• pantheon: A tribe, clan, or race of gods of a common origin.
• parallel Earth: A counterpart to Earth within another dimension that never diverged from this dimension's Earth, but has somehow come to resemble this Earth in various ways. No known other-dimensional Earth in this multiverse has yet been identified as a parallel Earth rather than a divergent Earth, and no true parallel Earths may exist within this multiverse.
• parallel world: A world which exists in a dimension in a space equivalent to that occupied by a world in another dimension, and whose reality never diverged from that of this other dimension. Just as parallel lines never meet, by definition, neither do parallel worlds. Compare with alternate Earth, alternate world, divergent Earth.
• phase: When used as a verb, a term meaning to pass through another object through altering the synchronization of the atoms of the object passing through with the atoms of the object being passed through.
• pocket-dimension: Also called pocket-universe. A universe whose size is far more limited than that of the Earth dimension.
• polymorph: A being with shape-changing powers.
• precognition: The ability to mentally scan the various alternate futures. Predicting which one of these futures one is likely to experience can never be done with perfect accuracy, since reality must diverge in order for there to be alternate futures, and hence, there will be divergent counterpart of the predictor in each of these alternate futures. A being who possesses precognition is sometimes called a precog.
• prosthesis: An artificial replacement for a missing limb or other body part. If the prosthetic part simulates all of the functions (or more) of the natural part, it is called bionic.
• psi: (Short for psionic or psychic.) The term for any and all extrasensory and extraphysical powers stemming from the mind, specifically astral projection, clairvoyance, levitation, precognition, psycho kinesis, telepathy, and teleportation.
• psion: A theoretical particle of energy produced by the mind that is involved in the psi powers.
• psionic: An adjective referring to psions (see psions), to the powers or energies based on psions (e.g., psionic powers, psionic energy), or to mechanical means to stimulate the natural psi powers. Abbreviated to psi only when describing the powers.
• psychic: An adjective referring to the psi powers.
• psycho kinesis: The psi ability to move or manipulate physical matter without physically touching it. The word is synonymous with telekinesis, which has the added connotation of greater distance being involved between the matter being manipulated and the manipulator.
• Pym particles: A theoretical particle discovered by Dr. Henry Pym that enables size changing and mass shunting.

• radar sense: An extrasensory means of perception by which the brain generates electromagnetic waves which travel outward, bounce off objects, and are again picked up by the brain, which thus determines what its surroundings are.
• robot: A mechanical entity sometimes but not always possessing a humanoid configuration. Compare with android, cyborg, synthezold.

• sentient: As used in this site, a term meaning having intelligence of or beyond or only slightly below the human level.
• sorcerer supreme: A practitioner of the mystic or magic arts who has greater skills than all others or commands a greater portion of the ambient magical energies than any other organism on a given world or dimension. By definition, there can be only one sorcerer supreme per world at a time.
• soul: A living or once-living being's life essence, consciousness, or spirit.
• space warp: A natural or artificially created nexus leading from one point in space through hyperspace into another point in space. See hyperspace, nexus.
• sub-space: Hyperspace. Originally a term mistakenly applied to the Negative Zone. See hyperspace, Negative Zone.
• Subterranean: Any of the various sub-species of humanity who dwell beneath the Earth's surface.
• Succubus: A female demonic creature who feeds upon the life essences of living beings. Also see incubus.
• super hero: A generic term popularized by tablod newspapers such as the Daily Bugle to refer to all costumed crime fighters regardless of whether they possesses superhuman powers or not. The term is used by the general public but is rarely empoyed by the crime fighters themselves except ironically.
• superhuman: A skill, ability, or power that is outside the parameters of achievement by ordinary human beings. It is also a term for any being who possesses such a skill, ability, or power.
• superhumanoid: Referring to a skill, ability, or power that is outside the parameters of achievement by ordinary humanoid beings. It is also a term used for any humanoid being who possessing such a skill, ability, or power.
• super-villain: A generic term popularized by tabloid newspapers such as the Daily Bugle to refer to all costumed criminals regardless of whether they possesses superhuman powers or not. The term is used by the general public but is rarely employed by the criminals or their adversaries except ironically.
• synthezoid: A special type of android empowered by synthesizing energy. The only known synthezoid at present is the Vision.

• telekinesis: The psi ability to move or manipulate physical matter without physically touching it, especially over long distances.
• telepathy: The psi ability to send or receive thoughts directly into or from other minds. A person with this ability is usually called a telepath.
• teleportation: The ability via psionic or artificial means to transport oneself or other people or objects from one point in space to another without having physically traveled the distance between. A person with this ability is usually called a teleporter. See Nightcrawler, Sidewinder, Vanisher.
• Terrigen Mist: A mutagenic or mutation causing substance discovered by the Inhuman scientist Randac. It is potent enough to cause any living organism to mutate from exposure to it, although the Inhumans zealously restrict its use to Inhumans only.
• time line: Also called reality line. The events of a particular reality that define its history.
• time travel: The process of leaving the timestream at a given point, traversing through the timeless realm of Limbo for a timeless interval, and re-entering timestream at another point, not having physically aged in transit. Since there are alternate futures, it is not always possible to travel to the same one. Since traveling into the past always affects reality in at least a minute way, one can never physically travel to one's true past, which is by definition the past in its original state, uncomplicated by extra temporal factors.
• time: The multiverce-wide phenomenon that keeps all reality from happening at once.
• timestream: The multiverse-wide phenomenon that keeps all reality flowing in the same direction, toward entropy. The timestream is not a literal place.
• troll: A certain humanoid being native to Asgard.
