Grey Hulk

Grey Hulk is a personality of the Hulk. Unlike the green hulk this Hulk speaks in proper english and is often sarcastic. This Hulk has control over himself, he is very powerful but not as powerful as Green Hulk.

Bruce Banner's body was separated from The Hulk after an experiment called the nutrient bath. But after the experiment Bruce's body suffered some trauma and that was because he couldn't live without the Hulk. So then there was an experiment where they reversed the effects of the Nutrient bath, Thaddeus Ross wanted to stop the experiment but Rick Jones interfered trying to stop him. Then Rick Jones was accidentally knocked into the nutrient bath and became a teen hulk. This stressed Banner that his friend had become The Hulk. He didn't want Rick to go through the same nightmare he had. He got so stressed that he somehow transformed into the Grey Hulk. Grey Hulk fought the Teen Hulk and defeated him. The Leader wanted Grey Hulk and Teen Hulk's powers so he did an experiment where he would transfer their powers into his body. Teen Hulk lost his powers and was cured. He became regular Rick Jones again but the Hulk escaped and stopped their plans. He then reverted into Green Hulk. Sometimes when Banner is angry he becomes Green Hulk but sometimes Grey Hulk. He is a split personality of the Hulk. Whenever Banner's angry inside his mind the Hulk and Grey Hulk are fighting each one wanting to take over Bruce. Whoever wins is the one who Banner turns into.
