Is Marvel an Omniverse or a Multiverse

Loads of people say Marvel is an Omniverse and loads of people say Marvel is a Multiverse.

Which one is it?

idk is the marvel universe 4 dimensional? thats the dictionary definition of omniverse. multiverse is a realm of being with infinite possibilities

Its a megaverse

It's a multiverse.

Its a multiverse. The Omniverse is the sum total of all universes that exist. Its the premise which they use to allow for cross publisher crossovers.

Above omniverse

@joshmightbe: that makes sense for sure

@ancient_god: There is nothing above Omniverse. Its literally the sum total of everything including all fictional worlds. I'm going by the comic's definition of the Omniverse here.

This.
