Info from bulbapedia Shedinja never has more than 1 hp (probably) FAQ's Q: How do I know what the nature modifier is? A: In some games it tells you if you look at the pokemon's stat spread, for other games just look it up based on what nature your pokemon has (natures do not affect HP). Q: Is this accurate for all generations? A: It uses the formula from gen 3 onward. Stats in gens 1 and 2 use something different (It's kind of difficult to implement) Q: What are my pokemon's base stats? A: Look it up (pokemondb.net is a great source for this)
