He suppressed that persona (Green Scar/Worldbreaker, what ever you wanna call him) because he was afraid that if he turned back into him he would destroy the world. After Banner got back the ability to transform into the Hulk he knew he was going to turn back into that persona so he trained Skaar to kill him. Skaar didn't stand a chance however but learned that the Green Scar wasn't anywhere close to as big a monster they thought he was. He and Skaar hugged and that has been the Hulks dominant persona ever since. Since he's not as angry as he was during WWH he isn't as strong though.
