In a world of wings and A/B/O- but not quite, Tony Stark sticks out like a sore thumb. Wings are an expression of the soul, for example Steve Rodgers has white with black tips, meaning he's a good man, but has had dark times. But that doesn't explain his black wings, when he is not who he says he is. Note: No civil war, well kinda of, but not really, Wanda and Pietro are alive but not here. Thor and Bruce never left, and there is no INFINTY WAR AND END GAME.
