Microbots

Perceptor, Brawn, and Bumblebee must shrink themselves to go inside Megatron and retrieve an artifact, the Heart of Cybertron, that is giving him enormous power.

Detailed synopsis
While digging for Mayan artifacts in South America, a group of archeologists stumbled upon an ancient spacecraft. As news of the discovery was broadcast on the news, Soundwave and Megatron recognized it as the Decepticon ship they had travelled to Earth in four million years ago. Megatron stated that there was something on that ship which he wanted, and set out to get it.

Meanwhile, at the Autobots' HQ, Perceptor was using a shrinking-enlarging device to repair one of Ironhide's memory chips while being insulted by Brawn for not being a soldier. Bumblebee walked in and tried to make him stop, when Optimus Prime ordered Brawn and Bumblebee to follow him to South America along with Ratchet, to stop Megatron from obtaining what he wanted.

As Megatron's troops blasted their way through a rainforest in order to avoid satellite detection, Starscream managed to miss a tree and was attacked by a giant snake, to the amusement of Rumble. Meanwhile, Ravage met his match in the form of a real Jaguar. The Autobots arrived and decided not to burn the forest down, because Optimus says "that's not our style".

Megatron got through the forest first, and reached the ship. Blasting it open, he retrieved the ship's energy core, the Heart of Cybertron. Hook implanted it into Megatron's torso, vastly increasing his power level. Optimus Prime then arrived and ordered the Autobots to attack, but they were all defeated by Megatron's new ability to continously fire energy from his fingertips. The Autobots only managed to escape by destroying a hill, burying the Decepticons under rubble.

While Optimus Primce created a force-field to keep Megatron at bay, Perceptor created a plan to shrink himself, Brawn and Bumblebee to microscopic sizes in order to infiltrate Megatron's body and disconnect the Heart of Cybertron.

Meanwhile, the Decepticons sat around and got intoxicated on energon. After Megatron rambled on about the "good ol' days" and passed out, Powerglide delivered the tiny Autobots into his body. This caused him to wake up and go to destroy the Autobots himself, as the rest of his forces couldn't stay on their feet.

Perceptor, Brawn and Bumblebee made their way through Megatron's body, avoiding his electro-sanitizers and riding his evil brain impulses. They eventually reached the Heart of Cybertron, disconnected it, and got out of Megatron just as the shrink-ray was wearing off. Brawn threw the Heart 2000 miles into the sky, at which point Perceptor blasted it. After this, Brawn showed much more respect for Perceptor.

Notable quotes
"Nice scenery." "Yeah, now lets waste it! I hate nice things."
 * -- Rumble and Bonecrusher, the latter sounding very familiar.

"We use my matter reduction beam to shrink down to microscopic size. Then, we crawl into Megatron, and rip the blasted heart out!" "What do you think of his intelligence now, Brawn?" "I reserve judgement."
 * -- Perceptor, Optimus Prime, and Brawn.

Megatron: "Decepticons: a toast. To the imminent destruction of the acursed Autobots!" [The Decepticons begin drinking Energon] Starscream: "Energy! We won't need to conserve after tomorrow. We can bleed this planet dry!" Rumble: [hiccups] "Boy, these are good. [hiccups] I needed to refuel. Energy!" Megatron: "Energy! Energy!" Thundercracker: "Hey! This stuff's the greatest!" [passes out] Megatron: "Ah, those were the good ol' days, back on Cybertron...Didn' half to...sneak around in these...ugly Earth disguises." [Powerglide arrives] Powerglide: "Time to cut the jets and glide!...What in the world?" Megatron: "Good ol' Cybertron! Land...of the metal moon!"
 * -- The Decepticons and Powerglide in what is possibly the funniest scene of the original cartoon.

"Let's bash brain!"
 * -- Brawn.

Animation and/or technical glitches

 * When Optimus is telling the Autobots to leave the base, Perceptor has a red Decepticon symbol.
 * When the Constructicons laugh at Starscream, they use Rumble's laughter while Rumble is talking. This laughter is reused a second later by Rumble himself when he is done talking.
 * Most of the Autobots do not follow Optimus to South America, but appear anyway halfway through the battle with Megatron.
 * Ratchet says "do" twice in a row when talking to Bumblebee at the end.

 * The Decepticon ship in this episode was later dubbed the Nemesis by the episode of the same name in Beast Wars. The ship itself is not named in "Microbots".

Miscellaneous trivia

 * The pulsating sound heard when Perceptor and company approach the Heart of Cybertron within Megatron is the same one used aboard the Dalek spaceships on all episodes of Doctor Who since 1964.
 * Megatron apparently has a wristwatch on his left wrist, which he looks at while flying around (causing concern for the Autobots within his shoulder joints).
 * This episode is perhaps the only one to show drunken Decepticons. Which is a real bummer, because they make funny, happy drunks.
 * At one point, Brawn proposes killing Megatron from the inside. Perceptor stops him, saying that if he fell while flying, the impact could detonate the Heart of Cybertron.  Once Megatron's landed, this wouldn't seem to be a concern anymore, but the Autobots still choose to remove the Heart of Cybertron rather than bashing brains.  Perhaps even a short fall would have been enough?
