Thunderbolts/YMMV

Examples from the original series:

Magnificent Bastard: Zemo, Moonstone.
Unfortunate Implication: Name the Token Black Guy "Charcoal", real smart there...

Ass Pull / Deus Ex Machina: The ending of "Caged Angels".
Rescued from the Scrappy Heap: Jack Flag, a character previously most notable for his red, white, and blue hair, saves a woman from a group of rapists even though he knows doing so will result in imprisonment in an alternate dimensional prison (which it does). He's later recruited for the Guardians of the Galaxy.

Ass Pull: Because Mr. X has the ability to read people's minds and predict every move they make, excuses were constantly made for why he just got beaten, and they mostly came across as these.
Complete Monster: The others joined because of money, respect, infiltration, but Mr. X joined for the killing.
Informed Ability: Their usefullness. The black-ops Bolts have a very low success rate. It's a wonder why Norman bothers with them at all.
Nausea Fuel: The Ghost's lack of hygiene is sickening; after being hit with a sonic bomb by Deadpool, he threw up in his helmet and never cleaned it out.
Paranoia Fuel: The Ghost is clinically paranoid; he doesn't eat anything that he hasn't prepared himself, he welded the door to his room shut so the only way in or out is with his suit, he always triple-checks equipment before a mission...
Put on a Bus: The second Black Widow, who actually got on the bus before the series even started and was just about to get off when the series ended.

Crack Pairing: Moonstone and Man-Thing.
Crazy Awesome: Not so much a character but a concept. Using Man-Thing as the team transport. All thought up by resident mad genius Hank Pym.
- The Raft's last line of defense against a water escape? Huge bio-cybernetic jellyfish. Also implied to have been created by Pym.
- Luke Cage makes his introduction by jumping out of a plane and slamming to a landing. Ladies and gentlemen, your new leader...
They Changed It, Now It Sucks: The general reaction to Songbird's redesign.
- Although her look is gradually shifting to her old design (that is, she's letting her hair grow long).
