Original/Multiverse Corruption

Now we say "Original" but that doesn't mean the story is completely original. These tales usually star a new corrupting agent or take an existing one and twist it into the multiverse. Though sometimes it just just a suburb that gets turn into curvy breeding monsters or a lab that goes on lock down with a corrupting gas. Your mileage could very well vary based on your tastes.

But this is a place for more original takes or ones that span multiple series and settings. Or at least start here with the intent of multiverse spanning adventures in corruption.
