15 Marvel Aliens That Are Way Too Weird For The MCU

Voting Rules
Vote up the Marvel aliens that are cool, but still too strange to work in the MCU.

In many ways, Guardians of the Galaxy has been Marvel’s most surprisingly successful film. While most comic book properties are inherently fantastic and a more than a bit weird, Guardians moved things in a truly bizarre direction. The movie takes place almost entirely in outer space, and the main cast are constantly surrounded by wacky and wild alien races. In fact, four of the film’s protagonists are freaky aliens themselves, ranging from green-skinned humanoid to anthropomorphic trash panda. 

That being said, there are dozens of fictional alien races to play with in the Marvel universe, and some are so weird that they definitely won’t appear in The EternalsGuardians of the Galaxy Vol. 3, or any other corner of the MCU's cosmos. A few of the potential candidates are too visually bizarre to work on the silver screen, while others have traits that could only ever translate as straight-up goofy. The success of Guardians definitely broadened the potential types of stories that Marvel can get away with telling, but they’re not yet ready to explore the deepest and darkest corners of their fictional galaxy.

    Doop has been floating around the X-Men titles for decades now, but fans have yet to fully understand him. Doop is ostensibly an alien, although his exact origins are a bit murky. He’s sort of like Marvel’s equivalent to Slimer from Ghostbusters.

    Doop, however, has a much more defined personality that contains some unexpected quirks. He seems to have a never-ending array of fantastical powers, including the almighty power of seduction. Doop is often seen hooking up with both men and women, and apparently always leaves them satisfied, despite his blobbish appearance.

    Marvel was definitely horsing around when it created the Kymellians, a race of equine-headed but extremely intelligent aliens. Like their Earth-bound look-alikes, Kymellians are very friendly to humans, and have aided several heroic factions in the past, most notably the Power Pack and Fantastic Four.

    Ridiculous facial features aside, the Kymellians are a proud and noble race that always seem to fall on the side of good. That being said, it still had to be slightly embarrassing when Inhuman king Black Bolt had to take one as his bride in a political move.

    Space Phantoms

    The Space Phantoms are one of the first alien races to plague the Marvel universe, as one showed up to torment the Avengers almost immediately after their publication. Space Phantoms are hideous little bug-eyed goblins, but their physical appearance is unimportant given their powers.

    These creepy fellas have the ability to switch places with any individual, sending their victim to an alternate dimension while they gain their appearance and powers. The first Space Phantom used his power to impersonate the Hulk, which led to the jade giant quitting the Avengers when he saw how little they trusted him.

    The character of Bi-Beast is super bizarre no matter how you look at him. Thankfully, he's not a weird comic book send up of bisexuals, but rather an android designed by an alien race. This makes his strange appearance even more inexplicable, because who would intelligently design a creature with two faces, with one on top of the other? Despite his goofy visage(s), Bi-Beast is actually insanely strong, and has gone toe-to-toe with both Thor and The Hulk.

    Mojo is one of those characters that many fans enjoy, but is still super, super gross. He’s an alien from another dimension, one in which he manipulates the lives of heroes and villains for the purposes of creating reality television.

    Mojo is disgustingly obese, has jaundiced skin, and moves around via a set of robotic, insect-like legs, all of which combines for a very visually unappealing appearance. Mojo’s behavior doesn’t make him anymore likeable, and he provides a pretty stark image of what some Marvel creators must have thought about Hollywood producers back in the day.

    The Beyonder is a character with an extremely complicated history. He’s the guy who kidnapped a bunch of Marvel heroes and villains for the original Secret Wars. He then visited Earth for the sequel, Secret Wars II: 2 Secret 2 Wars, during which he adopted a human-like disguise that appeared to be based on Michael Jackson.

    The near-omnipotent Beyond had the power to rewrite reality however he pleased, which made him too powerful to keep around for very long. He faded into the background, but it was recently revealed that he actually belonged to an ancient race of uber-powerful beings, creatively known as the Beyonders.
