1) Squirrel Girl
Debut: Marvel Super-Heroes vol. 2 #8 (1991)
Why she’s interesting: An upbeat problem-solver who wins through optimism, creativity and, yes, squirrels. She’s quietly defeated foes far above her weight class using wit rather than brute force.
Why she’s overlooked: The premise sounds silly at first glance, so casual readers often assume she’s a joke character and miss the clever writing.
Fun fact: Her social media savvy became a running gag long before superheroes having group chats was common.
2) Doop
Debut: X-Force #116 (2001)
Why they’re interesting: A floating green enigma who speaks a private language and archives mutant history from the shadows.
Why they’re overlooked: Surreal humour and cryptic lore make Doop easy to dismiss if you dip in and out of X-books.
Fun fact: Doop’s speech has been translated on a few occasions, revealing surprising depth and dry wit.
3) D-Man (Demolition Man)
Debut: The Thing #28 (1985)
Why he’s interesting: A former wrestler turned street-level hero with a big heart who often protects those society ignores.
Why he’s overlooked: His costume and name invite cheap laughs, which hides the character’s grounded, empathetic stories.
Fun fact: He’s been an ally to Captain America during several crucial arcs.
4) Captain Britain
Debut: Captain Britain Weekly #1 (1976)
Why he’s interesting: The champion of the multiverse-adjacent Otherworld, tied to Arthurian myth and reality-warping magic.
Why he’s overlooked: Many of his key stories launched in UK-only titles or niche imprints, so they slipped past mainstream readers.
Fun fact: The Captain Britain Corps once included countless alternate-universe variants policing the boundaries of reality.
5) 3-D Man
Debut: Marvel Premiere #35 (1977)
Why he’s interesting: A pulp-flavoured hero with enhanced speed and strength created when two brothers merge into one body.
Why he’s overlooked: A Silver and Bronze Age concept that never quite found a modern niche.
Fun fact: Later versions riff on the legacy with nods to retro sci-fi aesthetics.
6) Slapstick
Debut: Slapstick #1 (1992)
Why he’s interesting: A living cartoon who bends physics with mallets, squash-and-stretch elasticity and fourth-wall pranks.
Why he’s overlooked: Toon logic in a superhero universe can be divisive, so he pops up in bursts rather than ongoing runs.
Fun fact: His gags sometimes outwit villains immune to conventional punches.
7) The Orb
Debut: Classic versions in the 1970s; the most famous eyeball-headed take rose to prominence in modern Ghost Rider and event tie-ins.
Why he’s interesting: Cosmic horror flavour mixed with pulpy grindhouse visuals, often tangled in secrets about knowing and seeing.
Why he’s overlooked: Usually treated as a curiosity or villain, his occasional anti-hero turns are easy to miss.
Fun fact: That giant eye has been tied to reality-warping artefacts with unsettling side effects.
8) Elsa Bloodstone
Debut: Bloodstone #1 (2001)
Why she’s interesting: A sardonic monster hunter with superhuman resilience and excellent aim, equally at home in horror and adventure stories.
Why she’s overlooked: She lived on the fringes in mini-series and team books, so casual fans didn’t always catch her best outings.
Fun fact: She often steals scenes with dry British humour and a well-timed stake.
9) Shark-Girl (Iara Dos Santos)
Debut: Wolverine and the X-Men #20 (2012)
Why she’s interesting: A young mutant who shifts into a humanoid shark, bringing oceanic strength and speed to the team dynamic.
Why she’s overlooked: Arriving during a crowded era for mutant introductions meant she competed with many new faces at once.
Fun fact: Her design blends expressive teen heroics with creature-feature flair.
10) Maggott
Debut: Uncanny X-Men #345 (1997)
Why he’s interesting: His digestive system lives outside his body as two sentient slugs that consume matter and convert it into power. Visually odd, conceptually memorable.
Why he’s overlooked: A strange power set that didn’t fit the glossy 90s image of superheroism.
Fun fact: Despite the grotesque concept, he’s often portrayed as compassionate and principled.
