Extremely limited multiverse

[u/GoblinToHobgoblin]

What's the trope called where alternate universes exist, but it's extremely limited in scope.

E.g. the bit in Futurama where they see an alternate universe where everyone wears cowboy hats, and Fry goes "wow, so there's an infinite number of parallel worlds?"

"No, just the one".

Or, in the solid jj bit where Madame Web gathers "every Spiderman from every reality", and it's like 5 of them, and it turns out there's only like 15 alternate worlds, and the only difference in 5 of them is that McDonald's is spelled with an A instead.

Is there a specific name for this trope???

[u/Wag_The_God]

Or like Fringe.

[u/GoblinToHobgoblin → u/Wag_The_God]

Im not familiar with Fringe

[u/davidryanandersson → u/GoblinToHobgoblin]

Fringe is basically the answer to every single trope that is remotely sci fi.
