Art - Stevie and the Magic Lamp

Tony - a genie in a bottle gotta rub him the right way~
If I weren't too lazy to come up with a good backstory, I'd write about Tony being imprisoned in a magic lamp for irresponsible use of technology a.k.a he was trying to bring humanity into the future too fast. Fast fwd to the future (1940sssss) where the lamp is found by baby Steve, who is probably a sad yet plucky urchin with a thirst for adventure. And well, since Tony's missed quite a bit of the world being in a lamp and all, he agrees to magically make Steve's adventures happen.

Tony takes on the identity of a billionaire benefactor, founds Marvels with Steve, and they have adventures. Eventually, Steve signs up to do war stuff and sets Tony free. Tony stays tho bc who knows alien tech better than he, also he wants to bang Steve. The end.
