The episode opens with a majestic bald eagle soaring through the sky. And then Terrorsaur eats it, before spotting a hovering mountain. He investigates, and on seeing it filled with Energon, he decides to transform to scan it, risking the Energon surge. As he tries to collect a sample, he's shocked, and as he thumbles back his hands touch spikes of Energon, and he is super charged, his form visibly bulking up, his voice becoming deeper. Realizing his new found power, he decides to go fight Megatron, and flies off, streaking through the sky like a rocket.
Cheetor sees this, and having learned his lessons from both "The Web" and "Equal Measure", radios back to base to ask if he should investigate decides to follow and investigate without radioing back to base.
From nearby, Cheetor witnesses the whole scene, and runs back to base to report. The Maximals detect him arriving at full speed and figure something must be up. We get to see Cheetor tell Optimus everything he just saw, because why not pad the episode some more? Optimus orders Rattrap to gear up for demolition, and they both go to the flying mountain, Optimus on Rattrap's back.
Tarantulas has been following Terrorsaur, intending to discover his secret and seize it for himself, he uses his harpoon to climb to the floating mountain.
Optimus and Rattrap arrive (despite leaving well after Terrorsaur they show up at the same time as him, in fact, before they left the base they could scan Terrorsaur and Tarantulas having almost reached the mountain), return to beast mode and spy Terrorsaur recharging. Optimus decides he will draw Terrorsaur away, while Rattrap can plant his demolition charges. He'll then return to retrieve Rattrap before the mountain blows. Rattrap doubts Optimus can actually ditch a post-recharge Terrorsaur, but they don't really have options.
Optimus transforms and gets Terrorsaur to follow him, because Terrorsaur is a massive idiot that doesn't know a diversion when he sees one. Optimus dodges Terrorsaur's super charged gunfire by flying about the mountain, while Rattrap places two Demolition charges where Terrorsaur recharges, and returns to beast mode. He then crosses Tarantulas, and both fight in beast mode. You'd think that, with some Tarantulas actually eating rats, this would be an unfair fight, but no, Rattrap holds his own, eventually tossing mud in Tarantulas' eyes as he's charging him, causing Tarantulas to fall of a cliff on a ledge near the bottom of the mountain.
Optimus however starts feeling the effects of being near so much Energon and is forced to land and turn to beast mode. Terrorsaur prepares to finish him off, but Contrived Coincidence means he feels the power drain occur, and transforms to recharge, swearing to return to finish Optimus off. Optimus climbs back up to find Rattrap. Rattrap sees Terrorsaur returns and assumes Optimus is dead, meaning he'll die when the mountain blows. Terrorsaur sees the charges and flees just as they detonate, as does Tarantulas. Optimus climbs back up, tells Rattrap to climb on his back, and jumps off the mountain, as if he transformed, the Energon blast from the mountain would fry him permanently. He catches himself on a branch bellow, allowing them to survive... somehow. Optimus and Rattrap compliment each other on their work, but Rattrap tells Optimus to tell no one he's said that.
Terrorsaur flies back to base, lamenting that he lost his power source, he did get rid of Megatron permanently. Megatron awaits him, fully repaired.
The episode is okay. Not great, not bad. There's no real stake here. It's not like Terrorsaur taking out Megatron makes us fear for the Maximals, especially when we realize he loses his super powers really fast. And Terrorsaur never feels more threatening that Megatron does, even with his powers. It feels like they could've made something better out of this. For example, Tarantulas is in the episode just so he can have a fight with Rattrap to pad things out a bit.
- Tarantulas shows his own independent streak and ambitions for the first time. They will become a major deal in later episodes.
- Natural Energon is never seen make things float again.
- The Predacon base's defense grid being spread all over the surrounding terrain becomes relevant in the future. We'll soon see the Predacons and Maximals develop different means for base defense.
- Originally, the series was to feature another Predacon, Insecticon. He was written out when it became apparent how expensive and complex making new characters in CGI is. Most of the scripts were re-written to remove him. Except this one, who only had minor touch ups. His lines were simply given to Waspinator. This is why two of Waspinator's three lines do not carry his verbal tic of referring to himself or others in the third person: "Not me." and "If you are second in command, what is your command?" The script can still be found online
.
- Megatron mentions Terrorsaur has learned to not challenge Megatron before. We've never seen Terrorsaur do it to Megatron's face, so unless Dinobot filled Megatron on the events of Equal Measure, this took place offscreen.
- Terrorsaur eating a bird in flight is inspired by his toy's bio, which says he likes to fly with his beak open onto incoming bird formations.
- While riding on Optimus' back, Rattrap complains that if he wanted to fly, he'd have been a bat, not a rat. Optimus' first Beast Wars toy transformed into a bat.
- Terrorsaur's shoulder guns are seen for the first time.
