Abhorrent Admirer: Hal towards Roxanne, at least initially. He's inappropriate and awkward enough with his advances to make Roxanne very uncomfortable around him. And then he gets superpowers, which does not help with this.
Hal: If I were Metro Man, Megamind wouldn't be kidnapping you all the time. Roxanne: That's sweet, Hal. Hal: And I'd be watching you, like a dingo watches a human baby! ... Okay, that sounded a little creepy... Roxanne: A little bit, yeah.
It's Played for Laughs, but when taken at face value, it becomes even more creepy, especially knowing what happens later.
Ac CENT Upon The Wrong Syl LA Ble: Megamind pronounces many words in a quirky way (presumably having learned them from reading as opposed to interaction with his classmates) especially "Metro City" (he pronounces it "Metrocity", which sounds like "atrocity"). This comes back to bite him.
Ollo! - Hello
Shool - School (although this could also be a "shul" reference in the sense of a synagogue and the education therein).
RevAHnge - Revenge
MelONkuhlee - Melancholy
Spee-ider - Spider, in a fit of serendipity.
Mooldings - mouldings
In "The Button of Doom": Zherage - Garage; Ra BAHT - Robot
Adorable Evil Minion: Minion has the whole 'alien piranha in a gorilla-themed mecha death suit' thing going on, but is otherwise quite sweet and lovely. Also applies to the Brain Bots, which when not obeying Megamind's every whim tend to act like puppies.
Adorkable: Megamind, whether he's in his Bernard disguise or out of it.
Adult Fear: Metro Man juggling babies and tossing them to their parents can trigger this. Sure, they don't seem to be in distress and make it out fine, but try picturing how parents in real life would react to this happening.
Not surprising, as he was raised on Earth, and though he knows he isn't one, essentially thinks of himself as a human.
Alliterative Name: Megamind. Metro Man later Music Man. Roxanne Ritchi. (Minion deserves an honorable mention for fitting the "M" theme.)
All Robots Are Dogs: The Brain-bots act like a big group of puppies when not carrying out an evil plan—they swarm over to Megamind at the start while Minion says they missed him, play fetch with wrenches and Megamind frequently refers to himself as "Daddy" regarding them (much like most pet-owners do).
The Spider-bot in "The Button of Doom" short whimpers like a dog when Megamind tells Minion that he can't keep it, too. Minion even calls to it exactly like one.
This is however slightly undermined by the revelation that he also has Minnie Riperton's "Loving You" on his playlist.
Metro Man also does this to a lesser extent; he invokes a lot of Elvis imagery during his introductory scene. The fringe on his costume, the pompadour hairstyle, he even busts a few Elvis-like moves while a remix of "A Little Less Conversation" plays. There's also something familiar about his death.
Beware the Superman: Titan is probably the poster boy for this trope. The contrast between him and Metro Man is stark.
Be Yourself: The rare non-Anvilicious version of this Aesop. Megamind learns that his constant defeat, as pointed out by Roxanne, has turned him into a determinator who is unafraid of losing.
Big Bad: While he's still very hammy as a villain and ends up reconsidering things by the midpoint of the film, Megamind did set up the dominoes that caused a great deal of damage to Metro City, but it's Titan that ultimately decides to collide against those same dominoes for a very petty, shallow reason.
Big Damn Heroes: Several times. Metro Man tries to do this at the beginning of the movie. Too bad Megamind tricked him into going to the wrong place.
Happens twice at the end, once by Minion disguised as Megamind, and another time by Megamind disguised as Metro Man.
After his victory against Metro Man, Megamind walks down the streets of Metro City, heralded by his brain bots doing a light show, set to "Highway to Hell."
The crowner is at the end, where he uses his brain bots to set up a giant holograph of his head, then walking out the tongue. It sounds weird, but it's really quite cool, and incredibly hammy.
Bilingual Bonus: If we count flower language there is also the bouquet Megamind brings to the Metro Man Museum; the most common meaning you will find for yellow roses is "friendship" and another is "an apology". Most bouquets don't contain dynamite, however.
Bizarre Alien Biology: Wait, how the hell could the fish Minion actually smell that Megamind was wearing cologne? Fish can smell by moving water through their nares, but if Minion were an Earth fish, it would only make sense that Minion could smell the cologne if Megamind were in the water with him.
He also starts coughing from dust in the air. Despite, you know, being sealed into a water-filled glass dome.
If we really wanted to get nitpickey, what are the chances that both Megamind and Metro Man could live on earth?
The interesting thing is, it's boring to nobody except him. And it makes sense. He says himself that at the part where he fakes his own death that he's just "going through the motions." Megamind tries to take over the city, Metro Man defeats him. Day in and day out, (presumably) every single day. And the city keeps expecting him to do this for goodness-knows-how-long. He wants to do something else, darn it!
A lesser example could be the Warden taunting Megamind at the beginning of the movie. The guy was practically setting himself up for Megamind to pull a dirty trick on him!
But He Sounds Handsome: While Megamind is "fighting Bernard" and switching between his illusions to maintain the disguise in front of Roxanne, fake Bernard yells stuff about how strong, handsome and tough Megamind is.
Megamind: (as Bernard) I tried my best, but he's too fantastic.
Butt Monkey: Megamind himself. He is a comedy villain, so it is part of the job description.
Can't Believe I Said That: When Hal tries to get Roxie to go to his 'off the hook' party he lists the things he's arranged, including a bouncy house and a wedding photographer - you know just in case they do anything they want to keep forever... as a memory... When Roxie passes Hal berates himself for mentioning the bouncy house, because "Girls don't like bouncy houses, they like clowns!"
Hal: Roxie, if I was Metro Man, I'd watch you like a dingo watches a human baby. Wait… (Also counts as Foreshadowing.)
Captain Ersatz: The main cast are based upon characters from the Superman comics. Megamind is a mixture of Brainiac and Lex Luthor (with Superman's origin), and by the end of Button of Doom has developed Batman-like characteristics, Metro Man is Superman himself, and Roxanne Ritchi is Lois Lane. Hal Stewart is Jimmy Olsen with the caveat that he has always hated Superman, whereas his name is a mash-up of Green Lantern's Hal Jordan and John Stewart and when he becomes Titan, he takes on aspects of Superboy-Prime.
Cardboard Prison: Megamind is imprisoned there once in a while, serving out his 88 consecutive life sentences, only to waltz his way out and continue with his evil plans.
Chair Reveal: Megamind invokes this during his kidnapping of Roxanne.
Changed My Mind, Kid: Invoked, Metro Man apparently returns to the fight after claiming he wouldn't return to being a hero because he knew a new hero would step into his place. After scaring Titan silly with Metro Man's persona, Roxanne discovered that Metro Man was actually Megamind using his holographic disguise and gadgets to imitate superpowers. Metro Man never actually returns to save the day and Megamind has finally made the transition from villain to hero. Unfortunately, Titan figures it out as well....
Clasp Your Hands If You Deceive: Megamind plays up the stereotypical "villain" body language for all it's worth. Played with at the opening of the Megamind Museum, when a boy in the crowd apes Megamind's villainous hand-clasping pose because Megamind is his hero.
Classic Villain: Megamind combines many iconic traits of comic book villains.
Cloudcuckoolander: When he's free from having to be the perfect superhero, Metro Man apparently has a bit of this in his character, judging from his decision to call himself 'Music Man' so that he can keep his logo. Roxanne and Megamind are understandably nonplussed.
Completely Missing the Point: Titan only wanted to be a superhero to impress Roxie. He has no interest in being a do-gooder. Earlier, he also asked Roxie to come over to his house for a date where he had arranged for, among other things, a bouncy castle and "a wedding photographer"...just in case Roxie decided to marry him then and there. Roxie is understandably unnerved and declines. Hal slaps himself and berates himself for being as stupid as to get...the bouncy castle, because everyone knows girls love clowns.
Also, this moment when investigating the deceased Metro Man's apparently long-abandoned stronghold:
Roxanne: Look! This glass has ice in it! Megamind: Yes, that's what happens when water gets cold.
Megamind, as "Space Dad", dubs Hal as Titan for his superhero name, invoking enormous deities of incredible power note and showing him his spandex costume. Instead, he hears it as "Tighten", as in "to squeeze". This is the name he winds up carving into Metro City during his rampage.
And when Hal gets angry once he finds out that Space Dad is really Megamind (while Space Mom is actually Minion), Hal shows what he thinks about the whole backstory "Space Dad" made up for him....
Hal:And this is for Space Mom! You lied to her!!!
Complexity Addiction: Megamind, as with all good Card Carrying Villains, seems to prefer devising and enacting incredibly convoluted plans to achieve his goals, and likes to mind-map them by stringing up pieces of paper in complex patterns. For example, his plan for what to do with his life after defeating his arch-nemesis involves securing his arch-nemesis' dandruff, distilling all the superpowered qualities out of it, firing them into someone, disguising himself as a space-mentor, training the person to become a superhero, and then fighting him. As opposed to, say, taking up yoga.
Conspicuous Trenchcoat: Megamind's Brain Bots hide under a trench coat and fedora in a crowd during the opening. It is bookended in the conclusion when we see Metro Man using the same tactic.
Contractual Genre Blindness: Megamind seems to cheerfully accept the fact that defeat is inevitable in his part of the conflict with Metro Man and operates accordingly. At the beginning, he even begins winding up his current plan under the assumption that it's failed without actually noticing that Metro Man is having a surprising amount of difficulty breaking out of his most recent trap. When Megamind actually ends up winning, he's as astonished as everyone else.
Titan picks up an entire skyscraper and flings it at Megamind at one point, crushing several other buildings and carelessly knocking it into another as he turned it. If it wasn't made explicit that the city had been largely evacuated by this point, thus making these allConveniently Empty Buildings, we'd have to assume this movie's body count probably hit quadruple digits.
Curse Cut Short: At one point, Megamind and Minion are walking to "Highway to Hell" by AC/DC, which gets cut off by another song right as they get to the first instance of 'Hell' in the song. Then it's subverted when Minion fiddles with the boombox's controls, trying to turn it off, and it switches back to the song and the word 'Hell' is almost the only word heard before switching away again.
Damsel in Distress: Roxanne is a parody of this; she is so used to being kidnapped and rescued that she is not fazed by it anymore. However, she really ends up being in danger by the end.
Roxanne: Can one of you punch my frequent kidnappings card? Megamind: You of all people know we discontinued that promotion.
Dark Is Not Evil: Megamind evolves into this by the end of the film. The major theme of The Button of Doom is him deciding that Dark Is Evil and changing his style and methods to Light is Good. It doesn't stick.
Deadpan Snarker: Roxanne Ritchi. Helps her get through each kidnapping by the hands of Megamind until Metro Man comes to rescue her, as usual, and she can go on with the rest of her day.
Death Ray: How Megamind supposedly kills Metro Man.
Deconstruction: The movie examines the relationship there would have to be between Hero and Villain, and that a Superhero Origin can just as easily apply to a villain. It also looks at the classic Silver Age story of Superman's Pal, Jimmy Olsen, getting powers. Mostly, it deconstructs The Bad Guy Wins plot, as the villain no longer has what drives him after the death of his nemesis.
Determinator: Being so fully invested in the "proper" dance between heroes and villains means that Megamind never thought his plans had a chance of succeeding anyway. So he's been losing to Metro Man repeatedly over the course of his life, 100% failure rating... yet he's never let that be an excuse to give up, but instead let it encourage him to get more creative. Near the end, Roxanne reminds him of this, saying it's his best quality - and convincing him to wade into a hopeless situation once again.
"He would win some... I would almost win others...."
Lampshaded when Tighten mockingly points out that no matter whether Megamind fights for good or evil, he still always loses:
Megamind: There's a benefit to losing. You get to learn from your mistakes.
Disappeared Dad: In a weird reversal, Metro Man's parents are hinted to be very uninterested (his father doesn't even look up from his newspaper when he's flying as a baby), while Megamind's "parents" (the prison inmates) treat him warmly like family, despite teaching him Family Unfriendly Aesops.
Disney Death: Minion. At the end of the movie, his fishbowl is broken. He gasps for air in a sequence similar to King Harold in Shrek the Third, and then "dies". However, Megamind throws him into a nearby fountain, reviving him. He apparently did it for the sake of drama.
The Ditz: Hal strays into this territory at times. Honestly, his idea of romance is something you'd find in a kid's birthday party.
Double Take: When it looks like Metro Man has survived the explosion at the observatory and is coming to rescue Roxanne, both Megamind and Minion have a moment where they sigh in relief that he's alright. Then, they remember that this means he's also coming to arrest them.
Easily Forgiven: Megamind had committed enough crimes to merit 88 life sentences, but he saves the city from Titan, and he is the new official hero, beloved by all.
Not to mention, presumably Megamind and Roxie are the only ones that know that Metro Man isn't dead, but the people don't know that. To them Megamind killed their beloved hero for good. Oh well, guess Megamind is just that loveable.
Could have been mended with a single scene showing a judge sentencing Megamind to lifetime community service, picking up litter and saving Metro City from utter annihilation.
Well, the guy had just singlehandedly eliminated two superpowered beings, and the regular police and military were virtually powerless to stop him. He also pretty much rebuilt the city using the Brain Bots. It may be that the people knew that he could do whatever the hell he wanted with them anyway, so if he wanted to be their hero, best not to argue.
Faster-Than-Light Travel: How fast is Metro Man? In the nanosecond between the concentrated solar blast and his "death", he gets a skeleton from a "nearby" nursing school, puts his cape on it, comes back to the observatory to lauch the skeleton, and then gets away.
It's better than that. He goes into Megamind's true location, is about to stop him, has an epiphany, goes to clear his head, reads a few self-help books, concocts the plan to fake his death, and executes it. All within a nanosecond. Dude is FAST.
Only if he had to go further than about a mile.
He also goes to a park to fly a kite and stops by a diner for fries and milkshake.
It's much more than a nanosecond. He's gone long enough for his absence to register as a dimming/flickering on the big screen display, so in the neighborhood of 20-30 milliseconds.
Feud Episode: At one point, when Megamind is dating Roxanne while disguised as Bernard, he and Minion have a falling out and break off their lifelong friendship.
Flynning: Megamind and Titan engage in a round of this with lamp posts; it's actually intended to be harmless Flynning on Megamind's part, but it quickly becomes clear that the feeling isn't mutual.
Foil: As expected, Metro Man and Megamind are foils for each other, being complete opposites in level of superpowers, moral outlooks, and style, but yet Not So Different after all.
Let's not forget Metro Man and Titan; same powers but completely different morals.
Foreshadowing: Hal gets the Titan powers via a stray shot into his nose. Later during a fight, his head bashes through a wall and someone's chopstick goes up his left nostril. Which is where Megamind shoves the depowering gun later on.
There was this gem early on:
Hal: "Roxie, if I was Metro Man, I'd watch you like a dingo watches a human baby. Wait…"
On the topic of Hal/Titan, in the training sequence, you see him gleefully melting the face of the Megamind mannequin. Played completely for laughs at the time, but later you see that first, it shows he's more than happy to defy the standard superhero Thou Shalt Not Kill policy, and second, that he has much more of a dark side than one would give him immediate credit for.
As a child Megamind dehydrates and then rehydrates Minion, who 'plays dead' causing his boss to act concerned for him.
Titan proves that he is not weakened by copper, which is our first clue that Metro Man isn't dead.
The phrase "Game Over." First seen on Hal's shirt when he films Roxanne, then seen on a television screen when Titan goes berserk, and finally, Titan's threat to Megamind, delivered so he knows he means business.
In the scene where Hal gains Metroman's powers he's wearing a shirt that says "Bite Me" with a vampire smiley face. What happens when you get bitten by a vampire? According to a lot of versions of the myth you gain superpowers and turn evil.
Not long before he quits the superhero thing, Metro Man says in his speech to the people of Metro City, "and at the end of the day, I often ask myself: what would I do without you?"
Metro Man also is playing a banjo in front of classmates when Mega is stuck in the corner. He's always wanted to be a musician, even then.
In the scene just before Titan fights Megamind, he holds up a torn magazine with Metro Man carrying Roxanne. The top of the magazine is torn off, and he holds it up in a way that puts Megamind's head where Metro Man's originally was (with "HERO" prominent on what's left of the cover).
Also something of an Ironic Echo, given that the roles were reversed, with the replacement idea explicit, earlier.
For the Evulz: Subverted by Megamind; he is a Card-Carrying Villain, but sees his wrongdoings as a form of self-expression rather than an end unto itself. Played straight with Titan, who obviously enjoys causing mayhem with complete impunity.
Freeze-Frame Bonus: When Megamind and Metroman are bantering at the beginning of the film there are one or two frames where Metroman has disappeared from the observatory and can be seen behind Megamind. This actually leads to a continuity error when you realize that during the Time Stands Still sequence later, Megamind is clearly in a different part of his speech.
Also, the other functions of the de-gun can be seen this way. The most notable are "demoralize", "de-ath ray" and "decoupage".
Fresh Clue: Megamind and Roxanne go into Metroman's hideout and find a glass of water with ice in it, which is proof that someone was there recently. Sure enough, they turn around to find Metroman still living there.
Friendly Enemies: Megamind and Metro Man. When Megamind makes his reveal at the beginning that he had captured Roxanne in his latest ploy, Metro Man plays his part with the usual "You won't get away with this!" lines. Roxanne, as said before, is not as excited to be part of the show.
Funny Background Event: While investigating Metro Man's hideout, Roxanne and Megamind come across a glass of water and wonder about the fact that it still has ice cubes in it. Meanwhile, Metro Man — who they think is dead — comes in, notices them, and frantically tries to sneak out without being noticed. We find out a few seconds later he has Super Speed, making this an example of Rule of Funny. Alternately, he just panicked.
Roxanne: I say we go back to the evil lair, grab some ray guns, hold 'em sideways and just go all gangsta on him.
Genius Bruiser: Metro Man's flashback reveals that he is actually a pretty smart guy.
We get a tiny bit of Foreshadowing that Metro Man is smarter than he seems merely by the fact that he went to the same "special" school for gifted children that Megamind did.
Genre Savvy: Megamind and Metro Man are both really practiced at what their roles as Super Hero and Super Villain include. Megamind is happy to submit to being defeated each time he tries an "evil" scheme. He actually ends up so depressed at having defeated his arch-nemesis that he fakes an origin story for a new Super Hero to arise and defeat his "reign of terror".
The final celebration scene, when Roxanne fastens Mega's cloak around his neck, while standing in front of him. His head is bowed, possibly to express that he is in the "shyness" phase of being in love; but from his Male Gaze, he is taking advantage of the moment to stare down her cleavage.
Glamour Failure: Megamind's holo-watch allows him to look like anyone it scans beforehand. However, he, apparently, forgot to waterproof it. It also shuts off if he bumps it by accident.
Also, his eyes remain unchanged no matter who he's impersonating. This appears to be the case with anyone using the holo-watch (Minion as well)... with one exception probably used to heighten drama, because the scene would've been had a different feel if you figured it out too fast.
The Glomp: Roxanne to Megamind in the final scene.
Glowing Eyes of Doom: When Titan is about to use his eye-beams — namely, when he gets really pissed off.
Gone Horribly Wrong: Making Hal the new "hero". He initially starts off as a decent candidate for the next hero, but he slowly starts to unravel. When Megamind provokes him into a fight by taunting him with his relationship with Roxanne, everything goes downhill.
Good Colors, Evil Colors: Subverted in The Button of Doom: Megamind starts out trying to fulfill his new role as Defender by replacing his black "Villain" suit with a white outfit and bulky gadgets mimicking Metro Man's powers. But after realizing that he's better off fighting threats hisway, he settles with defending Metro City in his old suit.
Roxie starts in red, but switches to purple once she has fallen for Megamind as Bernard, and dresses in blue once she supports Megamind openly.
Megamind's eyes are green to represent his envy of Metroman.
Good Is Not Nice: As a child, Metro Man was actually a bit of a jerk to Megamind. The only reason he ended up with the nice, cushy childhood and Megamind landed in a prison is because baby Metro Man deliberately crowded Megamind's rocket off course (complete with blowing him a raspberry as he passed!). He eventually grew out of it, but Metro Man's treatment of Megamind when they were children was practically outright bullying.
Graceful Loser: Megamind. He is used to getting beaten by Metro Man and is cool with that, especially if he is always jailed in a Cardboard Prison. A cardboard prison whose population he considers his family.
Green Eyes: Megamind has them. Huge, sweet, green eyes. Whenever he uses his watch to disguise himself as someone else, his eyes are always unchanged.
Ham-to-Ham Combat/You Fight Like a Cow: Fights between Megamind and Metro Man involve a lot of this. When duking it out with Titan for the first time, Megamind tries it on his new enemy, but realizes he is too bull-headed and spiteful for this kind of duel.
Megamind: Now it's time for some witty back-and-forth banter! You go first! Titan:RAAAAAAAAAAAAAAAAAGGGGHHH! Megamind: Okay, look, I don't really know where to go with that!
Held Gaze: Twice, once between Megamind disguised as Bernard and Roxanne after Bernard has "rescued" her from Megamind, and again with Megamind and Metro Man when Roxanne and Megamind discover him alive.
Hell-Bent for Leather: Megamind is this in spades, he even claims that he wears "Custom made, baby seal leather boots".
He wears two layers of leather during his first fight with Titan.
Holding Both Sides of the Conversation: Megamind has a disguise hologram that makes him look like a normal human. At one point he's in a situation where he has to pretend to be both simultaneously. There's a "fight sequence" between the two, where Megamind ends up repeatedly switching back and forth between his normal appearance and the hologram, all the while opening and closing a door over and over to give the appearance that that two are fighting each other. Naturally, Megamind has "Bernard" giving healthy dollops of But He Sounds Handsome.
Holding Out for a Hero: The people of Metro City, to the point where it's practically a deconstruction; they're so used to relying on a hero that when the hero's no longer there, not one of them is brave enough to stand up to the villain. And then the villain gets bored with the fact that no one's standing up to him. And when someone finally kicks the villain's ass, they all flock to accept this newcomer as their 'hero' without actually stopping to consider whether he actually is a hero, and not a worse villain. And of course, the whole mess started in the first place because the hero was so sick of everyone expecting him to solve all their problems that he just gave up.
Holographic Disguise: The holo-watch Megamind first uses to make the prison warden look like him so the guards will open his cell, then make himself look like the warden to escape, and later impersonate Bernard to date Roxy and pose as Titan's "space-dad".
Hope Spot: Metro Man swooping in to save Roxanne. It is just a caped skeleton propelled by the explosion.
For the civilians, Titan defeats Megamind, but then he says that they aren't free, just "under new management".
How We Got Here: The movie begins with Megamind falling out of the sky, then goes into a flashback as Megamind remembers his life. The time in between the beginning and ending points of the flashback must've been only a few seconds to Megamind.
Imposter Forgot One Detail: Titan realizes that Metro Man is actually a disguised Megamind when he pronounces "Metro City" as "Metrocity".
Incoming Ham: Megamind's arrival for the final showdown happens at the top of a large skyscraper, amid a laser-light show with smoke effects, with thousands of flying robot minions forming the illusion of Megamind's head, accompanied by the opening strains of Guns N' Roses' "Welcome to the Jungle".
Megamind: You dare challenge Megamind?
Titan: This town isn't big enough for two supervillains!
Megamind: Oh, you're a villain alright. Just not a super one.
Titan: Yeah? What's the difference?
[The giant head's mouth opens, and the actual Megamind walks out on the tongue.]
Indy Ploy: Megamind often resorts to these, as exemplified by the following quote:
Roxanne: What's the plan?
Megamind: Well, it mostly involves NOT DYING!
Roxanne: I like that plan!
There's also the fact that the brilliant stunt he pulls off at the end, snatching victory from the jaws of defeat, is only possible because he happened to be falling directly towards a fountain.
It Is Pronounced Tro-PAY/Malaproper: Megamind pronounces a lot of words oddly. Sometimes it is intentional in order to sound more evilish, other times it is just mispronunciation. For example, he says "Ollo" instead of "Hello", "Shul" instead of "School" (See also Bilingual Bonus above) and "Metrocity" (rhymes with "atrocity") instead of "Metro City". It becomes Something Only They Would Say later in the film.
After being kidnapped and held in Megamind's "deathtrap", Roxanne notices the spider (and pronounces it properly, of course). When Megamind tries to pretend it's part of the deathtrap, he pronounces it "spee-ider", which seems to be an attempt to make it sound more evil and exotic. However, the "Button of Doom" short has him referring to the "Spee-ider-bot", so apparently that's just how he says it.
Megamind isn't oblivious to this. When disguised as Bernard, Megamind begins to say "shool", but quickly says "school" properly.
It's All About Me: Even when everyone thought that Metro Man was dead, Hal Stewart seems to think it is an appropriate time to invite Roxanne Ritchi to his party. His selfishness is made worse by gaining superpowers.
Jerk with a Heart of Gold: Metro Man did seem at the beginning to be something of a jerk - starting off as a kid, growing up he became a hero and everybody loved him. It's easy to think that he's going to turn out to be the villain, not the loser Hal.
Just Eat Him: Sorta. Megamind's giant head made of thousands of brain bots does chew and chomp Titan, but it seems to be for show.
Karma Houdini: Although Titan ends up in jail, Megamind, who terrorized the city, "killed" Metro Man, created Titan, caused him to go crazy by abusing his evil technology, and committed enough previous evil acts to earn 88 life sentences, is revered as a town hero when all the good things he did was to stop his own creation. Of course, he makes up for it after the events of the movie.
Kryptonite Factor: Metro Man is vulnerable to copper. Or so he claimed. Turns out he was lying, and his real weakness, if any, remains a mystery.
Large Ham: Megamind, though Metro Man is not far behind him in the pork rating, and they both provide great Ham-to-Ham Combat. Averted with Titan. He is not much for posturing.
Also Minion, in his fake death scene.
Laser-Guided Amnesia: The Forget-me Stick. Megamind also mentions an "Illiteracy Beam" when he visits Metro Man's monument.
In The Button Of Doom short sequel, Minion mentions an "amnesia bomb" among Megamind's old schemes. Megamind doesn't remember that one.
Laser-Guided Tykebomb: Titan. Megamind wanted a superhero to fight. Unfortunately, the bullet hit the wrong candidate.
Last of His Kind: Apparently, both Megamind and Metro Man. Assuming Minion is/was actually part of a species and not just created in a lab, he might be this as well.
Lean and Mean: Subverted. Megamind is a skinny little guy, but honestly he is more mischievous than genuinely evil, and even that is not a solid condition for him.
Leitmotif: The riff from George Thorogood's "Bad to the Bone" is frequently used to represent Megamind, presented in different styles depending on the situation.
Let's Get Dangerous: Megamind isn't quite as incompetent as initially believed, it's just that he has a problem with not beta-testing his evil plans to iron out the kinks and he is generally outmatched by Metro Man. But normally, whomever utters the quote "You dare challenge me?" won't actually accomplish much, rather using it as a statement of overconfidence to brag about how supposedly unstoppable they are. But when you hear the phrase "You dare challenge Megamind?!", shit just got real!
Licensed Games: Not only was it cross platform, it was also touted as a sequel to the movie. Also, apparently Dreamworks has decided to use the supervillain group idea mentioned in the What Could Have Been entry below, in the games.
Longer-Than-Life Sentence: Megamind was sentenced to 88 consecutive life sentences for his crimes against humanity and Metro City. Largely meaningless, since he's able to waltz out the front door of his Cardboard Prison, and back into his functional laboratory lair.
Looks Like Jesus: Metro Man dresses in white, performs good deeds wherever he goes, walks on water and has people kissing his feet as he passes. Subverted in that he's only doing it because he thinks he has to.
