The entire movie is a morphine dream of Dr. Vivian Bearing
Dean Hardscrabble will be the main antagonist.
The movie will feature Randall's Start of DarknessYou know Randall? That slimy, conniving Jerkass of a scarer? Well, here he's depicted as a kind, smiling nerd who bakes cupcakes! Clearly, something happened here...
Mike and Sulley did meet in grade school...They just don't recognize each other when they met again for the first time in years, I mean you can't remember all of your classmates over the years. But they might remember each other as the movie goes on so who knows...
Mike will be the protagonist in this one.The first one focused on Sulley, and the trailers seem to have an increased focus on Mike.
Sulley will be shown to be good with (monster) kids, as foreshadowing to his relationship with Boo.
Some monster will say 'You were Jealous of me in the fourth grade'.proving that it is a monster expression, or maybe meme.
The film will have shades of Ho Yay between Mike and Sulley.They seem rather friendly when it comes to their fierce competition for who's the smartest or scariest. There are some clips in the trailers that show that Sulley does actually care about Mike, but probably doesn't want to show it.
Randall will have been evil all along.Let's be honest, Pixar of all groups should know better than to encourage the "cute=good ugly=evil" philosophy among fandom, a notoriously shallow and overly forgiving bunch. We don't need them turning Randall into (even more of) a Draco in Leather Pants, with even more reasons for them to forgive his being a cheating, lying, assholish kidnapper and almost-murderer. Instead, the film will show him having formerly been a chameleon in a different sense, trying to blend in with society to throw suspicion off himself and giving it up partway through the film.
Johnny Worthington is going to be the Starter VillainGoing by the movie clip when we first see the guys at Roar Omega Roar, the president Johnny would be the obvious candidate for the film's Big Bad, as even with only a few lines he already exhibits the kind of stuck up Smug Snake behavior that comes from the stereotype of an old money college frat boy antagonist seen in these type of movies. However, as the movie will go on, we'll actually see him having natural talent in scaring, combining genius level expertise of scaring theory that rivals Mike has with the actual ability to be scary like Sully. Despite him being a snooty Jerk Ass, he will eventually gain tremendous respect for Mike and Sully as they help propel Oozma Kappa to glory, as well as respect the friendship the two monsters have, as the audience will see that, while Worthington does consider his fellow ROR brothers as friends, he doesn't consider them to be Nakama-level like with OK. Plus, this will serve another purpose: With Worthington being the main focus for Mike and Sully to beat, the real antagonist is left to do their own device until The Reveal, not only to the heroes but possibly to the audience as well.
The Scare Pig is suppose to be a family friendly version of the Devil.
Boo will make a cameo at the end.Either the gang will check a door and overhear her parents talking about trying to have a kid or Boo herself will show up as a baby noticing the unusual behavior of her closet and peek in, explaining why she's seemingly more comfortable with monsters in MI.
Becoming a Scarer requires a license, not a degree.Before a monster can be authorized to enter the toxic human world and scare a child and, therefore, be employed as a Scarer, or operate the equipment on the Scare Floor like doors and canisters like the Assistants do, they have to pass an exam to become licensed. Attending the classes necessary to get a degree in Scaring is a good way to learn what's necessary to pass the licensing exam, but not required. Hence, after several years of relevant work experience and training, Mike and Sully were able to become licensed/certified to work on the Scare Floor despite never gaining degrees in Scaring.
Screams from adults generate more power, but the amount of time to get them scream is the reason why screams of children are preferredAs seen in the climax, Sulley (Through Mike's knowledge and on-the-fly-planning) successfully scares a group of adults. So much so that the scream canisters and the door explode from the power. This could insinuate that the scream of an adult generates more power. However, because adults are explained in the movie to be harder to scare, the amount of time to try to do what Mike did isn't practical in a job that requires scream energy every few seconds.
A lot of monster colleges are sponsored primarily by one of the big Scream energy companies.Not only does Monsters University have a very similar logo to Monsters, Inc., but notice their rival school, Fear Tech. When they vandalized the MU page they covered it in red, orange, and black. Looking at the scarer cards in the credits, some of the characters went on to work at Fear Co., whose logo is, guess what, red and black. Between the colors and the names, it doesn't seem unlikely for there to be a very strong connection between the Scream corporations and the colleges that train their scarers.
The Scare Floors at Monsters, Inc. are separated by gender.All the Scarers and Assistants seen with Mike and Sully on their Scare Floor in the first movie are male, but the gender ratio of students majoring in Scaring at Monsters University seems 1:1 or close. Presumably, this arrangement is done because, whenever there's a 23-19, someone needs to be decontaminated.
Mike is an immigrant who was born in another countryIn the stadium during what seems to be the national anthem, Mike is not putting his hand over his heart like everyone else, but is standing at attention, his hand and hat down behind his back. It also helps that Mike's last name is of Polish origin. Presumably, Mike was born in some sort of Polish country and came to this country when he was very very young. Also, since he possibly is from a family of immigrants, typically he'd be pushed to have high academic performance, another reason why he could have wanted to be become a Scarer.
Celia and the girls of PNK are their universe's alternative subculture at best and hideous at worstIn a world where a monster must be scary above all else and spraying yourself smellier with 'odorant' happen, it would logically follow that things we would find nice and conventional here, like Cute Monster Girls and pink, would be considered weird or ugly there.
Art went to jail because of drugs!He acts pretty high and kind of acts like a hippie ... especially when he gives his journal. He has probably cut off the drugs since then though. OR he was a part of a club and he got sold out by someone for doing drugs.
Related to the above, Art is a vague Expy of Gamzee MakaraActs kind of like a stoner, would rather space out staring at a butterfly, is purple, spaces out and says weird things that confuse the hell out of people, proves he can be scary when he decides to get serious...he's like a monster version of Pre-Sober!Gamzee.
Art probably touched something he wasn't supposed to ... like a fragile artifact or something.Remember when he wanted to touch the poison urchins? Well ... he probably touched something at a museum and broke everything, causing him to go to jail.
Art never was in jail.He just always wanted to say that.
Sherri isn't nearly as clueless as she seems.She's just trolling her son like it's going out of style.
Sully shook Randall off of the wall on purpose.We already know that Sully was willing to cheat to win the contest. Randall either suspects this, or the Dean told him after Sully admitted to cheating, furthering his resentment of Sully.
The reason the other Oozma Kappa didn't appear in the first film.They were in jail. Art did some sort of thing similar to what got him arrested beforehand ("I can't go back to jail!"), and Don, Squishy, and the Perry brothers got thrown in with him due to being involved in the crime somehow.
Oozma Kappa got jobs at Monsters Inc. after the end of the movie.Think about it. Squishy, Art, Don, and Terri and Terry aren't usually very intimidating; they're just too friendly-looking. Difficult if you're trying to scare kids...but perfect if you want to make them laugh.
Mail Tampering is not punishable by lifelong banishment.
The Librarian goofed up and was banishedShe was sent to a large lake in the human world. At first it was alright; after all, she was alone, it was quiet and it was peaceful. But then, construction started to occur on the hill beside the lake and then a road appeared, with many loud cars driving by. The Librarian would respond to all of this by surfacing and trying to "shhh" people. They would see her, but not hear her. And when they saw her, they flipped out and realized that a monster was in the lake! So tourists flocked to the lake to catch a glimpse, and the Librarian quickly learned that the public had given her a new name: Nessie.
Randy and Randall aren't the same person.They're twins, with Randall being of the evil variety. This is why the sudden turn to being a Jerkass can come off as so sudden, and why Mike and Randy never interact after the one scene (also works to explain why Mike and Randall don't mention anything from this movie in the original movie). The last time we see Randy is a bit after he joins ROR; after that it's Randall. Either they just decided they liked Randall better, or there was a mix up and they meant to recruit him from the beginning. Also, there's a storybook for the first movie that shows Randall's nephew in the daycare at Monsters Inc., and the kid looks exactly like him aside from coloring and having less things on his head, implying a sibling who works at the company and looks a lot like him. It's unlikely to be canon, but it's still worth noting.
