While most of the Avengers are household names, when it comes to Marvel comics vs MCU characters, the movies don't always give minor MCU characters the credit they deserve. With decades of back issues to draw from, even the smallest background characters in S.H.I.E.L.D. or Knowhere can have a rich backstory that the movies just don't have time to flesh out.

Characters like the Warriors Three and Dum Dum Dugan have been around since the 1960s and have appeared in hundreds and hundreds of Marvel comic books over the course of many years, but you wouldn't know it from their roles in the MCU. Others, like Cosmo the Space Dog, are newer but still have more interesting comic book counterparts. So go ahead and scroll on down to see the minor MCU characters who have bigger backstories in the comic books.

    Who Is He In The MCU: Cosmo doesn't have much to do in the MCU outside of being a member of the Collector's vast collection of various oddities. 

    What Does He Do In The Comics: In the pages of Marvel Comics, Cosmo started out as a regular Earth dog, but gained both telepathic and telekinetic powers after he was sent into space by the Soviet Space Program. An ally to both Nova and the Guardians of the Galaxy, Cosmo was instrumental in forming the short-lived spacefaring team of heavy-hitters known as the Annihilators.

    Who Is He In The MCU: Though he is set to reprise his role in the upcoming Disney+ show WandaVision, Randall Park's Jimmy Woo was only a bit player in Ant-Man and the Wasp as the federal agent responsible for (and generally ineffective at) maintaining Scott Lang's probation.

    What Does He Do In The Comics: The Jimmy Woo of Marvel Comics has been around for quite some time, having first been introduced in 1956's Yellow Claw #1. He has worked for many different government agencies in the Marvel Universe including the FBI, State Department, and S.H.I.E.L.D. Nowadays, he is perhaps best known as the leader of the Agents of Atlas

    Who Is He In The MCU: Showcased during the opening action sequence of Captain America: The Winter Soldier, Batroc is a pirate hired by Nick Fury as a cover for Black Widow to steal information about Project Insight. 

    What Does He Do In The Comics: Batroc the Leaper is actually a classic Marvel villain who first appeared in 1966's Tales of Suspense #75. A master martial artist with a surprisingly elaborate set of fighting skills, Batroc has become somewhat of a jokey villain in recent years thanks to his appearances in numerous Gwenpool comics.

    Who Is He In The MCU: Sitwell is up there with Coulson, Fury, and Maria Hill as one of the MCU's major S.H.I.E.L.D. players before Hydra's plot is set into motion in Captain America: The Winter Soldier. He was taken out by the Winter Soldier shortly after revealing Hydra secrets to Cap and his cohorts.

    What Does He Do In The Comics: Would you be surprised to learn that Sitwell was introduced in 1966's Strange Tales #144 and has appeared in over 100 Marvel comics since then? He is one of S.H.I.E.L.D.'s most loyal and dedicated agents, which makes his turn in the MCU all the more surprising to comic fans.
