Transformers Prime/Recap/S1 E22 Stronger Faster

Ratchet checks out a sample of synthetic energon he's created, watched by Raf. Approving the stability of the energon, Ratchet tries it on a test engine, and it works fine. Raf's keen to try it on Bumblebee, but Ratchet says it'll require more testing first. Meanwhile, the base sensors pick up energon movement, but before Optimus Prime gives the order to roll out, Ratchet warns him about the depleted state of their energon reserves. Once Prime's team departs, Ratchet has the idea to try the synthetic energon on himself. The injection causes him to lose consciousness, and Raf rouses him from lying on the floor shortly afterward. The synthetic energon appears to be a success, giving him more fuel efficiency and better motor functions.

Meanwhile Prime's team chases Knock Out and Breakdown through an icy canyon. The Decepticons aren't in any hurry to bridge out, as they're trying to "help" the Autobots run out of energon. Some Vehicons flying overhead blast the sheer sides of canyon, causing a rock fall that blocks off the Autobots' path. Arcee manages to drive over it in her motorcycle mode, despite Prime's warnings, and races after the two Decepticons, only to be hit by missiles from the Vehicons. She is swiftly surrounded by Decepticons, and things look grim until Ratchet comes flying through the Ground Bridge and begins laying into them with gusto. Knock Out and Breakdown assume that the Ratchet's a new Autobot, but are forced to retreat as Optimus, Bulkhead and Bumblebee come into view, firing at them. Ratchet finishes off the last of the Vehicons, to stunned looks from his teammates.

Back at base, Ratchet reveals his secret to the other Autobots, but Optimus doesn't think it's a good idea to test the synthetic energon on Autobots, and he underlines the importance of Ratchet's job as medic. Sometime later, Ratchet's retelling his fight to Bulkhead, and in demonstrating a move, manages to throw his fellow Autobot through a nearby wall. The other Autobots are startled at his new personality. Ratchet goes and injects more of the synthetic energon into himself. When the sensors light up once more, Prime prepares to roll out again, but Ratchet volunteers to go along.

As they head through a mountainous area, Ratchet moves ninja-style at the front of the team. They soon find some Vehicons and a miner drilling into a rock face, and Ratchet immediately moves in. When the miner makes a run for it, Ratchet gives chase and knocks him down with a well-thrown rock. The other Autobots find Ratchet forcibly interrogating the miner with his blowtorch. Optimus stops him from finishing off the prisoner and begins to lecture him on doing harm where none is necessary, but Ratchet is agitated, believing they should be more proactive. As the argument heats up, Ratchet even manages to antagonize Arcee by bringing up Cliffjumper, and Prime decides to confine Ratchet to base. Though Ratchet appears to go calmly through the Ground Bridge, moments later, he charges back out, flattening Bulkhead and racing off. Prime's team returns to base, but is unable to get a fix on Ratchet's signal.

In a Decepticon energon mine, Breakdown is chatting with a miner when Ratchet walks into the cavern. Elsewhere, Megatron shouts at Knock Out for not finding a new energon source, but they're interrupted by Ratchet dropping Breakdown on the floor. Megatron scoffs at the newcomer, until a punch from Ratchet sends him flying. However, Megatron is made of sterner stuff, and he gives Ratchet a savage injury, telling Knock Out to take a sample of the resultant leaking fluids so they can find out how Ratchet got so amped up.

On the bright side, as the synthetic energon drains out, Ratchet is rendered visible to the sensors in the Autobot base, and Optimus, Arcee and Bulkhead use the Ground Bridge to attack the mine.

Knock Out completes taking his sample and moves in to finish Ratchet off with his circular saw. When the sound of approaching fighting distracts the Decepticon, Ratchet takes the opportunity to fight back, resulting in Knock Out's saw getting stuck in the wall. Ratchet promptly grabs the synthetic energon sample and smashes it. Knock Out is outraged, but once more has to retreat as the other Autobots arrive.

Ratchet is hooked up to a drip back at base, and he apologizes for his behaviour. Optimus points out the new supply of energon they got from the mine, and Ratchet promises to do more testing on the synthetic stuff before using it on Autobots again. Optimus is just thankful they destroyed Knock Out's sample, unaware of the fact that back at the mine, Knock Out has found a single drop of synthetic energon.

Tropes:
"Ratchet: I need to be at the top of my game..."
 * Berserk Button: Ratchet triggers Arcee's button when he brought up Cliffjumper. She had to restrained by Bulkhead.
 * Dirty Old Man: Ratchet actually hits on Arcee and winks at her.
 * G-Rated Drug: The synthetic energon is a clear stand-in for steroids.

""You know your problem, Optimus? For such a big, strong bot, you're soft. You didn't pound Megatron into scrap when you had the chance! Many chances, in fact!""
 * "The Reason You Suck" Speech: Ratchet really lets Optimus have it - blaming him for the Autobots "squandering their resources," what happened to Cliffjumper and not being proactive enough against the Decepticons. The last part probably stings him the most:


 * Professor Guinea Pig: Ratchet was so eager to help...
 * Took a Level In Jerkass: The synthetic energon improves Ratchet's physical abilities, but also "impairs his judgment" - making him increasingly obnoxious and aggressive towards his own team.
 * What the Hell, Hero?: Ratchet was going to torture a miner Decepticon, if Optimus didn't stop him.
