What would happen if you took a character with an advanced healing factor like Wolverine,Deadpool or the Hulk and split them in half down the middle, keeping the too halves seprate and then left them both alone for the night? Like this -:-(-------- Would the two halves each regenerate what they needed and become two seprate yet identical beings? Logicly I believe they would. If you look at animals that regenerate like worms and sea stars it would have to be true. I think this is a very cool concept and the only plausible explaination for Wolverine being in so many places at once.
