In the cinematic universe, people often throw around the phrase "gifted." For people born with powers, the word mutant is often used. What I'm asking is, is there a general word or phrase used to refer to any and all people with superhuman abilities?
Edit: I am looking for answers about both the cinematic universe and the comics, to clarify.
The MCU:
This is actually discussed in-universe.
From the Agents of S.H.I.E.L.D. episode One of Us:
Coulson: What do you mean, "other"?
Simmons: [sighs] "Gifted" is both insufficient and too broad. I believe there are two categories we're dealing with. Um, "enhanced" is what I would suggest we call people like David Angar, Mike Peterson ... people whose gifts were man-made.
Enhanced refers to be whose powers were made, such as Captain America and Deathlok. Gifted is used both to refer to people who were born with powers, such as the Inhumans, and as a blanket term for all superpowered individuals.
Given what happened to S.H.I.E.L.D., "enhanced" never gained common-usage.
So no, there is no commonly used term to describe all super-powered individuals beyond "gifted."
The Comics:
In the comics, it's a little less clear. Various terms are used for the sub-groups, including but not limited to "Mutant," "Inhuman," "Super-Soldier," and many others. Due to the sheer number of comics and authors, no catch-all term is used significantly more than others. In the end, "Superhuman" is probably the best term, due to accuracy and how often it's used. It's also the term Marvel's U.S. government used in an important official act.
In Marvel: Agents of SHIELD They refer to people as gifted (born), enhanced (created), and for people who have undergone a change via Terrigenesis are referred to as Inhumans. People from other planets who have powers are simply referred to as aliens.
In Avengers: Age of Ultron Captain America refers to Quicksilver and the Scarlet Witch as enhanced, without knowing the origin of their powers.
In Jessica Jones those with powers are referred to both as gifted and as freaks (by the haters in New York).
These doesn't yet appear to be a consistent term for these types of people.
You have Mutants, who are carriers of the X-gene (Homo Sapien Superior). You also have Eternals, Deviants, Inhumans, Subterraneans, and Homo Mermanus (mer-people). These are the terms for people who are born with powers or the potential to have powers.
Additionally there are people who have been artificially enhanced. These are called Super-Soliders and include Captain Amerca, Luke Cage, Frank Simpson, Peter Parker, and Bruce Banner. That page lists a subcategory for how a Super-Solider was created (Gamma Rays, Weapon X, Oz Formula, Extremis, etc).
