What Role Does Nebula Play in Tony Stark Fanfiction?
She might also be a protector in some fanfictions. Given her combat skills and enhancements, she could protect Tony when he is in a vulnerable state in space or against new threats. Their relationship could be one where Nebula is like a bodyguard, but also a friend who has Tony's back at all times. This would add an interesting dynamic to the story, especially if Tony is used to being the one in control and now has to rely on someone else.
Nebula can play the role of a catalyst. Her presence can push Tony to expand his thinking beyond Earth - bound problems. For example, if there's a story about Tony developing new space - friendly technology, Nebula's knowledge of different alien cultures and technology could be the trigger that sets him on that path.
