Complete Monster: The Joker, starting with his Moral Event Horizon. After finding out Harley was secretly helping the Green Goblin, the Joker shoots her. Later, after tricking the heroes into thinking The Punisher shot him, the Joker leads Harley away as they try to escape. The Joker assures Harley he wasn't going to leave her there to die...and then hits her to the ground, saying this is a much better spot. When he comes back from the dead in Rorsarch and Deadpool 2, he kills a mook who sold him out in a very painful and thankfully offscreen manner, then shoots Rorsarch.
The local version of the Green Goblin is just hilarious to watch.
Ever since his introduction, Deadpool has become just as popular, maybe even moreso.
Lars M. Dusseldorf is probably a truer version of this trope, as since their popularity became apparent Deadpool and Gobby have been pushed increasingly to the fore, whereas we can be assured that Lars is not going to take centre stage. But he is very, very awesome.
"Funny Aneurysm" Moment: After Spider-Man wakes up from a dream in which his incarnations from both of his movie franchises feud, he tells Batman that The Amazing Spider-Man might outgross The Dark Knight Rises. Even though Spidey's movie made enough money for the studio to greenlight a sequel, it still made about $200 million less than Dark Knight Rises.
Genius Bonus: Deadpool's Trade Snark during the "Rorschach and Deadpool" song (Copy and I'll suuuuuuuue) is made all the funnier when you realise that the backing track (And the melody based off said backing track) is based on "West Precinct Medium", a piece of royalty-free music from Apple's iLife bundle included with most Apple products, which under most circumstances are perfectly legal to use in videos one is making money off of.
So the trailer for the 2011 DC Universe Online premiered and in it a future Lex Luthor traveled back in time to warn the heroes that the world would be destroyed if they didn't stop him. Sound familiar? Hilariously enough, RandomGuy lampshaded this in a BlogTV chat:
"Green Lantern vs. The Critics" ended with Deadpool going through the Reynolds-ing as he now has Ryan Reynolds to himself. This becomes much funnier now that Ryan Reynolds has been cast as Conner MacLeod for the upcoming reboot.
Said gag ends with Cap saying "Avengers Assemble... a Human Centipede!" Come Agents of S.H.I.E.L.D., "Centipede" is now the name for what can give regular humans superpowers.
Another part of this video was Nick Fury saying In Ways to Screw Up the Avengers Movie "I'm here to talk to you about the Avenger Initative...Howard." And now he's appeared in the after credit scene of Guardians of the Galaxy.
Back in April of 2008, Happy Hour 1 was released, in which Logan was gloating about how he had an award-winning director, and thus was going to have a great movie. Hulk proceeded to point out this was no guarantee. X-Men Origins: Wolverine came out a year later, and it is remembered for being one of the worst superhero movies to date.
In a video where Adam West's Batman and Howard the Duck face off, Batman makes a comment about Marvel Studios preferring talking raccoons to talking ducks. In Guardians of the Galaxy the studio has it both ways
During Hal Jordan and Magneto's debate, Hal states that "[Green Lantern] is the first of a trilogy while [X-Men First Class] is running on the fumes of a fifth." Guess which film ended up starting a trilogy?
In the very first episode—March 2007—Superman said DC "asked a few writers to think about the possibility of maybe what it might take to theoretically make a Justice Jeague movie in the next ten years or possibly more perhaps." The tentative release date for the Justice League movie is October 2017, ten years later.
Speaking of, RandomGuy made a parody of The Avengers by replacing the characters with the Justice League. Sure enough, Joss Whedon took over rewrites and reshoots for Justice League.
Ho Yay: Mostly on Deadpool's part towards Ryan Reynolds, and Rorschach. In the latter's case, Deadpool shoots an old man to steal his fedora (and hug it) because it reminds him of Rorshach.

Moral Event Horizon: The Joker, naturally, crosses this in the final episode of "Happy Hour". After finding out Harley was secretly helping the Green Goblin, the Joker shoots her. Later, after tricking the heroes into thinking The Punisher killed him, the Joker leads Harley away as they try to escape. The Joker assures Harley he wasn't going to leave her there to die...and then tosses her aside, saying this is a much better spot.
Pacing Problems: A huge amount of season 3 has been spent just explaining the plot.
Selfish Good: Depending on the tone of the vid Iron Man was in. As he puts it, people kind of expect him to be a media whore.
Shallow Parody: The movie trailer parodies sometimes fall into this, usually by copying the trailer and adding jokes based on which character replaced whom.
