Healing factor

A healing factor is a term used to describe the ability of some characters in fiction to recover from bodily injuries or disease at a superhuman rate. The term itself is most commonly applied to comic book characters in the Marvel Universe, although other quickly-regenerating characters exist.

Artistic license
The efficiency of a character's healing factor, as with all "powers", varies frequently, depending on the situation and the writer writing it, with, as a story is being told, drama being the key factor (one example is Agent Zero, who uses a special acid that temporarily negates the subject's healing factor).

Broad displays of artistic license have often led to debates among fans of particular comic book characters that have superhuman rates of healing, such as Wolverine, Deadpool, Sabretooth, Hulk, et cetera, as to which comic characters heal faster, or what the ultimate extent of their healing factors might be.

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 mediums.The healing factor,although names were used and despite crap written by Wikipedia editors,exited prior to the creation of Wolverine.This ofcourse,is simply poor editing on their part.Characters,like Benson Richards,from short like television series the Immortal,had a kind of healing factor and so did Flint from the Star Trek episode,Reuirum for Mathussalum.These but two examples dated previous to the creation of Wolverine.Captain Scarlet had a kind of rapid healing factor,in series

Characters like Count Dracula and many fictional wizards could rapidly health from injuries.Superman and the Hulk,were but characters,who survive lethal injuries.Creators called it invulnerability,but infact it was a kind of super rapid healing,as was stated later on. The overall efficiency of a character's healing factor often fluctuates due to various writers applying a very broad degree of artistic license. 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's also become common for healing factors to have an umbrella effect in which it serves as a partial source for multiple superhuman abilities; with varying degrees and numbers of powers with superhuman strength, speed, stamina, agility, reflexes, durability and/or senses as 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. ==Comic books== ===Marvel Comics===There are numerous characters within the Marvel Universe that possess some form of accelerated healing ability.
