The Hulk is a fictional superhero appearing in publications by the American publisher Marvel Comics. Created by writer Stan Lee and artist Jack Kirby, the character first appeared in the debut issue of The Incredible Hulk
(May 1962). In his comic book appearances, the character is both the
Hulk, a green-skinned, hulking and muscular humanoid possessing a vast
degree of physical strength, and his alter ego Dr. Robert Bruce Banner, a physically weak, socially withdrawn, and emotionally reserved physicist. The two exist as independent dissociative personalities, and resent each other.

Following his accidental exposure to gamma rays while saving the life of Rick Jones
during the detonation of an experimental bomb, Banner is physically
transformed into the Hulk when subjected to emotional stress, at or
against his will. This transformation often leads to destructive
rampages and to conflicts that complicate Banner's civilian life. The
Hulk's level of strength is normally conveyed as proportionate to his
level of anger. Commonly portrayed as a raging savage, the Hulk has been
represented with other personalities based on Banner's fractured
psyche, from a mindless, destructive force, to a brilliant warrior, or a
genius scientist in his own right. Despite both Hulk and Banner's
desire for solitude, the character has a large supporting cast. This
includes Banner's lover Betty Ross, his best friend Rick Jones, his cousin She-Hulk, and therapist and ally Doc Samson. In addition, the Hulk alter ego has many key supporting characters, like his co-founders of the superhero team the Avengers, his queen Caiera, fellow warriors Korg and Miek, and sons Skaar and Hiro-Kala.
However, his uncontrollable power has brought him into conflict with
his fellow heroes and others. Despite this, he tries his best to do
what's right while battling villains such as the Leader, the Abomination, the Absorbing Man and more.

Lee stated that the Hulk's creation was inspired by a combination of Frankenstein and Dr. Jekyll and Mr. Hyde.[3] Although the Hulk's coloration has varied throughout the character's publication history, the most usual color is green.

One of the most iconic characters in popular culture,[4][5]

clothing and collectable items, inspired real-world structures (such as
