another backfires when he is mind-controlled by Bombshell. Under the Insecticon's influence he leads the Autobots into a trap. Ratchet removes Bombshell's cerebro shell and learns the truth, however. In a final battle with Megatron, the electrocells are destroyed.

22. The Immobilizer
Wheeljack has created the Immobilizer, a new weapon that can temporarily stop any Transformer in its tracks. The Decepticons manage to steal it partly due to Carly (first appearance) distracting Ironhide from his lookout post. During the battle which follows, Ironhide rescues Carly from the Decepticons, but they have made the Immobilizer's affect permanent and start immobilizing the Autobots. With the assistance of Brawn and Jazz, Spike and Carly manage to reverse the effects of the Immobilizer to save the Autobots and the Immobilizer is destroyed.

26. Enter the Nightbird
The Decepticons, working out of a desert base, steal an experimental female ninja robot named Nightbird. They plan to use her to steal the Autobots' computer chip containing information on the world's energy sources. Nightbird succeeds in stealing the chip from Autobot headquarters, but is confronted and trapped by the Autobots. The Decepticons come to her aid, but she is ambushed by the jealous Starscream. The Decepticons chase after the fleeing Starscream, leaving Nightbird and the chip with the Autobots.

27. A Prime Problem
The Decepticons discover a chasm full of crystals that destroy machinery. In a plot to destroy the Autobots, they create a duplicate Optimus Prime and confuse the Autobots as to who is the real Optimus Prime. The Autobots and Decepticons fight near the chasm and the duplicate Optimus Prime destroys a duplicate Starscream to further confuse the Autobots. The Autobots are just about ready to follow the duplicate Prime into the chasm and to their deaths when the duplicate (controlled by Megatron) breaks the masquerade by not showing any concern for Spike's welfare. The Autobots knock the fake Optimus Prime into the chasm where it is destroyed.

28. The Core
Megatron constructs a drill to reach the center of the Earth and tap the energy there, despite Starscream's warnings that this will destroy the planet. Meanwhile, the Autobots have come up with a way to control Devastator. In their attack on the drill, Megatron activates a countermeasure. The conflicting signals cause Devastator to go berserk. Only by cooperating are the Autobots and Decepticons able to control him again. Devastator destroys the drill and Earth is safe.

29. The Insecticon Syndrome
The Autobots and the Insecticons engage in battle in a forest where the Insecticons are eating the trees. After beating the Autobots, the Insecticons go along with the Decepticons to a base containing a power source. When the Insecticons feed on the power, it turns them into big bugs and makes them very unstable. In the process, they kidnap Soundwave and turn him into their slave and badly damage Wheeljack and Ironhide, forcing the Autobots to retreat. Megatron and Starscream realize that Soundwave and all the other Decepticons are under Insecticon control. Bombshell launches two cerebro shells, one hits Starscream and he becomes controlled, but Megatron crushes the other one before it hits him. Optimus Prime warns Megatron that any blast that hits one of the Insecticons could destroy them all. The Autobots create three antidotes to prevent this from happening. Megatron is forced to work with the Autobots and transforms to fire the antidotes. Bombshell and Kickback are saved and return to normal size, but Shrapnel explodes before the antidote put in him by Spike can work. The Decepticons are freed from Insecticon control and Bombshell reassembles Shrapnel. The Insecticons retreat with the Decepticons chasing them.

Powerglide and Bumblebee discover a prehistoric island filled with dinosaurs. The Dinobots' destructive fighting tactics end up causing harm and havoc to the Autobots during a demonstration. As a result, Optimus Prime orders the Dinobots to be secluded on the island where they will train to better control themselves in combat and to be able to work better as a group when they fight. The Decepticons find out about the island and want to tap the many natural resources for power. Megatron eventually discovers that the island is rich in energy. The Decepticons arrive and proceed to turn the energy into energon cubes. When they are confronted by the Dinobots and Megatron stampedes some dinosaurs to force the Dinobots into a tar pit, trapping them.

31. Dinobot Island Part 2
As the Decepticonss steal energy from the island to fill energon-cubes, it disrupts the time-space continuity, causing other timewarps to appear at random across the world. The Autobots have to send mammoths, cowboys, and other historic relics back through the timewarps before they are trapped in modern day. The Autobots eventually figure out the cause of the timewarps and send a force to stop the Decepticons on Dinobot Island. They arrive on the island, but are taken out rather handily. All does not look well until the Dinobots are revived and stop the Decepticons. Optimus Prime sees they have learned to function better as a group and allows them to return to the Autobots.

32. The Master Builders
Grapple has designed a solar energy-collecting tower, however Optimus Prime will not allow its construction on the grounds that it's too difficult to defend, and the consequences would be too great should Megatron obtain it. Hoist and Grapple go to sulk in the desert, and the Constructicons dupe them into believing that they have deserted. They build the tower, supposedly for the sake of building it, but after it is finished the Constructicons turn it over to their leader and the Autobots are forced to destroy it.

It is violently unstable, and could explode catastrophically at any time. Perceptor, Brawn and Bumblebee are shrunk to micro size to sneak into Megatron's body and retrieve the component. The search is difficult, given Megatron's immune system, and the argument between Perceptor and Brawn of mind over power, but Perceptor finally earns Brawn's respect as the trio finds the component and manages to escape Megatron and shoot the self-destructing component just in time.

The Decepticons meet up with a lord, while the Autobots team up with a knight whose daughter Spike is attracted to. Spike gets a full suit of armor and rides Warpath in a joust against Rumble and Ramjet. The joust is not spectacular because the Transformers are low on fuel. The Decepticons kidnap the knight's daughter and are able to repel the Autobots because their human ally provided them with an energy source; right before they betrayed him. They also have an advantage because they have made primitive gunpowder. The Autobots eventually win, the daughter agrees to marry her kidnapper, and the Transformers go back to the cave with a wizard who promises to send them home.
