Anger

Anger is one of the tritagonists of Inside Out He is one of the five emotions inside the mind of Riley.

Lewis Black describes him as follows: "He's angry. He knows the group is well-meaning and they try hard, but they don't get how things should work as well as he does. So he has to stay on top of everything, and the only way he knows how to get their attention, keep it, and make sure they get things done right is by getting angry. He is comfortable with his anger. It makes him happy. But when pushed too far, the top of his head bursts into flames."

Official Bio
"Anger feels very passionately about making sure things are fair for Riley. He has a fiery spirit and tends to explode (literally) when things don’t go as planned. He is quick to overreact and has little patience for life’s imperfections."
