===Alien races===
{{Main|List of alien races in Marvel Comics}}
The Marvel Universe also contains hundreds of intelligent alien races. Earth has interacted with many of them because a major "[[Hyperspace (science fiction)|hyperspace]] warp" happens to exist in the [[Solar System]].

The three major space empires are:
* the [[Kree]], who rule the Kree Empire (in the [[Greater Magellanic Cloud]])
* the [[Skrull]]s, who rule the Skrull Empire (in the [[Andromeda Galaxy]])
* the [[Shi'ar]], who rule the Shi'ar Empire.
The three are often in direct or indirect conflict, which occasionally involves Earth humans; in particular, the Kree and Skrulls are ancient enemies, and the [[Kree-Skrull War]] has involved humans on several occasions.

The Skrulls have also been known to be in a long and consistent war against the Majesdanians, who live on a milky planet named Majesdane.<ref name=" Vol2#8">'' Runaways'' (vol. 2) #8</ref> The war between the two had started after two Majesdanians, Frank and Leslie Dean of [[Pride (comics)|the Pride]] had been kicked out for criminal activities; the two traveled to Earth, where Frank and Leslie stopped the war against Earth in exchange for giving the Skrulls the location of Majesdane, which was hidden behind the corona of a [[white dwarf]]. The war had gone on for 16 years minimum; it ended abruptly after the Skrulls shot a barrage of missiles at Majesdane, who retaliated.<ref name="Vol2#8"/>

Another prominent alien race is the [[Watcher (comics)|Watchers]], immortal and wise beings who watch over the Marvel Universe and have taken a sacred vow not to intervene in events, though the Watcher assigned to Earth, [[Uatu]], has violated this oath on several occasions.

The [[Elders of the Universe]] are ancient aliens who have often had a great impact on many worlds for billions of years, acting alone or as a group. A power called the Power Primordial is channeled through them.

Many other races exist and have formed an "Intergalactic Council" to have their say on matters that affect them all, such as interference from Earth humans in their affairs.
