I love Sam. Hello. Welcome to the game! Excited to have you! I'm Frost. :)
I've got: Tony Stark (MCU). Basically just the unofficial Mayor of Starklandia, and he's really not even sorry it got named that anymore, even though he sort of was at first.
Clint Barton (616). Clint will know Sam! They're from the same place! High five! Clint's actually from a little later on than Sam is, but he's also massively self absorbed and doesnt pay attention to stuff. Here, he co-owns COFFEE. the coffee shop.
Loki (616) who.. Im not sure how much he's crossed paths with Sam or not. Anyway. It's Loki!
Sirius Black, who is a wizard, Harry.
and John Constantine from the vertigo comics. He's sassy.
