Miles has always had invisibility and bio-electric stings in all media. I'll be honest I can't think of any powers Gwen has that Pete doesn't, but I admit to not having read as many stories with her.
Spiderverse has made me so use to them as a trio, and though I've only watched an occasional ep Spidey and Friends has backed that up, that it felt kinda weird to me that she doesn't exist in the universe of the PS5 Spider-man 2 game that I just finished. I kept wanting her to show up.
-ZacWilliam, she doesn't really fit in that Universe though sadly, so I don't expect her even in the inevitable 3. Although it looks like they're teasing someone who'd be a good stand in (spoilers for the game so I won't elaborate.)
