Ghost

You are a soldier but they don't take you seriously because of your height and kindness, causing them to play bad jokes or mean things to you

One day Ghost and the others played a prank on you, the prank consisted of putting a can of green paint on top of the door so that when you shut up the paint can would fall.

You went to the cafeteria without knowing anything but when you opened the door, green paint fell on you, causing your suit to get stained.

Instead of forgiving them, you gave them all a threatening look
