Aliens from Thor Vol 1 335.jpg

(1.) A being who originates elsewhere than Earth.
(2.) Of or having to do with a place other than Earth.

An alien (or "extraterrestrial") is a being that originates outside of Earth. The universe is teeming with alien life forms, the number of which is incalculable.

Because the denizens of Earth have not yet perfected a practical faster-than-light stardrive enabling interstellar travel, the majority of the alien races encountered by Earth people are those races who have mastered interstellar travel themselves and have visited Earth. Due to the fact that the Earth's solar system is near a natural warp-space access point, there has been a high incidence of alien visitation since before human life first appeared. Indeed, numerous advanced civilizations left outposts on Earth during prehistory, including the Kree, the Lumina, the Arcturans, and the Celestials. In the 20th Century, alien visitation reached epidemic proportions with well over eighty different alien races dispatching exploratory parties and, in some cases, armadas to Earth. The Earth has been of particular interest to the warring Kree and Skrull Empires, since the Earth would be a strategic military outpost from which to launch attacks on the other. One of the main factors accounting for the increase in the extraterrestrial investigation of Earth is the explosive growth of Earth beings who through mutation or transformation have demonstrated superhuman capacities. No other races of beings have manifested such a vast variety of powers as Earth people, and many races are curious to determine why. (The human race's capacity for benevolent mutation is a legacy of the alien Celestials who examined the genetic material of human beings at the dawn of man.) It is these superhuman beings who have been so phenomenally successful thwarting the selfish designs of the scores of alien invaders. Virtually every superhuman champion on Earth has had at least one extraterrestrial encounter.[citation needed]

The majority of the alien races documented here have humanoid configurations (bilaterally symmetrical, upright posture, two arms, two legs, brain located in head). Some are astonishingly similar to the human race, being virtually indistinguishable until the cellular level. Other races resemble humanoid versions of other Earthly animals, such as lizards, skunks, insects, fish, and so on. The reason for this staggering similarity in phenotypes among races evolving on countless worlds separated by millions of light years is not known. A being called "Xorr the God-Jewel" once claimed that the "seeds" of all humanoid faces were contained within Xorri, the now-extinct race that formed the jewel. The validity of this claim is questionable, but it is also unlikely that the vast similarities among certain races can be attributed to parallel evolution. There must something to account for so many coincidences among these alien races, but as yet there is no indication what it is. It is possible that humanoid races do not dominate the universe as it would appear, and that it is mere happenstance that the majority of the alien races Earth has encountered are humanoid.[citation needed]

Alter ego

An alter ego (from Latin, "other I") is another self, a second personality or persona within a person. The term is commonly used in comic books, for the secret identity of a superhero and supervillain.

An alter ego is usually used by superheroes to conceal their identities in order to protect their friends and family from harm at the hands of their enemies, whereas supervillians usually have an alter ego to make sure they don't get arrested.

Alternate Earth

An alternate Earth is a version of the planet Earth which exists within Earthspace in the context of alternate realities. Alternate Earths generally share the same physical characteristics, natural phenomena, and to some extent, life forms and history.

Since most stories in fiction take place on Earth, this planet is arbitrarily regarded as the nucleus of the reality it belongs. Because of this, the term "alternate Earth" is often used interchangeably with "alternate reality."

Alternate Future

Space-Time Continuum from Avengers Vol 4 2 001.jpg

An alternate future is an alternate reality set in a point forward in time compared to the Prime Marvel Universe. In most cases, alternate futures diverged from the Prime Marvel Universe through a specific sequence of events. Some examples of alternate futures include:

Alternate Reality

Multiverse from Infinity Countdown Captain Marvel Vol 1 1 001.jpg

An alternate reality (also known as a parallel reality) is a reality that co-exists separately from another within the Multiverse (a collection of realities). Generally speaking, alternate realities contain variants of the dimensions that make up any given reality. Normally, each reality contains an Earthspace, an Asgard, a Negative Zone, and so on.[1] Because the Earth (and thus the universe it inhabits) is arbitrarily regarded as the nucleus of the reality it belongs to, the term "Earth," "universe" and "dimension" are normally used as synonyms for "reality." The same applies to the terms "alternate Earth," "alternate universe" and "alternate dimension" with regards to alternate realities.

Within the context of Marvel, the term "alternate reality" is used to refer to another fictional reality that isn't the one in which most of Marvel's stories take place, this reality in particular being Earth-616, where the Prime Marvel Universe exists. Realities are formally assigned a numeric designation for better categorization and identification. The Prime Marvel Universe is also known as Earth-616, the Ultimate Universe is Earth-1610, the Marvel Cinematic Universe is Earth-199999, and so on. For a list of realities, click here. While these designations use the prefix "Earth-" instead of "Reality-," it should be noted that "Earth-811" makes reference to the reality itself and not just the planet Earth of this reality.

As mentioned above, alternate realities usually share many elements between each other, but they stand out by how they differentiate from each other. Alternate realities can be different from each other in many ways and to different degrees. If two realities share the same backstory but one of them diverges from the other at a specific event, this reality is better known as a divergent/alternate timeline. For example, in the Prime Marvel Universe, Spider-Man failed to save Gwen Stacy from dying at the hands of the Green Goblin. In the divergent reality of Earth-7736 he succeeded at rescuing her.

In other cases, a reality can share inherent differences from another. The aforementioned Ultimate Universe features many of the same characters from the Prime Marvel Universe, but reinvented and with different backstories. In this reality, Peter Parker was bitten by a genetically-modified spider instead of an spider that was accidentally irradiated, the counterpart to the Prime Marvel Universe's Avengers are a militaristic task-force called the Ultimates, and the Fantastic Four were much younger than their versions from the Prime Marvel Universe, for instance.

Alternate Universe

An alternate universe is the common term to refer to an Earthspace in the context of alternate realities. Generally speaking, alternate universes contain on a macro level the same elements present in other Earth universes (including our own): their own planet Earth, their own Solar System, their own Milky Way, and so on.

It should be noted that all spatially-infinite dimensions are technically speaking an alternate/parallel universe to a given Earthspace. However, the term of "alternate universe" is reserved to the infinity of variants of any given Earthspace that also such.[1]

Man-Thing speaking X'zelzi'ohr


When Man-Thing was granted speech again he spoke the language of X'zelzi'ohr, the universal language. Everyone heard him in a way they were accustomed to, meaning he spoke "American" to the likes of Satana and Moonstone, but was concise and to the point for Ghost, a lewd Englishman to Mr. Hyde, and a total thug to Boomerang.[2]

Negative Zone from Heroes Reborn The Return Vol 1 4 001.png

Matter composed of particles that are the counterparts of the particles composing positive matter (the matter of which this universe is composed), but have opposite charges; e.g., anti-protons instead of protons, and positrons instead of electrons. Should positive matter come in contact with an equal amount of antimatter, both will be annihilated and converted to energy. Ant-Matter makes up most of the Negative Zone.

Artistic License

Artistic license refers to deviation from fact or form for artistic purposes. Writers and artists are allowed to take all sorts of liberties with facts, and are accorded leeway in their interpretation of something, without being held strictly accountable for accuracy. In fiction, writers and artists most often take liberties in the portrayal of physics, biology and chemistry.

In the case of comic books, it's common to apply the concept of artistic license to the deviation from a character's established and habitual levels of power or expertise. For instance, Spider-Man being capable of defeating the cosmically-empowered Firelord in Amazing Spider-Man #270, or Black Panther being able to put the Silver Surfer into an armlock in Fantastic Four #545 are deemed instances of artistic license and are not considered typical of the characters.

Astral Body

The sheath or form that contains a living being's life essence, consciousness, spirit or soul. The astral body is a manifestation of the life essence composed of ectoplasm, an invisible, intangible substance whose source and properties remain unknown. While all living beings have astral bodies, certain adepts using psychic, psionic, or magical means, can separate their astral bodies from their physical bodies without harm. The astral body is also sometimes called astral form, astral self, and spirit form.

The astral form is the non-corporeal manifestation of beings that have the ability of astral projection. The majority of people capable of creating an astral form are psychics, and they usually appear on the Astral Plane. The astral form enables beings to exist within the mind, without a body and transcend through space and time as pure mental energy.
