Example of a good crossover ship is Steven and Marinette (or Adrien I don't discriminate). They surprisingly have things in common and I can actually see them interacting and sharing. Like I know that not only those two would get along, I know they would be good for each other. It doesn't hurt that people who ship them tend to be a lot nicer than .... others.
In the past, I would have said Marinette could be good for Steven and vice versa. After watching Steven Universe Future... I honestly think that might not be the case.
Like yes, the shipping around it is not toxic (so that is a major plus).
 But as characters, I feel like they would be too similar to each other but both need very different things. Steven at the end of SUF is in a state where he needs to focus on himself and not try to get up in everyoneâs business and Marinette at the end of Season 3 is someone that finds herself sort of on her own and needs to avoid the same mistakes Fu did and let others she trusts in.
Steven could find himself sucked into Marinetteâs life and he will once again be in the situation where he is trying to help and fix others.
So, I really can't say I ship it as hard as I use to.
