So since Parrish is a supernatural, and after I saw that trailer, I read up about mythical creatures immune to fire and a lot of stuff came up but one of the more popular and one that i think might work is a Phoenix
They can live to be thousands of years old and still appear incredibly young
They were wise, intelligent beasts
And if they died they would be consumed by flames
Only to be reborn from the ashes
They were hella fine creatures too
But like Peter coming home to Avengers Tower, all tired and beaten and there’s Uncle Bucky picking off magnets on his arm sitting alone because the Avengers are out saving things.
Peter flopping on the couch face first and moaning “Uncle Bucky I need help.”
"What for Pete?
"My boyfriend is trying to kill me, I thought you would be an expert in this field."
Wait, these are actually hella cute questions.
