MarioWiki:Marioverse

The Marioverse is any place that exists in the same world(s) as Mario. The name is a catch-all term used by fans to describe all of the various worlds (and everything in them) that Mario (including his friends and enemies) has visited.

The Marioverse tends to be limited to only game related material (or, anything that Nintendo declares official).

The Marioverse seems to overlap other dimensions, as Link, Samus Aran and Culex appear, clearly not Mario characters, as well as creatures such as Goombas and Piranha Plants showing up elsewhere, Hyrule for instance.

The name is a combination of the words 'Mario' and 'Universe'.
