The Decepticons are approaching the Ark, and Autobots Transform. Soundwave, Rumble and Lazerbeak distract the Autobots. Optimus’s warning diode is pulsing, which sounds creepy and gross.
Megatron apparently has invisibility spray, now. He and Starscream test it out on themselves, and effortlessly infiltrate the Autobots recharging chambers. The Decepticons leave, and the Autobots figure they just whooped ‘em too fast for the Decepticons to handle.
The next day, Optimus orders the Autobots to recharge, because they’ve got a rich, full, day ahead of them. Whoops! Now all the Autobots are under Megatron’s control, and Order #1 is to smash Teletraan 1. Optimus obliges, and thank god for that.
Bumblebee and Jazz are hanging out in the desert, and Jazz wants to test his new, rad, giant speakers. Bumblebee is lame, so he leaves. Back at the Ark, Bumblebee is forced into the recharging chamber. In the desert, Jazz starts an avalanche with his speakers.
Jazz and the guys head back to homebase, and Bluestreak starts shooting at Jazz, who beats him down. They release Bumblebee from his chamber before he’s converted. After reactivating Teletraan, it explains what happened and apparently Megatron’s invisibility spray is kind of like Wonder Woman’s invisible plane, in that it’s more like an “outline spray.” They ask how many of the Autobots were converted, and Teletraan says “All of them.”
Break.
Optimus and the other Autobots are attacking the Air Force base. Jazz rightly asserts that he and Bumblebee cannot possibly fight Prime and the other Autobots alone, but Bumblebee doesn’t give a shit and heads out. Clumsy exposition with Scientist Lady and her new Solar Satellite which is about to be launched. She escapes out the window and taunts the ‘bots. Prime blows up some planes.
Bumblebee and Spike show up, and explain what is happening. Spike shouts at him to stop, but he won’t listen. Bumblebee is sad.
Megatron bursts into the launch center and blows stuff up, then yells at some scientists. He sets the satellite to launch, and takes off. In Two Earth Hours he’ll be on a rocket back to Cybertron, and blah blah perpetual motion blah blah.
Bluestreak wakes up just in time to be the test subject for Sparkplug’s new “goodness transfusion” process. Goes like this: “1. Drain evil, 2. Add good” seems simple enough. They “fix” Bluesteak and head out to do the others, starting with Hound. Ratchet is about to smash Scientist Lady, but Bluestreak converts him before he can.
Bumblebee is still working on Prime, who is about to beat his ass, but we get a commercial instead.
Break.
The converted Autobots go after Skyfire, who is still under Megatron control and blowing stuff up. Once he’s converted, they load in, and go after the others.
Bumblebee is still winging at Prime, who hasn’t smashed him yet, and Skyfire shows up with the other Autobots. Just as they’re about to convert him, Prime splits into his 3 components. Bumblebee won’t shut up. Shut up, Bumblebee. SHUTUPSHUTUP. He manages to attach the converter to Prime, and Prime gives him a robo hug.
Prime says blah blah Cybertron, Scientist Lady satellite, blah blah Megablah. They load in to Skyfire.
At launch control, the satellite rocket is about to launch with Megatron and the ‘Cons inside. It does, but the Autobots show up and pile out of Skyfire to take it down. Robot Fight on the rocket, and Jazz Has A Plan. He uses his badass new speakers to sonic boom the rocket, which is apparently a fast and easy way to blow up rocket fuel tanks. Megatron and the Cons abandon rocket.
Back at the Ark, Prime lavishes praise on Bumblebee. Rachet and Sparkplug argue over who is more awesome, and everybody loses.
Moral of the story: Bumblebee is totally gay for Optimus. Neither Rachet or Sparkplug are awesome, and Scientist Lady is basically useless.
