Não, Doc Green se identifica como nem o Hulk nem o Banner, mas como uma entidade completamente diferente:
A personagem Doc Green surgiu após uma tentativa de assassinato em Bruce Banner:
After Banner was repeatedly shot in the back of the skull by a then unknown assassin, his brain was subjected to Arno Stark's Extremis Virus. It was then that a new Hulk persona emerged in the form of Doc Green: The Smartest & Strongest One There is. This particular incarnation of the Hulk neither recognizes himself as either Dr. Bruce Banner or any of the various Hulk personas/incarnations. He has thus made it his mission to eliminate all gamma-based weapons and threats from the planet. This includes the other Hulks: Skaar, Red She-Hulk, Lyra, She-Hulk, A-Bomb and Red Hulk.
