The Men in Black
Agent K/Kay (Kevin Brown)
- Adaptational Heroism: The comic book version of K was a Well-Intentioned Extremist at the best of times. Here, he's a Knight In Sour Armor who never crosses the line.
- Berserk Button: Don't mention to him that his wife left him because he pushed her away.
- Can't Stay Normal: He leaves the MIB at the end of the first film to live with his former girlfriend, but by the second film, she left him because Amnesia Missed a Spot.
- Chick Magnet: Evidently was this in his younger days, as all three movies involve a backstory regarding a different old flame.
- The Comically Serious: The movie's straight man, save for a quick scene in the first movie where he's telling J a joke and laughing a little too hysterically about it, and while singing along to Elvis Presley in the tunnel.
- Cool Old Guy: Just seems to kick more ass with age.
- Deadpan Snarker: Rarely communicates in anything but snark.
- Did Not Get the Girl: His return to his wife was short lived, as his feeling of something missing drove her away.
- He also had to let Lauranna go back to Zartha, and couldn't be with O due to M.I.B. agent dating policies.
- Drives Like Crazy: You best buckle up when he pushes that red button...
- Face Death with Dignity: When Boris goes back to erase him from existence, he fades away with utter calmness.
- Flanderization: In the first film, he's a rather stoic individual who takes his job seriously, but approaches everything with a calm demeanor, contrasting J who doesn't take the job seriously, but overreacts to everything. By the third, he's so stoic, he is unable to crack a joke or a smile.
- Jerk with a Heart of Gold: A crotchety, snarky old man. But it's shown several times that he's got a good heart.
- Luke, I Might Be Your Father: It's heavily implied he is Laura/The Light of Zartha's birth-father.
- Living Legend: In the second film, Kay is treated this way among young generation agents after his retirement. When a neuralized Kay arrives to the HQ, the agents fanboy over him.
- Living Lie Detector: His past self has a variation-he can tell when someone is telling the truth, no matter how unbelievable. Of course, given how he's a Man in Black.
- Mentor Occupational Hazard: Averted. He survives the Bug's innards to retrieve his gun and blast his way out.
- My Greatest Failure: In his own words, not killing Boris the Animal was the worst mistake he ever made. Easy to see why...
- The Mentor: Even years after J joins, he's still teaching him.
- My Card: How he introduces J to the world of the MiB.
- Oh, Crap!: Only once does he briefly lose his composure, thanks to witnessing the Bug revealing itself.
- Pop-Cultured Badass: He loves listening to Elvis Presley while he drives.
- Retired Badass: By the end of the first film and in the first half of the second film.
- Salt and Pepper: With J. Lampshaded several times.
- Seen It All: You'd be hard pressed to see any earth threatening menace faze him.
- Stalking Is Love: K uses the MIB's super-advanced Spy Satellites to spy on his old girlfriend while she's out gardening.
- The Stoic: He virtually never shows any true emotion. Despite this, it's hard to argue his life hasn't been tough.
- Worth It: His job required the severing of all social human contact, and dedicating his life day and night to fighting and policing aliens in secret. He still says, when asked by J before he joins up himself, it was "worth it... if you're strong enough."
Agent J/Jay (James Darrell Edwards III)
- The Ace: In K's absence, he becomes Earth's number one protector.
- Beware the Silly Ones: Yes, he comes off as pretty goofy (especially in the first movie) and at times doesn't seem to take things seriously. But he's definitely not somebody you want to underestimate.
- Bunny-Ears Lawyer: J is a goofy smartass but even in the first film is shown to be very competent when push comes to shove.
- Conveniently an Orphan: Which leads to his destiny in the agency.
- Cowboy Cop: To such a degree that Zed originally opposed his induction; "He has a problem with authority".
- Deadpan Snarker: More of a witty snarker than K.
- Deceased Parents Are the Best: His dad was apparently quite a guy. Which is proven true when we meet him in the past.
- Did Not Get the Girl: He grows close with Laura, but her being the princess of Zartha meant she had to return home.
- The Dreaded: By the time of the second film, junior MIB agents are terrified of J neuralyzing them for minor offenses.
- Genius Bruiser: He can beat aliens in a foot race and punch some of them out. But he's also a lateral thinker able to see the forest when everybody else is focused on the trees, susses out the initiative tests given to him during his MiB induction, is able to identify an alien weapon he'd previously encountered only once (during a scuffle, no less) and an (admittedly distinctive) alien he saw briefly while in the middle of MiB headquarters, and is usually able to make logical leaps that K can't.
- Hero of Another Story: Said to have saved the Earth several times during the time between I and II.
- Implacable Man: One of the reasons he got the attention of K. He ran down an alien called a "cephalapoid" on foot, which is implied through dialog to be quite a feat for a human.
- Naïve Newcomer: And he never totally grows out of it.
- Obfuscating Stupidity: The entire first act of the movie is designed to show that his streetwise smart-ass routine is largely a put-on and he's actually a very good, and even insightful, detective.
- Older Than They Look: Is treated as a fresh-out-of-college pup by K and the others despite his experience in NYPD. In the third movie he's revealed to be pushing 50, which would have made him mid-30s in the first film.
- Plucky Comic Relief: In the first film.
- Pre-Mortem One-Liner: To Serleena: "Your flight's been canceled!" Of course, she got better...temporarily.
- Race Lift: He was white in the comics.
- Ripple Effect-Proof Memory: Due to having been talking to K when he was Ret Goned (as well as, possibly, the fact that his younger self was present when history was changed), he apparently caused a temporal fracture that prevented his life story or memories from changing any as time reordered itself. Apparently, it induces a craving for chocolate milk.
- Salt and Pepper: With K. Lampshaded several times.
- Soul Brotha: Turned into this type of character in the second and third film.
- Uncle Tomfoolery: To a small degree in the first film, he was very comical and seemed to annoy agent K a little and he did not appear to take too many situations seriously.
- Unresolved Sexual Tension: In the first film and the animated series with Laurel Weaver, and the second film with Laura Vasquez. In the animated series, during J's perfect world alternate reality, he and Laurel are a couple. Or at least, her alternate reality self is J's girlfriend.
- Badass in Charge: He's mostly chained to a desk, being an administrator and all, but he's got some fire in him.
- Badass Beard: A sharp goatee.
- Big Good: The Leader of the MiB, Earth's "first, last and only line of defense".
- Bunny-Ears Lawyer: An odd, slightly kooky guy. But he runs the agency that keeps Earth safe from alien menaces.
- Cool Old Guy: Older than K, but still a semi-capable ass-kicker.
- Da Chief: To the organisation.
- Deadpan Snarker: Always ready for any situation with a retort.
- Dirty Old Man: He's got some stories of his past sexual exploits that make J shudder.
- It Is Pronounced "Tro-PAY": "Zed" is how the letter Z is pronounced in European countries (deriving from Greek "Zeta"), while Americans typically pronounce it as "Zee".
- Sudden Sequel Death Syndrome: Rip Torn's DUI conviction caused the creators to write him out of III.
- Big Good: She is Zed's substitute after the latter's death.
- Large Ham: O has one moment of "screeching" the scenery of the MiB HQ, when she dedicates some words to Zed in an alien language.
- Remember the New Guy?: She never appeared in the first two films but apparently had been working at MIB for at least as long as K had.
Agent H (Henry)
- The Ace: Is one of the MIB's best agents.
- Actor Allusion: During a confrontation with an alien, Chris Hemsworth's Agent H wields a hammer, which he throws at an alien, who catches it. The lyrics of the music are even timed for an "oh snap" in reference to Avengers: Infinity War.
- Amnesiac Hero: Doesn't realize that he was neuralised at the Eiffel Tower at the beginning of the movie.
- Bunny-Ears Lawyer: He's an incredibly laid-back playboy, but he's also a highly effective Man in Black.
- Like a Son to Me: High T says it about him, and he reciprocates the feeling.
Agent M (Molly Wright)
- Big Bad: Of International. He turns out to be the mole in the Men in Black and the one paving the way for a Hive invasion.
- Mole in Charge: Was killed and replaced by a member of the Hive.
- One-Winged Angel: His Hive form at the end.
- Inspector Javert: Spends most of International acting under the impression that H and/or M are moles.
- Jerk with a Heart of Gold: He's rather antagonistic, but ultimately a loyal protector of the planet.
- Red Herring: His obvious antagonism of H and M make him a prime candidate for being The Mole. It's not him; it's High T.
Dr. Laurel Weaver (Agent L/Elle)
- Adaptational Dye Job: She's blonde in the cartoon, yet the same hairstyle.
- Badass Normal: I mean, not everybody is able to quickly handle a high-tech gun and use it to blow up a giant Creepy Cockroach to bits with so much ease.
- Big Damn Heroes: Saves J and K from almost getting eaten by the Bug by shooting him from behind.
- Damsel in Distress: Edgar promptly takes her hostage once he discovers she has the galaxy, and attempts to take her with him so he can eat her.
- Damsel out of Distress: When Edgar tells her he wants to take her with him to eat her and feed his family as well, while climbing to his UFO, Laurel has none of it and breaks free of his hold, then jumps into a nearby tree while fiercely clinging to one of its branches to avoid falling. She eventually falls, but is unharmed and manages to get a hold of J's gun which she uses to shoot the Bug and kill him for good.
- Dangerously Short Skirt: As part of her work attire.
- Deadpan Snarker: The girl certainly has her moments.
- Disposable Love Interest: Was introduced as a potential love interest for J and even becomes his new partner after K's departure, but vanishes in the sequel with J handwaving it as her wanting to go back to the morgue. In the Animated Adaptation which is set in an Alternate Continuity after the first movie, she and J have Unresolved Sexual Tension most of the time.
- Hot Scientist: She specializes in mortuary science and is very good-looking.
- Jerk with a Heart of Gold: Laurel may be cynical, snarky and gets annoyed easily, but truly cares for those she likes. At one point near the end, while Kay and Jay have an emotional moment regarding the former's departure, she chimes in, saying her apartment isn't very near, not even on the same island, but does it in a pleasant manner and doesn't seem annoyed at all.
- Ms. Fanservice: She is played by the gorgeous Linda Fiorentino and almost always wears a rather short skirt which shows a good deal of her legs.
- Off Screen Break Up: Between her and J.
- Put on a Bus: Her absence is explained by J claiming she wanted to go back to the morgue to continue working there and thus he neuralyzed her.
- Quiet Cry for Help: When J and K come to the morgue looking for Orion, J finds Laurel and asks her where the cat is, all while Laurel tries to quietly tell him Edgar is holding her hostage and has threatened her with death if she gives him away. Jay persistently misinterprets her attempts to alert him as sexual come-ons.
- Sequel Non-Entity: See Put on a Bus above. The truth is, Linda Fiorentino turned out to be an insanely difficult actress to work with, thus the character of Laurel was written off.
- She's Got Legs: She is played by none other than Linda Fiorentino, after all.
- Skewed Priorities: Once Edgar gets Orion's belt in his hands and takes her captive, she's more upset about J misinterpreting her attempts to warn him of Edgar's presence as sexual come-ons, than the fact she's being held at gunpoint by an intergalactic criminal who can end her life at a whim with no remorse whatsoever.
- The Coroner: Her main job at the morgue.
- Unresolved Sexual Tension: With Agent J.
Frank the Pug
- Amusing Alien: Frank is one of the funniest characters in the series.
- Ascended Extra: In both in the sequel and the animated series.
- The Dog Is an Alien: He's an alien disguised as a Pug dog.
- Jerkass: Frank is crass, rude, and unnecessarily snarky.
- Jerk with a Heart of Gold: Frank can be surprisingly insightful, and his heart is in the right place.
- Talking Animal: While he's actually an alien, he certainly invokes this trope.
- Alien Blood: When his head is shot off, green goo is smeared all over the walls.
- Arms Dealer: He sells illegal alien weapons from his black market pawn shop.
- Why Am I Ticking?: Her bracelet turns out to be a nuclear grade weapon that goes off if the light doesn't get off Earth.
- Adorkable: The goofy hat and chipper personality just make him adorable.
- Bait-and-Switch: He manages to trick Boris into thinking that the Ark-Net is inside the large box-shaped necklace he's wearing, but it's in fact inside a box of snacks he's later seen eating at a baseball stadium, and the final component he hid inside his head.
- Blessed with Suck: He has no ability to tell possible futures that won't happen from the ones that will, which is harrowing in situations where he has no idea whether he's about to die or not, and usually sees them months before they happen or are even relevant in the first place. He considers the constant visions "a gigantic pain in the ass."
- Catchphrase: "That was a close one!" Said every time one of the horrible outcomes to the current situation he is in does not come to pass.
- Cloudcuckoolander: A symptom of being The Omniscient. He literally sees things that aren't there and for the most part never will- so he comes off as outright kooky a lot of the time. Though... given his maniacally childish glee at the prospect of using a jetpack, that might not entirely be due to future shock.
- Description Porn: When he's found at a baseball stadium witnessing a game months in advance, he gives a ridiculous analysis of one reality he's trying to watch, down to the detail of how an event occurred such as one player existing because he got a baseball as a Christmas present at childhood since his father couldn't find a football.
- Fling a Light into the Future: His kind were killed by the Boglodites when they came for sustenance, thus leading him to try and get the Ark-Net deployed to save Earth and many others as well due to the Boglodites needing to constantly eat, meaning if they aren't able to devour the contents of the planet they've found, they'll die before reaching the next one.
- Humanoid Abomination: A cute and cuddly one, but still a fifth-dimensional being with a perspective utterly alien to humans that takes human form.
- Manic Pixie Dream Guy: Kinda.
- Motor Mouth: Due to constantly seeing potential futures, he has a habit of blathering on, trying to get even a fraction of the knowledge he has out, this amounts to endless unbroken sentences.
- The Omniscient: Able to see every outcome, in every reality. Simultaneously.
Colonel James Darrel Edwards II
- Colonel Badass: His badassitude helps save the world from Boris.
- Mental Fusion: Griffin does this to him to get his help on defeating Boris, which works. It's never stated what he saw, but whatever he saw must have had a connection to J, who is a grownup version of his son.
- No Name Given: Only referred to as "Colonel" or "Sir". Mostly so his relation to J wasn't obvious to the audience.
- Big Damn Heroes: As M is knocked into the portal in the Eiffel Tower straight towards the Hive, Pawny flies in after her and uses one of his grappling guns to catch her. He then uses his other gun to pull them both out of the portal and back into the Eiffel Tower.
- Deadpan Snarker: Mostly towards H.
- Jerkass to One: Pawny really, really hates H.
- Lilliputians: He and his race are so tiny that their armor resembles chess pieces.
Vungus the Ugly
Edgar the Bug
A deadly terrorist of the Bug species, he comes to Earth with the intent of finding Orion's belt so he can kickstart an Arquillian war against Earth, which would result in the deaths of many, allowing him and his brethren to feed on all the dead bodies they want.
- Adaptational Villainy: The original human Edgar is loosely based on a farmer who appears in #2 of the comic book. However, unlike his wife-beating movie counterpart, the farmer is decent enough, if a bit trigger happy. He also isn't killed, as the aliens who appear in the issue aren't hostile, their appearance is due to a misunderstanding.
- Aliens Speaking English: Subverted. He briefly speaks in English when he's about to kill the farmer, as well as when he's in his disguised state, but it's mostly the result of a low-quality translator. Apparently, his native tongue consists of aggressive, loud growls and roars. Oddly enough, his fellow bugs are totally fluent in English in the cartoon, even in their true forms.
- Asshole Victim: The bug was not a nice creature to begin with but the real Edgar was an abusive husband who only cared about himself. Few tears were shed, in-universe or out, when the bug killed him and wore his skin. In fact one of the big hints to Edgar's wife that something is wrong is that the bug is too nice compared to the real Edgar when pretending to be him.
- Ax-Crazy: He tends to attack and/or kill everyone he runs into.
- Berserk Button: Hurting insects, particularly roaches.
- Big Bad: Of the first film. He kills the Arquillian Prince Rosenberg while searching for the galaxy of Orion, which the Arquillians give the MIB one hour to retrieve before they destroy the Earth.
- Body Horror: He's a giant insect shambling around in the decaying skin of a farmer. So... yeah.
- Deadpan Snarker: For a giant, dumb bug, he has the occasional barb.Edgar: You don't matter. In fact in a few seconds, you won't even be matter.
- The Dreaded: The very threat of him showing up makes what was apparently a failed minion commit suicide, and causes lots of aliens to try to jump ship and leave Earth. Implied to be because he brings the "bug war" to Earth.
- Even Evil Has Loved Ones: He cares more about his race and Earth's insects than any other lifeform in the universe. Killing them is a Berserk Button. And, as the cartoon shows, the feeling was mutual, as Edgar's brother, Edwin, is sent to Earth by the Bug Queen to capture Agent L, who was responsible for Edgar's death, with the intent of bringing her to the Bug homeworld in order to torture and kill her so they can avenge Edgar's demise.
- Evil Is Bigger: Edgar the bug is a giant imposing cockroach-like alien. Though not like the human Edgar was small to begin with, as he was played by the 6' 3'' ft. Vincent D'Onofrio.
- Evil Sounds Deep: More so out of disguise.
- Extreme Omnivore: The very first thing he does upon revealing his true form is quickly disarm J and K by devouring their guns.
- Fantastic Racism: Towards humans and mammals as a whole.
- Foil: To the human Edgar. The human Edgar is a selfish farmer and an abusive husband. The bug cares about his family and every living arthropod.
- Genuine Human Hide: He's disguised as a farmer he killed and is wearing his skin. The wife of said farmer describes him as looking like he's wearing an 'Edgar suit'.
- Genius Bruiser: Gigantic, super strong and merciless. He's also pretty good with technology and quite cunning.
- Hair-Trigger Temper: It doesn't take much to piss him off.
- Half the Man He Used to Be: Blown apart at the waist when K fires a BFG from inside his stomach. Amazingly, this didn't kill him; it took a second shot from another BFG to do that.
- Hot-Blooded: Very much so, even when you don't trigger his temper, he's certainly got a level of hostility.
- Hugh Mann: His attempts to pass for human are unrealistic at best.
- Insectoid Aliens: A big one.
- Karmic Death: He's ultimately destroyed by the very same chick he kidnapped and held hostage with the intent of devouring her.
- Kick the Son of a Bitch: The farmer whose body he uses to 'blend in' is not exactly the nicest of people.
- Kill and Replace: Kills Edgar and then puts on his skin.
- Large Ham: Subtlety doesn't appear to be a species trait.
- Lightning Bruiser: He's a monstrous insect with Super Strength and can escape crashed spaceships unscathed. He's also pretty quick for something of his size; he can snatch your gun from your hand before you have a chance to pull the trigger.
- More Teeth than the Osmond Family: As a bug.
- No Name Given: He's called Edgar by everyone because he takes over the body of someone named Edgar. His real name- if he has a real name- is never mentioned.
- One-Winged Angel: When he sheds his Edgar suit for a final confrontation with J and K.
- Politically Incorrect Villain: The bug himself considers humanity and other alien races inferior. On the other side, Edgar the farmer insulted his wife very frequently and told her to "get [her] big butt back in the house" when the bug's spaceship landed.
- The Quiet One: For some reason he stops talking once he gets rid of his human disguise and starts roaring and growling instead.
- Scary Teeth: He has very long sharp teeth in his true bug form.
- Sesquipedalian Loquaciousness: His first words to the farmer, due to a poor-quality translator; "put your projectile weapon on the ground" and "your proposal is acceptable".
- Super Strength: He's a T-Rex-sized space roach crammed inside a person-suit and his strength level reflects that, especially after he goes One-Winged Angel by discarding said person-suit.
The Queen of the Kylothians, she seeks out the Light of Zartha to use it so she can destroy Earth and Zartha and have her species rule the galaxy unopposed.
- Arson, Murder, and Jaywalking: Serleena murders Ben after he refuses to divulge the location of the Light of Zartha. She also steals some of the pizza from his restaurant.
- Authority Equals Asskicking: She is the Queen of the Kylothians yet she personally comes to Earth to find the Light of Zartha and use it to take over the galaxy, and she is quite happy to kick the ass of anyone who gets in her way.
- Balloon Belly: Serleena gets one after swallowing the mugger in the park whole, which she manages to get rid of by spitting his boots back up.
- Big Bad: Second movie.
- Big Eater: Her entire species are implied to be this.
- Black Bra and Panties: When she lands on earth and takes human form, this is all she is wearing along with a pair of high heel shoes, which gets the attention of a mugger.
- Cute Monster Girl: "Smoking hot" is more appropriate.
- Combat Tentacles: A whole lot of them too.
- Deadly Upgrade: After she infected Jeff.
- Deadpan Snarker: Particularly when dealing with Charlie and Scrad.
- Dark Action Girl: She's no weakling, and easily overpowered trained agents in a fight. Is also a sadistic, greedy murderous alien.
- Eerie Pale-Skinned Brunette: Takes the form of one upon arriving on earth.
- Eldritch Abomination: Her true form.
- The Worm That Walks: A walking mass of writhing tentacles.
- Evil Is Petty: She spends the opening credits destroying planet after planet solely because the Light wasn't there.
- Evil Is Sexy: Invoked in-universe. She actively invokes this when she takes the form of a lingerie model. At MIB customs, her alias is an alien that wants to be an underwear model.
- Fan Disservice: After eating a mugger, her belly gets really grotesquely bloated and flabby, all while still wearing sexy lingerie.
- Hell-Bent for Leather: Trots around in a stolen biker outfit for most of the movie.
- Humanoid Abomination: Spends most of the film in the form of an attractive model, manifesting Combat Tentacles from her fingers if she has to fight or coerce someone.
- If that wasn't bad enough, she can also eat humans whole, which gives her human form a large, bubbling belly.
- Lecherous Licking: She sticks her tongue in Agent K's ear. Earlier on, she receives one herself from a mugger before she eats him.
- Ms. Fanservice: This is an early 2000's Lara Flynn Boyle we're discussing...
- Mugging the Monster: When she assumes human form in Central Park, she is only wearing a Black Bra and Panties and high heeled shoes. Naturally this attracts the attention of a mugger who drags her behind a bush at knife point. Serleena then immediately turns the tables on him and swallows him whole while all he can do is scream in terror.
- Oh, Crap!: When she meets head on with Jeff.Serleena: Oops. Teeth.
- The mugger also has a moment of this right before Serleena eats him.
- One-Winged Angel: When she eats Jeff, she becomes a gigantic-sized version of her true form.
- Person of Mass Destruction: She takes out the entire Men In Black NY division pretty much single-handedly. She muses that she could probably take over the entire planet without too much trouble as well if she were so inclined. She is probably the most powerful villain in the movies and one of the strongest in the entire franchise.
- Pre-Mortem One-Liner: Gives one to the mugger after he tried to rape her.Mugger: Hey pretty lady, *licks her face* you taste good... ...hey, what the—?! [mugger screams accompanied by the sounds of Serleena swallowing him head-first]
Serleena: Yeah, you too.
- Sexy Coat Flashing: As a distraction at MiB headquarters when she is dealing with customs.
- Starfish Aliens: In her true form, Kylothians like her are worm-like beings made of several tentacles which can assume distinct forms and achieve gigantic sizes.
- Swallowed Whole: She went both ways with this.
- To Serve Man: Seems to really enjoy eating her opponents, as a man in the park at the start (albeit a would-be mugger and rapist) and Jeff the Worm learned the hard way.
Charlie & Scrad
- The Dragon: Before Jarra shows up.
- Minion with an F in Evil: A couple of chuckle-heads who suck at their job.
- Punch-Clock Villain: Just dicking around on Earth before their boss showed up.
- Reluctant Monster: Begins the story trying to live a normal life, until Serleena turns up.
- What Happened to the Mouse?: They vanish after the rumble in Jeeve's basement.
- Conspicuous Trenchcoat: What he hides his mini-body and clones under.
- The Dragon: To Serleena, after Charlie and Scrad disappear.
- Evil Is Bigger: Subverted. He appears to be like this. But when the coat came off it's revealed that he is very tiny and his lower half is a small flying saucer with multiple controls for flying.
- Evil Genius: Serleena flatters him by saying it was criminal that someone as intelligent as him was ever arrested; she is probably at least half-serious, since there was no reason she couldn't simply have forced him to work with her like she does everyone else.
- Gadgeteer Genius: Constructs a space ship for Serleena to use in a matter of hours, and presumably built a device with which to carry out his plan to steal the ozone layer.
- It's Personal: His price for working with Serleena is simply revenge on J, the agent who arrested him.
- Me's a Crowd: He's actually four tiny identical humanoids on tiny flying saucers
- Planet Looters: He tried to steal the Earth's ozone to sell on the black market.
- Villainous Friendship: Seems to have a pre-existing one with Serleena. At the very least they know and respect one another and are happy to work together.
Boris the Animal
The last of the Boglodites, he is a deadly alien bent on letting his race devour everything they come across, and planet Earth certainly is on the menu.
- Aliens Speaking English: He's a malevolent alien, but is seen in a Monstrous Humanoid form throughout the film and speaks in English.
- An Arm and a Leg: Had his arm blown off by K. It's a... touchy subject.
- Arch-Enemy: To K.
- Ax-Crazy: Exists solely to kill and wreak havoc.
- Badass Biker: His preferred image in 1969.
- Badass Beard: How his species grows hair is a mystery...
- Batman Can Breathe in Space: Is unaffected by the vacuum he starts in the Lunarmax prison. And he actually talks to himself in the airless void of space afterwards.
- Beard of Evil: A big, bushy one.
- The Berserker: Oh, big time.
- Berserk Button: Do not, under any circumstances, call him "The Animal". J uses this Berserk Button to defeat him.
STOP! STARING AT IT!!
- He doesn't like when people stare at his lost arm, either.
- Big Bad Duumvirate: Uniquely, present-Boris and 1969-Boris team up to fight the time traveling MIBs.
- Blood Knight: Boris loves to fight and kill.Hippie Girl: Make love, not war.Boris: I prefer to do both.
- Contrasting Sequel Antagonist: Is downright terrifying, even when compared to Serleena. While Serleena mainly used subterfuge to try and get to her endgoal, Boris uses straight-up brute force to get what he wants; Serleena copied an attractive model's ideal image, while Boris stuck with an appropriately brutish and unkempt appearance with a few spots of his true form showing through (the spots where his skin zig-zags, such as his wrist and the sides of his eyes). Both are deep arch-enemies of K, but Boris is the one that K considers My Greatest Failure in not killing him.
- Evil Sounds Deep: Both in the past and present, but his voice is slightly deeper in the past.
- Expy: Jemaine Clement does one hell of a Tim Curry impersonation.
- Eyeless Face: In his true form.
- Famous Last Words: For his future self: "THAT'S. NOT. POSSIBLE!!" (this is when J uses his time tricks to throw him into the exhaust of the rocket). For his past self: "GO AHEAD! ARREST ME!!" K replies, "Not this time", and blasts him.
- Faux Affably Evil: He barely bothers with the facade most of the time.
- For the Evulz: He surely enjoys mass killings.
- Genius Bruiser: For all his bloodlust and viciousness, he's a sharp cookie.
- Goggles Do Nothing: Well, except for disguise purposes since he has no eyes at all
- Guttural Growler: On par with Nathan Explosion.
- Hair-Trigger Temper: That trigger is very itchy.
- Ham-to-Ham Combat: With himself, when he meets his past self.
- Handicapped Badass: In the present, where he only has one arm.
- Hero Killer: Killed J's father, killed K in an alternate reality.
- I Hate Past Me: He doesn't even like himself in the past, seeing his past self as responsible for his failures. The feeling, obviously, is mutual for the '69 Boris who considers his older version the cause of his future fail.Boris (present-day): You pathetic waste of Boglodite flesh. I'd kill you right now if I didn't value my own life. [...] Look at you. Every mistake I ever made just waiting to happen.
- Improbable Aiming Skills: He's a pretty good shot with his spikes, managing to wipe out a squad of security guards before they manage to get off a shot, and generally managing to hit whatever he's aiming at as long as there's no obstacles in the way. When J manages to dodge his spike shots during the final confrontation thanks to a little time travel prescience, Boris is completely flabbergasted.
- Karma Houdini: In the alternative present.
- Kill It with Fire: This is how Future Boris dies. J throws him into the exhaust of the rocket.
- Knight of Cerebus: Edgar and Serleena were pretty nasty. However Boris is FAR WORSE since he murders Agent J's father, as well as Agent K in the modified '69.
- Serleena and Boris are more or less equal in evilness, since both engage in on-and off-screen multiple planetary genocide.
- Large Ham: There's barely any scenery left when he engages in a conversation with his past self, courtesy of his actor, Jemaine Clement (who is no stranger to Large Ham performances).
- Last of His Kind: The Boglodite species died out thanks to the Ark-Net protecting Earth. Except for Boris.
- Laughably Evil: Boris is incredibly sadistic and evil, but his deadpan humor and hammy chat with his past self will most certainly inspire a few chuckles from the audience.
- Lightning Bruiser: Surprisingly agile during combat and hits really hard.
- Made of Iron/Super Strength: Though his physical capabilities are much closer to humans than previous Big Bads, he's still quite a bit stronger and tougher than humans, being able to survive things like having his bike blown up or being dropped a few hundred feet, as well as proving to be somewhat stronger than J in a fistfight even with only one arm.
- Mirthless Laughter: An absolutely epic one.
- More Teeth than the Osmond Family: His whole body is made of teeth.
- Names to Run Away from Really Fast: Even if he doesn't like the nickname, he's still known as Boris The Animal.
- Near-Villain Victory: In the modified present he actually succeeds in killing K and spreading the Boglodite invasion of Earth and probably consuming the entire planet. This is only prevented by J's interference in '69.
- Nightmare Face: Go ahead...arrest me.◊
- No Indoor Voice: His quietest tone seems to be a dull roar.
- Obviously Evil: From the beard, to the voice and especially the personality, the guy is obviously bad news.
- One-Man Army: Just ask those poor MIB agents on the moon.
- Planet Looters: His entire species.
- Psycho for Hire: To the Boglodites.
- Red Baron: He might dislike the name, but he still is Boris The Animal.
- Roaring Rampage of Revenge: Towards K.
- Sealed Evil in a Can: They built a prison specially for him in the moon (though it seems there are other prisoners there), his escape kicks off the plot (literally: it is the opening scene of the movie).
- Serial Killer: Sort of; while he's happy to just kill at random, he undoubtedly premeditates several of his hits. He also regularly goes on killing sprees.
- Sinister Shades: Just adds to the menace.
- The Sociopath: The guy makes Edgar look like a member of UNICEF...
- Spike Shooter: His weapon of choice, courtesy of a spider-like symbiote that seems to live inside his right hand.
- Suicidal Overconfidence: His Fatal Flaw (at least in the past), his future self calls him out on it.
- This Cannot Be!: A variation of this is 21st century Boris's Famous Last Words. "THAT'S NOT POSSIBLE!"
- Ungrateful Bastard: He lets his girlfriend die, even after she sprung him out of prison...
- Villainous Breakdown: Future!Boris becomes increasingly (more) wrathful when he starts to lose the edge of the battle, culminating in the scene where he falls off the platform screaming "THAT'S NOT POSSIBLE!".
- Villain Opening Scene: He's the first major character to be seen in the film, and his escape starts the whole plot.
- Violence Is the Only Option: Firm believer of this.
- Weak, but Skilled: Though still stronger and tougher than regular humans, his physical capabilities are nonetheless much closer to the human norm compared to Edgar, Serleena, or the villains from the cartoon series. He still manages to be a very credible threat due to having a smart plan, solid operative skills, and pretty damn good aim.
- You Killed My Father: He killed Agent J's father in '69.
- You Have Outlived Your Usefulness: During the opening prison break, he goes out of his way to kill another prisoner that he apparently had an escape deal with, as well as tossing his erstwhile gun-moll out into space once he no longer needs her.
- Monster Fangirl: Provides the page image.
- You Have Outlived Your Usefulness: In Boris's defense, he made an effort to keep her alive. In her defense, he didn't try very hard.
- All There in the Manual: Their names are only listed in the credits.
- Asshole Victim: Even if they turn out to have the best intentions for their people in mind, it's undermined by their "shoot first, explain ourselves later" attitude and no one, in-universe or out, cries for them when they get obliterated by an MIB death squad.
- Combo Platter Powers: Their powers don't really have defined limits. They can absorb someone's appearance, teleport, telekinetically warp matter into new shapes, pass through walls, and manipulate earth. And because they're Energy Beings, they can just reform any holes that get blasted in them.
- Disc-One Final Boss: They arent part of the Hive, and they need the weapon to kill it. The real villain is High T.
- Dropped a Bridge on Him: After proving immune to everything the MiB throw at them, they are abruptly blasted apart by a squad of MiB agents in the middle of a confrontation with M and H. T nonchalantly Hand Waves it as having found the right voltage to kill them.
- Energy Being: In their natural forms, appearing as swirling clouds of cosmic energy with a humanoid form just barely visible inside. Their presence causes light bulbs to flicker and blow out. Despite this, they apparently still have DNA.
- Well-Intentioned Extremist: The Twins only want to save their planet from the Hive, but they are willing to do anything to accomplish this goal and murder several innocents in the process.
- Greater-Scope Villain: Of International, with High-T serving as their mole.
