I always thought Mario and Peach were lovers, as in a romantic relationship. Maybe they are just friends for now with romantic feelings for each other but afraid to tell each other. It is possible they could start dating in the future.
If Marvel does bring back the Eternals and Inhumans it would be a second chance for them to the teams better, in a way many of the fans want.
Though personally, I like the Eternals. I thought it was a good movie. The Inhuman series was ok, I like it but it was not the best.
The 2008 Increadable Hulk was very bad, at least for many fans, but the kept bringing the character back. Maybe they can do the same with the Eternals and Inhumans.
