The Men in Black

    Agent K 

Agent K/Kay (Kevin Brown)

Voiced by: Ed O'Ross (Season 1), Gregg Berger (Seasons 2-4)

One of the two main protagonists. Just like the film, Agent K is a veteran MIB agent who has served the organization since it was founded.

  • Adaptation Dye-Job: He's grey-haired in the film, but here in the cartoon he's a brunette.
  • Age Lift: Sort of. He's still approximately the same age as in the movie, but he looks a few decades younger for some reason - then again, given that it has been established he can control his metabolism well enough to survive almost two hours without breathing, it can be assumed that he can slow down aging as well.
  • Badass in a Nice Suit: Being one of The Men in Black after all.
  • Catchphrase: Whenever he and Jay introduce themselves to witnesses, he claims they come from "[Insert organization name], Division 6." In a later episode this is justified as the division of MIB he and Jay are part of is called "Division 6".
  • The Comically Serious: Much of his humor comes from his unsurprised reactions to everything about his job.
  • Cool Old Guy: A very skilled and experienced veteran agent with quite a reputation for being awesome.
  • Deadpan Snarker: With emphasis upon deadpan, mush to Jay's annoyance.
  • Jerk with a Heart of Gold: He often gives Jay a hard time, but really does care about his well-being.
  • Seen It All: Having served the MIB for decades, he's seen a lot of paranormal weirdness and is rarely ever shocked by anything new.
  • The Stoic: The animated Kay is even more stoic than the live-action Kay, which is really saying something. He rarely ever shows any emotion on his face.
  • Trickster Mentor: He has a rather odd way of teaching Jay how to do things, and sometimes even withholds information from him until later.

    Agent J 

Agent J/Jay (James Darrell Edwards III)

Voiced by: Keith Diamond

The other co-protagonist. Just like the film, he's Agent K's partner, and a naive rookie agent who's still learning how to do his job.

    Chief Zed 

Chief Zed

Voiced by: Charles Napier

The current leader of the Men in Black.

    Agent L 

Agent L/Elle (Dr. Laurel Weaver)

Voiced by: Jennifer Lien (Seasons 1-3), Jennifer Martin (Season 4)

An MIB doctor and scientist, and part-time field agent.

    Agent X 

Agent X

Voiced by: Adam Baldwin

An alien police officer who joins the MIB in Season 4 due to pressure by alien activist groups. He's assigned to be Agent L's partner.

  • Adaptation Species Change: There's an agent in the original comics named Ecks, who's human and a rogue agent.
  • Anti-Hero: His morals are considerably looser than the other agents.
  • Badass in a Nice Suit: Being one of The Men in Black after all.
  • Blood Knight: He seems to enjoy getting into action and combat for its own sake.
  • Cowboy Cop: Impulsive, reckless and insanely gung-ho. L describes him as being less like a "loose cannon" and more like a "megaton bomb". The only reason she's stuck with him is because Zed is giving her a chance to be a field agent, and X was sent by his people as an ambassador, so Zed killed two birds with one stone, but has to deal with their incisive bickering.
  • Deadpan Snarker: He makes a lot of unflattering remarks about Earth and humans.
  • Fantastic Racism / Politically Incorrect Hero: He openly regards humans as being inferior to his kind.
  • Fiery Redhead: Although his true form is completely bald, his Human Disguise includes red hair, which perfectly suits his hot-blooded personality.
  • Good Is Not Nice / Jerkass: Tact and politeness are not his strong suit.
  • Hero of Another Story: He was a notorious policeman back in his home galaxy, and was awarded for bravery (and suspended for recklessness) multiple times.
  • Sixth Ranger: He's introduced and joins the main cast only in the fourth (and final) season.

    The Twins 

The Twins (Idiukupkup and Bob)

Voiced by: Pat Pinney and Pat Fraley

Two aliens who help coordinate MIB missions.


    Dr. Zeeltor 

Doctor Zandozz Zeeltor

Voiced by: Steve Kehela

A genius alien scientist who starts working for the MIB in Season 4, replacing Elle as the leader of the science department.

    Agent U 

Agent U/You (Upton)

Voiced by: Unknown

A minor MIB agent who appears occasionally.


    The Worms 

The Worms

Voiced by: Pat Pinney and Pat Fraley as two Worms each

Four small yellow aliens who frequently hang around the kitchen in the MIB headquarters. They have an overwhelming addiction to coffee.

  • Amusing Aliens: They're the single greatest source of comic relief in many episodes.
  • Ascended Extras: They only appeared in one scene in the first movie, but they're frequently recurring characters in the cartoon.
  • Manchildren: All of them behave like immature children who can't ever have enough candy (or coffee in their case), and are prone to doing stupid things without ever thinking of the consequences. They even go trick-or-treating in the Halloween Episode, with Agent J supervising them like a reluctant babysitter.
  • Must Have Caffeine / Trademark Favorite Food: They are extremely obsessed with drinking coffee, always talking about it and planning to obtain more of it. They say that only royalty is allowed to drink it on their planet, so it's quite a Forbidden Fruit for them.
  • The Pirates Who Don't Do Anything: It's implied that they're employees of the MIB, but all they do most of the time is just drink coffee in the kitchen. Apparently they lied to their Emperor about serving the MIB as elite agents.
  • Sidekick Creature Nuisance: All of them are quite diminutive, and tend to get on the nerves of other people at MIB (especially Chief Zed, as the Worms like to steal coffee from his office).
  • Skewed Priorities: Their efforts to get coffee by any means (including leaving MIB HQ without a disguise) often leads to chaos and trouble.
  • Too Dumb to Live: To give one example, when the Worms were assigned to help with maintenance on the MIB's nuclear reactor, they tried using hot water from the cooling system to make coffee. The result was as disastrous as you would expect.

    Troy the Symbiote 

Troy the Symbiote

Voiced by: Rino Romano

A young alien creature who left his mother to join MIB as an intern. He needs to be attached to another organism to survive.

  • Amusing Alien: Due to being a hyperactive, talkative kid.
  • Chuck Cunningham Syndrome: He stops appearing after the first couple seasons.
  • Fanboy: He's very fond of Earth's pop culture, especially Hollywood movies.
  • Fusion Dance: If he were to be attached to a single host for more than 20 hours, they'll permanently become one. So he constantly jumps from one host to another.
  • Healing Factor: Symbiotes and their hosts can regenerate just about any injury. They can also heal others with a touch.
  • Motor Mouth: There's rarely a moment when he doesn't have anything to say, and he'll chatter on and on to his hosts.
  • The Pollyanna: Always cheerful and optimistic.
  • The Symbiote: His species can only survive by living in the bodies of other beings.
  • Voluntary Shapeshifting: To an extant. He can't disguise himself as anyone, but can change his host's limbs into weapons and such.


Agent Aileen

Voiced by: Beth Broderick

A female alien agent who serves an extraterrestrial organization affiliated with the MIB. And an old colleague of Kay whom he knew "intimately".

  • Action Girl: She's a female alien cop.
  • Badass in a Nice Suit: Not a member of Earth's Men in Black, but she serves a very similar law enforcement group from another planet.
  • Combat Tentacles: Her fingers are stretchy tendrils that can extend to long lengths, very useful for grabbing and climbing on things.
  • Green-Skinned Space Babe: She has blue skin, but otherwise her true body doesn't look much different from her Human Disguise.
  • It's Personal: At one point she assists Kay and Jay with recapturing a shapeshifting criminal that killed her previous partner.
  • Love Interest: She's an old lover of Kay whom he still has strong feelings for. Jay even notes how Kay acts much less stoic around her.

    Frank the Pug 

Frank the Pug

Voiced by: Eddie Barth

A dog-like alien disguised as a dog. He's frequently a paid informant for the MIB.

    Jack Jeebs 

Jack Jeebs

Voiced by: Tony Shalhoub (first few episodes), Billy West (rest of series)

An alien criminal who runs a black market pawn shop. He's a reluctant MIB informant who often gets his head blown off.

  • Alien Blood: He frequently bursts into a puddle of green goo whenever attacked.
  • Amusing Alien: Due to constantly receiving Amusing Injuries.
  • Arms Dealer: He often sells illegal weapons to various alien criminals passing by his shop.
  • Ascended Extra: He plays a greater role in the TV show than the film.
  • Blatant Lies: Whenever interrogated by Jay and Kay, Jeebs will claim not to have interacted with any criminals who visited his shop. He's never able to convince them.
  • Butt-Monkey: Jeebs will get comically abused and seriously injured Once per Episode, most often with his head being blown up.
  • Cain and Abel: The Abel to Dak's Cain. Downplayed because Jack himself is an amoral slimebag, though nowhere near as bad as his brother.
  • Catchphrase: "That really stings!"
  • Dirty Coward: He'll do anything to save his own skin whenever threatened by others. For example, attacking other aliens when Alpha forcefully demanded that he give him some new body parts.
  • Friend in the Black Market: A merchant of illicit goods who's deeply connected to the alien underworld.
  • Healing Factor: He instantly regenerates from any injury he suffers, no matter how extreme. This unfortunately drives many characters to shoot his head off constantly as a threat, which according to Jeebs still hurts.
  • Heel–Face Revolving Door: As his only true allegiance is to himself, he'll help both the MIB and their enemies, depending on which immediately benefits him more.
  • Honest John's Dealership: His store even looks like a typical shady pawn shop.
  • Human Aliens: He's not wearing a disguise as far as we can tell.
  • Jerkass: He only looks out for his own self-interest.
  • Losing Your Head: Happens so often that it's a Running Gag.
  • Only in It for the Money: Greed is his main motivation.
  • The Stool Pigeon: Much like Frank, he often informs the MIB about criminal activity (albeit very reluctantly).

    Emperor Worm 

Emperor Worm

Voiced by: Danny Mann

The monarch of planet Takwalla, which is the homeworld of the Worms. He comes to visit Earth for diplomatic matters twice.

  • Adipose Rex: He's both taller and fatter than the other Worms, and he even likes to call himself as being "Large and in Charge".
  • Aliens Speaking English: Subverted. He tries to speak English, but his grasp of the language is incredibly poor (at one point, the four Worms even ask him to restate what he said in their native language). See My Hovercraft Is Full of Eels below.
  • Berserk Button: He doesn't take it well when he catches the quartet of Worms at MIB drinking coffee, because they are commoners.
  • Distressed Dude: In his second appearance, he has the misfortune of staying in the same hotel with a much more evil monarch, the Bug Queen, who takes him hostage and attempts to feed him to her young.
  • Must Have Caffeine: Apparently, coffee is a drink reserved only for himself and other royalty/nobility on his planet.
  • My Hovercraft Is Full of Eels: He claims to have learned English from "books on tapeworm", and greets humans with sayings like, "Greetings from my bottom!". The only phrase of English he can speak properly is "I am Large and in Charge."



(Former Agent) Alpha

Voiced by: David Warner

A rogue MIB agent who once led the organization until he betrayed them. He steals organs from aliens in order to become more physically powerful.

  • Big Bad: The most recurring and dangerous antagonist in the series.
  • Body Horror: All of his augmentations, both cyborg and biological.
  • Broken Pedestal: To Kay.
  • The Chessmaster / Evil Genius: He knows everything there is to know about the Men in Black and extraterrestrials, and is quite a cunning mastermind. He even enjoys playing literal games of chess.
  • Cyborg: He becomes this in the final season, deciding that mechanical augmentations are better than biological enhancements.
  • Deadpan Snarker: Creepy as he is, he has more than his share of amusing moments thanks to his snarky attitude.
  • Evil Brit: As usual with David Warner.
  • Evil Former Friend: Was Kay's friend until he betrayed his trust.
  • Evil Old Folks: He's an old man, and an irredeemable sociopath.
  • Evil Versus Oblivion: In the finale, he fights to stop Vangus from destroying the Earth, since its destruction would leave nothing for him to rule. Ironically, this gets him killed when he tries to disarm the missile Vangus fired at the planet, since he failed to disarm it in time, and is destroyed along with the missile when J and K blow it up.
  • Face Death with Dignity: Subverted. He is initially calm when he is stuck on the missile Vangus fires at Earth, since at least if he can't rule the Earth, nobody else will. But then he has an Oh, Crap! right before J and K blow up the missile.
  • Fallen Hero / Face–Heel Turn: The first leader of the MIB, who turned evil.
  • Faux Affably Evil: He's always polite and greets Kay as if he's still an old friend. But in reality, he's a cold-blooded and heartless monster.
  • Final Boss: Along with Vangus, he leads an Alien Invasion in the Grand Finale episode.
  • Gadgeteer Genius: Generally downplayed due to his primary interests being biological in nature, but Alpha consistently shows a startling degree of skill in the manipulation of almost any technology, whether alien or human. Even when left in a physically decrepit state with little mental stimulation for several months, he manages to escape a maximum security MIB prison cell (part of which is effectively a metal coffin) using the pieces from an electronic chess board.
  • Humanoid Abomination: Some of his augmented forms are more so than others, but they are never a pleasing sight.
  • Hybrid Monster: He was born human, but has attached so many different alien body parts that he barely qualifies as one anymore.
  • Immortality Seeker: He wants to cheat death, and accomplishes this by removing some key organs from aliens with indefinite lifespans.
  • Joker Immunity: At the end of each of his appearances, he is seemingly killed in action or otherwise defeated, only to return again and again to cause more trouble. He finally meets his actual demise in the final episode, when Agents J and K blow him up with an intercepted missile.
  • Knight of Cerebus: The tone always darkens and the stakes are raised whenever he's present.
  • Organ Theft: His Evil Plans usually involve stealing body parts from aliens.
  • Manipulative Bastard: He secretly toyed with Agent Kay and the rest of the Men in Black, as part of his sinister schemes to steal the Cosmic Integrator and sell out Earth to an alien empire. Much later in the series, he tricks Agent Jay into giving him some improvised tools to escape from his MIB prison cell.
  • Pupating Peril: "The Quick Clone Syndrome" reveals that Alpha has been recovering from the injuries he suffered back in his first episode by wrapping himself up in a cocoon deep in the sewers. Having transformed into an even less human shape in the intervening time, he goes on the offensive as soon as J and K begin forcing his cocoon open.
  • Screw the Rules, I Make Them!: How he tried to justify using the Cosmic Integrator.
  • Smart People Play Chess: To the point that J bribes him to reveal information by allowing him to have an electronic chess board in his cell. Alpha reveals he is even smarter by using it to escape.
  • The Sociopath: He's a superficially charming, ruthless manipulator who was respected and trusted enough to become leader of the Men in Black, but had no qualms over backstabbing his own organization (and the rest of his own species), all for the sake of gaining more power. And of course, he doesn't care how many innocent lives it takes to become the ultimate life-form.
  • Take Over the World: His ultimate goal in the two-part finale is to enslave any and all surviving humans after the Ixion invasion of Earth is complete.
  • That Man Is Dead: According to Kay, "The Alpha [he] knew died 20 years ago."
  • Transhuman Treachery: With every alteration he makes to his body, he comes off as becoming less and less human, both literally and figuratively.
  • Treacherous Advisor: Used to be Kay's mentor.


Buzzard (Treblor)

Voiced by: Sherman Howard

A Zombarian police officer turned bounty hunter, who finds and captures other aliens on behalf of his clients.

  • Badass Longcoat: A mercenary who wears a Conspicuous Trenchcoat as a disguise, and is skilled and tough enough to fight Agent K to a draw. Though he ditches the coat when he actually starts to engage someone in combat.
  • Bizarre Alien Biology: He has three mouths and grasshopper-like, reverse-jointed legs.
  • Bounty Hunter: He's an alien bounty hunter who's paid to find and capture other aliens, no questions asked.
  • Code Name: "Buzzard"; his real name seems to be Treblor.
  • Conspicuous Trenchcoat: Makes his introduction in a noir-like black trenchcoat and fedora hat, complete with a breather mask and facial bandages. This disguise does relatively little to hide his alien features, among other things because he is still towering tall and it does not even cover entirely his skin, but it is played for creepiness rather than for laughs.
  • Evil Versus Evil: In his first episode, Buzzard was sent to Earth to track down a fugitive criminal. Buzzard lied about still being a cop, was only doing the job for money, and tried to murder Kay for getting in his way. However, he's not nearly as evil as the fugitive he was after — a vicious Serial Killer who eats other sapient aliens.
  • Lawman Gone Bad: He served in law enforcement before he found new work as an amoral mercenary.
  • Lean and Mean: Freakishly tall (mostly when outstretched, given that he usually has a crouched down stance) and very thin, and definitely not a nice guy at all.
  • Lightning Bruiser: Very fast and tough, and can perform high jumps with his long legs.
  • Real Name as an Alias: Goes under his former identity as a Zombarian law enforcement agent with his real name.
  • Sinister Shades: Wears green goggles over his eyes.
  • The Stoic: His reserved demeanor really adds to his overall creepy mannerisms.
  • One-Man Army: The guy is dangerous enough to require a literal army to chase him away.
  • What Happened to the Mouse?: The last time we see Buzzard in the series, he is zapped away by K. It is unknown if he escaped, or was captured or even killed.



Voiced by: Brion James (Season 2), Ron Perlman (Season 3)

A professional criminal who once shared a prison cell with Frank the Pug. He's a big brute who can shoot fire from his hands.

  • Ax-Crazy: He wants to burn up anyone who has ever crossed him, preferably by "boiling 'em alive" in a vat of hot liquids.
  • The Brute: He's huge, muscular, imposing, and is just as scary as he looks. However, he averts Dumb Muscle.
  • Faux Affably Evil: He greets Frank like an old friend, before threatening him due to being a snitch for the MIB.
  • Hair-Trigger Temper: He's certainly very hot-headed, both figuratively and literally.
  • Jerkass: He's an ill-tempered, violent thug who threatens and throttles even the people he considers friends.
  • Not-So-Harmless Villain: He's a dimwitted thug with odd speech patterns, but he's also extremely violent and prone to anger, making him very dangerous.
  • Playing with Fire: His hands can shoot out fireballs, and can also burn whatever he touches at will.

    Dak Jeebs 

Dak Jeebs

Voiced by: Billy West

Jack Jeebs' evil(er) brother, who briefly worked as a henchman for Alpha.

  • Alien Blood: His body fluids are also green.
  • Cain and Abel: The Cain to Jack's Abel. Downplayed because Jack himself is an amoral slimebag, though nowhere near as bad as his brother.
  • Evil Twin: Nastier than his brother (though Jack himself is very far from being a saint).
  • Fusion Dance: When Dak (and Alpha) are apparently 'killed' after the former's first appearance, they accidentally merge into a single being with two heads, much to Dak's dismay. Fortunately they're separated in the end.
  • Healing Factor: Being the same species as Jack after all, he can recover from any wounds. His regenerative abilities also apply during the time he's merged with Alpha.
  • Human Aliens: Just like his brother, he looks completely human unless splattered into green goo.
  • Too Kinky to Torture: Unlike Jack, Dak enjoys the pain of having his head blasted off and growing back.

    Edmund Clark Moffat 

Edmund Clark Moffat

Voiced by: Vincent D'Onofrio

A paranoid conspiracy theorist that turned out to be somewhat right when he accidentally discovered the existence of the MIB. He steals a time travel device to try to wipe out the original founders from existence because in his warped mind, if the MIB didn't exist then there would be no aliens on earth.

  • Former Bigot: The ending implies that he ends up becoming one of the founders of MIB through his own time travel shenanigans.
  • Heel–Face Turn: After he is beaten he is sent through a time portal. In the end, he's shown in the black and white picture of the MIB founders meeting aliends for the first time smiling. It's implied that he became one of the founders of MIB and one of the good guys.
  • Irrational Hatred: His hatred towards aliens is almost described as this word for word by Jay. While some wariness of aliens is understandable and obviously some aliens are evil, Edmund's hatred bordered on fanaticism. He truly believed by destroying MIB, no aliens would appear on earth and it never occurred to him the MIB isn't the reason aliens even come to earth to begin with. MIB is a police organization and 99% of aliens that come to earth, do so for reasons that have nothing to do with the MIB.

    The Bugs 

The Bugs (Drones and Queen)

Bug Drones voiced by: Vincent D'Onofrio
Bug Queen voiced by: Mary Kay Bergman

Giant arthropod aliens, who are the same species as (and directly related to) "Edgar the Bug" from the first movie.

  • Always Chaotic Evil: All of them are aggressive assholes who want to kill and eat other aliens or humans.
  • Big Eaters: They constantly crave after sugary food and live prey.
  • Even Evil Has Loved Ones: The Queen is absolutely pissed by Edgar's death, and orders a bounty on Agent L for the other Bugs to claim; she wants them to capture Elle alive so she can be executed by the Queen herself.
  • Explosive Breeder: The Queen has millions of offspring. She later decides to move to Earth to infest the planet with her many eggs.
  • Insect Queen: Obviously, the Bug Queen is the leader and mother of all the other Bugs.
  • Insectoid Aliens: Of course, they're a whole species of Big Creepy-Crawlies, and they even have a hive-like social structure.
  • Laughably Evil: Much like Edgar the Bug from the first film, they've got a twisted sense of humor around them.
  • Sibling Rivalry: Not all the Bugs get along with each other. Three different brothers compete to try and kidnap Elle to avenge Edgar's death, only for two of the Bugs to murder the other one. It's stated that this could cause a Civil War among their kind.

    The Fmeks 

The Fmeks

Voiced by: Unknown

A race of aggressive yet diminutive aliens from the planet Fmoo, and sworn enemies of the Arquillians.



Voiced by: Billy West

A leader of the Ixion race, who has been conspiring with Alpha for a planned invasion of Earth for the past 30 years.

  • Alien Invasion: His space fleet attacks Earth to seize the planet's oil.
  • Bat Out of Hell: Vangus belongs to a bat-like race, with a demonic demeanor to match.
  • Big Bad Duumvirate: With Alpha at the end of Season 4.
  • Evil Is Petty: Vangus attempts to annihilate all humanity out of what amounts to impatience in the end, rejecting Alpha's suggestion to extract a satisfying defeat for his enemies in prolonged conflict and instead opting to blow up all life on the surface all at once.
  • Karma Houdini: Although the Ixion military is defeated by Earth, and Alpha gets killed by Kay and Jay, Vangus himself ends up escaping unharmed, his last whereabouts unknown.
  • Knight of Cerebus: Much like Alpha, there is no humor around him, and the threat he poses is more serious than usual.
  • Planet Looters: He wants to conquer Earth, just because it's rich in oil, which is a valuable resource in the wider universe.
  • The Starscream: When the tide of war is turned in Earth's favor, Vangus grows impatient and decides to ditch the idea of letting Alpha rule over the humans, as he prepares to launch a missile that would destroy everyone on the planet while saving the oil for the Ixions.
  • Winged Humanoid: He flies around with a pair of wings.
