The Merged Hulk (a.k.a. "Smart-Hulk" or Professor Hulk) possesses Banner's intelligence, the Grey Hulk's cunning, and the Savage Hulk's strength, and his strength level starts at the highest level off all the "Hulk personas." After the "Savage Banner" began to re-emerge, he was forced to restrain his rage to avoid becoming "helpless in mind and body". However, the Professor Hulk isn't able to tap into the famed rage/enhanced strength with the same efficiency as the Savage Hulk.
hahahahaha!
