Our universe would be on the list. Marvel's 616 and 1610 (ultimate universe). And then those pesky parallel universes closest to us that have been bumping into ours of course.

"First evidence of other universes that exist alongside our own after scientists spot 'cosmic bruises' Scientists say that they have found evidence that our universe was 'jostled' by other parallel universes in the distant past. The incredible claim emerged after they studied patterns in the cosmic microwave background radiation (CMB) – the after-effects of the Big Bang. They say they may have found evidence that four circular patterns found in the CMB are 'cosmic bruises' where our universe has crashed into other universes at least four times. The findings are based on the complex theory of eternal inflation for our universe. This theory holds that out universe if only one bubble in a larger cosmos and that other universes,which will have different physics to our own, all exist at the same time. This is also know as the the multiverse theory."

Also, I'm pretty sure the technodrome has a portal to dimension x, which is the coolest name for a universe ever.

I see bubbles burst in a boiling pan of water; doesn't mean another boiling pan of water bumped into it.

...

but it is incredibly exciting
