“Okay, let’s do this one last time. My name is Sunset Shimmer, I was bitten by a magically-altered spider, and… Yes, I said magic. If it was radioactive, I’d have tumors, not superpowers.”
The Multiverse, being infinite, would include a reality where Sunset Shimmer is a spider-themed superheroine. Hopefully not also one of the casualties of that dimension-hopping villain.
either way its a win win or both.
