Megaman X Dive Offline. Capcom made a gacha mobile for Megaman X that died relatively quickly (or at least feels that way). While it had its focus on the X series, it still had characters from all the other series. The story goes (from what sounds like machine translation), something is causing the X games data to alter and have characters and stages appear in entries they shouldn't, and it's your job to correct it by using Mega Man characters like meat suits as you beat them all to death with whatever weapon you grinded to max.
With the crossover and collabs it got, it can be inferred that data corruption can happen with things outside of the series and not even owned by Capcom. With that, you can mix and match whoever as you use the games own story against the females waistlines; you even have that innocent fool, Rico for making mountains of food, with her power of creation.
