The Hulk’s personality is one of childishness, rage, and destruction. When Bruce Banner transforms into the Hulk, his physical abilities are greatly enhanced, but his mental faculties regress to a state similar to that of a child.
It’s difficult for him to remember things, and he’s extremely emotional and lacks foresight.
Just like Hulk, you are mischievous but when it comes to a very serious matter you are strong and take responsibility for your actions.
