Spoilers ahead for After the latest MCU movie retired and killed off some of its most significant superhero characters, more change is definitely coming. And the possibilities are endless, given the rich history of Marvel's comics. Marvel Studios president, Kevin Feige told ComicBook.com that the Avengers: Endgame. MCU continue to expand out into space, despite its earth-bound origins. And obviously, the cosmos are already playing a big part. Beings from other planets are all over this storytelling universe, but it can be easy to get them confused. So we put together this guide to all the alien species in the MCU so far, to help you keep them straight.
When the MCU got its start with
Iron Man in 2008, aliens seemed a long way off. But by the end of Iron Man 2, S.H.I.E.L.D. had found Thor's hammer in New Mexico, signaling that an alien — an Asgardian — had made his way to Earth. And things just sort of took off from there, bringing species after species into this franchise. Some are major characters, others we only see briefly. And you never know which ones the MCU may choose to focus on in the future. (See: that's reportedly in the works.) The Eternals movie
You can at least bet on a
and a third Captain Marvel sequel Guardians movie coming out in the future, so it's a good time to catch up on all of the alien beings you've already met over the 11 years of the MCU's existence. You'll surely have to memorize some more soon. 1 Asgardians
Thor, his father Odin, and his step-mother Frigga are each members of this humanoid race that
hails from Asgard. The Asgardians are known for their superhuman strength and longevity, as well as their connection to Norse mythology. 2 Kree
Krees play a big part in
Captain Marvel, and their longstanding rivalry against the Skrulls resulted in one of the most epic wars in the comics, involving some of the Avengers. They live on the planet Hala, where Captain Marvel first wakes up in the recent MCU film. They're known for their strength and stamina, and Marvel's Wiki reports that Kree women often demonstrate psychic abilities. 3 Sakaarians/Sakaarans
The Sakaarians are heavily featured in
Thor: Ragnarok, which takes place on Sakaar, known as the garbage planet. As Valkyrie says, "Sakaar seemed like the best place to drink and forget and to die one day."
Sakaarians, also known as Sakaarans, are a humanoid race that includes two ethnic groups: "
The red-skinned Sakaaran Imperials and the grey-skinned Shadow People," per the Marvel Wiki. 4 Xandarians Guardians of the Galaxy characters Corpsman Dey (John C. Reilly), Xandarian Nova Prime (Glenn Close) and Denarian Saal (Peter Serafinowicz) are all Xandarians. They look like humans, and in the comics they often battle against the Kree with their army, the Nova Corps. 5 Skrulls
Skrulls show up in
Captain Marvel, shaping the narrative because they're the shape-shifting aliens that can adopt anyone's appearances by changing their DNA. As CBR.com reports, the Skrulls invaded various superheroes in Marvel's comics, and powers including the Fantastic 4. Their leader in the MCU is Talos (Ben Mendelsohn) who ends up working with Carol Danvers (Brie Larson) to defeat the Kree, the Skrull's longstanding rivals. 6 Frost Giants
You've seen Frost Giants in
Thor, The Avengers, and Thor: The Dark World. They're the massive ice-wielding rivals of the Asgardians, led by King Laufey (Colm Feore), who turned out to be Loki's (Tom Hiddleston) father. 7 The Eternals
While most people know that Thanos comes from the planet Titan, little about his species, the Eternals, has been addressed in the Marvel films. The group of Eternals was genetically engineered by the Celestials, for which they became
servants for thousands of years. Last fall, Variety reported that Marvel booked to direct the MCU's upcoming movie about them, so you can expect to see more of Thanos's kind in the future. The Rider director Chloe Zhao 9 Celestials Guardians of the Galaxy 2 villain Ego (Kurt Russell) belongs to the ancient race known as Celestials, which can wield the powers of the Infinity Stones. The powerful beings mimic humans and can manipulate or create beings on a molecular level. 10 Flerkens
You know Flerkens from
Captain Marvel, which introduced one of the cutest characters the MCU has ever seen, the alien-cat named Goose. Goose first belonged to the Kree scientist Mar-Vell (Annette Bening) before Carol Danvers found him while retracing her mentor's steps on earth.
Flerkens have tentacles that can shoot out of their mouths. Their mouths also contain pocket dimensions, so they can hide an object like, for example, the Tesseract. You can definitely expect to see more of these furry creatures in the future, and yes,
they're always cats. 11 Dwarves Of Nidavellir
Peter Dinklage's character in
Infinity War belongs to the ancient race of blacksmiths and foragers known as Dwarves, from the realm of Nidavellir. The Dwarves forged both Thanos' Infinity Gauntlet (under duress) and Thor's weapons, including his hammer, Mjølnir. 12 Flora Colossus
Our favorite tree-like creature belongs to this alien species of plant beings.
The Chitauri have arguably been the most pervasive alien species throughout the MCU's history as they have battled against the Avengers numerous times. Their first appearance is in 2012's
The Avengers, when Loki creates a portal to outer space in New York that allows in the reptilian alien beings. Later, you see a lot of the Chitauri in Infinity War and Endgame as the evil aliens battle as Thanos' army.
Originally from an asteroid field in space called
Sanctuary, or Chitauri Space, the alien beings combine organic genes with machines, making them a technologically advanced and menacing race. 15 Krylorians
This pink-skinned species to which
Guardians' Bereet (Melia Kreiling) belongs hasn't played a major role in the MCU so far, though they often appear in subservient positions. Carina (Ophelia Lovibond) in Guardians of the Galaxy is the Collector's slave. 17 Zen-Whoberians/Zen-Whoberi
The alien race that Gamora belongs to
comes from the planet Zehoberei. As you'll remember from Infinity War, Thanos destroys half of its population and then "adopts" her as a daughter. 18 Halfworlders
Rocket the Raccoon is a both genetically and "cybernetically" engineered animal belonging to the
race known as Halfworlders. Presumably not all of them have the sass that Rocket is best known for. 19 Elders Of The Universe
Benicio Del Toro's
Guardians of the Galaxy character, the Collector, is an Elder of the Universe, which means that he is one of the oldest living beings there is. Another Elder of the Universe is Jeff Goldblum's Thor: Ragnarok character, the Grandmaster, at least according to the comics. Both The Collector and Grandmaster evolved into humanoids after the Big Bang. 20 Watchers
If you thought that the Elders were long in the tooth, the Watchers have them beat, as they are the hands-down
oldest species in the universe. Appearing in Guardians of the Galaxy Vol. 2, this alien race simply observes and compiles information about all beings in the galaxy. You know, no big deal. 21 The Sovereign The Sovereign live on the planet of Sovereign, where the all-gold genetically engineered aliens had captured Nebula in GOTG2. Because the Sovereign fancy themselves pristine and perfect beings, they enlist the Guardians to partake in a messy battle. 22 Abilisk
That battle is against a giant
tentacled alien known as the Abilisk, which can travel between dimensions. Not only is it a giant, durable beast, but it can shoot trans-dimensional rainbow beams out of its mouth, making it spectacularly powerful.
There are way more weird, powerful Marvel aliens where these came from, and some of them will definitely make the jump to the films.
