After the Decepticons' spaceship is found by archaeologists, Megatron takes from it the "Heart of Cybertron" - tiny and extremely powerful energy maximizer. Once Megatron installs the Heart inside his chest, he gains extraordinary powers, enabling him to defeat many Autobots by himself. Perceptor comes with radical plan: by using the trans-mat reduction beam, he, Bumblebee and Brawn are minimized to microscopic size, and sneak into Megatron's body in order to disconnect the Heart - while Megatron is on his way to the Autobots' base. Will the Microbots reach their target in time before Megatron destroys their friends? Written by Optimus Prime

When Megatron steals the powers of the heart of cybertron he becomes super powerful, able to shoot lasers out of his fingers. The autobots decide to shrink Perceptor, Bumblebee, and Braun so they can go inside of Megatron to take the heart of cybertron from Megatron.

A pretty interesting episode. The heart of cybertron makes Megatron quite destructive and powerful. ALso I like the whole shrinking aspect and how the autobots travel through Megatron's insides. Perceptor is important, but truly I think he is one of the worst transformers out there.

This episode has a lot of funny parts. Like how the decepticons get drunk off of energon, or how Starscream gets attacked by a snake. Also it has a great duel between Ravage and a real jaguar.

A good episode. One that I recommend.
