Tony Stark/Iron Man
Voiced by: Adrian PasdarA billionaire industrialist and a brilliant inventor in his own right, Tony Stark is the team leader. Following an incident that left him with a piece of shrapnel in his chest, Tony designed an electromagnetic harness to keep himself alive, and eventually, a suit of armor that could be powered by it.
- Aesop Amnesia: No matter how many times Tony learns that relying solely on technology will not work, he's right back to being a smug jerk who thinks his tech is infallible the very next episode. Not even the war with the Cabal did anything, as he's still bad about this well into the second season. In fact, him not learning from his mistakes is what caused Captain America, Black Widow and Falcon to quit the Avengers.
- Eventually subverted after the Avengers Disassemble arc where the following episodes show him actively addressing issues in the team's tech, which he designs himself, to improve it and even making efforts to improve team dynamics.
- Attack! Attack! Attack!: His plan to attack the HYDRA base? Hit everything hard. Later, he keeps pounding on the Super-Adaptoid while Cap's busy trying to tell him that it's not gonna work.
- Badass Bookworm: Tony Stark is a prime example of this concept.
- Big Brother Instinct: Not always apparent but this trope is there in spades. He tends to motherhen his teammates by either backseat driving (which is sometimes justified, sometimes not depending on the situation) and checking in on the others during times where he can't be there in the field, which gets lampshaded at one point. The latter is what actually opened up the pilot. He's also shown to be fairly protective of all his teammates to varying extents, and went through a HBSOD when his leadership directly caused Falcon to be severally injured and didn’t snap out of it until said Avenger had a bit of a heart-to-heart with him.
- Break the Haughty: Several episodes, but most notably in By The Numbers.
- Broken Pedestal: For Falcon; Tony lost his respect because Tony destroyed everything when he couldn't see past his own pride, which causes Falcon to join Captain America's team instead.
- Brought Down to Badass: in Exodus (part 1 of the Season finale) Tony brings all of his armors to assist the Avengers, and they all get destroyed in the process, leaving Tony without any armor. The Final Showdown (part 2) has him find a replacement in the entire Avengers Tower, and finally, an alliance with MODOK sees Tony getting back the armor Skull stole from him. When his armed fritzed out in Small Time Heroes, he had to resort to hand-to-hand combat.
- But He Sounds Handsome: Tony can't resist giving himself a pat on the back or two while disguised as the Grim Reaper and trying to infiltrate the Cabal. Comes back to bite him, though, as it makes MODOK and Skull suspicious.
- Did You Just Scam Cthulhu?: Galactus made him his herald. Tony found him a planet to eat alright.
- Divide and Conquer: He plays on MODOK's resentment and Attuma's lust for power to have them start a brawl with Red Skull at one point.
- Disability Superpower: It's hard to remember sometimes but that arc reactor in his chest is a glorified pacemaker. Remove the arc reactor and Tony's heart will very quickly give out. MODOK demonstrates this fact early on.
- Dressing as the Enemy: Disguises himself as the Grim Reaper to infiltrate the Cabal.
- Dull Surprise: Adrian Pasdar really sounds like he's not into it a majority of the series.
- The Engineer: To quote Cap:Tony's a builder. He doesn't adapt to the situation, he adapts the situation to suit him.
- Fatal Flaw: Pride. Shown in full force with his dealings with Justin Hammer. Unfortunately for the team, Red Skull has noticed this flaw.
- Fiction 500: He runs a Mega Corp., Stark Industries, and can still redirect some money into the Avengers.
- Heroic B.S.O.D.: First in By The Numbers, when his haughty dependence on his suit's probability programs ultimately lead to Skull getting his hands on The Tesseract. Then in Exodus, he gets another one when he nearly gets Falcon killed, resigning leadership to Cap.
- If My Calculations Are Correct: Tony puts far too much faith in his probability programs, despite Cap's warnings that you can't accurately predict the human element. Tony replies the human element is insignificant as a far as his calculations are concerned. When going up against a strategist of the Red Skull's caliber, this proves to be his undoing.
- It Only Works Once: Tony has a tendency to learn from his mistakes. For example, when MODOK ripped his armor apart with his mind in the first episode Tony installed psychic inhibitors afterwards to prevent a repeat of said incident. On the other hand, see Aesop Amnesia.
- The Leader: He's in this position instead of Cap, though they sometimes appear to share the role.
- Takes a 10-Minute Retirement in Exodus after being shaken by almost getting Falcon killed, handing the wheel to Cap.
- Magic Versus Science: Tony's smarter than the average Flat-Earth Atheist, acknowledging that Thor and other magical beings, Asgardians in particular, are doing something beyond his understanding. Though he refers to it as science he hasn't figured out yet.
- Macross Missile Massacre: His suit has a quite a few missile launchers in it.
- Nice Job Breaking It, Hero: Nice going with those Space Phantoms there, Tony.
- Phlebotinum Dependence: He needs that arc-reactor in his chest to suvive and is almost killed when MODOK rips it out.
- Pass the Popcorn: Tony's reaction to Cap trying out his new repulsor boots; thirty million people on Youtube in the episode agree with him.
- Powered Armor: His claim to fame.
- Reset Button Suicide Mission: In one episode, the Squadron Supreme uses the reality gem to create a reality where they're heroes and the Avengers are bad guys. Being aware of this by the time it seems he'll have to get himself killed to save the day, Iron Man does so under the expressed belief he'll be restored once the reality is restored. He's proven right.
- Science Hero: In the end, it's his science that does Thanos in, as he reprograms Arsenal to contain all 5 Infinity Stones.
- Smug Super: Tony has problems with his ego from time to time. This is because he knows he is one of the world's best inventors and never let's anyone forget that fact.
- Technology Porn: Tony loves his tech, but tends to become too dependent on it, a fact that Captain America lampshades time and time again.
- Training the Peaceful Villagers: He convinces the peaceful natives of the Savage Land to help him deal with Justin Hammer's mining operation.
- Troll: Hacks the computer systems in Doom's fortress, seizes control of his defenses....and cancels his movie subscriptions.
- He also created a nasty piece of malware that deliberately mocks Doom before shutting down his entire base.
- Walking Armory: An original poster-boy of the trope.
- Would Hurt a Child: Tony had no qualms against using his repulsors on a teenage supervillain; although he kept the blast at minimum.
- Whole Costume Reference: In "Dark Avengers", Tony undergoes a Palette Swap that makes the red in his armor black, evoking the Marvel Now armor.
Steve Rogers/Captain America
Voiced by: Roger Craig SmithA sickly young man from Brooklyn turned into a perfect soldier by a government project during World War II. He ended up frozen in ice and awoken in the modern era during a battle with the Red Skull. His weapon of choice is a Vibranium shield that can absorb all energy directed at it, making it ideal as both protection and as a projectile (as it does not lose energy when it makes contact with another surface when thrown).
- A Father to His Men: His unwillingness to take risks is what eventually breaks up the team.
- The Ageless: The super soldier serum has helped him defy Father Time, but as the Time Stone has shown, time will catch up to him eventually.
- Badass Boast: Cap gets an excellent one on behalf of the team in Thanos Triumphant.When Avengers stand, tyrants fall!
- Badass in Distress: Gets kidnapped and held hostage more than any other member of the team. First episode, Cap is apparently disintegrated, but instead kidnapped and body swapped by the Red Skull. Later, he in Planet Doom he is held as a Sealed Good in a Can by Doctor Doom And even after his great genius moment in Bring On the Bad Guys, he is defeated and held prisoner and used as a hostage against Tony by Red Skull and in the Ambassador he is briefly captured by Doctor Doom when Doom's end game comes to light. In season two, he ends up injured and unconscious trying to help kid Tony and has trouble grappling with the Red Skull.
- Beware the Nice Ones: He's one of the nicest guys in the world, but God help you if you decide to hurt his teammates.
- Also, don't let that boy scout act display fool you. It is genuine but underneath it he has a pretty devious mind; something Dr. Doom found out the hard way.
- Bodyguarding a Badass: He ends up as Dr. Doom's personal bodyguard during his attempted speech at the United Nations. Justified in that Doom went without his weapons in a diplomatic move.
- Broken Pedestal: To Spider-Man. Spider-Man always looked up to him, and Spider-Man was really hurt at the fact that Captain America quit the Avengers, which goes against everything Spider-Man learned from him.
- Captain Patriotic: The Trope Codifier.
- Comic Book Fantasy Casting: Like in Ultimate Spider-Man, Roger's channeling Chris Evans.
- Disney Death: In the pilot.
- Dressing as the Enemy: He makes a pretty good imitation of Crossbones.
- Empowered Badass Normal: No actual super powers aside from his superhuman physique, and he started out as a scrawny kid before becoming a Super Soldier.
- Foil: To Tony.
- Genius Bruiser: Steve has intelligence to complement his physical ability, which is on full display in "Super-Adaptoid".
- Good Is Old-Fashioned: But not obsolete as shown in "Super-Adaptoid".
- Hair of Gold, Heart of Gold: Blond haired and blue eyed, he is also a old-fashioned good guy.
- Incorruptible Pure Pureness: Best shown in The Dark Avengers, wherein reality has been altered and he'd been turned into a super-villain. From the get-go he can tell something's not right, and unlike the rest of the Avengers, never actually does anything that could be considered villainous. He also sees through Thanos' use of the Reality Stone just as easily.
- The Infiltration: He is the one who came up with the plan of him and Stark infiltrating the Cabal by disguising themselves as Crossbones and Grim Reaper.
- The Lancer: Could be seen as this to Iron Man/Tony Stark, until he decides to quit.
- The Leader: He used to the leader of the Avengers until he passed it on to Stark. He took over as leader of the team in the end of Season 1 when Tony suffered a Heroic B.S.O.D.. Finally, he becomes leader of his own team when he quit the Avengers and took Falcon, Hulk, and Black Widow with him.
- Luckily, My Shield Will Protect Me: Averted in the first episode.
- Never Tell Me the Odds: He tends to view Tony's probability and strategy programs as fairly useless; preferring instead to rely on gut-instinct, training and experience.
- Nice Guy: He's a gentle and caring man who always does the right thing.
- The Not-Love Interest: to Tony. His faked death in the first episode was the catalyst that had the Avengers get back together again, and acts as a stabilizing influence on Tony for the rest of the series.
- Shut Up, Hannibal!: Stops Hyperion's rant by throwing his shield in his face.
- Start My Own: Captain America couldn't agree with Tony Stark's selfish attitude, quits and takes Black Widow, Hulk, and Falcon with him and they all join S.H.I.E.L.D. as their own group. However, Nick Fury re-brands Cap's S.H.I.E.L.D. team as Avengers, even though Iron Man's team have claim to the name.
- The Strategist: Able to instantaneously formulate ironclad attack patterns, formations and strategies based on split second assessment of the situation compared to the abilities of the Avengers. In later eps, one starts to wonder why Tony, though brilliant, is still the leader of the Avengers when it's clear he's used to handling a solo gig and relying on algorithms to predict superhero-villain battles.
- To further highlight it, Cap tends to focus on the Big Picture while Iron Man focuses on the details. As a result, Cap knew they were in trouble in "By The Numbers" because the Hulk was injured and the Cabal was dividing them up while Iron Man kept insisting every thing was alright because his detail oriented probability program said so.
- Didn't See That Coming: His greatest (And perhaps only) flaw as a strategist, is that he's used to relatively mundane scenarios. Two teams fighting is one thing, utilization of advanced tech and/or magic can often be his blindspot. That's where Tony and Thor's aid comes in handy.
- Super Soldier: Given the super soldier serum during World War II, which is how he gets his abilities.
- Team Dad: is the Only Sane Man of the team, Widow excepted, and often has a paternal attitude to his teammates.
- Team Mom: First person to suggest training, hovers over the half-Vampire Black Widow, easily offers words of praise to Sam Wilson, checks on Hulk when he has a case of amnesia and has eaten an alien parasite and to give de-aged kid Tony a healing hug.
- Whole Costume Reference: In "Dark Avengers", he wears the uniform he wore as "The Captain" (and the one Johnny Walker uses as U.S. Agent).
Voiced by: Troy BakerAn elite agent formerly of SHIELD and ex-partner of the Black Widow. He is an expert archer and seems to enjoy egging on the Hulk.
- Annoying Arrows: some of his opponents just shrug off his arrows.
- Aesop Amnesia: The guy will never learn to stop messing around with Hulk's food. Probably because the Hulk will never stop messing around with his food.
- Badass Biker: He has a real nice hoverbike that he is typically seen riding on.
- Badass Normal: No super powers to speak of, but he's a highly trained ex-SHIELD agent and a deadly archer.
- Big Eater: Always going on about food and it's a regular source of conflict between him and Hulk.
- Brilliant, but Lazy: In "The Kids Are Alright", it's shown that he's very skilled with electronics. He admits to Falcon that he keeps this talent hidden so nobody will ask him to do stuff.
- Characterization Marches On: When he first appeared in Ultimate Spider-Man, he was serious and calculating if sarcastic and having a sense of humour. However, in this adaptation, he's still sarcastic, but he's portrayed as cocky, impulsive and somewhat immature. This could, perhaps, be explained by the fact that he doesn't feel the need to set an example around the Avengers.
- Clark Kenting: Most of the Avengers have masks; or in the case of the Hulk are mutated heavily from their normal human features; or in the case of Thor don't actually have a secret identity. Hawkeye just wears a pair of purple shades.
- However, in a recent episode, Hawkeye's purple mask from earlier incarnations shows up in a storage room in the basement of Avenger Tower. Clint seems to treat it as an Old Shame, snatching it away from Ms. Marvel hastily and a bit sulkily.
- Complaining About Rescues They Don't Like: Falcon saves him from becoming a stain on the pavement. He immediately starts complaining about it as soon as his feet are on the ground.
- Cool Bike: Drives his own custom hover-cycle as his method of getting around, since he's the only member besides Cap who doesn't have Flight or "Super Leaping".
- Cool Shades: He's got a nice purple set. Savage shows he carries a spare pair on him at all times.
- Dark and Troubled Past: As revealed in Crime and Circuses, Clint used to be a member of the criminal group called the Circus of Crime. He tries to keep this a secret, but eventually confesses his past to the rest of the Avengers.
- Deadpan Snarker: He snarks a lot.
- Didn't Think This Through: Says so word for word when he uses his hoverbike as a kamikaze weapon against a meteorite.
- Jerk with a Heart of Gold: Hawkeye is frequently seen heckling and ticking people off, but there's no doubting the good heart he has deep down.
- Handicapped Badass: After being temporarily blinded by the Cosmic Skull during the season 1 finale.
- Heel Realization: He realizes that sometimes he takes things too far in his dealings with Mojo.
- Improbable Aiming Skills: many of his shots are objectively impossible.
- Improbable Use of a Weapon: He's more than capable of using his bow and arrows as close-quarters weapons.
- My Friends... and Zoidberg: He doesn't get treated like this by the Avengers themselves but chances are if he ends up in space for any amount of time he'll get very little respect from those outside the team or no one will even know who he is. This possibly has something to do with his Memetic Loser status among the MCU fanbase.
- Mythology Gag: Temporarily became giant in size during "One Small Problem" as a callback to Clint's brief career as one of the Goliaths.
- Sarcastic Devotee: Pretty much to everyone he's on the team with.
- Ship Tease: Gets a little bit of this with Natasha during Beneath the Surface.
- Sleeves Are for Wimps: His default outfit is sleeveless.
- The Straight and Arrow Path: Like all versions of Hawkeye, he favours the use of bow and arrow.
- Too Dumb to Live: Hawkeye is in a fight with Hulk. Iron Man and Captain America step in as Reasonable Authority Figures, ready to set them apart and stop the fight. But when they hear that Hawkeye broke one of Hulk's glass figurines, they rolled their eyes and accepted that Hawkeye is simply willing to die.
- Trademark Favorite Food: He sure likes his pickles.
- Vitriolic Best Buds: With the Hulk.
- Whole Costume Reference: Hawkeye wears his Darker and Edgier costume from The Ultimates 3 in "Planet Doom".
Voiced by: Travis WillinghamThe Norse God of Thunder who believes that by acting as a hero on Earth, he can make more of a difference.
- Badass Baritone: possessed of a suitably deep voice.
- Badass Beard: as an old man, he'll have one.
- Badass Grandpa: briefly under the influence of the Time Stone, when he grows a Badass Beard and informs Thanos that age only makes Asgardians more powerful, before forcing the Time Stone's effects back on Thanos.
- Bash Brothers: with the Hulk.
- Berserk Button: Messing with his cape seems to be an open invitation for an ass-kicking.
- The Big Guy: The tallest of the Avengers right after Hulk.
- Boisterous Bruiser: Thor likes a good time; in the first episode, he's excitedly telling Hawkeye about an Asgardian festival he was missing out on. Then there's the time he and the Avengers went to a diner after defeating Hyperion.
- When we finally meet his dad, Odin, we see were he got it from.
- Cain and Abel: The Abel to Loki's Cain.
- Chekhov's Gun: He loses Mjolnir during the first half of "The Final Showdown". It gets back to him during the climax, just in time to stop the Red Skull from killing everyone by knocking him and the Tesseract into a portal.
- Deadpan Snarker: while he doesn't do it anywhere near as often, he's by far the most deadpan member of the team, making it all the funnier when it does happen.
- Dumb Jock: In the episode Back to School we learn Thor never graduated school or the Hall of Learning. He did poorly compared to Loki who excelled and was pulled out by Odin to "help" on the battlefield because Odin did not think he could pass the final tests. While he does eventually pass and "graduate" it took a lot of help and Thor still tends to make dumb mistakes that others call him out on.
- Dumb Muscle: Thor in this show can be surprisingly reckless and dense to the point the Hulk has to point things out to him.
- Drop the Hammer: He wields his mystical hammer, Mjolnir in battle, and can summon thunder and lightning. Apparently, it's powerful even when shrunk.
- Elemental Powers: Wind and lightning.
- Flying Brick: though he seems to throw Mjolnir and hold onto its handle, flight is the only way to describe what he does. The Brick part goes without saying.
- Godzilla Threshold: The Destroyer poses enough of a threat that bringing in Loki is the best idea that Thor can think of.
- Hair of Gold, Heart of Gold: Has long blond hair and is an Avenger.
- Immortal Immaturity: Despite being over a thousand years old Thor is very reckless and is often more concerned with proving himself in battle and having a good time then considering the consequences of his actions. He has at times summoned storms or insisted on engaging the Hulk (Or others) in battle to prove who is stronger despite the damage it causes or the people it puts in danger. Hulk And The Agents Of SMASH time-traveling episode showed Thor has physically grown up while still being as reckless and immature as he was in the Viking Age.
- Large Ham: often very loud and very enthusiastic, to go with his Boisterous Bruiser tendencies.
- Magic Versus Science: Engages in back-and-forth needling with Tony over this.
- Meddling Parents: Thor's dad, Odin, has a tendency to dictate how his son should live his life, much to Thor's displeasure.
- Mundane Utility: Lightning powers are also good for making popcorn and bar-b-que in addition to zapping bad guys.
- Physical God: He's the god of thunder, so that's given.
- Set Right What Once Went Wrong: Because he was in Asgard, and therefore in a different dimension, when Doom fired up his time machine in Planet Doom it is up to Thor to restore the timeline to it's original state.
- Shock and Awe: He is the God of Thunder, after all.
- Stronger with Age: Asguardians as a whole get more powerful when they age. Because of this, Thanos' attempt to use the Time Stone on him backfires spectacularly.
- Strong Family Resemblance: When aged by the Time Stone, he quite heavily resembles his father, beard and all.
- Superheroes Wear Capes: the only member of the Avengers to play this straight, which leads to occasional mockery from his teammates.
- Hyperion's impressed, though, enough that he nicks the cape. Thor takes it back by force.
- Super Strength: He's strong enough to go toe to toe with the likes of Hyperion, the Hulk and Thanos Hulk, Hyperion and Thanos. He can even hit hard enough to launch the Hulk from the Moon back to Earth and give Hulk amnesia (admittedly, Hulk let him do so, as it was the only means they had of getting help from Earth).
- When he cuts loose, the side effects of his blows cause fully fledged tidal waves.
- Vitriolic Best Buds: With the Hulk.
- Worf Barrage: Thor will sometimes summon an all-powerful lighting attack meant to atomize the enemy only for it to fail to scratch them. One stand out case is the first battle against the Super-Adaptoid.
- Worf Effect: Thor is supposed to be around the Hulk's strength, with vast weather powers and Asgard's greatest warrior. Yet he is constantly overpowered by villains and needs saving by the other Avengers.
- This is generally averted from season 2 onwards, especially in Thanos Triumphant, when Thanos smacks him into the Moon hard enough to leave a crater at least he size of the US in its surface. This only serves to annoy him. The prospect of his counter strike scares Thanos, who it should be noted was wearing the Infinity Gauntlet at the time and had shrugged off blows from the Hulk, enough that he resorts to using Black Widow as a human shield. Furthermore, he's the only one who actually manages to directly turn one of the Infinity Stones against Thanos.
- Ye Olde Butcherede Englishe: His speech pattern.
- You Can't Fight Fate: Has this attitude to begin with, but he abandons it later on.
Voiced by: Fred Tatasciore, Jesee Burch (Bruce Banner, Season 3)He's big, green and likes to punch things. What more needs to be said? Formerly Bruce Banner, a leading scientist in the field of gamma radiation, he developed an alternate personality that manifested as the rampaging monster known as The Hulk after being mutated by said radiation.
- Attack! Attack! Attack!: His battle plans consist of punch everything hard.
- Badass Baritone: the deepest voiced Avenger.
- Berserk Button: Don't mess with the Zoo (the in-series name for his glass figurine collection).
- Or take his peanut butter. Or cereal, or guacamole, or any of his food in general. Hulk almost lost it when Falcon stole his sandwich, but Falcon lucked out because the sandwich landed on Hulk's hands,
- Trying to prank him is a bad idea too.
- Seriously hurting Thor really pisses him off as well.
- Big Eater: He eats a lot of food, which is justified in Hulked Out Heroes as being a side-effect of his mutation; a Hulk's body is a living bio-nuclear reactor, so it needs a lot of fuel to work.
- The Big Guy: Shares this role with Thor, and they often fight over the position.
- Blood Knight: He's one of the most eager members of the team to fight, and happiest when he is fighting.
- Cloudcuckoolander: When Hulk is in a good mood, that is.
- Comedic Sociopathy: with Hawkeye usually on the receiving end.
- Deadpan Snarker: has a surprisingly dry wit for a green rage monster.
- Destructive Savior: He arguably does more damage then the villains half the time. Ironically, when he left the Avengers with Cap, Black Widow, and Falcon, the Avengers end up doing even more damage without him.
- Easy Amnesia: He ends up suffering a bout of this thanks to Thor and his hammer.
- Genius Bruiser: Though he doesn't often show it, he retains Banner's intelligence. He emphasizes that he's only angry, not stupid.
- When Widow's in his body, he tells her that it's best to break through doors leading with the shoulder, not the head.
- Guttural Growler: As is common to film and animated depictions, he speaks in a very deep, guttural, growling tone of voice.
- Hair-Trigger Temper: Zigzagged; he does get angry very easily (as you'd expect of The Hulk), but he normally doesn't get physical unless he's really steamed or he's supposed to be fighting the guy ticking him off anyway.
- Heel Realization: He does realize, somewhat, that he isn't the best roommate in the world in Hulked Out Heroes.Hulk (as Hulk!Thor runs off all pouty): So that's what it's like to live with me. (Beat) I'd hate living with me.
- Hidden Depths: His friendship with Glorium, being bowling buddies with The Thing, his glass figurine collection; these are not exactly things you would typically associate with a big gamma radiation-powered Blood Knight.
- Hulk Speak: Averted, much like in Earth's Mightiest Heroes.
- However, the more pissed off he gets, the more likely you are to hear Hulk Speak, rage apparently eroding his intelligence. (This, by the way, is when you want to run for your life.
- We also get samples of this in Hulked Out Heroes when the Avengers are exposed to a virus that makes the like the Hulk.
- I Love Nuclear Power: How he became what he is in the first place.
- In a Single Bound: He shows he can jump from the streets of Manhattan to the top of sky-scraper and then through Glorium's portal which is miles up.
- Odd Friendship: With Glorium, a master Asgardian craftsman. He respects his ability to smash, and Hulk likes his glass figurines.
- One-Man Army: What else would you expect of the Hulk?
- Power Glows: When he gets really angry and really strong, he starts glowing green.
- Real Men Wear Pink: You wouldn't expect a guy like him to collect glass figurines, would you?
- Security Blanket: Hulk loves his glass figurines.
- Super Strength: The most physically powerful of the Avengers (just about - Thor runs him close) and capable of, when going toe to toe with Hyperion, 'shaking continents'.
- Status Quo Is God: No matter how many times Hulk becomes Bruce Banner, he'll always revert back to being Hulk.
- Through His Stomach: Falcon gains his friendship through his mother's cookies, Ant Man does so by bringing a mini-party, and enlarging a slice of cake before he eats it. He even joins Cap's team over the team he better meshes with because Falcon does so.
- Trademark Favorite Food: He has a thing for peanut butter.
- Too Spicy for Yog Sothoth: When Dracula bites him, turning him into a vampire and gaining his abilities. Turns out Gamma Radiation has an effect similar to, if not more deadly, than sunlight.
- Took a Level in Kindness: By the time the events of Hulk and the Agents of S.M.A.S.H. come around, he has tempered his anger and anti-social behavior considerably. This doesn't really bleed into his current interactions with the Avengers though. Apparently the clashing egos and assumption that he's just Dumb Muscle brings out the worse in him.
- Hints of his later actions are shown in "Hulked-out Heroes". He's the relatively calm straight man in the latter series because he has the most control over being a Hulk. Having to deal with other, less in-control Hulks brings out his calmer side.
- Unstoppable Rage: When driven to a state of hyper-rage by Attuma, Hulk not only lifted the island of Manhattan, but easily defeated the previously unbeatable Attuma. In Season 2, he overpowered Thanos when Thanos used the Infinity Gauntlet to increase the Hulk's rage.
- Vitriolic Best Buds: With Hawkeye, Thor and The Thing.
- Season 2 emphasizes the friendship between Hulk and Thor more.
- World's Strongest Man: Hulk is constantly the go to guy for strength and when super-enraged lifted the island of Manhattan and easily overpowered Attuma underwater despite Attuma earlier easily overpowering Thor and matching the Hulk blow for blow on the surface.
- Worthy Opponent: Odin of all people sees him as this.
Natasha Romanoff/Black Widow
Voiced by: Laura BaileyAn ex-Russian spy, Hawkeye's former partner and an elite operative for SHIELD.
- Action Girl: not immediately shown as such, but gets to shine.
- A Day in the Limelight: "Widow's Run" revolves around her attempts to hide the Infinity Stones from an entire universe full of people wanting to get them.
- Ascended Extra: She was largely absent for most of the first season. She's a regular in the second, appearing in all episodes to date.
- Badass Normal: superhuman or not, trying to fight her is a bad idea.
- Beauty Is Never Tarnished: she usually looks just fine.
- Deadpan Snarker: one of the most prolific on the team.
- Determinator: Refuse to give in to the Infinity Stones' corruption, only using the stones power to help her teammates fight against Dormammu.
- Flying Car: She owns one.
- Huge Guy, Tiny Girl: She's in platonic examples of this with Thor and Hulk, as they're very close friends and confidantes. Hulk in particular is very kind to her, a far cry from his Vitriolic Best Buds shtick with Thor and Clint. She outright trusts Thor to kill her if she's overcome by the Infinity Stones.
- Ms. Fanservice: She did have her moments in season 1, but the 2nd season version is definitely this.
- In the second season, she has long,beautiful hair, a curved eye shape, Her body shape has even improved too. Through her Spy-Cat suit(which has an improved design), her entire body shape, physique and appearance are shown to be more curvaceously muscular and attractive than her season one appearance.Her arms are slightly more muscular, Her legs are also shown to be more curvaceously muscular through her 2nd season costume.
- In "Beneath The Surface," Widow (along with Hawkeye) wears an aquatic version of her costume that is very different from her main costume. but just like her 2nd season costume, the suit presents her attractively curvaceous body.
- Mother Russia Makes You Strong: Possibly averted. While it can be assumed that she's Russian (and she can clearly speak the language), unlike her counterpart in Earth's Mightiest Heroes, she doesn't have the accent and doesn't make any reference to her past. It's entirely possible, however, that considering the vague link between the two shows that she might simply have ditched it.
- Offhand Backhand: Casually backhands a mook trying to get the drop on her while chewing Tony out.
- Out of Focus: Of all the Avengers she has had the smallest role, and aside from a few spotlight episodes, she's been a minor character with little attempts to flesh out her character. Though an attempt to hand wave it has been made by saying she works with SHIELD a lot, she's so inessential to the show that she's absent for the jarring majority of the first season and is mostly kept out of the action of the season finale. Finally averted in the second season when she's made a major character. Since she resigned from SHIELD after Ultron was defeated, she can be with the Avengers more.
- Red Is Heroic: she has red hair and she's a hero.
- Secret Keeper: Trusted by Hulk with the knowledge of the Gamma Sapper Gloves.
- Ship Tease: She's a bit… playful with Hawkeye during Beneath the Surface, casting lingering gazes at various couples while scoping out for HYDRA agents.
- Spy Catsuit: Lampshaded by Thor when he's in her body, when he questions how the hell she does anything in her tight suit.
- She's Got Legs: There were moments in season 1 when she is shown to have a leggy figure.
- This trope is this in season 2. Especially when she was setting her curvaceous body on a chair and crossing her curvaceously muscular legs while interrogating the Red Skull.
- The Stoic: Deadpan Snarker tendencies aside, she's very level-headed and serious. This proves to become extremely important at the end of the first half of the second season when she's the only one in the universe besides the Sorcerer Supreme himself who can wield the Infinity Stones relatively safely and resist their temptations.
- The Smurfette Principle: Is currently the only female Avenger . . . and was the only female character in the show until very late into the first season.
- Transhuman Treachery: Leads Dracula's troops against the team after being bitten.
- Whole Costume Reference: She wears the costume and mask of longtime Iron Man foe Madame Masque in "Planet Doom".
Sam Wilson/The Falcon
Voiced by: Bumper RobinsonFormer SHIELD recruit and naive newcomer to the team. Tends to act like a fanboy around the other heroes.
- Adorkable: He's a superhero fanboy and he brings the team cookies that his mom baked.
- Audience Surrogate: He acts as a stand-in for the audience.
- Badass Normal: Like Tony, he's an ordinary human relying on a Stark-designed high-tech combat suit.
- Be Careful What You Wish For: He wanted to see dinosaurs in Savage. Well, he got his wish...
- Black and Nerdy: The only black member of the team, and a tech expert smart enough to impress Stark.
- Clothes Make the Superman: Wears a winged flight suit.
- Feather Flechettes: his standard weapon.
- Flight: thanks to the Falcon sit.
- Gadgeteer Genius: Becomes his main characterization in season 2. Compared to Stark, Falcon's inventions tend to be smaller, but fulfill more specific functions. He basically becomes the team's Batman.
- The Knights Who Say "Squee!": He was a big Avengers fan before becoming one himself (he still is even after joining the team). He also fanboys over Hyperion until his true colors come out.
- Mistaken Identity: He saves a kid from Hyperion, the kid says "Thanks, Hawkeye" before running away, much to Falcon's dismay.
- Naïve Newcomer: Made fun of frequently too.
- Screw This, I'm Outta Here!: In response to watching the Hulk and Hawkeye tearing apart the Tower in one of their fights he looks across the hall at Captain America, says "This is your problem, Captain Hall Monitor" and goes back to bed.
- Underestimating Badassery: The Space Phantoms found out the hard way that there's a reason Tony picked him for the team.
- Whole Costume Reference: He wears the costume of his Ultimate Marvel counterpart in "Planet Doom", which is weird that it isn't the default costume as the show otherwise is known for taking after the Marvel Cinematic Universe and the MCU!Falcon wears costumes based on the Ultimate outfit as opposed to the classic white and red costumes.
- Younger Than They Look: He's stated to be seventeen, yet has the same build than an adult character.
Voiced by: Grant GeorgeNewest member of the Avengers, having joined during the Ultron crisis.
- Ascended Extra: He appeared in a single episode in Season One, but then joined the team for real in Season 2. His membership even carries in to Ultimate Spiderman.
- Composite Character: He's Scott Lang, but his science background and mastery of Pym Particles are more in line with the original Ant-Man, Hank Pym. Word of God is that this was intentional, as he was conceived as a composite of the various Ant-Men from the comics.
- The Eeyore: Whenever something unlucky happens to Ant-Man, he tends to sulk about it. For example, when an unstable Pym-Particle hit him, he does nothing but sit on a molecule and mopes over the fact that he can't regrow himself.
- Horrible Judge of Character: Before joining Avengers, he made tech for a lot of supervillains and seemed to be unaware that his employers were dangerous.
- No Social Skills: Downplayed. Hawkeye aside, he can get along more or less fine with the other Avengers, but it's mentioned he tends to not get very informed about the superhero community, and often prefers the company of his ants over humans.
- Put on a Bus: In the Season 3 premier, it's stated that Ant-Man went solo from the team sometime after the battle with Thanos, as no one thought there was any threat that warranted the full strength of the Avengers. Only time will tell when he'll come back given what has happened.
- Sixth Ranger: Becomes this to Iron Man's Avengers since Captain America's team have split and became S.H.I.E.L.D.'s Avengers. After beating M.O.D.O.K., Ant-Man makes it clear he's gonna be around for a little while.
- After Ultron was defeated, and the Avengers back together, Ant-Man is a full member now.
- Sir Not-Appearing-in-This-Trailer: Curiously, despite confirmation that he's still part of the show, he is not featured on the poster for Season 3.
- Size Shifter: He can either make himself larger or smaller with the Pym particles.
- The Smart Guy: As the second full Science Hero on the team.
- Taking the Bullet: Ant-Man jumps and saves Mrs. Wilson from an unstable Pym Particle. Unfortunately, the unstable particle overrode his stable ones, making him unable to size himself back up.
Voiced by: Drake BellHigh School Student, SHIELD agent, and Reserve Avenger, Peter Parker, a.k.a Spider-Man, is one of the Hulk's best friends.
- Animal-Themed Superbeing: Spider, as usual.
- Ascended Extra: He has a much larger role in Avengers Disassembled.
- Bunny-Ears Lawyer: He narrates his adventures and is prone to daydreaming and goofing off in the heat of battle. Despite this, he's a highly skilled super hero and Iron Man's first choice to replace Captain America. He's also quick to notice and identify the problems with Cap and Iron Man's plans.
- Butt Monkey: His introduction in the show is working as a street vendor to pay for the thousand or so hot dogs the Hulk ate and left Spidey with the bill for.
- Breaking the Fourth Wall: In the same manner as he does in Ultimate Spider-Man, where he explains certain situations and elements as well as what goes on in his mind in relation to that situation.
- Determinator: Spider-Man was the only hero not trapped and who still held out when The Squadron Supreme took over Earth and presumed the Avengers dead.
- Flanderization: In Avengers Disassembled, most of the Ultimate Spider-Man traits (the chibi sketches, Spidey's narration telling us things we should be able to tell through the action and characterization, the wide eyed monkey-screech) are on ramping up, ironically at the same time when these traits have been toned down in its own series.
- Guns Akimbo: Wields a pair of high tech pistols in Planet Doom.
- Hero of Another Story: Specifically for Ultimate Spider-Man.
- Honorary True Companion: Just like Ant-Man, he's a reserve member of the Avengers whom Iron Man can call in if necessary. He's not officially a member, but he's treated as one nonetheless.
- Super-Deformed: His Chibified self from his Imagine Spots taken from Ultimate Spider-Man are used in his second official appearance.
- This Looks Like a Job for Aquaman: Spidey is the only other hero whom Adaptiod can't adapt to.
- What the Hell, Hero?: Gives this to both Iron Man and Captain America for the way they've been acting. Spidey calls out Iron Man for being a terrible leader, and Captain America for quitting the team and going against everything he taught him.
- Whole Costume Reference: He wears an outfit based off his Noir incarnation in "Planet Doom".
- Badass Crew: Obviously.
- Bash Brothers: Groot becomes this with Hulk.
- Cameo / Early-Bird Cameo: Star-Lord makes an early appearance in Mojo World watching Mojo's bloodsport on TV with Impossible Man.
- Characterization Marches On: When they return in Season 2, their appearances have been dramatically altered to resemble the depictions of the characters seen in the movie, and how they appear in their series, as well as any subsequent appearance they make in the other Marvel Animated series. Their personalities have also undergone overhauls, as now they bicker as they did in the film, and they're much more light-hearted as opposed to their all-business nature they had in Season 1. Rocket's also picked up his film incarnation's "humie" moniker.
- Fantastic Racism: Rocket makes no secret of his contempt for humans and humanity in general.
- Flat Character: Surprisingly, all of them, despite being the centerpiece of an entire episode. Especially Drax and Gamora.
- Hero of Another Story: They are the guardians of another galaxy, after all.
- The Lancer: Rocket to Star-Lord.
- Remember the New Guy: Thor already knew who they were, but we find out how he met them in their self-titled series.
- Wolverine Publicity: Their roster and appearance was clearly meant to advertise the then-upcoming film.
- Voiced by: Jack Coleman
- Early-Bird Cameo: Like the Guardians of the Galaxy and Ant Man before him, he makes his debut in the series quite some time before his MCU film was released.
- Guest Star Party Member: To the Avengers during the Infinity Stone crisis.
- It Has Only Just Begun: If the Guardians of the Galaxy's presence on Earth wasn't proof enough, Strange makes it very clear that the recent activity regarding the Infinity Stones has brought the universe's eyes to Earth.
- No Sell: He's immune to the corrupting nature of the Infinity Stones.
- Refuge in Audacity: He fights enemies like Dormammu on a regular basis, and where does he shack up? A normal New York apartment.Clint: In New York, nothing's normal.
- Adaptational Heroism: Black Bolt, at least regarding the show's version of Inhumanity. In the comics, Black Bolt was completely aware that there were human/Inhuman hybrids all around the world, and purposefully unleashed the Terrigen Mist on the world in order to transform them, without any care about the consequences. In the show, it's implied that most of the Inhumans were unaware of the hybrids before meeting Inferno, and it's actually the Avengers who end up releasing the Mist as a last ditch effort to thwart Ultron.
- Awesomeness by Analysis: Karnak can see the weakness in anything, and then attack it.
- Badass Normal: Karnak is the only member of the team without any powers, and he does just fine without them.
- Fantastic Caste System: The Alpha Primitives are a slow-witted slave race that serve the other Inhumans.
- Fantastic Racism: They initially view ordinary humans with distrust and contempt. A large part of their character arc involves them coming to trust humans and build a bridge between the two species.
- Floating Continent: Attilan, though it later is brought down to Earth by Ultron.
- Happily Married: Black Bolt and Medusa. When the members of the royal family are kidnapped by Ultron, it is implied that Black Bolt is most concerened for Medusa.
- Make Me Wanna Shout: Black Bolt's strongest ability is his highly destructive voice, which is why he rarely speaks.
- Royals Who Actually Do Something: The members of the royal family are all skilled combatants and have no problem fighting their own battles.
- Prehensile Hair: Medusa's primary power.
- Smug Supers: They are very arrogant and view themselves as being above normal humans.
- The Voiceless: Crystal and Triton appear, but have no lines.
- Voiced by: Antony Del Rio
- Bash Brothers: With Ms. Marvel.
- Breath Weapon: He can literally spit fire.
- Personality Powers: He wields fire and has a very firey temper.
- Playing with Fire: His primary power is generating flames from his body.
Kamala Khan/Ms Marvel
- Voiced by: Kathreen Khavari
- Ascended Fangirl: She was a big fan of the Avengers long before she ever got her powers.
- Early-Bird Cameo: She has a non-speaking cameo as a civilian in "The Inhuman Condition" before she actually becomes Ms. Marvel.
- Invocation: She shouts "Embiggen!" before using her powers to grow.
- The Knights Who Say "Squee!": She geeks out over meeting Iron Man and Captain America, and even gets to take a selfie with the latter.
- Rubber Woman: She's able to stretch and grow her limbs.
- Scarf Of Ass Kicking: She wears a rather long one as part of her costume.
- Voiced by: David Kaye
- Ascended Extra: He's a guest star in Season 3, but becomes an official Avenger in Season 4.
- Emergent Human: He is a Synthezoid still learning to adapt to humanity. In fact, his debut episode involves Thor trying to teach him the concept of friendship.
- Flying Brick: He possesses both flight and tremendous strength.
- Frickin' Laser Beams: He can fire one out of the gem in his forehead.
- Humans Are Special: This belief is a major part of the reason why he defends the world against Ultron.
- Innocently Insensitive: He sometimes comes off as rude or uncaring, but in reality, it's just his programming.
- Intangible Man: He can phase through objects.
- Literal-Minded: He has trouble grasping sarcasm and certain turns of phrase.
- Remember the New Guy: He shows up with no origin story given, and the Avengers are already familiar with him, and he has been helping them from the sidelines.
Carol Danvers/Captain Marvel
- Voiced by: Grey Griffin
- Adaptation Distillation: The long (and somewhat confusing) history of the Captain Marvel mantle isn't mentioned in the show. As far as the audience knows, Carol is the first and only Captain Marvel, and never used the Ms. Marvel identity.
- Adaptation Personality Change: She's much more arrogant, condescending and combative than her comic counterpart is usually depicted as being.
- Alien Abduction: How she got her powers, being experimented by the Kree.
- Ascended Extra: She's a guest star in Season 3, but joins the team for real in Season 4.
- Boisterous Bruiser: A rare female example. She proudly recounts her past triumphs to Falcon, much like Thor is fond of doing.
- Captain Superhero: She's the show's other Captain.
- Collapsible Helmet: She has one built into her suit.
- Early-Bird Cameo: She first appeared alongside Black Panther on a computer screen in the Season 2 finale. She was also referenced in the Halloween episode in Season 3, with several young girls shown dressed as her.
- Flying Brick: She can fly, has super strength, and can fire energy blasts from her hands.
- I Work Alone: She initially doesn't have much use for the Avengers, arguing that they'd only slow her down or get in her way. However, she ends up changing her mind after she realizes she needs to work with them to save Earth from a Kree plot. At the end of her debut episode, she accepts an offer to become a reserve Avenger.
- Interservice Rivalry: As a former member of the air force, she frequently clashes with Captain America, who is a former member of the army. She does later concede that the air force wouldn't be effective without the army, and vice versa.
- Military Superhero: Used to be in the air force, and mentions being on a mission from the National Security Council.
- Remember the New Guy: Most of the Avengers already know who she is when she first appears, though Falcon hadn't yet met her in person. She even has an intense rivalry with Captain America that had never been mentioned prior to that point.
- Took a Level in Jerkass: As mentioned above, her comic counterpart usually isn't this rude or arrogant.
- Voiced by: James C. Mathis III
- Absurdly Sharp Claws: Built into his vibranium suit.
- Animal Themed Super Being: His costume and powers are based off his namesake animal.
- Ascended Extra: He was initially a guest star in Season 3, but becomes an official member of the team in Season 4.
- Bodyguard Babes: The Dora Milaje, his personal squad of all-female bodyguards.
- The Chains of Commanding: Thor says T'Challa is not a naturally cruel or mean individual, but that being the ruler of an entire nation puts him under a lot of pressure and causes him to have to make a lot of difficult choices.
- Damning With Faint Praise: He's insulted when Tony says that Wakandan tech is as good as the kind made by Stark Industries. In T'Challa's mind, Wakandan tech is far superior.
- The Chessmaster: He steals Captain America's shield in order to lure Klaue to Wakanda, knowing that the smuggler won't be able to resist it.
- Dark Is Not Evil: He wears a dark costume and has "Black" in his name, but he's one of the good guys.
- Early-Bird Cameo: He was first seen on a computer monitor in the Season 2 finale.
- Hidden Depths: Thor suggests that he's a much kinder person than he lets on.
- I Work Alone: Like Captain Marvel, he's initially wary of the Avengers, as he thinks of them as little more than a bunch of bickering children. And also like her, he changes his tune after working with them and getting to see how competent they truly are.
- Jerkass Façade: He's not as mean as he comes across, but appearing so makes his job much easier.
- Legacy Character: The Black Panther identity has been passed from warrior to warrior throughout history. T'Challa inherited the mantle after the death of his father.
- Made of Indestructium: His suit is made of vibranium, the same metal used to make Captain America's shield.
- Royals Who Actually Do Something: He runs Wakanda, but that doesn't stop him from kicking ass in the field.
- Super Senses: He has enhanced senses similar to those of a jungle cat.
When the Avengers beat him one time too many, Red Skull, then allied w/ith MODOK, decided to fight fire with fire, and sent invitations to several of the world's greatest super villains. Citing great respect for his fellow villains, he invited them to join him to form the Cabal, a coalition of villains who are all Big Bad's in their own right, as well as their armies and resources. Over the course of the first season, the Cabal comes together, proving themselves as a capable threat not just to the Avengers, but even to non-aligned super villains as well. However, upon Red Skull's betrayal, the Cabal has splintered even under MODOK's leadership.
- Aborted Arc: When MODOK took control of the group at the end of the first season, it seemed the Cabal would remain major antagonists in the second season. It's gradually and casually revealed that the Cabal disbanded off-screen, almost as an afterthought.
- Arc Villain: For the first season. Beneath the Surface reveals that the Cabal fell apart after Skull's defeat. After this, they each appear separately, only making occasional contact with one another.
- Avengers Assemble: They have their own counterpart to the classic Avengers battlecry.Red Skull "Cabal! To me!"
- The Bad Guy Wins: They got better and better at this as the first season went on. Their biggest victory was taking the Tesseract.
- Big Bad: They're the primary villains of the first season, at least until Thanos shows up.
- Big Bad Ensemble: They're in direct competition with Doom during the first season.
- Breaking the Fellowship: The group disbanded sometime after Skull's defeat. HYDRA is still allies with Attuma and his followers.
- Enemy Mine: None of them really like each other, but Skull has managed to convince them to trust each other enough to form a competent team. In the first season finale, they banded together with the Avengers to defeat the Cosmic Skull.
- Equal-Opportunity Evil: Their numbers are made up of vampires, Atlanteans, Nazi's, giant floating heads stuck in a chair, aliens, and androids. Safe to say no one is getting turned away because things like race or gender anytime soon.
- Evil Versus Evil: Not just against Doom but practically every other villain who is not among their number.
- Five-Bad Band: During season one.
- Big Bad: Red Skull.
- The Dragon: MODOK.
- The Brute: Attuma, and also MODOK when piloting the Adaptoid.
- The Evil Genius: MODOK, but also Dracula, the Only Sane Man amongst the group.
- The Dark Chick: Hyperion, who while loyal to the team, is always absorbed in his own ego, rather than the Cabal's cause.
- Know When To Fold Them: The group knows when to leave the fight for another day.
- Large Ham: All of them to one degree or another, bar Hyperion.
- Legion of Doom: Natch.
- Not-So-Harmless Villain: Despite a less than auspicious start, their numbers swelled and their powers extended from just science to the supernatural and undead as well. The Avengers realize they've underestimated how powerful the Cabal really is during an infiltration early into the season, while Doom realizes it later, openly asking the United Nations to stand with him against the Cabal to defend Latveria.
- The Psycho Rangers: The team in general is an Evil Counterpart to the Avengers, but to get more specific:
- Red Skull to Iron Man - the leaders of their teams, who tend to lose their heads when they gain the upper hand. Skull when in smart mode is also one for Cap, since they're both highly intelligent, pragmatic leaders.
- Dracula to Thor - Both are the supernatural powerhouses of their respective teams.
- Attuma to Hulk - The Blood Knight's and heavy-hitters of their team.
- MODOK also counts as Tony's Evil Counterpart, given his intelligence and often blinding ego. It only gets reinforced when at the end of the season, MODOK becomes the leader of the Cabal.
- Hyperion to Hawkeye - Both being incredibly immature and lacking common sense the majority of the time.
- The Adaptoid to Falcon - Both are the teams' main air support, and Falcon tends to go with the flow, much like the Adaptoid, albeit in a much less literal sense.
- Took a Level in Badass: They went from Skull and MODOK in a Big Bad Duumvirate to a powerhouse of a league of evil.
- With Great Power Comes Great Insanity: Averted during their biggest victory; when they get their hands on the Tesseract, the entire group smartly weighs their options and ultimately come to a practical decision on what to do with it.
Voiced by: Liam O'BrienA brilliant, ruthless and power-hungry Nazi officer and prototype Super Soldier during World War II and the current head of the terrorist group HYDRA. The Red Skull is the Big Bad of the series, leading a Legion of Doom called the Cabal in addition to his own HYDRA forces.
- A God Am I: He's always had this, befitting a supervillain, but takes it Up to Eleven at the end of Exodus, when he's merged with the Tesseract.
- The Bad Guy Wins: He pretty much gets what he wants in the first episode, "Blood Feud", and "Super-Adaptoid".
- And again in "Bring On The Bad Guys".
- Once more in "By the Numbers". Though he loses his stolen Arc Reactor, he does get the Tesseract.
- Bad Boss: In Bring On The Bad Guys, he starts making an effort to not be this, and as a result, the Cabal begins working as a much more cohesive and effective unit.
- Exodus reveals just how bad of a boss Skull is. Skull used the Tesseract to open portals to other worlds for MODOC, Dracula, Attuma and Hyperion to conquer for their own (ones that accommodate the conquering villain, at that), but Tony reveals it's just essentially a window that will kill anyone who walks into it. Yes, that's right. Skull was going to massacre AIM, HYDRA, Dracula's vampires, the Atlanteans, and his team all in one hit.
- Big Bad: Of the first season.
- Heel–Face Turn: Sort of. After apparently stealing the Power Stone from his master, Thanos, he flees to Earth and begs the Avengers for help, and doesn't object to being taken into their custody. Regardless of whose side he's on, he's definitely not the Big Bad anymore. However, since the Time Stone fixed him, he's a threat again, but won't be heard from for a while.
- Chekhov's Gun: His stolen suit of Iron Man armor.
- The Chessmaster: This guy excels at planning.
- Chronic Backstabbing Disorder: First, he forms the Cabal to defeat the Avengers and acquire the Tesseract, then decides to get rid of all his allies with the Tesseract. Then after giving the Tesseract to Thanos, he steals the Infinity stones from him. THAT turned out to be a bad idea.
- Clasp Your Hands If You Deceive: He is often shown doing this while sitting in his command chair aboard his submarine.
- Composite Character: Like his movie counterpart, he's a combination of the Skull and the first Baron Zemo, with the Dark Reign version of Norman Osborn thrown into to the mix.
- Cool Boat: His current base of operations is a rather impressive looking submarine.
- The Dark Heart: Until later episodes, he's the only thing keeping the Cabal together by forging bonds of genuine trust between the villains. This proves so effective that they come to respect his leadership and willingly follow his command. It's fitting that Skull ends up being the one who betrays them and nearly kills them all.
- Disability Superpower: The serum may have made him a Super Soldier but it also was slowly killing him. He tries to steal Cap's body to avoid death and when that doesn't work, he take's Tony's reactor and armor.
- The Dreaded: Iron Man nearly has an Oh Crap! moment in the first episode when Jarvis shows that Red Skull's still alive.
- Drunk on the Dark Side: Is he ever once he merged with the Tesseract.
- Enemy Mine: He and Dracula really don't like each other; HYDRA invaded Dracula's kingdom in World War II, but they have a common enemy in the Avengers.
- Evil Counterpart: Like Captain America, he's a Super Soldier left over from World War II.
- He's also one to Iron Man as the Iron Skull.
- Evil Versus Evil: He and Doom don't get along. Part of it has to do with the fact they're rivals for world domination. Another part might have to with the fact that Red Skull's an ex-Nazi officer and Doom's half-Gypsy.
- Eviler Than Thou: On the receiving end of this trope. Thanos makes him wet himself.
- Facial Horror: His entire head is a deformed, red skull with eyes.
- Gas Mask Mooks: All of his soldiers wear high-tech gas masks.
- Grand Theft Me: He tries to steal Cap's body in the first episode. Came close to succeeding too.
- Grand Theft Prototype: Since the above strategy didn't pan out, though not for a lack of trying, he decides to settle on acquiring Iron Man's armor and arc reactor. This strategy pays big dividends. Also, he later successfully hijacks the Tri-Carrier, with Nick Fury on board no less.
- Genius Bruiser: He's a Super Soldier and a cunning strategist. Then he went and got Powered Armor.
- The Heavy: Much like Loki in the movie, Skull is revealed to be this, despite having been the Big Bad of the first season, having worked to bring the Tesseract to his true master, Thanos.
- High-Class Glass: He wears a monocle in Bring on the Bad Guys.
- Kill 'em All: One major step towards victory was to wipe out every single member of the Cabal, regardless of nationality or organization.
- Know When To Fold Them: He knows when it is time to cut his loses and retreat. For example, the ending of Ambassador when the attempt on Doom's life failed.
- Manipulative Bastard: "Blood Feud" has him manipulating Dracula into attacking the Avengers, knowing that if Dracula won, he would remove the Avengers from his path, and if Dracula lost, he would be forced to join the Cabal.
- The Man Behind the Man: The reason Dracula and Justin Hammer picked a fight with the Avengers? Him. He's on the other end of this with Thanos, his master.
- Nice Job Fixing It, Villain: Him engaging Doctor Doom in The Ambassador made Captain America figure out that Doom had ulterior motives all along.
- Pet the Dog: In an incredibly dark subversion of the trope. The Cabal is practically giddy when Skull assigns them to conquer worlds hand-picked for them - such as an eternally dark, starless world for Dracula, or an oceanic world for Attuma. Then Tony reveals the portals are just death traps waiting for the Cabal to enter and get themselves killed. Needless to say, the Cabal is completely horrified by this new low Skull's descended to.
- Powered Armor: He steals Iron Man's armor at the end of the first episode.
- Putting on the Reich: Most of the time we see him, he's wearing an SS uniform with the Hydra insignia replacing the eagle and swastika when he is not wearing is suit of armor. Considering that he's actually an ex-SS officer, it's not too surprising.
- "The Reason You Suck" Speech: He does this on occasion, especially towards Iron Man.
- Red Right Hand: Yeah, his disfigured face is a pretty good clue that he is not a good guy.
- Sadistic Choice: He chooses to launch two missiles at Los Angeles and Las Vegas rather than risk the Avengers unsettling the unstable Tesseract in further combat.
- Sanity Slippage: After exiting Thanos' service, he is thoroughly traumatized and nuts. The Time Stone eventually fixed him, yet he doesn't know Thanos has been defeated.
- Skull for a Head: Yeah, that Super Soldier serum he took had a little side-effect.
- The Strategist: Let's just say he proved he is this in By the Numbers.
- Stupid Jetpack Hitler: His origin story? Nazi Super Soldier.
- Super Soldier: possesses the same native abilities as Captain America.
- Take Over the World: His ultimate long-term goal and the reason he wants to destroy the Avengers is because they stand in the way of him achieving it.
- Villain Team-Up: After his first dust-up with the Avengers, he decides he needs a team of supervillians to counter them, hence the Cabal.
- Villainous Friendship: In Bring On The Bad Guys he figures out he and his team must trust each other if they are to defeat the Avengers and if nothing else, he earns it when he successfully masterminds Hyperion's escape. After this, the Cabal is pretty loyal to Skull and admit he's not so bad a leader after all.
- Ultimately proven to be a facade; he plotted to completely wipe out his troops while he had the Tesseract for himself.
- Walking Armory: If the massive salvo he fired at Doom in Ambassador is any indication it looks like he and MODOK upped the firepower on his armor a little bit since he acquired it from Stark.
- Wicked Cultured: even in his craziest moments, he's not shy of referencing classical history and mythology.
- With Great Power Comes Great Insanity: His rationality and caution tend to go out the window whenever he comes into the possession of astounding power. The only notable occasion when he didn't fall to this was in By The Numbers when he makes a rational decision on what to do with the Tesseract. However, when he later merges with the Tesseract, he finally has the bite to back up his bark.
- Xanatos Speed Chess: He does this at times. It is especially evident in the first-episode and By The Numbers. MODOK even lampshades it.
Voiced by: Charlie AdlerWeapons designer for HYDRA, their resident Mad Scientist and right hand man to the Skull.
- Adaptational Badass: MODOK's shown to be more powerful than he usually is in other media. He took down Iron Man quickly, took out the Avengers' jet and came within a hair's breadth of having them kill each other.
- Then comes By The Numbers and he kicks Thor's ass.
- Beam Spam: He has particle beam cannons built into his hover-chair.
- Big Bad Ensemble: He's retaken leadership of AIM in season two after the Cabal's dissolution.
- The Brute: When piloting the Adaptoid. The Avengers even call him out on trading brains for brawn.
- Chekhov's Skill: His ability to disassemble Tony's Iron Man armor comes in handy during the finale where he pulls the same trick on the Cosmic Skull's suit.
- Composite Character: He has more in common with the movie version of Arnim Zola than with the comic version of MODOK.
- Since he started using the Super-Adaptoid as his personal avatar the resemblance to Arnim Zola has become even more pronounced.
- Cephalothorax: He's mostly a head with tiny arms and legs.
- Chewing the Scenery: When he enters the fight for Molecule Kid's wand, he starts hamming it up with gusto.
- The Cracker: He hacks Stark's computer systems in Bring on the Bad Guys.
- The Dragon: Serves as this to Red Skull, having the most authority in the Cabal under him, and was his first subordinate. Skull even acknowledges him as his most loyal follower in Exodus.
- Dragon Ascendant: Briefly becomes leader of the Cabal after Skull's defeat, but the organization disbands not long afterward. He becomes an effective threat on his own though, stealing the mind stone and thinking he can do better than Red Skull.
- Disability Superpower: The process that gave him his super-intelligence, technopath powers, and his freakishly huge head left him confined to a high-tech hoverchair.
- Driven by Envy: He wants to outdo Tony Stark and he is pretty resentful of the fact that Red Skull is leading AIM and HYDRA and not him. He is still quite envious of Red Skull in Head to Head.
- Dude, Where's My Respect?: One of MODOK's strongest character traits is that he craves respect and recognition for what he does. He has an almost heartwarming smile when he's praised by Skull during "Bring on the Bad Guys", and is giddy when Skull thanks him for being his most loyal follower. Which legitimately hurts MODOK when Skull is revealed to have planned to execute him and the Cabal, deeming them no longer of use. Determined to get revenge, he almost immediately allies with the Avengers to take down Skull, and honestly thanks them for their help by saving the fight for another day. When he next appears, he's still harping about Skull, proving just how badly Skull wounded him.
- Enemy Mine: Leads the Cabal into battle alongside the Avengers against the Cosmic Skull.
- Energy Absorption: One of his abilities, as Thor found out when he tried to fire some lightning at him in By The Numbers.
- Et Tu, Brute?: He is completely outraged by Skull's betrayal of the Cabal, and by far carries the biggest grudge against him in The Final Showdown.
- Evil Counterpart: To Tony. Especially evident in The Final Showdown when not only is he able to figure out a way to help defeat Skull, he becomes the new leader of the Cabal.
- Evil Cripple: He is confined to what is pretty much a high-tech wheelchair.
- The Friend Nobody Likes: He's the least popular member of the Cabal.
- Hate Plague: He uses nanobots to unleash one on the Avengers.
- Insufferable Genius: MODOK has an ego even bigger than Tony Stark, no mean feat there, and little impulse control. He also bitter about the fact that the Skull is in charge and views MODOK as little more than a technical adviser and supply officer.
- It's Personal: Well into the second season, he's still hurt by Skull's betrayal.
- Kick the Dog: He uses the Adaptoid to knock some fighter planes out of the sky. His next course of action? Take aim at the helpless pilots who ejected themselves in the nick of time.
- Mad Scientist: He's responsible for HYDRA's tech base.
- My Brain Is Big: So big that he can't use his arms and legs.
- No Respect Guy: Save Skull, the Cabal doesn't think much of him.
- Appears to have finally gotten some respect from the others during The Final Showdown, after his quick thinking and intellect helped engineer Cosmic Skull's defeat. The others don't object (at least for now) when he takes leadership of the Cabal.
- Pet the Dog: When the alliance between the Cabal and the Avengers has successfully defeated the Cosmic Skull, MODOK's first act as new leader is to leave well enough alone and fight another day.
- Pragmatic Villainy: When things get bad in The Final Showdown, he's the first to seriously consider allying with the Avengers, even saving them from certain death.
- Technopath: He can control any type of machinery with his mind.
- What the Hell, Hero?: he of all people wonders why the Avengers would go out of their way to protect Doom from the Cabal.
- When He Smiles: Believe it or not, he has an honest, sincere smile that lights up his malformed face when he's being praised by Skull during "Bring On The Bad Guys".
Voiced by: Corey Burton.The King of the Vampire Nation, Dracula is centuries, if not thousands of years old. He fought with Capatain America against HYDRA and the Skull during World War II when they invaded his kingdom. But that alliance was only temporary, now he seeks Cap's blood as he believes it will make him immune to sunlight.
- Chuck Cunningham Syndrome: Hasn't been seen since the season one finale (save for briefly being seen as a holographic target in "Crack in the System").
- Composite Character: He has much more in common with Baron Blood, particularly his World War II background and his connection to Captain America.
- Dark Is Evil
- Deadpan Snarker: Gets in a good one on both MODOK and Attuma at dinnertime.(after witnessing Attuma's lack of table manners)
Dracula: The repugnant one does have a point. They're called "utensils", try one!
- Enemy Mine: With Captain America by the past, and later with Skull. And with the rest of the Cabal, pulls this with the Avengers against Cosmic Skull.
- Evil Cannot Comprehend Good: He's quite confused when Captain America pushes him out of the way of a Cosmic Unibeam, mostly because he's spent a good deal of the season trying to suck his blood and turn him into an inhuman thrall.
- Evil Counterpart: To Thor since he is the supernatural powerhouse of the Cabal. When there is a battle, Thor and Dracula usually face off.
- Evil Sounds Deep: Already in effect thanks to Corey Burton, but he's given a chilling echo that helps the effect out.
- Fangs Are Evil: He is Dracula, after all.
- Hoist by His Own Petard: He thought drinking the Hulk's blood would make him more powerful. However, the Gamma radiation didn't agree with him.
- Insistent Terminology: Prefers to be called King Dracula and not Count Dracula.
- Knight of Cerebus: The other villains want to kill the Avengers and people. Dracula wants to drain their blood and life-force and convert them into his immortal minions. Being the king of vampires, he brings an aura of menace and horror just whenever he even speaks.Cap: Being right all the time really bites.
Dracula: Clever choice of words... meat.
- Only Sane Man: Shares this role with Skull in the Cabal, compared to zealous Blood Knights Attuma and Hyperion, and the egotistical MODOK who gets easily carried away by his ego,
- Public Domain Character: Though not un-familar in Marvel territory.
- Red Eyes, Take Warning
- Spontaneous Weapon Creation: Swords and daggers created from his supernatural fog.
- The Starscream: Stated he only teamed up with Red Skull to take his power for himself, though in later episodes he's accepted Skull's leadership.
- Super Smoke: Has this standard vampiric power, along with other forms of smoke manipulation (like creating a bank of fog or pulling weapons out of the smoke). He usually transforms into green fog himself to escape a blow or just make a villainous exit.
- Villain Teleportation: Perhaps Dracula's most dangerous trait is that he is infamously hard to even hit.
- Weakened by the Light: He can handle regular light just fine. Anything higher than sunlight and ultraviolet he can't handle.
- Wicked Cultured: The man may bite necks to feed himself on occasion, but that doesn't mean he (or anyone in the Cabal for that matter) approves of Attuma's abysmal table manners.
- Worthy Opponent: He seems to have an obsession with kicking Thor's ass. He also has it in for Captain America.
- Your Soul Is Mine: Threatens to eat, destroy, steal, etc., people's souls when they piss him off. He even used this line against Red Skull, who is less than intimidated.
A prototype robot built by Justin Hammer with the ability to mimic just about anything. It now serves as the CABAL under MODOK's supervision.
- All Your Powers Combined: He copies and adapts to his opponets powers. This led him to have all the Avengers powersets.
- The Brute: Of the Cabal, whenever MODOK controls him.
- The Dragon: Used to be this to Justin Hammer.
- Expy: Whenever someone uses its hologram projector to put their face on its torso, the Adaptoid bears a passing resemblance to the robotic bodies of Captain America foe, Arnim Zola.
- Killed Off for Real: Thor beheads it in Exodus and by the look of horror on his face, MODOK has lost his strongest asset. By Avengers Disassembled, a new Adaptoid was created.
- Mega Manning
Voiced by: Dwight SchultzA psychotic Atlantean warlord, determined to bring all of Manhattan under the sea.
- Apparently Human Merfolk: Borderline example, if it wasn't for his skin-color he would look like an ordinary man in a suit of armor.
- Bald of Evil: Turns out that big helmet is covering a bald head.
- Big Bad Ensemble: Is one of the show's recurring Big Bad's after the Cabal's dissolution, though nowhere near as prominent as the Squadron Supreme or Thanos. He's later arrested after his first appearance since the fall of the Cabal.
- Bling of War: He wears what looks like gold plate-mail.
- Blood Knight: He's aggressive, has a short temper and loves a good fight.
- The Brute: Of the Cabal. He's got a bad temper, is strong enough to take on the Hulk, and is extremely arrogant.
- The Caligula: He's unsurprisingly a dictator ruling Atlantis as a tyrant, contending with a rebel cell.
- Defector from Decadence: The Cabal fell apart after the first season, and Attuma is explicitly mentioned to have left the group on his own terms.
- Did You Just Punch Out Cthulhu?: He is genuinely terrified when Tony and Cap destroy Neptune's Trident.
- Dumbass Has a Point: Rightfully berates his teammates for entertaining the idea of killing the Avengers BEFORE taking their revenge on the Cosmic Skull.
- Evil Counterpart: He's the Cabal's answer to the Hulk.
- Four Is Death: He's #4 on SHIELD's Most Wanted List.
- Generic Doomsday Villain: One must wonder what his motives for flooding the planet were. It's shown he's not too intelligent, so he probably had no greater plans than destruction.
- Lightning Bruiser: Even on land, he is an incredibly agile opponent.
- Monochromatic Eyes: His eyes are solid white.
- Off Model: Though they have visible pupils in "Avengers Impossible."
- Omnicidal Maniac: Had Attuma succeeded in defeating the Avengers, he would've likely flooded the planet.
- O.O.C. Is Serious Business: Though it takes some convincing, and as murderous and brutish as he is, he ends up perfectly willing to aid the Avengers to defeat the Cosmic Skull.
- Smug Super: Everyone on the Cabal is this, but he's certainly the loudest in declaring his supposed superiority to everyone.
- Super Strength: He kicked the Hulk's ass once. Not exactly a person to be taken lightly.
- This Looks Like a Job for Aquaman: So long as there's water around, he's practically unbeatable.
- Slasher Smile: Gives one that's ear-to-ear in Exodus upon hearing that Skull has hand-picked an ocean world for him to conquer.
- Worthy Opponent: Considers his rivalry with the Hulk to be "glorious".
Voiced by: Brian BloomAn alien protector from a destroyed planet. Though he arrives on Earth promising peace, it doesn't take long for his true colors (Smugness, violence, superiority) to surface and make him a threat.
- Adaptational Villainy: He gained the villainy of King Hyperion, his Mirror Universe counterpart from Exiles. As such, he's depicted as a sociopathic Well-Intentioned Extremist who is revealed to have destroyed his own planet when they wouldn't submit to his rule.
- Attention Whore: He laps up the attention he gets. Any and all.
- Badass Cape: A nice over-the-shoulder version, a la Shazam. Later steals Thor's, because he thinks it's cool looking. Thor takes it back by force.
- Beware the Superman: As the Avengers and Earth quickly learn.
- Bitch in Sheep's Clothing: Especially when he's playing the part of hero.
- Blood Knight: Is he ever. In The Final Showdown, he's the least willing to ally with the Avengers against the Cosmic Skull.
- Combat Pragmatist: Unable to simply overpower the Hulk, he decides to impair his fighting ability by wounding one of his arms with his heat vision and then punching the injury really, really hard.
- The Dark Chick: Of the Cabal.
- Did You Just Punch Out Cthulhu?: This guy seriously injured the Hulk. Think about that.
- The Dragon: To Nighthawk among the Squadron Supreme.
- Earth-Shattering Kaboom: He blew up his own planet out of spite. As it turns out, Nighthawk forced Doctor Spectrum to do it, but as he shows when he tries to blow up Earth, he's a) willing, b) capable.
- Even Evil Has Standards: Wouldn't sell out the rest of Squadron Supreme when captured, something that legitimately surprises Ironman and Captain America.
- Expy: Of Superman. his voice actor even voiced Superman's Mirror Universe counterpart, Ultraman, before.
- Eye Scream: while charging up his Eye Beams, Captain America shoved his shield against Hyperion's face, causing a point-blank misfire.
- Faux Affably Evil: He's charming right up until someone says no.
- Flying Brick: He is an evil version of Superman, what else did you expect him to be?
- Human Alien: he looks human, but most definitely is not from Earth.
- Knight of Cerebus: Well, he did blow up his home planet when the people didn't submit to his rule and has no problems with attacking children, which is pretty dark, to say the least. He has a grand total of one humorous moment note in the show, otherwise, he's a vicious, spiteful and cruel monster.
- Knight Templar: Thinks he's a hero combating the forces of evil. But if you oppose him or even disagree with his methods, he views you as part of the problem.
- Logical Weakness: As an Expy of Superman, he also draws power from Earth's yellow sun. But a blue sun, on the other hand...
- Might Makes Right: He's stronger than everyone else, and he expects them to line up and obey him.
- Mythology Gag: His antagonism towards Thor and his rescue from SHIELD by the Cabal darkly mirrors his friendship with the God of Thunder and liberation from the clutches of AIM in Jonathan Hickman's Avengers run.
- O.O.C. Is Serious Business: When Hyperion is calling someone a "villain" that villain being Red Skull, who was just revealed to be trying to wipe out his entire army for the hell of it, you know it's gotten bad.
- Never My Fault: Claims his people simply "Didn't deserve" him.
- Pragmatic Villainy: He makes a perfectly logical point when he pressures Skull to kill the Avengers, as they are "beaten, not broken."
- Psychopathic Manchild: He throws tantrums whenever he doesn't get his way, screams for attention, and can be viciously selfish and ungrateful. He craves attention like a child craves sweets, best seen in the alternate reality created by the Squadron Supreme, when he looks perfectly happy being adored by civilians.
- Rage Quit: So the people of his home planet rejected him and rose up against his totalitarian rule. His response? Blow up his homeworld and start looking for a new planet where he could establish himself as the top dog. Turns out later on it was Nighthawk who ordered the destruction of their planet, and forced Billy Roberts to do so.
- Superpower Lottery: Flight, heat vision, nigh invulnerability, super-hearing, etc.... Basically, all of Superman's abilities.
- Super Senses: He has them and Doom uses the fact he has super-hearing against him by cranking his translator's volume up to the maximum and yelling at him, giving him temporary hearing loss.
- Totalitarian Utilitarian: Oh, he wants to eliminate crime and make peoples' lives better. It's just that his idea of saving people sounds a lot like enslaving them.
- Villainous Breakdown: It's short, but he completely loses it when Iron Man reminds him he enslaved and destroyed his own planet.
- Vigilante Man: hyperion is bent on enforcing the law on the villains. However, he fails into being accepted as Judge, Jury, and Executioner
- Villain Team-Up: He gets busted out of prison by the Cabal and joins their ranks in Bring on the Bad Guys. After Skull's betrayal, he decides go back to the Squadron Supreme.
- With Me Or Against Me: There are two options in his mind: Bow before him, and accept his idea of peace. Or resist him, and bring your fate upon yourself.
- Would Hurt a Child: He's got no problem with harming children.
Thanos & The Black Order
- Voiced by: Isaac C. Singleton, Jr.
- Adapted Out: The literal love for Death that serves as his main motivation in the comic isn't present with this version; instead, he appears to be acting only out of megalomania.
- Adaptational Wimp: In the comics, Thanos with the Infinity Gauntlet received the combined attack of Galactus and an army of celetial beings as powerful as him... and completely no sells it. Here, he is severely weakened by the time Arsenal removes his Infinity Gauntlet, plus a mere satellite beam is enough to kill him. Even then, it took the Avengers everything they had to stop him, and he'll still come back from it.
- A God Am I: He's got the Infinity Gauntlet and enough power to level the entire universe. Not even a Physical God like Thor can compete.
- An Offer You Can't Refuse: He offers to spare Earth in exchange for the Power Stone, but the Avengers don't buy it. However...
- Beware the Honest Ones: Tony describes the Big Bad type as untrustworthy and deny his offer. Thing is, Thanos was pretending to be trapped inside Falcon's containment unit, and made little effort to escape until the Avengers refused his deal, when he could've just broken out and attacked them. Seems Thanos was actually being honest, as shocking as it sounds.
- Brought Down to Badass: Without the Infinity Gems, he's got titan strength that even the Hulk can't compete with.
- The Cameo: At the end of the season one finale.
- The Dreaded: He gives his former lackey Red Skull the shits.
- Evil Laugh: Employs it a lot during his first battle with the Avengers.
- Evil Plan: To collect the Infinity Stones and destroy the universe.
- Evil Sounds Deep: Just like his Marvel Cinematic Universe counterpart. Then again, his voice actor also voiced Sagat and Incognito.
- Fatal Flaw: His big, fat, ego, as evidenced by his use of the Infinity Gauntlet to build statues of himself. When Captain America notices this, the Avengers are quick to cash in on this flaw, which is ultimately Thanos' undoing.
- Final Boss: He is the Avengers' final enemy of the two last episodes of the second season.
- Greater Scope Villain: Of the show, given the former Big Bad, Skull, is bowing down to him. Later steps down to become the Big Bad of the second season.
- Kick the Dog: Beats down on The Watcher, who, being the Watcher, only watches things unfold and did no harm against the Mad Titan.
- The Juggernaut: NOTHING short of the Power Stone itself did anything to him.
- Last Episode, New Character: For season one.
- Red Baron: Thanos, the Mad Titan.
- Shout-Out: Pretty much any trope about him is one he has in common with his MCU counterpart.
- Villainous Breakdown: When Arsenal counters the infinity stones and takes the gauntlet from him.

The Squadron Supreme
Turns out Hyperion's not the Sole Survivor of the Squadron Supreme after all.
- Affably Evil: Squadron Supreme as a group are quick to compliment members of the Avengers they view as worthy opponents. Nighthawk respects Falcon for his technological skill while Hyperion seems to have a respect for Hulk's strength and Zarda respects Thor's power and warrior-skill. Hyperion also is notably affable when around his teammates.
- Badass Crew: All five of the main members are strong enough to take down any super on their own, and the entire world together. Note that Nighthawk isn't as powerful as any of his fellow members, but he's smart, so that's high praise indeed. They're basically the villainous counterpart to the Avengers.
- Battle Cry: "Squadron, Strike!"
- Blood Knight: Hyperion also shows shades of this.
- Big Bad Ensemble: They're the most recurring malevolent force alongside Thanos and Ultron for season two.
- Combat Pragmatist: Every single one of them has no qualms about fighting dirty, doing whatever it takes to overwhelm their (usually far underpowered) adversaries. This is best exemplified when they ganged up on Thor because they knew he proved to be too strong for any one of them to handle alone. Even Thor lampshades they show no honor in battle.
- Composite Character: Arguably, the team themselves, as they're basically the Squadron Sinister with a version of Power Princess, as they're supervillains and their speedster is called Speed Demon.
- Evil Counterpart: To the Avengers. Just like them, they are a team of super-beings with various origins who were their planet's mightiest heroes. Unlike them however, they are a bunch of Knight Templar sociopaths who believe peace and order can only be truly established by fear, and are ready to blow up anyone who refuses to bow to them. They even have a Battle Cry mirroring the Avengers'.
- Expy: Of the Justice League.
- Five-Bad Band:
- Hidden Agenda Villain: The Squadron wants to take over the world and destroy the Avengers, but no one knows what they truly want. Even when asked, the Avengers have no luck getting anything out of any member they defeat. It's later revealed they plan to rule Earth, just like they did with their previous planet, and free it of crime, corruption, and war.
- Human Aliens: Well, some of them are. Zarda is from an island on Earth called Utopia.
- Kick the Son of a Bitch: Attuma's Atlanteans learn too late the Squadron took the Earth first.
- Knights of Cerebus: In a recurring theme for the series, episodes involving them are inevitably more serious than normal. They're not entirely devoid of humor, in contrast to Red Skull and Thanos, but they're more serious nevertheless. It's worse when it's shown that they forced an innocent man to join them and destroy their planet.
- No-Holds-Barred Beatdown: All of them collectively give one to Thor after he refuses to admit defeat, despite the severe beating he gets.
- No-Nonsense Nemesis: The Squadron are by far shown to be dangerously competent villains. Case in point, Speed Demon was able to infiltrate Avengers Tower with almost no difficulty, and without anyone noticing.
- One-Man Army: The five main members are all this. When the five are all together, they're almost unstoppable.
- Power of Friendship: A villainous example. The Squadron Supreme's greatest strength compared to every other villain in Avengers Assemble is that they truly care and support each other compared to every other villain group that were formed through manipulation and lies. However, they did force Dr. Spectrum into joining them and destroying their planet. It later turns out they were only united by their desire for power.
- Sugar and Ice Personality: All of them are quite friendly and approachable with the rest of the group; with their enemies they are ruthless opponents.
- Villainous Friendship: Played with. Squadron Supreme's members are quick to insult one another (particularly Nighthawk) but they're a much more cohesive unit than the Cabal ever was and at times they seem to even like one another.
- Averted with the reveal in "Spectrums" where they're allied with the prism. Its host was forced into including being use to destroy their planet.
- Eventually, it turns out they're just as flawed as the Cabal was—they didn't really trust one another, and power was their only guiding motive.
- Worthy Opponent: View the Avengers or at least some members as one based on their dialogue.
Voiced by: Anthony Ruivivar
- Adaptational Villainy: This incarnation displays behaviour that caused the Nighthawk in the comics' Squadron Supreme to leave that team.
- Badass Normal: He beats Iron Man in his armour using nothing but his fists.
- Bad Boss: Regularly criticizes and insults his "team", and wastes no time in leaving them to their deaths when he tries to destroy Earth.
- Big Bad Ensemble: With Thanos and Ultron. He's the leader of the Squadron and seeks the Avengers' destruction and the world's subjugation. However, Ultron gets killed, and he gets imprisoned, leaving Thanos as the sole Big Bad for the remainder of the season.
- Break the Haughty: The episode "Avengers Underground" is one long episode of Nighthawk realizing he isn't as good as a planner as he thought he was.
- Dirty Coward: Nighthawk is high and mighty while in control, but always resorts to cowardly tactics and prefers to let others die for him. When he loses the uppper hand, he chooses to just sacrifice the Earth, abandon his teammates and run, then uncharacteristically asking for help when backed into a corner.
- Earth-Shattering Kaboom: Blew up his home planet when it resisted his tyranny. He tries to do the same to Earth when he is defeated.
- Expy: Of Batman. He's a stoic Badass Normal equipped with nothing more than tech and fighting skills among a team of super-powered people who constantly stays ahead of his opponents through superior planning and preparation. His voice actor even voiced Batman before.
- Friendly Enemy: He acted like this to Falcon in his debut, until Falcon realized Nighthawk was trying to take out the Avengers.
- Hypocrite: During his battle with Iron Man in "Avengers Underground," he claims he doesn't need anyone. But after his escape craft is brought back down to Earth, he starts calling for Hyperion, telling him he needs help.
- Knight Templar: He claims his actions are to better the Earth, but this rings hollow when he regularly threatens highly-populated cities and tried to destroy the planet when beaten.
- The Leader: He's the Leader of the Squadron Supreme, and they usually follow his lead.
- Machiavelli Was Wrong: Nighthawk doesn't believe in trust and compassion for others, adamantly believing fear is the only true option to peace, and will always keep people in line. Thor lampshades this trope to Nighthawk, telling him that when cowered in fear, true heroes will rise against tyrants like him. He ends up being defeated by this trope, because the Avengers had trust and compassion on their side.
- Order Versus Chaos: He's on the side of order, seeing it as the only way to keep peace on a planet, and accomplishing it means subjugating everyone.
- Rage Quit: When humiliated by The Avengers, he orders Hyperion to destroy the planet in a fit of rage.
- We Can Rule Together: Tried to manipulate Falcon into joining the Squadron due to his strategic brilliance.
HyperionSee his entry in "The Cabal"
Voiced by: Phil LaMarr
- Composite Character: This Dr. Spectrum is named after Billy Roberts, but is black like Kenji Obatu.
- Expy: Of Green Lantern. His powers originate from an alien piece of jewelry that uses emotional energy to create solid light constructs. He's even black like John Stewart from the JL cartoon show and voiced by the same actor, Phil LaMarr.
- Good All Along: He was forced to join the Squadron Supreme with the Power Prism. The Avengers separated Billy from the gem and now he's with SHIELD. However, the gem created its own form and took Dr. Spectrum's place.
- Informed Ability: Doctor Spectrum could create light constructs like the Green Lantern. However, we never actually see him use his powers until the episode Spectrums.
- Killed Off for Real: The Power Prism was completely drained of its energies in "Avengers Underground," which may mean we've seen the last of Doctor Spectrum.
- Person of Mass Destruction: The Squadron Supreme are among the most powerful superpowered beings in the world, but most of them are more in 'precise, controlled One-Man Army' territory than this. Dr. Spectrum, on the other hand, has an offensive output that had the power to destroy an entire planet.
- Poor Communication Kills: In Spectrums, the Avengers learn he managed to convince Antman to build a power amplifier for him, and understandably react by tracking him down to destroy it. In truth, the Power Amplifier wasn't meant to increase his power, but the control he had over his Power Prism so he wouldn't turn evil again. Unfortunately, he fails to explain this to the Avengers in time before they destroy the device.
- Puppeteer Parasite: The Power Prism actually is an alien Emotion Eater taking over Billy Roberts.
- Race Lift: The Billy Roberts Dr. Spectrum is white in the comics, but this version is black like the original Kenji Obatu incarnation.
Voiced by: April Stewart
- Affably Evil: Inverted, and notable for its absence. Unlike the other members of her group, Zarda is all business and very cold, for the most part.
- Played straight in Midgard Crisis, until it transpires that she's being Faux Affably Evil to try and turn Thor. That said, she does have a genuine regard for Thor, he being the only one of the Avengers who impresses her.
- Blood Knight: Zarda knowingly fights four Avengers because she knows it will be a "worthy fight".
- Dark Action Girl: One of the most dangerous ladies in the series.
- Drop the Hammer: like Thor's, her sledgehammer is enchanted. Only she can lift it and she uses it to transmute things and create constructs.
- Evil Counterpart: To Thor.
- Expy: Midgard Crisis doesn't even try to hide the fact that Zarda's a dark copy of Wonder Woman, referring to herself as a Princess of an island called 'Utopia' (i.e. 'paradise') and a warrior princess at that. She even has an invisible ship!
- I Fight for the Strongest Side: Her motive for working in the Squadron Supreme.
- Male Gaze: She does have these from time to time whenever the camera is position towards her shapely rear end and legs.
- Ms. Fanservice: Played Straight in "The Dark Avengers" and "Midgard Crisis" whenever there is a close up to her body
- More Deadly Than the Male: Zarda is far more ruthless and vicious in battle than the other male members.
- Noble Demon: Subverted. It's revealed in Midguard Crisis that she swore the same warrior's oath than Thor, and as such does have a sense of honor, leading Thor to believe she can be redeemed. However, her interpretation of honor focuses on respecting strength and glory only, to the detriment of values like duty or loyalty, meaning it only makes her more of a Social Darwinist and Blood Knight. She genuinely believes in her oath, but the way she applies it is too twisted to actually qualify as a redeeming quality.
- The Smurfette Principle: Zarda is the only female member of the Squadron, as well as the only female villain in the entire show (up until Titania, Supergiant and Proxima Midnight show up later on).
- She's Got Legs: Again, played straight in "The Dark Avengers" and ''Midgard Crisis" or whenever she has a close up to her legs.
- Smug Super: She believes her strength makes her better than everyone else, and that protecting weaker beings isn't worth her time.
- Super Strength: she's almost strong enough to match Thor when he's not holding back. However, as he demonstrates when matters get really serious, almost is not enough.
- Weaksauce Weakness: "The Avengers' Last Stand" reveals that her people are susceptible to electricity. Armed with this knowledge, Black Widow manages to stun Zarda with the juice in her gauntlets.
Voiced by: Jason Spisak
- Dirty Coward: is cocky and confident when everything's going his way, but as soon as the Hulk manages to even things up, he runs straight to Hyperion for help. Then again, a pissed off Hulk with super speed is not something you want to stick around for.
- Expy: As with the rest of the Squadron Supreme, Demon is an expy of the Flash, a super-speedster whose also the jokester of the team. As with Nighthawk and Dr. Spectrum in regards to Batman and Green Lantern, Speed Demon's voice actor has voiced the Flash (and Spisak's case, Kid Flash) before.
- Motor Mouth: Speed Demon REALLY panicked when he was chased by a Hulk with super speed.Speed Demon: SAVEMESAVEMESAVEMESAVEMESAVEMESAVEMESAVEMESAVEME!
- Race Lift: In the comics, Speed Demon is white. This version is Ambiguously Brown.
- Super Speed: His main power.

- Affably Evil: Nuke is generally a nice guy to both the Avengers and his partners on Squadron Supreme.
- Devour the Dragon: When the Squadron Supreme starts losing to the Avengers in their last stand, with Hyperion being de-powered by Black Widow, Nighthawk has him drain Nuke's abilities for the power-up required to destroy the planet.
- Smug Super: Aside from possibly Hyperion, he's the most powerful member of the Squadron, and he definitely knows it.
The Masters of Evil/The Thunderbolts
A new supervillain team who was founded during the Time Skip between season 2 and 3. They started as a relatively inefficient and harmless group, with potentially dangerous powers, but not smart or coordinated enough to use them to their full potential, meaning they would usually get easily defeated by the Avengers. Eventually however, Baron Zemo contacted them and became their leader, turning them into a genuine threat.
Tropes applying to the whole team:
- Becoming the Mask: Most of the team became actual heroes with the exception of Baron Zemo.
- Card-Carrying Villain: The Masters of Evil. The Avengers frequently like to point out how ridiculously Obviously Evil this is.
- Harmless Villain: They start out as a rather incompetent team the Avengers are unable to take seriously...
- Not-So-Harmless Villain: ... then Zemo joins them.
- Heel–Face Turn: Ultimately, the team turns against Zemo, and decide to become real heroes after turning themselves in.
Baron Helmut Zemo/Citizen V
Voiced by: David KayeSon of the original Baron Zemo.
- Adaptational Attractiveness: In the comics, he wears a mask because his face was hideously disfigured during a battle with Cap and Falcon. Here, he's perfectly normal looking, and presumably wears the mask in honor of his father.
- Age Lift: In the comics, Zemo is still the son of the original, but because of Comic-Book Time, he was still very young when he was first introduced. Here, he starts out as a frail, withered old man before the Super Soldier Serum makes him young and strong again.
- Arc Villain: of The Masters of Evil/Thunderbolts arc.
- Aristocrats Are Evil: By virtue of being the heir of a Mad Scientist who was affiliated with Nazi.
- Big Bad: Being the team's leader and the one responsible for making them a legitimate threat.
- Bond Villain Stupidity: When the Thunderbolts betray him, he activates a vibranium death trap to deal with them and the Avengers... then leaves to go make a public announcement of their death without actually making sure they really are killed. Unsurprisingly, this ends up biting him in the ass.
- Evil Counterpart: To Captain America, and a more successful version than Red Skull, having used a similar Super Soldier serum on himself His Citizen V persona has an American flag motif just like Cap.
- Legacy Character: Like in the comic, the original Baron Zemo was an enemy of Captain America during World War II, and Helmut merely is his heir.
- Sinister Shades: Wore these in his first appearance. He dropped them when he started wearing his costume.

- Adaptational Heroism: Sort of. While she did defect in the comic, she still was a Token Evil Teammate at best who sided with the good guys for selfish reasons and would still engage in less-than-moral actions. Her Heel–Face Turn in this version appears more genuine.

- The Brute: By virtue of being the one in the team to be more oriented toward brutal force.
- Size Shifting: Has the ability to grow to giant size.
Voiced by: Jennifer Hale
- Green Lantern Ring: As Songbird, her power has been modified by equipment so she can channel her sonic scream into sound-based constructs.
- Make Me Wanna Shout: Her power is a powerful sonic scream.
Voiced by: Mark Hanson
- Composite Character: He follows the same character arc as the Abe Jenkins Beetle, but his armor comes from the unnamed Latverian Beetle.
- Depending on the Writer: He allegedly is the same Beetle that was in Ultimate Spider-Man, down to having the same design. However, USM Beetle was a Professional Killer and a One-Man Army who was considered as a big threat by SHIELD itself, while this one, like the other Masters of Evil, is depicted as a joke until Zemo steps in.
- Evil Counterpart: To Iron Man with both serving as powered armored members of their teams.
- Powered Armor: All his powers are derived from wearing one.
- The Voiceless: Just like in USM, though he does talk once. This changes after he takes on his heroic persona.
Voiced by: Maurice LaMarcheProud, arrogant and the ruler of Latveria; Doom is an intelligent schemer and chief competitor with the Red Skull in the quest for world domination.
- Badass in Distress: During The Ambassador, when he's forced to go without weapons for the duration of the episode when speaking to the United Nations.
- Benevolent Boss: The Avengers in the alternate timeline where he conquered Earth showed practically no qualms about working for him (besides Natasha, who was kinda forced to marry him).
- Big Bad Ensemble: He's the most recurring major villain outside the Cabal and is actively working against Skull.
- Chuck Cunningham Syndrome: Like Dracula, he hasn't been seen since season one.
- Day of the Jackboot: We get a good look at what New York City would be like if Doom had ruled it for a few years in Planet Doom.
- Demoted to Dragon: Doom actively averts this, vehemently refusing to follow Skull's lead.
- In Exodus, we learn that this was a very smart choice indeed.
- Diplomatic Impunity: Doom's a super-villain but he is also the legitimate head of state of a sovereign nation, which grants him some legal protection. The Avengers trying to find a way around this forms a considerable plot point in Ambassador.
- Don't You Dare Pity Me!: His reaction to Tony offering to assist in rebuilding the Destroyer destroyed area of Latveria, is to shock him, refuse, and tell the Avengers to get the hell off his land.
- Egopolis: He renames Earth Planet Von Doom after he conquers it and changes the Statue of Liberty to a statue of himself when he makes New York the capitol of his world empire.
- Emperor Scientist: Granted, he plays around with magic just as much as he plays around with technology.
- Enemy Mine: The Avengers, especially Cap, end up escorting and body-guarding him during his visit to the United Nations. Of course, Doom has ulterior motives.
- Even Evil Has Standards: For all that that he's an evil, power-hungry bastard, Doom is genuinely horrified when he sees the damage that he did to Latveria while wielding The Destroyer. Black Widow even notes this as the first sign that something isn't right with him: As much of a tyrant as he was, Doom never stooped to killing his own people.
- Evil Is Not a Toy: Invoked when he tries to summon and control the Midgard Serpent. Whether he would succeed in controlling him or not is left ambiguous at best. Later, it's shown that he did succeed in controlling the beast. However, he still went overboard with the Destroyer.
- Evil Overlord: He's the dictator and tyrant of Latveria.
- Evil Versus Evil: He's at war with HYDRA, AIM, and the Cabal, though as of The Ambassador he's on the losing side.
- Fatal Flaw: Pride. Doom utterly convinced of his own inherent superiority that it often blinds him to what other people are capable of.
- Fire-Forged Allies: Doom gains a healthy amount of respect for Cap during "The Ambassador" after they help each other as they're attacked by the Cabal.
- Jerkass Has a Point: We learn in Exodus that he was perfectly sane to reject Skull's invitation to the Cabal.
- Large Ham: The voice directors apparently want veteran actor Maurice LaMarche to tone it back sometimes.
- My God, What Have I Done?: When he finally sees the destruction he's causing in the nearby Latverian city with the Destroyer.
- Not-So-Harmless Villain: He's gradually realizing this about the Cabal.
- Out-Gambitted: By Captain America and the Avengers in "The Ambassador".
- Out of Focus: Appeared as the antagonist of four non-consecutive episodes in Season 1, then was completely absent in Season 2.
- Pet the Dog: He genuinely cares about his country even if he's a dictator. He also went out of his way to save Cap, something that shocked the Cabal and the Avengers into silence for a while. Even if he had ulterior motives, he seems to have at least a hint of sincerity when doing this.
- Powered Armor: he's capable of dishing out some serious hurt while in it.
- Post-Modern Magik: He upgrades the Asgardian weapon with his own tech.
- Rogues-Gallery Transplant: while he's taken on most Marvel heroes over the years, he's most famous as a Fantastic Four villain. Here, he has yet to face the Fantastic Four.
- While he hasn't faced the Fantastic Four onscreen, he states they don't exist in the timeline he created in "Planet Doom" when Thor asks about them.
- Take Over the World: Shares this goal with Red Skull, but so far refuses to join up with him.
- Planet Doom shows us an alternate timeline where he did just that.
- Tin Tyrant: he's a dictator and he wears armour.
- Walking Armory: When Tony scanned his armor he reported Doom was carrying enough firepower to vaporize the Eastern Seaboard.
- Wicked Cultured: Carries himself very high on the horse, enjoys chess, and Tony mentions canceling a movie subscription of his.
- Worthy Opponent: Flat-out states he would only have Cap as his bodyguard, no one else.
Ulik the Troll
Voiced by: Kevin Michael Richardson
- Smug Snake: He talks big, but goes down quickly.
- Starter Villain: He merely serves as a prelude to Doom.
The Midgard Serpent
- Eldritch Abomination: An ancient creature that was sealed within the Earth, and prophesised to bring about the death of Thor.
- Make My Monster Grow: It increases in size the longer it remains active.
Voiced by: Troy BakerThor's brother and the God of Mischief and Evil.
- Blade on a Stick: His Weapon of Choice.
- Cain and Abel: The Cain to Thor's Abel.
- Cool Helmet: like his films counterpart.
- Deadpan Snarker: Everything he says just drips with sarcasm from the moment we see him.
- Flanderization: As noted elsewhere in this section, he's pretty much a copy-paste of the MCU Loki, with his villainy played up. Whilst MCU Loki is Ambiguously Evil as of Thor: The Dark World, this Loki is a straight up villain.
- Enemy Mine: Thor brings him in to help defeat the Doctor Doom-controlled Destroyer.
- Physical God: as per usual for Asgardians.
- Shout-Out: Going with the show's heavily movie-inspired approach, this Loki is an almost complete copy of the MCU version. His first appearance is giving the same Kubrick Stare he gave in the movie, and he's in the same pose as well.
- Smug Snake: While he's competent, he still looks down on the Avengers despite past events and is prone making the same mistakes.
- The Trickster: Well duh, he's the trickster god.
Voiced by: Jason SpisakCEO of Hammer Industries, a major weapons manufacturer and a self-declared rival of Tony Stark. Tony, meanwhile, describes him as an obnoxious loser wannabe.
- Big Bad Wannabe: Wanted to join the Cabal. Unfortunately, his attempted audition didn't impress Red Skull. His robot, on the other hand, did. He tries again in Savage and comes close, again, to joining the Cabal before getting overconfident and getting his ass handed to him. It's a good thing he didn't join anyways, because Red Skull would have wiped him out.
- BFG: Uses one against Iron Man in Savage.
- Canon Immigrant: A rather unusual version in that this version of Justin Hammer seems to be based more off the version depicted in Iron Man 2 rather than the Magnificent Bastard he was in the comics.
- Corrupt Corporate Executive: runs a competitor to Stark Industries.
- Drill Tank: Uses a big one in his mining operation in the Savage Land.
- Evil Counterpart: To Tony.
- Evil Genius: Well, designing and building the Super-Adaptoid definitely took some skill and when he controlled it, he almost beat the team (except for Cap).
- Ninja Pirate Zombie Robot: He mounts cybernetic guns on velicoraptors in Savage.
- Not-So-Harmless Villain: He could be seen as this. He did build the Super-Adaptoid after all, and he almost killed the Avengers with it. That's gotta count for something.
- Not Me This Time: Robots from Hammer Industries attacked the Avengers, and Tony later confronted Hammer who was inside a giant suit of armor controlling the robots. Tony thought he fell for a Wounded Gazelle Gambit from Hammer, but it turns out he had no idea what is going on and why his technology went haywire.
- Smug Snake: He's got an ego bigger then Tony's and he does have some skill with designing weapons, but he's far from Tony's league.
- Villain Decay: After Savage, he was reduced to being attacked and messed with by other villains, actually needing the Avengers' help. He manages to turn this around in Thunderbolts, becoming a legitimate threat once more.
- Villains Out Shopping: He starts break-dancing in Savage.
- Wounded Gazelle Gambit: Iron Man thought Hammer pulled this on him when he pleaded him for help inside a big suit armor, only to seemingly sucker-punch him afterwards. However it's subverted, because Hammer wasn't in control of the suit—Ultron hijacked his tech.
Voiced by: Ralph GarmanIntergalactic media mogul and fight promoter. He kidnaps the Hulk to fight in his gladiatorial television show.
- Corrupt Corporate Executive: His employees are scared of him, he kidnaps and imprisons his 'stars', yeah he qualifies.
- Large Ham: Then again, he is a television broadcaster so this might just be his idea of showmanship.
- Rogues-Gallery Transplant: An enemy of the X-Men in the comics.
- Teleporters and Transporters: How his goons kidnap the Hulk and Hawkeye and how he escapes from them at the end of the episode.
- Villain Has a Point: He verbally rips Hawkeye a new one by pointing out that he and the Hulk fight over every stupid little thing, causing massive collateral damage in the process, and that he just put what they do naturally every day on live television but somehow he is considered a bad guy. You can tell by Hawkeye's facial reaction that he realize Mojo does have a valid point.
- Voiced by: John DiMaggio
- The Dreaded: It is Galactus after all.
- Hoist by His Own Petard: Makes Iron Man his Herald, who proceeds to direct Galactus to a planet set to explode soon. The unstable core proves too much energy even for Galactus to handle.
- The Quiet One: Doesn't speak much during his appearance.
The Winter Soldier/Bucky Barnes
Voiced by: Bob BergerFormerly Cap's best friend, who was believed to have been KIA during World War II. He was actually found by Baron Heinrich Zemo and brainwashed by Red Skull, and now seeks vengeance on his tormentor who took his life away from him.
- Artificial Limbs / Red Right Hand: His cybernetic right arm.
- Ax-Crazy: He spends the entire episode he debuts in trying to kill, whether it's Skull's or innocent civilians.
- Brainwashed and Crazy: Though he's fully aware of the brainwashing and actually prefers his current persona and mindset.
- Card-Carrying Villain: A downplayed example; he knows full and well what he was before Skull's brainwashing, but he doesn't care, and outright calls himself a monster to justify his actions.
- Composite Character: He looks like his movie counterpart, but was "killed" and recreated by the Red Skull, just like in The Avengers: Earth's Mightiest Heroes!.
- Evil Counterpart: To Cap, a fact Played for Drama during their interactions.
- Evil Former Friend: To Cap.
- Late-Arrival Spoiler: Ends up not being a spoiler at all; Natasha outright reveals his past as Bucky.
- Loss of Identity: After being turned into the Winter Soldier. However, now that he's learned of his true nature, he fully embraces his new life despite detesting his freedom being taken from him.
- That Man Is Dead: Fully believes Bucky is dead.
- Pet the Dog: Set his blaster to stun before shooting Cap.
- Revenge Myopia: Claims to be out to avenge himself on Skull, but is willing to murder plenty of innocents in the process if he has to.
- The Stoic: Never shows any signs of tiring or being beaten.
- Tragic Villain: Though not quite as tragic as other incarnations, considering he gladly embraces his new life.
Voiced by: Jim Meskimen, Fred Tatasciore (as Nightmare Ultron)A rogue, evil artificial intelligence bent on human extinction. First appearing at the end of Thanos Triumphant when he possesses Arsenal, who now possesses the power of the Infinity Gems, he quickly establishes himself as the Big Bad of the second half of the second season.
- Arc Villain: After Thanos's first defeat. He becomes the main villain of the third season, with the Antagonist Title of Ultron Revolution.
- Assimilation Plot: Ultron's ultimate goal is to copy himself onto human hosts and eventually replace humanity as the planet's sole sentient lifeform.
- Pulls this on the A.I.M. Supreme-Adaptoid, the Scientist Supreme who wore an Adaptoid suit. The Scientist Supreme himself was affected, and as a result Ultron becomes far more talkative and smug, even stating that his endgame would be to make the world "one big Ultron family."
- Asshole Victim: The victims of his technological attacks are Justin Hammer, A.I.M. (and indirectly, MODOK), and the Roxxon Corporation.
- Back from the Dead: Presumed destroyed once and for all at the end of his arc in Season 2 thanks to Arsenal. As of the first episode of the third season, his body survived as did his programming, merging with an A.I.M.-produced Adaptoid which gives him the MCU look. Much like the first time he returned, the Avengers are surprised, to say the least.
- Thanks to Widow being inside A.I.M., she knew full well that they were in possession of Ultron's body, possibly to give the Adaptoids the ability to adapt faster than usual thanks to his experience with the Avengers.
- Batman Gambit: See Manipulative Bastard.
- Big Bad: Serves as this for the second arc of Season 2. He will later be this full stop in Ultron Revolution.
- Breaking Speech: Tries this on Tony. It doesn't work.
- Came Back Strong: After absorbing the A.I.M. Supreme-Adaptoid (as well as the Scientist Supreme himself), Ultron basically walks through the Avengers' attacks, proving this body is stronger than the Arsenal one. Even if he gets destroyed at the end of every episode he appears in, he'll keep coming back.
- Chekhov's Gun: A piece of Ultron's body was among the items A.I.M. salvaged, but the main focus remained on the Scientist Supreme, then it comes to life and takes the Adaptoid's materials from the Scientist Supreme.
- Demonic Possession: Is capable of taking over various bits of technology, most prominently the Hall of Armors and the Super-Adaptoid. Thanks to season 3, we can add the Supreme-Adaptoid (A.I.M.'s Scientist Supreme merged with Adaptoid tech) to that as well.
- The Dreaded: Everyone takes him seriously and Spider-Man has a Bring My Brown Pants response to finding out that he's back.
- Eviler Than Thou: Because of Ultron, the villains who rely on technology, namely Hammer Industries and A.I.M., have been put out of commission due to their tech being hijacked. As a result, M.O.D.O.K. had to use other means of science to crush the heroes.
- He's Back: Pulls this once the Avengers defeat Thanos, despite never having been mentioned before, refurbishing Arsenal's body and taking the team completely off-guard. Does this once more in Season 3, taking on his MCU appearance full-stop and declaring the beginning of his "revolution" after having been thought destroyed once and for all. A little downplayed since the Avengers knew A.I.M. was holding the remnants of his previous body, but they didn't know he was still active.
- Killer Robot: The archetypal example, but he's evolved to beyond a mere robot.
- Knight of Cerebus: Things instantly get darker and more serious when he turns up.
- Manipulative Bastard: Having known the Avengers for a while, he is perfectly capable of playing them like a violin. Within two episodes of his entrance, he's forced Tony to destroy everything he's ever built and turned the Avengers against each other..
- More Than Mind Control: Considering his possession of the power of the Mind Stone, he could be using it to exaggerate certain personality traits in Steve and Tony to drive them apart.
- Mythology Gag: Ultron's appearance after absorbing A.I.M. Adaptoid tech in Season 3 has him adopt his Avengers: Age of Ultron appearance, complete with articulated mouth and optics, and after also absorbing the Scientist supreme himself, the same version's ego.
- His initial appearance resembles his Phalanx fusion form from Annihilation: Conquest.
- One-Man Army: Proves entirely capable of taking on all the Avengers at once without breaking a sweat. He gets even more dangerous once he hijacks the adaptoid.
- Smug Super: Though he is no doubt one of the Avengers' most serious foes, he often boasts about his superiority and has the smarts to back up his claims. This is taken Up to Eleven in season 3, as he is also in possession of the Scientist Supreme's massive ego and intelligence.(after Tony blows out the door to the living room of the overtaken Avengers Tower)Tony: What? Ultron changed the locks.Steve: Reckless, Tony. You just ruined any chance of surprising him.Tony: "Surprising him"? Have you met Ultron?Ultron: Stark is right. (activates tower defenses) I know your every weakness. Humans are so predictable.
- Tempting Fate: Constantly hitting Stark's Berserk Button about insulting his father and/or his host body Arsenal didn't turn out so well for him.
- Oddly enough he's on the other end of this trope in Season 3. After the defeat of Thanos (the second time), A.I.M. had apparently recovered Ultron's damaged body somehow (perhaps from an even older encounter) and stored it for reasons unknown. At the end of the episode, Thor invites any evil to come and take them head-on after they reunite again. Cue Ultron coming out of the ground like a zombie, with his legs and one arm missing (as well as wires dangling from them), and reaching out for the Scientist Supreme, who donned the bodies of ''three Super-Adaptoids'', receiving his MCU design in the process. Needless to say, Thor should be careful about when to boast.
- Xanatos Gambit: He's always at least one step ahead of everyone, comfortably out-playing Tony and Steve at the same time.
- Widow apparently had knowledge that A.I.M. had possession of Ultron's Arsenal form, which was probably at least partly active as the end of the third season premiere showed. It is possible that Ultron intentionally gave advanced programming to the Scientist Supreme for his Adaptoids, which would mean that Ultron practically handed them victory on a silver platter, and would win in any scenario regardless of participation. If the Adaptoids were able to defeat the Avengers, Ultron wins and proves his superiority. If the Adaptoids merged with the Scientist Supreme and defeated the Avengers? Ultron wins. If the Avengers defeated the Scientist Supreme and he still had at least chunks of the Adaptoids on him? Ultron pulls a rising-from-the-grave and absorbs the Supreme Adaptoid into his own physical form, giving him a new body and allowing him to continue his crusade. In other words, Ultron wins.
Voiced by: David ShaughnessyA criminal who deals in vibranium.
- Artificial Limbs: His lower left arm has been replaced by a sonic cannon.
- Doppelgänger Spin: His sonic cannon can create copies of himself made out of sound.
- Make Me Wanna Shout: His main weapon is a sonic cannon.
- Mythology Gag:
- He is modeled after the version seen in Avengers: Age of Ultron (even having his name spelt the same way), with the addition of his sonic cannon.
- His sonic clones are red (as is his giant sound form), in a nod to his comics self's living sound body, which was mostly bright red in color.
- The suit of vibranium armor he later wears takes this Up to Eleven, pretty much looking exactly like a modernized version of his living sound form from the comics.
- Unexplained Recovery: He transforms into a massive creature of living sound energy, and apparently dies when this form is obliterated. He later returns and is inexplicably back to his human form, with no explanation given for how he's still alive. Even Captain America remarks that he should be dead.
- Unwitting Pawn: To Baron Zemo.
Voiced by: Jim CummingsA thief and industrial saboteur, who has had several run-ins with iron Man.
- Adaptation Species Change: He's human in the comics, but here, he has Inhuman ancestry.
- Adaptational Superpower Change: In the comics, his powers come from his suit. Following his recent terrigenesis, he gains the biological ability to phase through things.
- Deadpan Snarker: He could give Tony a run for his money.
- Intangible Man: His main ability. Following the awakening of his Inhuman genes, he make other objects (like the ground beneath Avengers Tower) intangible too.
- Weaksauce Weakness: His phasing ability doesn't protect him from heat, giving Inferno the edge against him in battle.
Kang the Conqueror
Voiced by: Steve BlumThe despotic ruler of Earth in the far future. His attention is drawn to the present after AIM uses a time portal to steal his tech.
- Conqueror from the Future: Pretty much the Trope Namer.
- Expressive Mask: One that perfectly matches the movements of his face.
- Make an Example of Them: Rather than simply destroying the Avengers when they are stuck in his time, he decides to have them on the run for a while, so as to demoralise the rebels.
- Shut Up, Kirk!: His typical reaction to Captain America's Kirk Summations.Captain America: You're just like HYDRA. And they were just like all the tyrants before them. They always fall.Kang: Not the empire of Kang!
- Smug Super: He considers the Avengers "primitives" compared to him.
- Trapped in the Past: Captain America leaves him stranded in the Jurassic era.
Aaron Reece/Molecule Kid
Voiced by: Daryl SabaraSon of the supervillian Molecule Man, Aaron Reece has recently acquired his father's invention: a device that allows the user to manipluate non-organic matter on the molecular level. He doesn't want to follow in his dad's footsteps and for most of his debut episode just wants to be left alone. Tony eventually convinces him to join SHIELD and talks Nick Fury into taking him in.
- Adaptational Wimp: The original Molecule Man, Aaron's father, can manipulate non-organic matter of the molecular level with a wand. The one from the comics does not need any wand: it's his innate power. And his weakness with organic matter was just a self-imposed limitation, that he has already left behind.
- Canon Foreigner: He's exclusively created for the show.
- Cursed with Awesome: The wand only works for him and his dad, and while it's powerful, it's also wrecked his family, sent his dad to prison and put him in AIM, and by extension HYDRA and Red Skull's, crosshairs.
- Cut Lex Luthor a Check: Reece Sr. invented what Tony Stark rightly called "the invention of the century" and the only thing he could think of using it for was to go on a crime spree.
- Reality Warper: He can manipulating matter at its most basic level.
- Story-Breaker Power: How his dad's wand is viewed and treated in universe.
Voiced by: Frank WelkerThe Allfather of the Nine Realms, and the king of Asgard. One of the most powerful beings in the universe, he is also a fair leader to boot. Though he holds no malice towards Midgardians, he believes they are weak and insignificant in the grand scheme of things. He wishes Thor would choose Asgard over Earth.
- A Day in the Limelight: All Father's Day.
- Big Eater: Comes with being an Asgardian.
- Big Good: He may count, being the Allfather and a far more powerful benevolent being than anyone else we've seen thus far.
- The Big Guy: he's easily the same height as the Hulk and, hilariously, pulls him into a one armed hug.
- Blade on a Stick: His spear Gungnir. Further, in this particular incarnation Gungnir is the source of a vast majority of his power. Anyone who holds it and knows how to access its power can be as powerful as Odin.
- Boisterous Bruiser: it is quite obvious where Thor gets it from.
- The Cameo: He shows up in the prologue of Planet Doom, and later has a larger role.
- Defrosting Ice King: No, he's not Laufey, but he's this over the course of Allfather's Day.
- Did You Just Body Check Odin?!?: Everyone is quite understandably horrified when Hulk knocks him through a wall. Thankfully, Odin is merely impressed by Hulk's strength.
- Hold Your Hippogriffs: Amusingly, Odin himself swears by his own beard alongside his son.
- Jerk Ass Gods: Not as bad as some examples, but Odin views humanity as beneath him, does not mind putting innocents in danger to prove a point, abrasive, and is an emotionally-distant, impossible to please father with the time-travelling episode from Hulk And The Agents Of SMASH shows he has always been like this. Despite this, he does care for his children and Asgard and is a bit more reasonable to those who have proved their worth...even if you have to go through several levels of JerkAss.
- Noble Bigot: He holds no real grudge against humanity, but deems them weak and disappointing. Ultimately the team changes his mind in All Father's Day.
- Proud Warrior Race Guy: He starts to think better of the Avengers after Hulk hits him.
- Reasonable Authority Figure: Despite his temper, he is ultimately this, giving the Avengers the chance to prove their worth.
- Worthy Opponent: Immediately recognizes Hulk as one, claiming he hasn't been hit so hard since he fought Surtur.
Voiced by: Tom KennyA bizarre little imp from beyond the stars. Comes to Earth seeking to make a star out of Falcon.
- Adaptational Badass: His comic book self was merely a prodigious Shape Shifter. This version can bend reality at will.
- Beware the Silly Ones: Just in case his goofy personality fools you, he has a S.H.I.E.L.D. threat rating of 10
- Cameo: Briefly seen in Mojo World sitting at a bar, next to Star-Lord, watching Mojo's blood sport.
- Reality Warper: To the point he turns Avenger Mansion into his own personal movie set.
- Troperiffic: Of course, otherwise it wouldn't be the Impossible Man. He somehow merges a fight between heroes and villains with a sitcom, and then recreates the climax of the Avengers film.
- Voiced by: Vanessa Marshall
- Ambiguously Evil: Sure, she opposes the characters, but she never showed any true desire to conquer or enslave humanity like the maniacal Loki. All she wanted was entertainment.
- Adaptational Heroism: While no straightforward hero, she definitely doesn't belong in the "Other Villains" folder on this page.
- Dark Is Not Evil: Again, "evil" is a strong word to describe her, but the dark motif remains.
- Deal with the Devil: Agrees to one with Loki, her being the devil in the scenario. And true enough, she ends up betraying him while sticking to their agreement.
- The Grim Reaper: Being the lord of Valhalla and all.
- Don't Fear the Reaper: It's truly hard to get a fix on her, but she's never shown to be malicious.
- Femme Fatale: She's almost always rather seductive and uses a very husky tone of voice when addressing anyone.
- Hot Witch: She's certainly good-looking (in an Evil Is Sexy sort of way), even if her status as "good" or "evil" is up for debate.
- It Amused Me: Her primary goal? Finding some new entertainment, having bored of watching undead Asgardians fight each other.
- Ms. Fanservice: She's the most gratuitous female character on the show thus far, wearing some rather revealing, form-hugging attire.
- Sadly Mythtaken: She's portrayed as the ruler of Valhalla and not Niflheim as in Norse Mythology. Even the comics didn't make this mistake.
- The Smurfette Principle: She holds the distinction of being the first female "villain" on the show, at least until Zarda, who's definitely not Ambiguously Evil, later showed up.
- Stripperific: Her outfit.
- She's Got Legs: Hela is shown to have a very leggy figure through her form-hugging attire.
- Her athletically shapely legs are made even more attractive through the fact that she was shown to be crossing them rather sexually throughout her debut episode and they are shown to be very detailed through her costume.
- Voiced by: Jim Meskimen
- Adaptational Heroism: While no straightforward villain, Arsenal was most often portrayed as a malfunctioning menace in the comics. And had never been an Avenger in the comics.
- Benevolent A.I.: Helps Tony in his job. At first.
- Broke Your Arm Punching Out Cthulhu: He may have helped defeat Thanos, but ends up being blown to bits.
- Composite Character: Of both his comic counterpart and Ultron. Much like the show's incarnations of the Guardians, Heimdall, Volstagg, Odin, and many others, Ultron more resembles his MCU incarnation, with Jim Meskimen even using the sinister drawl James Spader uses. His design even resembles a fusion of his MCU appearance and his form from Annihilation Conquest.
- Dangerous Forbidden Technique: He may use the energies he acquired from the beyond but ends up blown as a result.
- Early-Bird Cameo: Like the Guardians of the Galaxy, Ant Man, and Doctor Strange below, Ultron makes his debut in this series a while before his starring MCU film was released.
- Evil Sounds Deep: Once Ultron takes over.
- Famous Last Words: "Goodbye Tony, my friend."
- Heroic Sacrifice: In The Ultron Outbreak, Arsenal gets to reawaken one last time. Arsenal willingly decides to fly himself to the sun, as destroying himself would also destroy Ultron and save Tony.
- Hijacked by Ganon: Howard Stark's programming apparently had a hole that allowed Ultron to take over, just as Thanos had been defeated.
- The Juggernaut: What he is now that he's absorbed the power of the Infinity Stones.
- Walking Spoiler: Thanks to the ending of the second season.
- We Can Rebuild Him: What Tony does to him after he got blown to bits.
