Unexpected Gamora

I decided to screencap Wreck-It Ralph 2 and I realised one of the little avatars walking around is Gamora!

There she is in the middle! And that’s Darth Maul poking his head out at the bottom and Iron Man is in the crowd too.

Though that does rather raise the question, since the little square people are meant to be “real” internet users in the movie, why are all these characters who are also presumably fictional in Ralph’s world walking around using the internet? Unless in the terms of this movie all Disney IPs are in fact real characters/people who just happen to live on the Internet? (See: the princesses.) But in that case why are Gamora, Maul etc square avatar thingys instead of looking how they do in their respective movies?

(My head hurts.)
