This is one of those posts that make me wish we could tag multiple tildes. Because this would apply to ~tv, ~movies, ~comics, ~games, ~books, and ~anime, with possibly even more.

A long time ago I read an article about weird crossovers, and it made the point that thanks to unrelated crossovers and six degrees of separation, the Archie comics Sonic technically existed in the same universe as... Some popular live action shows, because that show had a crossover with some other show that crossed over with Sonic. Obviously not really, but it was a funny thought.

I failed to find the article I remember, but my brief search did bring up the Tommy Westphall Shared Universe, which comprises 400+ shows thanks to various crossovers, cameos and in-universe references. There is a whole fandom wiki dedicated to it. There's also this site that lets you search for connections between TV shows. The site's description from DuckDuckGo is "Easily search and find the relationship between shows in the Tommy Westphall Universe and beyond." It's silly, but fun!

Thing is, most of my cursory searching into it has people focus on live-action TV and movies. And... Well, like I said at the start: the article I remember reading made a connection between Archie comics Sonic and some live-action show thanks to some crossover.

Since that first article, I've wondered off and on about the weirdest crossovers out there, and just how weird of a shared universe could exist. I don't want to limit it to one or two mediums, I want to find crossovers that can transcend mediums! Comics, TV, games and more!

So: what are the weirdest crossovers, cameos and in-universe connections you know of? What are the wildest connections we can make? And, for bonus fun, what are the ramifications of shoving all these wildly different series into one ridiculous universe?? how many different apocalypses can we shove into it
