Attack of the Autobots (Transformers Generation 1)

A Decepticon sneak attack on Autobot headquarters is actually a diversion while Megatron and Starscream use a temporary "invisibility spray" to sneak inside. Megatron sabotages the Autobots’ recharging chamber with a personality destabilizer device. After the Autobots recharge the next day, they have a sudden change of heart and are now Decepticon slaves. Optimus Prime obeys Megatron’s first order and smashes Teletraan I.

Jazz and Bumblebee, the only unaffected Autobots, are on their way back to Headquarters. Bumblebee makes it back first, and evil Bluestreak forces him into the recharging chamber. Jazz, Sparkplug and Spike arrive and save Bumblebee from being brainwashed. Sparkplug repairs Teletraan 1, who tells them that the rest of the Autobots are now evil!

Meanwhile, Optimus leads the Autobots on an attack at the local Air Force base, where they begin trashing military jets. Spike and Bumblebee rush off to the base to stop them, and Sparkplug and Jazz stay behind to work on a cure. All of this mess was started just so Megatron could steal a human solar energy satellite being launched the same day. The Decepticons take over the rocket base and plan to take the rocket and satellite back to Cybertron.

At headquarters, Sparkplug cooks up a bunch of attitude exchangers that will "First, drain evil. Second, recharge good." He and Jazz round up Ratchet, Hound and Skyfire and change them back to good using the devices. Skyfire gives them a lift to the Air Force base, where they manage to change the rest of the Autobots, except for Optimus Prime. The devices pacify Prime’s combat deck and Roller, but Prime is still on a rampage. Bumblebee takes it upon himself to change the Autobot leader back and succeeds. Optimus gives him a nice, big hug for his trouble. Back at the rocket base, Megatron and the Decepticons have boarded the reprogrammed rocket and take off. The Autobots intercept them aboard Skyfire. Prime and Ratchet detach the satellite while Jazz uses a "musical sonic boom" to disable the rocket. The Decepticons abandon it without any further resistance and retreat. Skyfire takes everyone into space and Prime throws the solar satellite into orbit.

Finally back at headquarters, Prime thanks everyone for helping out, especially Bumblebee. But then Ratchet gets jealous and claims credit for firing the attitude exchangers (which was actually Hound’s idea. Hmmm…). Jazz reminds everybody that they have to fix all of the jets that Optimus Prime smashed at the Air Force base. Spike breaks the tension with a lame joke that his dad finds hilarious and we fade to black.
