In the 2014 "AXIS" storyline, when a mistake made by the Scarlet Witch causes various heroes and villains to experience a moral inversion, Bruce Banner attended a meeting between Nick Fury Jr. and Maria Hill of S.H.I.E.L.D. and the Avengers who refused to turn over Red Skull. Later when he sided with Edwin Jarvis and tried to prevent his teammates from executing the Red Skull, the Hulk was thrown aside by Luke Cage. The Hulk's sorrow at his friends' betrayal awakened a new persona known as the bloodthirsty Kluh (described as the Hulk's Hulk, being the ruthless part of himself that even the Hulk repressed) with this new version easily defeating the Avengers, sneering that the Hulk they knew was nothing more than a "sad piece of 'Doc Green's' ID." Kluh then leaves to wreak havoc, with Nova attempting to stop him after witnessing his rampage with the remaining good heroes. As with the other inverted Avengers and X-Men, Kluh was restored to Hulk when Brother Voodoo was summoned back to life by Doctor Doom so that Daniel Drumm's ghost can possess the Scarlet Witch and undo the inversion.
