Welcome to the team. Just be prepared: sometimes in the Wreckers, your first day is your last.
And I Must Scream: Trapped in a coma at the end of the series, though he is implied to have gotten better.
Angst Coma: Goes into one after his mutilation at the hands of Overlord. Despite being completely repaired and rebuilt, he suffers from "zero point" a seemingly incurable affliction that prevents his spark from powering his body. Rung suggests that Roadbuster read Ironfist's stories of the Wrecker's past exploits to him, and it ultimately seems to work when Springer's painful memories of Pova resurface.
BFG: Ironfist supplies him with a huge rotary Gatling-style weapon to use against Overlord. It doesn't even slow Overlord down. At least until Ironfist detonates the thousands of deterrence chips it embedded in him...
Badass Bookworm: Has an encyclopaedic knowledge of the Wreckers, to the extent that he knows more about some of their members than they do.
Been There, Shaped History: Designed Optimus Prime's signature rifle while serving as Wheeljack's apprentice. Optimus never knew his name.
Beware the Nice Ones: Possibly one of the only Wreckers ever to be, all in all, a pretty Nice Guy. That being said, there's a reason use of most of his inventions constitutes a war crime, and he is more than capable of throwing together obscenely lethal weaponry to even out his relative lack of combat power. Overlord finds this out the hard way.
He didn't take being set up to die in a "lab accident" kindly either, and throws together an awesome Thanatos Gambit to ensure Skyfall goes down hard.
You Killed My Friends: Changes his mind about not joining after hearing that Kup will be on the team. A while back, Kup killed Guzzle's friends after being driven insane by the radioisotope Ore-8, and Guzzle's been wanting to confront him about it. He never gets a chance.
Catch Phrase: Doesn't have one yet. We see him trying to come up with one, and failing miserably.
Adaptational Badass: In most media, Broadside is mostly known for being "that one guy that turns into a seasick aircraft carrier and Acrophobic Jet." Here, he's not only one of the longest serving Wrecker members, he's one of the few that actually survives his tenure.
Badass Grandpa: He's been around since the events of Megatron: Origin.
Skewed Priorities: Garrus-9, the best prison the Autobots have, run by one of their best soldiers, and an immense asset to the war effort. Why does Prowl send them in there, after two years of waiting? To get the data on the Aequitas trials.
Best exemplified by his name for the mission: Operation Retrieval.
Talking the Monster to Death: One almost feels sorry for Violator. Captured by the Autobots, he's forced to endure Prowl listing every single crime he committed, and as his name suggests there's a lot of those. And Prowl doesn't just list the crimes, he lists the parts of the Tyrest Accord that Violator has broken, for two and a half days. Finally, Violator just decides to kill himself.
Uriah Gambit: Implied. Sending the Wreckers to Garrus-9 may have been Prowl's way of assuring that Springer and his men are no longer a problem.
By-the-Book Cop: Why he won't go to Garrus-9 with the Wreckers, because his job can't condone the things they usually do.
Major Injury Underreaction: When Impactor puts a hook through his eye, he just pops a Slasher Smile before stomping him into the ground, and then there's his reaction to Perceptor shooting his hand off...
Subverted when Ironfist blows his exterior plating off; though it's more because he knows he can't face down Megatron in such a compromised state than a reaction to the pain.
Villainous Breakdown: His composure slips when Ironfist reduces him to a burning skeleton, saying that he won't be able to face Megatron in such a state. Verity then decides to let the other shoe fall, telling him that Megatron a) never cared enough to track Overlord down, and b) is kind of dead, forever robbing him of the opportunity to best him. It works.
Verity: Oh, man, this is PERFECT! You can't accept that he never gave chase! You lived your life thinking about him every day, and he died forgetting all about you!
Overlord:But... But he owes me! He owes me.
Let's just say I had an epiphany. I watched too many people make choices and realized I had one of my own to make.
Villainous Breakdown: When Snare leads Kup and Guzzle to his lab, his response is to start yelling "Traitor!" over and over right before shooting him in the face. Springer does a number on Stalker's own head before he can finish the job, though.
Shockwave: You've had control of the last resort for eleven months, three weeks, four days, fifteen hours, fifty-five minutes and eleven seconds... and only now do you choose to reunite me with my body?
