[An interesting discussion popped up in the forums a couple of days ago, and it seems worth showcasing!]
I was just wondering. If a Pokémon was missing something, like an eye or a tail or a limb, would they regenerate the missing part by evolving? I mean, technically some Pokémon gain extra limbs and things by Evolving. But when something is just changing slightly, like a tail getting slightly longer and thicker between Charmander and Charmeleon, would it grow a totally new tail if it had been severed as a Charmander?
This is all just curious ramblings and I know my example isn't very good because isn't Charmander supposed to die without his tail flame? Anywho interested in what yall think as it may come up in a future roleplay for me!
