Ever since the early days of their speculatory What If series, Marvel has always enjoyed creating alternate universes to make you laugh, cry, or simply shake your head in complete disbelief.
And they never disappoint. Over the years the House of Ideas has provided us with lands filled with zombified pigs, radioactive incest, and a planet that is entirely New York - and those aren't even the weirdest worlds thus far.
Although there's plenty of space for even crazier universes to appear, as currently Marvel canonically have twenty trillion universes - so they definitely don't have to worry about running out of space for their unconventional creations. There's freedom to create complicated worlds with clever, twisting lore, or to just create the most hilarious concept possible, and creators appear delighted to do both in equal measure.
It's reassuring really, to know that every strange and silly possibility you've ever thought about is either real already, or about to be real at some point in the future. And - all of the kind of gross universes aside - that's something you have to love just a little, even if it does mean you occasionally have to see an undead spider-porcine in exchange.
