The Avengers of the MC2 universe had a very similar history to the mainstream Avengers until, one day, they discovered a portal that led to another universe. This universe was ruled by Dr. Doom and the Thunder Guard, a group of superhumans under his control. Several Avengers fell in battle, including Hank Pym, while the rest returned to their own Earth. Afterward, Iron Man and the Scarlet Witch sealed the portal to Doom's Earth and the Avengers disbanded. Some years later, a new team would form composed of their successors or those that wished to emulate them. The characters appeared in Spider-Girl over the years, but also had two mini-series dedicated to them titled "A-Next." These characters and tropes that apply to them are listed below:
Mainframe is an Iron Man-esque hero who first appears to answer an Avengers' distress signal and, after the crisis is resolved, decides to stay and help form a new team Avengers. Mainframe's backstory was a mystery for the first half of A-Next, but it was eventually revealed that he was a robot built by Tony Stark and based on his brainwave patterns.
- Body Surf: Mainframe does this whenever his body is destroyed by uploading his programming into an identical body housed on a Stark Industries satellite in space. He later loses this ability when he uses the satellite to smash a large volcano.
- Hand Blast: Mainframe can fire repulsor rays from his hands, just like his predecessor.
- Jerk with a Heart of Gold: Mainframe is a bit cold toward his teammates and refuses to tell them about him being a robot, but he is unquestionably heroic and was one of the biggest supporters of the Avengers' reformation.
- Nigh-Invulnerability: Mainframe's body is pretty darn tough, probably as much as Iron Man's armor, but his ability to body surf into new robotic shells makes him pretty much unkillable, though it didn't stop the villain Ion Man from trying.
- Super Strength: Mainframe is pretty strong, as expected of a robot, though there's a lot more muscle on the team than just him.
- The Leader: Takes charge of the Avengers for the most part, though he is later replaced in this role by American Dream.
- The Smart Guy: He's a robot based on Tony Stark's mind, so he also has shades of this.
Stinger (Cassandra Lang)
Cassandra Lang is the daughter of Scott Lang, the second Ant-Man. She grew up around the Avengers and Fantastic Four (later Five) and became a surrogate family member to those teams. Now in her twenties, Stinger is a scientist who works with her father at a private laboratory. Using equipment created by Hank Pym and her father, Cassie has become a superheroine in her own right called Stinger.
- Childhood Friend Romance: With Doom (Kristoff Vernard). The two grew up together and Cassie worries about him twice in the story before the two seem to share a kiss and get together.
- Clothes Make the Superman: Unlike the mainstream Cassie Lang, this version has no powers and relies exclusively on her equipment.
- Daddy's Girl: BIG time. She even calls him "daddy" despite being a twenty year old woman. Despite her adoration for her father, she still wants to live her own life and finds him embarrassing at times.
- Designated Girl Fight: Between her and the Red Queen (Hope Pym). Helps that they were both patterned after the Wasp.
- Flight: Cassie has wings built into her suit that let her fly.
- Hand Blast: She wears wrist devices that let her "sting" opponents with energy.
- Like Brother and Sister: She's this with J2. She supports him whenever he's insecure about his role as a hero and he worries about her when the other members of the team don't.
- Size Shifter: Cassie is able to shrink in size as long as she's wearing her suit.
- The Lancer: Acts as this to both Mainframe and American Dream, the former because he's uptight and secretive and the latter because she is a newbie with less experience than Stinger herself.
- The Smart Guy: Smart girl, but she's a scientist, so you get the idea.
J2 (Zane Yama)
Zane Yama is the son of the Juggernaut (Cain Marko) and a lawyer, Sachi Yama. He discovers that he's inherited some of his father's power after running from a bully and, while he was asked to join the X-People (an mutant group) he chose instead to join the new team of Avengers. Some of the early drama in the book centers around the fact that Zane is just a young boy despite his massive superpowers.
- Bash Brothers: Has this with Thunderstrike and Stinger both.
- Catchphrase: His is usually "COOL!" whenever he's talking about being a superhero.
- Civvie Spandex: Mostly averted. Zane wears what is essentially a silver version of his father's Juggernaut outfit. However, he also wears one of his father's plaid shirts tied around his waist.
- Disappeared Dad: Cain got locked away in another dimension, so it's just Zane and his mom.
- Hulking Out: Zane does this to gain access to his powers, becoming taller and far more muscular. He can only do it for about an hour before reverting back.
- Just a Kid: This trope is in full force, with Thunderstrike even protesting Zane's membership in the Avengers. He later struggles to fight the Hulk, as he's scared that he'll get hurt, but Stinger manages to talk him into coming back to the fight.
- Like Brother and Sister: With Stinger. He worries about her often and likes to have her around, while she acts as his teacher in the way of superheroics and helps him gain confidence in himself.
- Nigh-Invulnerability: Not as much as the original, as the Hulk notes, because he lacks his father's personal force field. Still, he's taken some pretty heavy hits and was never hurt. Thena, the daughter of Thor, actually smashes her hammer to pieces on his head and he mentions that it tickled.
- Super Strength: Not as much as the original Juggernaut, but Zane's got strength to spare. He tends to fight the heavy hitters that his team comes up against such as the Hulk and an evil version of Thor.
- The Big Guy: For the original four and, even though other strong members join later, for the team at large as well.
Thunderstrike (Kevin Masterson)
The son of the original Thundersrike, Eric Masterson, Kevin moves to New York City from the west coast to study art. He kicks off the original A-Next mini series by traveling to Avengers' mansion to receive something his father left him. This thing turns out to be the Thunderstrike mace from which his father derived his powers, but Kevin learns that he can't use it in the same way. He eventually absorbs the mace's power and becomes the new Thunderstrike and member of the Avengers.
- By the Power of Grayskull!: Calls out "Thunderstrike" to access his powers and change into his taller, muscular alter ego.
- Depower: Lost his abilities after Galactus decimated Asgard.
- Disappeared Dad: His dad is dead and has been for years, with Kevin becoming a superhero to try and be like him.
- Heroic Build: Averted as Kevin Masterson, but played straight when he's Thunderstrike. It's pointed out that Kevin's transformed state is the superhero identity he created for himself as a kid.
- Not Quite Flight: Kevin uses his vibratory "thunderclaps" to launch himself through the air, but he can't actually fly.
- Re-Power: Had his powers restored by Thena, who was instructed to do so by Thor.
- Shatterpoint Tap: Does this with his vibratory powers on a few occasions.
- Shockwave Clap: Thunderstrike's primary power. He can fire vibratory blasts of energy from his hands.
- Super Toughness: While not invulnerable, Kevin does have this, since otherwise he'd break his legs every time he landed from one of his super leap/not quite flight jumps.
American Dream (Shannon Carter)
The cousin of Sharon Carter, Shannon Carter was a young woman who grew up hearing stories about Captain America from her cousins Sharon and Peggy Carter. She was injured in a car accident, but managed to regain her physical abilities and become an exceptional athlete through rigorous training. She and four others were trained by a blind Hawkeye (Clint Barton) as the "Dream Team" and join the new Avengers team.
- Affirmative Action Legacy: Is the female successor to Captain America.
- Badass Normal: Like Captain America, she has no superpowers, just her training and wits. For bonus points, Shannon isn't even a super soldier.
- Early-Bird Cameo: Shannon first appears as a tour guide for Avengers Mansion, which has become a museum.
- Headbutting Heroes: Has this going on with Stinger. The two offend each other throughout their working together and just generally annoy one another.
- Important Haircut: Slices off her long blonde hair while giving a speech about what America stands for, with Captain America's shield no less.
- Improbable Aiming Skills: Has "throwing discs" on the gloves her costume that she throws with incredible accuracy and she later gets a version of Captain America's shield that she can throw just as well as he can.
- Made of Indestructium: Her shield, a duplicate of Captain America's, is this.
- The Leader: Is this to the Avengers in the second mini-series, replacing Mainframe.
Freebooter (Brandon Cross)
Brandon Cross is one of the "Dream Team" put together by Clint Barton, who was his personal mentor. An exceptional fighter and hero modeled after both Hawkeye and the Swordsman, he joins the Avengers.
- Badass Normal: Trained by Hawkeye, so this is expected. He fights just as well and as hard as his superpowered teammates.
- Chick Magnet: He talks a lot about getting dates with beautiful women.
- Composite Character: Of Hawkeye and the Swordsman, essentially.
- We Hardly Knew Ye: He gets very little focus or character development.
Bluestreak (Blue Kelso)
Blue Kelso is a mutant speedster and one of the "Dream Team" recruited and trained by Hawkeye. She's boisterous, flirtatious, and in it for the glory. Nevertheless, she proves to be a true hero throughout both mini-series.
- Affirmative Action Legacy: Blue is essentially this for Quicksilver, as her costume is similar to his and she fulfills his role on the Avengers.
- All Amazons Want Hercules: Blue like men, especially the "superpowered hunks" on the Avengers. In the second mini-series, she seems particularly fond of J2.
- First Girl Wins: Subverted. She was on the team and met J2 first, but he appears to be more attracted to Thena.
- Flirtatious Smack on the Ass: Deals these out frequently.
- Super Speed: Her primary power, which she repeatedly uses to get her teammate out of jams.
- You Gotta Have Blue Hair: Her hair is blue with a white streak.
Crimson Curse (Aerika Harkness)
A young witch and the granddaughter of Agatha Harkness. She is recruited and trained by Hawkeye as part of his "Dream Team" before she joins the Avengers. Reserved, especially compared to the bombastic Bluestreak or the flirtatious Freebooter, Aerika is nevertheless one of the most powerful members of the new Avengers team. She is later the first casualty of the team when she gives her life to stop an alternate reality Dr. Doom.
- Blow You Away: Aerika's magic allows her to control the wind and generate powerful gusts against her enemies.
- Green Thumb: Her powers also allow her to grow and manipulate plants.
- Flight: Her control of the wind allows her to fly.
- Heroic Sacrifice: Pulls one of these by using her magic to oppose an alternate version of Dr. Doom. She stops him, but the effort causes her to implode.
- Hot Witch: She's got the body of a superheroine and is dressed in a red leotard.
- Lady of Black Magic: A mature and reserved witch in a red leotard, and one of the most powerful members of her team thanks to her magic.
- Spider-Sense: Aerika's magic give her a sixth sense for when things are going wrong.
Sabreclaw (Hudson Logan)
The son of Wolverine, Sabreclaw first appeared as a member of the Red Queen (Hope Pym's) Revengers team. He later returns in the second mini-series and joins the Avengers, though he doesn't earn their trust until the last issue.
- Absurdly Sharp Claws: Sabreclaw has a natural set that seem to be reinforced by some kind of metal.
- Blood Knight: Evident in his fights against zombies conjured by Sylene. The other Avengers want to run away because the zombies won't die, but Sabreclaw is enjoying himself too much.
- Good Thing You Can Heal: Takes a powerful energy blast right to the face and probably would have died if he hadn't inherited his dad's healing abilities.
- HeelFace Turn: Was a Revenger, but later decided to join the Avengers proper when their membership was low, seemingly just because he wanted to try out being good.
- Super Senses: Just like dear ol' dad.
- Super Strength: A mild case, but still present.
- The Friend Nobody Likes: Well, teammate at least. Since he tried to kill them before and he has a sour personality, he ends up being this to the other Avengers.
Katherine "Kate" Power (Formerly Energizer)
Originally Katie Power aka Energizer of the Power Pack, Kate Power is all grown up and was mostly retired as a hero. She later joins the Avengers after aiding them at the behest of her old friend, Franklin Richards.
- Hand Blast: Essentially what her power boils down to.
- Noodle Incident: Something happened to one of her brothers in the past and it was bad, though it was not stated exactly what it was.
- She Is All Grown Up: Appears to be in her late teens/early twenties. Either way, she's a far cry from the little girl with Pippi Longstocking braids.
The princess of Asgard and the daughter of Thor and an Asgardian woman, Thena travels to Earth to restore Thunderstrike's powers, but gets embroiled in an Avengers related plot and ends up joining them in battle.
- Affirmative Action Legacy: Is this to her father, Thor, as she is essentially a female version of him.
- All Amazons Want Hercules: Gives J2 a kiss after being impressed with his strength and fighting prowess.
- Boisterous Bruiser: Wouldn't be an Asgardian if she wasn't.
- Break the Haughty: Her bragging stops after she breaks her hammer on J2's head and he tells her that it tickled.
- Generation Xerox: She and her cousin Sylene are this for Thor and Loki, respectively.
- Smug Super: ABSOLUTELY. Talks up her power a ton, especially when she first appears.
- Super Strength: Possesses a good bit of this, enough to shatter a large piece of ground by hitting it with her hammer, though she was not nearly as strong as J2 and shattered her hammer when she hit him with it. Also, her second hammer weighs close to a ton but she lifts it with one hand easily.
- Weapon of Choice: Hammers, like her father. The first one she has is magical, but was shattered on J2's head. She later acquired a titanium/steel alloy one as a replacement.
- Weather Manipulation: Can do this with or without her hammer.
The Fantastic Five are the MC2 universe's premier superhero team. Like in the mainstream universe, the Fantastic Five started out as the Fantastic Four but the name was later changed to reflect the growing roster of the team. In their first mini-series, the team's roster consisted of the Human Torch, Ms. Fantastic (Lyja the Skrull), The Thing, Psi-Lord (Franklin Richards), and Big Brain (Reed Richards). By the end of their second mini-series, the team consisted of the above members, but with Grim (Jacob Grimm) taking the place of Big Brain.
Mr. Fantastic/Big Brain (Reed Richards)
The Reed Richard of this universe was very similar to that of the main universe. He accidentally exposed his friends to cosmic rays, transforming them into the Fantastic Four, married Susan Storm, and became the father of Franklin Richards. After an accident in the Negative Zone, Reed decided to remain behind there with Sue, but continued being a hero through the use of a robot called "Big Brain." After the first mini-series, he came back and rejoined the Fantastic Five, but left again at the end of the series due to an incident between him and Doom.
- Absent-Minded Professor: Is called out on this by Sue, and he promises to get better.

- Beauty Is Never Tarnished: Averted. In the original mini-series, Reed had a half melted face and one side of his body sagged drastically.

- Happily Married: To Sue, natch.
- Headbutting Heroes: Him and Johnny over leadership of the team.
- Papa Wolf: Pretty protective of Franklin.

- Rubber Man: Yep, it's kind of his thing.
- The Leader: Of the original incarnation of the Fantastic Four/Five.
- The Smart Guy: Also this. It's Reed frickin Richards after all.
Invisible Woman (Susan Storm-Richards)
Sue was a founding member of the Fantastic Four, elder sister to the Human Torch, wife of Reed Richards, and mother to Franklin Richards. She was the most powerful member of the original team, but is mostly benched during the series for one reason or another.
- Barrier Warrior: This Sue uses her force fields in more aggressive ways than the original, but she still does the whole protective field thing a lot.
- Happily Married: To Reed, of course.
- Invisibility: It's in the name and it was her original power.
- Mama Bear: To Franklin, as per usual.

In the second mini series, she appears more, but ultimately elects not to rejoin the Fantastic Five and instead to help rebuild Latveria and watch over her husband.
- The Heart: Of the original team. She kept the peace between the others.
Human Torch (Jonathan Storm)
Johnny Storm was a founding member of the original Fantastic Four, the younger brother of the Invisible Woman, brother-in-law to Reed Richards, and uncle to Franklin Richards.

The Thing (Benjamin Grimm)
The Thing aka Ben Grimm in this universe is similar to his mainstream counterpart. He went on to marry Sharon Ventura and had twin children with her named Jacob and Alyce. Jacob inherited his rocky appearance and strength, while Alyce gained the ability to emit energy blasts and fly. He is a member of every incarnation of the Fantastic Five, serving as their heavy hitter.

Ms. Fantastic (Lyja Storm)
As in the mainstream universe, Lyja married Johnny Storm though the two stayed together rather than getting an annulment.

Grim (Jacob Grimm)
The son of Ben Grimm and Sharon Ventura, as well as the twin sister of Alyce Grim, Jacob Grim possesses similar powers and a similar appearance to his father. While at first he is merely a hero in training, he later becomes a full fledged member of the Five when Reed and Sue leave the team again.
- Angst? What Angst?: Doesn't seem to sweat not being able to have a normal life due to his appearance. He thinks being a superhero is awesome.
- Nigh-Invulnerability: Was punched through at least four skyscrapers by a cosmically powered Doombot and survived.
- Super Strength: Not as strong as his dad, but he still packs a wallop.
Rad (Alyce Grimm)
The daughter of Ben Grimm and Sharon Ventura, as well as the twin sister of Jacob Grimm. Unlike her brother, Alyce developed the power to transform her body into energy and project it outward. She aids the F5 during the second mini-series and even thinks about joining them, but leaves with her mother at the end of the series instead.
Super-Storm (Torus Storm)
Torus is the son of Lyja and Johnny, and has inherited powers from both of his parents.
