Your name is JACK FROST and you are friends with the WIND.
Your fellow Guardians will never stop finding strange the fact that you talk about it as a real, physical person, but that's ok. They wouldn't understand.
Because the wind was the only friend that answered your calls in three hundred years; he taught how to fly and make the best pranks: the wind is a pranking master and a great teacher.
The wind has no voice of his own, but you can almost hear his laugh when he lifts you up and his howl when something angers him or makes his sad.
Fedoras make him sad, pipes make him sad, harlequins make him sad and you don't dare to ask why. After all, he never asked you anything.
You know the wind and the wind knows you: that's why you're not surprised when you happen to see in the corner of your eye a blue silhouette, with a long windsock hood: he's got a bucktoothed smile Toothiana would love and bright, bright blue eyes.
He's the wind, and he's your best friend and you don't care about anything else.
Because, SERIOUSLY, no one crossovered this yet?
I want to write more, but I have too many projects running and I don't have enough time to do everything.
Feel free to pick this idea and write something of yours, I'd like to see it done.
