I was thinking id give a more concrete answer so here we go!
Marvel:
Spider-man/Peter Parker
Loki Laufeyson/Odinson
Deadpool
Spider-Gwen (Only from into the spider-verse!)
Peter B Parker
Michelle Jones
Natasha Romanoff
(I'm sure there's more but that's my basic list for Marvel!)
Hey this sounds cool! I'm really new to RP and this sounds right up my alley! Only problem is I don't currently have an OC to use, so I would have to brainstorm it with you if you're interested!
