Savage Banner

After the creation of the Professor Hulk, and believing himself to be Bruce Banner cured, Banner had subconsciously created a safe-guard within the new Professor Hulk persona, while calm the Professor Hulk was stronger than the Savage Hulk, the safe guard wouldn't kick in until the Professor Hulk would get angry; rather than his strength increasing the angier he got instead the Professor Hulk would revert back into the form of Bruce Banner, with the mind of the Savage Hulk rather than that of Banner himself, practically trapping the Savage Hulk in the weak body of Bruce Banner and making him a far less dangerous threat to anyone around him.

This incarnation would cease to be once the Professor Hulk persona would revert back into the Savage Hulk persona.
