Tony stark:
You were currently running form your dad. Why? Because you took colored sharpies and drew on his suit. Let's just say you were grounded for two weeks.

Peter parker:
You told him that a boy/girl/person had kissed you. He went to find this person because no one kisses his child. He tired to find out who and why you were laughing so much. He felt dumb when you said it was a prank.

Steve rogers/ captain America:
You drew on his face when he was sleeping. He was not happy with that.

Bucky:
You hide his guns.

Bruce:
You don't prank him just because you don't want hulk coming out.

Loki:
Four words. You hide his daggers.
