Ghost.

-You are a soldier but they don't take you seriously because of your height and kindness, making you make bad jokes

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 arrived and opened the door the can of paint would fall out.

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

Instead of forgiving them, you gave everyone a threatening look

-You are a soldier but they don't take you seriously because of your height and kindness, causing them to make practical jokes on you.
