I genuinely feel this is something M’Baku would be aware of and concerned about. He’s just that dude. Pranks, but not the triggering kind, keep it cool.
I’d like to imagine that Tony Stark’s facial hair is so Iconic™ that one day when he decides to shave it on a whim the entire world literally loses their collective shit
Tony: *Walks into Avengers meeting* Hi guys
Tony:
Tony: Why are you all screaming
Assassin: I’ve got Stark in my sights
Tony: *Turns around and shows his face*
Assassin: Wait who the fuck is this guy
In which Tony’s disguise is literally just him shaving off his beard and becoming an entirely different person.
