works more like this:

Toy Story is a single universe - however it is part of the Disney Multiverse.. Disney Megaverse would include any property Disney currently owns such as Star Wars.

A Universe has the same hierarchy and basic rules, a Multiverse shares a similar "feel" and a Megaverse simply happens to be connected by "ownership".

MLP is technically part of the Hasbro Multiverse and so forth.. complicated doesn't begin to give justice to how mind-bogling this stuff can get.

Basically all alternate-realities and worlds that share a similar hierarchy are part of a Multiverse (so for Villains it'd be universes that have shared cosmic laws of some description) - universes that do not share the same hierarchies but are still owned by the same "company" (or in our case "community") are part of the Megaverse.
