Marvel Ultimate Alliance/YMMV

"Deadpool: I can take down any of those goody-two-shoes wimps!
 * Better Than Canon - The second game's events to Civil War.
 * Broken Base - Players are hotly debating which of the two games is the better one.
 * Crowning Moment of Funny - The Hulk-Ku audio, Hulk is both funny and adorable.
 * The Aristocrats - Hulk's take on the vile joke is actually one of the tamest versions of it.
 * Deadpool interrupting the credits in MUA 2 and arguing with one of the game's designers on why he wasn't the strongest character in the game.

Designer: The Hulk?

Deadpool: Okay, maybe not him, bu-

Designer: The Thing?

Deadpool: Sure! If he had a cold....

Designer: Thor?!

Deadpool: Look Poindexter..."


 * Deadpool's simulation mission in the original has him claiming his origin is a mixture of Storm, the Hulk, and Thor's, and then further going on to infuriate Arcade by enjoying being in Murderworld. He even mentions in the main game that the only letdown of being there was that he did not get a T-shirt (while talking to Vision in the Sanctum Sanctorum).
 * Deadpool's unique conversations in MUA1 especially his talk with the Ancient One.
 * Nanite-controlled inmates beating the crap out of Penance, censored by the screen cutting to black so we only hear it. Your mileage may vary.
 * Hell, Penance in general. Though Your Mileage May Vary.
 * In the first game, performing combos using two characters causes a the game to 'name' the attack using attributes from both characters, for instance, Spider-Man/Human Torch might be "Flaming Web" or "Web Of Fire". Cue this troper's Nick Fury and Silver Surfer using the "Furious Fury" combo.
 * Same troper, here. Human Torch + Ghost Rider = Fiery Fire.
 * Deadpan Snarker - Spidey, as usual.
 * Deadpool, Iceman, Cage and Human Torch get in on the action too.
 * In MUA 2 you get a team bonus for putting Iceman, Spider-Man, Deadpool, The Thing or Human Torch in a team together called "Shut Up Already".
 * Ensemble Darkhorse: Deadpool. And he knows it.
 * Can he really be considered a darkhorse when, as the game was being released, the character had more books being released in one month than Spider-Man, who's main solo book is published three times a month?
 * Hilarious in Hindsight -  in the first game are either this or Fridge Horror once you find out who the Big Bad of the sequel is.
 * Nightmare Fuel - In the second game the Pro-Registration side is using mind control to control villains and force them to hunt heroes for them. During one of the missions you can find a audio clip of Reed Richards casually explaining the device to what's presumably a room full of young scientists, while the victims villains, who actually volunteered to join their side (albeit presumably for selfish reasons), fruitlessly scream in terror while they're forcibly injected with mind suppressing nanites and their minds are subjugated in the background. It's somewhat more terrifying than it sounds. Later, the playable villain characters talk hatefully about how it felt to and agree to join, no-strings attached, if only to make sure that that sort of thing can never happen to them again. It takes a lot to make Reed Richards the most terrifying character in a game that includes characters like Venom and the Green Goblin, who you instead feel sorry for, but there you go.
 * I dare you not to feel a little unpleasant hearing Venom's breathing slowing as he's sedated. And then again maybe 10 seconds later when an unidentified female villain is brought in to be injected, all the while screaming for the S.H.I.E.L.D. personnel: "No! Get away from me! No!"
 * Tier Induced Scrappy - Elektra and Blade in the first game, despite being feature on the box art. Not surprisingly, they are not playable at all in the sequel(save for Blade in the PS 2, PSP, and Wii versions).
 * Unfortunate Implications: In the Wii version of the second game, you have to stop a non-super powered prison riot. All the prisoners you fight are black. Also, most of the infected  either act like savages panthers or use bows and axes. You would think that the country that's miles better than any other in technology would have the royal guards using high-tech guns (which you've probably seen in the comics).
