Superhuman qualities are qualities that exceed those found in humans. Superhuman abilities are found in some fictional characters, especially as superheroes in American comic books. Fictional characters have been portrayed as having psychic abilities, flying abilities, impossible strength, or exceptional proficiency beyond human capability.
 "Superhuman" can also mean something that is not human, but considered to be "superior" to humans in some way, e.g. a tiger may be described as having "superhuman strength".
Popeye the Sailor is an American animated series of comedy short films based on the titular comic strip character created by E. C. Segar.
 In 1933, Max and Dave Fleischer's Fleischer Studios adapted Segar's characters into a series of "Popeye the Sailor" theatrical cartoon shorts for Paramount Pictures.
 The plotlines in the animated cartoons tended to be simpler than those presented in the comic strips, and the characters slightly different.
 A villain, usually Bluto, makes a move on Popeye's "sweetie," Olive Oyl.
 The villain clobbers Popeye until he eats spinach, giving him superhuman strength.
 Thus empowered, the sailor makes short work of the villain.

A healing factor is the ability of some characters in fiction to recover from bodily injuries or disease at a superhuman rate.
 Since the introduction of Wolverine by Marvel Comics in 1974 and inspired by the immense popularity of the character, superhuman healing has become a fairly common power featured in comic books, novels, television, film, and other media.
 The overall efficiency of a character's healing factor often fluctuates due to various writers applying a very broad degree of artistic license.
 Weapon X has been established, on multiple accounts for having the fastest healing factor over all mutants, with the exception of external factors.
 As a result, especially concerning characters depicted in comic books, it has become a very common source of debate among fans.
 Over the years, it has also become common for healing factors to have an umbrella effect, serving as a partial source for multiple superhuman abilities; various powers thus demonstrated include superhuman strength, speed, stamina, agility, reflexes, durability and/or senses, to name the most common.
 The source of a character's healing factor, depending upon the medium, usually ranges from natural genetic mutation, accidental exposure to radioactive materials, artificially-induced genetic enhancement, cybernetic augmentation, magic or even a combination of different factors.
 Despite the ability to quickly recover from wounds, characters with a healing factor are still capable of feeling pain.
Obelix (Obélix in French) is a cartoon character and protagonist in the French comic book series Asterix.
 He works as a menhir sculptor and deliveryman, and is Asterix's best friend.
 Obelix is noted for his fatness, the menhirs he carries around on his back and his superhuman strength.
 He fell into a cauldron of the Gauls' magic potion when he was a baby, causing him to be the only Gaul in Asterix's village who is in a permanent state of superhuman strength.
 Because of this already enormous strength, Obelix is not allowed to drink the magic potion ever again, a ban he regards as being tremendously unfair.
 Other characteristics are his simplemindedness, his love and care for his dog Dogmatix, his anger when someone refers to him as being ""fat"", his enthusiasm for hunting and eating wild boars and beating up Romans.
 His catchphrase is: ""Ils sont fous ces romains"", which translates into "These Romans are crazy!"
, although he considers nearly every other nationality to be just as strange.
