Heroes and Allies
Alter Ego: Dennis Dunphy
Notable Aliases: D-Man, Demolition Dunphy, Scourge of the Underworld
First Appearance: The Thing #28 (October, 1985) note ; Captain America #328 (April, 1987) note
A former unlimited-class pro wrestler who befriended The Thing, Demolition Man has had a dubious and difficult career as a costumed adventurer. Although he began as one of Captain Americas closest allies during a difficult time for the patriotic hero, first teaming up with him to investigate the Power Broker, the man who gave him his augmented strength, much of his life following that has proven hard.
- '80s Hair: Sports a truly mean mohawk in his first appearance, but he shaves it to a Bald of Awesome when he joins Cap on the road.
- Alliterative Name: His real name as well as Demolition Dunphy.
- Badass Beard: Recently he has grown a full beard.
- Bear: Dennis was eventually revealed to be gay during Nick Spencer's run.
- Brought to You by the Letter "S": D actually. He deliberately duplicated Daredevil's original costume (though with a knock-off of Wolverine's mask).
- Butt-Monkey: Brian Bendis really doesn't like D-Man, consistently writing him as a crazy, foul-smelling weirdo everyone hates or wants to forget.
- Costume Copycat: Why, yes, his outfit does look like a mix of Wolverine and Daredevil's original yellow costume. Dennis based it on the later, because he's a huge DD fanboy.
- Crazy Homeless People: Ended up as one after he had seemingly met (what was then believed to have been) Bucky's fate at the hands of Flag-Smasher.
- Crime Fighting With Cash: During Steve's time as The Captain, Dennis helps by providing the large amount of cash he got from his wrestling days to cover travel expenses.
- Death Is Cheap: After he became the latest Scourge of the Underworld and fought Cap, Sharon shot him. He eventually came back.
- Drugs Are Bad: They gave him his powers, but messed him up bad.
- History Repeats: Was thought lost after being stuck on a plane that exploded, much like Cap and Bucky's fate toward the end of World War II. In Dunphy's case, though, he was found living among the Inuit, but suffering from Trauma-Induced Amnesia.
- Hollywood Heart Attack: The process that granted Dunphy his superhuman powers has resulted in a dangerous heart condition that has plagued him on several occasions.
- Manly Gay: He's manly and also attracted to men.
- The Pig-Pen: After coming back from his time with the Inuit, he lived among a group of homeless called the Zero People, and hygiene became less of a priority. The rest of the Avengers noticed.
- Psycho Serum: But not by choice after the first time.
- Something Person: The Demolition-Man.
- Super Strength: Dunphy possesses superhuman strength, sufficient enough to enable him to lift up to 15 tons.
- Unskilled, but Strong: D-Man coasted through a lot of fights early in his career. He was a competent enough fighter, and few opponents expected Cap's sidekick to be an order of magnitude stronger than Cap himself. However, the second he ran into someone stronger (specifically, Titania), he was curb-stomped.
- With Great Power Comes Great Insanity: Possibly as a delayed after-effect of the Power Broker treatments, Dunphy became schizophrenic. He believed that a voice was instructing him to collect the Infinity Gems. Instead he stole ordinary gems. Daredevil convinced Dunphy to get treatment for his illness.

Notable Aliases: King Cobra, AZ-1260
First Appearance: Captain America #434 (December, 1994)
A young man from Arizona inspired by Captain America to become a vigilante himself, eventually managing to get superpowers and training from his idol. He was imprisoned in he Negative Zone following the Superhero Registration Act for violating it, becoming crippled in the process. While in prison he ended up leading the prisoners against Blastaar. After teaming up with Star-Lord, he wound up with a really weird bunch of cosmic heroes. And for the record, he hates "cosmic stuff".
- Ascended Extra: Appeared far more often in the second volume of Guardians of the Galaxy than he ever did in Captain America.
- Ascended Fanboy: Of Captain America. This is also part of what gets him into trouble during his appearance in Thunderbolts, since he refused to sign up for the SRA on the grounds that Captain America would, meaning he got into some serious trouble for not being registered.
- Back for the Dead: In Captain America: Steve Rogers #1, he was thrown off a plane by Steve because he found out he was Hydra. He eventually died of his injuries in the hospital before he could tell anyone.
- Badass Normal: What he started out as.
- Chronic Hero Syndrome: Knew what violating the Registration Act would bring on him, and didn't care, because someone needed help.
- Empowered Badass Normal: After accidentally ingesting some of Mr. Hyde's formula, he became super-humanly strong, fast and durable.
- Fish out of Water: Jack's a street-level hero, used to dealing with people like Captain America, and he has a bit of trouble coming to terms with someone like Iron Man. He's way out of his depth with the Guardians. The only reason he doesn't go home is because (as far as he knows) he's still a wanted man.
- Grumpy Bear: He hates cosmic stuff.
- Handicapped Badass: Even whilst in wheelchair, Jack became the de-facto leader of the inmates of Prison 42 after the wardens abandoned the prison during the Secret Invasion and fought off Blastaar's forces in his attempt to gain access to the prison's portal to Earth.
- No Good Deed Goes Unpunished: Saves a girl from some thugs, gets beaten up, crippled, beaten up some more and then thrown into another universe and left to rot for his troubles.
- Only Sane Man: Prior to joining the Guardians, Jack was imprisoned in Prison 42 located in the Negative Zone, for breaching the Superhuman Registration Act. When he joined up with the Guardians, he reacted to most of the cosmic stuff with "I hate cosmic stuff" due to his background as a street faring vigilante.

- Running Gag: He doesn't like 'cosmic stuff'. Not even after it gives him his legs back.

Notable Aliases: "Injun Joe" (by Nomad)

- HeelFace Turn: The Earth spirit first sent Black Crow to challenge Captain America to a trial by combat because, as a symbol of modern America, his death would appease the spirit.

- Magical Native American: He's a Native American empowered by the spirit of the Earth.
Dr. Abraham Erskine
Alter Ego: Dr. Abraham Erskine
Notable Aliases: Dr. Joseph Reinstein
First Appearance: Captain America Comics #1 (December, 1940)
The creator of the Super Soldier Serum that created Captain America. He was assassinated before writing down the formula, which led to several parties attempting to recreate the formula from scratch with little success.
- Death by Origin Story: His death is what made Steve Rogers the only Super Soldier, with most people trying to replicate his formula, with varying successes.
- Expansion Pack Past: Not much, but Avengers: The Initiative reveals he has a son, who's been living a life of quiet obscurity in America all these decades.
- Forced into Evil: Before coming to America, he had to work for the German government, which for a genuinely nice man like Erskine was horrible. Problem is, Nazis don't like hearing the word "no". Fortunately, Nick Fury and his buddy Red Sawyer manage to extract him.
- No Plans, No Prototype, No Backup: The reason Captain America is one of a kind in the Marvel Universe is because he, the only person who knew the formula for the Super Soldier Serum, got shot right after administering it to Cap. Furthermore, for security reasons, he kept no notes of the full treatment, relying on his memory. Attempts at reproducing it haven't gone so well.
Alter Ego: Margaret Alexandra "Peggy" Carter
Notable Aliases: Agent 13, Doc, Hera-2, Mademoiselle, Midge, Peggy-Poo, The Dryad
First Appearance: Tales of Suspense #75 (March, 1966) note ; Tales of Suspense #77 (May, 1966) note ; Captain America #162 (June, 1973) note ; Captain America Vol 9 #9 (April, 2019) note
Margaret "Peggy" Carter is a Marvel Comics character who originally appeared as a supporting character in the comic books featuring Captain America. She was created by Stan Lee and Jack Kirby and introduced in the Marvel Universe in Tales of Suspense #77 in 1966.
She first appeared, unnamed, as a wartime love interest of Steve Rogers in Tales of Suspense #75 (single panel) and #77 (May 1966). She appeared again as the older sister of Sharon Carter in Captain America #161 (May 1973). She was later retconned as Sharon's aunt.
When Peggy was only a teenager, she joined the French Resistance during World War II. She proved to be a valiant and highly capable agent with the Resistance and served on several Resistance operations alongside the hero Captain America. Carter and Captain America fell in love with each other.
When she heard the rumor that Captain America had apparently been killed just before the end of the war in Europe, Peggy withdrew from the world, refusing to speak, dressing in mourning garb, and requiring hospitalization. She began treatments from the criminal Doctor Faustus. After Captain America resurfaced many years after the war, he learned of Peggy's whereabouts when he freed her and others from Faustus' clutches. Peggy eventually regained her mental bearings, and initially kept her love for Captain America to herself. Eventually any romantic feelings between the two subsided, but she formed a new romance with Gabe Jones of the Howling Commandos, one of the first interracial relationships in the comics. Peggy worked for S.H.I.E.L.D. and the Avengers Support Staff until she retired, passing away sometime in 2011.
After so many years only appearing as a Satellite Love Interest for the Sentinel of Liberty, Peggy finally became a central character in the new series Operation S.I.N. (a tie-in to Original Sin, apparently). In this series, she also co-stars with Howard Stark (father of Tony Stark). It was first released in January 2015, mirroring the debut of the Agent Carter television series, which also features Peggy and Howard as major characters in the Marvel Cinematic Universe. The event in Operation S.I.N. is set during The '50s.
Nearly a decade after her death, Peggy made a surprise return in Ta-Nehisi Coates' Captain America, apparently with her youth restored (and a new nose ring). Under the assumed alias Dryad, she lead Sharon and a team of fellow female superheroes, named the Daughters of Liberty, in an effort to rescue Steve from an unjust imprisonment.
An alternate universe version of herself as Captain America also appeared in the 2018 run of Exiles, from a past where Steve Rogers was assassinated and Peggy took up the mantle as the good Captain, joined by Gender Flipped sidekick Becky Barnes.
- Action Girl: Peggy was dedicated to ending Nazi oppression and joined the French Resistance while she was still a teenager.
- Action Heroine: Throwing punches and shooting guns are her preferred ways of beating her enemies.
- Adaptation Dye-Job: Blonde in the comics, brunette in the Marvel Cinematic Universe.
- Adaptational Nationality: She was American in the comics, but is British in the Marvel Cinematic Universe. This is much likely because her actress, Hayley Atwell, is a British-American.
- Amnesiac Lover: Peggy was captured by the Gestapo and was being held captive in Paris when it was liberated by the Allies. However, a shell exploded near her during the battle that freed the city, and the shock gave her amnesia. She was found and identified by Resistance colleagues and sent home to her parents in Virginia. When she began to recover from her amnesia, she was suffering from mental and emotional distress, and kept calling for Captain America.
- Ascended Extra: In the comics, Peggy is, at best, an important footnote to Steve and his primary love interest, Sharon Carter. In the Marvel Cinematic Universe, though, she's become one of the most prominent supporting characters, even after First Avenger seemingly concluded any more adventures in the 40s. The first issue of the 2011 Captain America series even uses her death from old age as a jumping-off point specifically because she'd now be familiar to audiences.
- Back from the Dead: In Ta-Nehisi Coates' run of Captain America.
- Badass Normal: Unlike the captain, she's a normal human without superpowers.
- Battle Couple: With Captain America◊, during the war◊.
- Breakout Character: When Peggy Carter debuted in the comics, it was to be a Temporary Love Interest to Captain America during his time in World War II, but she debuted in The '60s, long after Cap's regular WWII war stories were over. At first she appeared only in Flashbacks (in her first story she wasn't even named!). Under these circumstances, she's rarely been anything more than a Satellite Love Interest in the comics. But when Captain America: The First Avenger came out, since 99% of the film takes place during the War, she naturally had a much bigger role. She took center stage in the one-shot Agent Carter, which was such a huge hit that it spun off into her own regular TV series. It's worth noting that the filmmakers have tried to use Peggy in every single (Earth-bound) MCU vehicle after The First Avenger. Joss Whedon wrote a scene for her in The Avengers, and she has cameos in The Winter Soldier, Agents of S.H.I.E.L.D., Age of Ultron, and Ant-Man.
- Character Death: In the modern-day of mainstream comics universe, she has passed away. Her death is shown in Captain America vol. 6 #1, which is released in July 2011, around the same time of Captain America: The First Avenger's release. ... and then undone after the release of Avengers: Endgame.
- Comic-Book Time: An aversion since, like Captain America, her backstory is tied into the Second World War. This makes her one of few characters of note to die of old age in mainstream comics. For a while, at any rate.
- Composite Character: In the Marvel Cinematic Universe, particularly Captain America: The First Avenger, she combines elements of Peggy Carter (Action Girl-ness and the name and relationship to Sharon Carter) with Lt. Cynthia Glass from the Sentinel of Liberty Miniseries (who had the same look and was also Phillips' aide).
- Cool Aunt: For Sharon. Peggy is the one who inspires Sharon to become an Action Girl and secret agent in her own rights.
- Expy: In her original appearances, she was one for Golden Age Captain America's Love Interest, Betsy Ross.
- First Love: To Steve Rogers in the MCU. In the mainstream comics, his first love was Lt. Cynthia Glass, the Project Rebirth aid.
- Generation Xerox: Peggy Carter was a heroine of World War II and in a romance with Captain America. Her niece Sharon grew up to become a hero in her own right and got involved in a romance with the same long-lived hero.
- Guys Smash, Girls Shoot: Steve prefers to use only his shield when in combat while Peggy is quite the crack shot.
- Heartbroken Badass: When she heard the rumor that Captain America had apparently been killed just before the end of the war in Europe, Peggy withdrew from the world, refusing to speak, dressing in mourning, and requiring hospitalization.
- Jumped at the Call: See the quote above. She dedicated to end Nazi oppression and joined French Resistance.
- La Résistance: She was member of French Resistance during the war against Nazi.
- Lady of War: A competent Action Girl who also manages to be composed, even in battle.
- Legacy Character: Peggy Carter was first known as Agent 13, before her niece, Sharon Carter.
- Nice Hat: An army beret during the war. Agent Carter had a red fedora as her emblem.
- Only Known by Their Nickname: When informally addressed, people refer to her as Peggy instead of Margaret.
- Peggy Carter Is About to Shoot You: In the cover◊ for first issue of Operation S.I.N..
- Related in the Adaptation: Heroes Reborn depicts her and Bucky Barnes as having gotten married after Steve fell into the ice as they're implied to be Rikki's parental grandparents.
- Ret Cannon: After becoming a breakout character thanks to the movies, some details of her MCU self, such as having adventures with Howard Stark, or being brunette, have filtered through into her comic counterpart.
- Retcon: She was once introduced as much older sister of Sharon, later retconned into becoming her aunt.
- Retired Badass: By the modern day, thanks to old age. She served as one of the Avengers Mansion support staff.
- Strong Family Resemblance: As a young girl, she looks a lot like her modern-day niece, Sharon.
- You Are Number 6: "Agent 13" was previously her codename before it's used by her niece.
