"A legend goes by in the Mushroom Kingdom, a reason of 2 Mario's co-existing in the same world. There were 3, but this one was important. They would bring terror to the kingdom, and if they weren't stopped so soon by the future, might've destroyed it and other areas. What we know now is that all 3 of the 'Otherworld' are dead. They won't be back as Boos, at least that's what we've heard.
It's nothing to worry about. They're all dead. They can't hurt you."

- The otherworld, 3 dark purple versions of Mario, are scraps of the multiverse creation, an unintentional few characters left in the multiverse hub, but even with so little resources, they survived years until finally taking action against the multiverse hub's creator.
- The otherworld leader could sense the "protagonist energy" (or.. whatever it's called, whatever it was, it made Mario a target) from Mario from a portal away, distracted him with taking Luigi and conquering the multiverses.
- They were only stopped right in their tracks due to time travel, as the world was destroyed, Mario travelled back in time to just when Luigi was saved from Mario, and from there, balance had restored itself, but the otherworld had to be taken care of.
- All 3* of the otherworld are dead. But rumours are going around.
