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 She In The MCU: Thus far, Monica has only appeared as the child of Carol Danvers's best friend in Captain Marvel, but a grown-up version of the character is slated to appear in the Disney+ WandaVision series.
What Does She Do In The Comics: Interestingly enough, Monica Rambeau was actually the first female Captain Marvel back in the 1980s. Since then, she has become known as Spectrum and she is a powerhouse of a hero. She has been a member of numerous Avengers teams, including the Ultimates, and can turn her body into pure energy.13438Do they deserve a bigger role?

Who Is He In The MCU: Brock Rumlow, AKA Crossbones, was a secret Hydra agent who went up against Cap, the Falcon, and the rest of the squad in Captain America: The Winter Soldier. He made his return in the opening of Captain America: Civil War before sacrificing himself to try to take Cap out.
What Does He Do In The Comics: The Crossbones of Marvel comics is a major villain who has appeared in nearly 200 comic books in the past 30 years and was a key player in the demise of Captain America. While the MCU version is just a normal mercenary, Crossbones is comparable to Steve Rogers when it comes to souped-up physiology in the comics. He was also trained by Taskmaster.13245Do they deserve a bigger role?

Who Is He In The MCU: We got to see a pretty realized version of Zola in Captain America: The First Avenger, Captain America: The Winter Soldier, and Agent Carter. A brilliant scientist who worked not only for the Third Reich and the Red Skull but also for S.H.I.E.L.D., Zola long outlived a normal lifespan by putting his consciousness into a computer.
What Does He Do In The Comics: While he appeared in multiple MCU properties, movie fans have missed out on the purple robotic body that the character is known for in the comics. Seriously, the guy has spent more than 40 years romping around Marvel Comics in a big robot suit that has a giant face in the middle of the torso. It's ridiculous and amazing.12544Do they deserve a bigger role?

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.11241Do they deserve a bigger role?
