Perhaps I'm looking too far into this, but what physical composition of a Pokemon's body cause it to resist and be weak to different elemental forces? It makes sense that Regirock or Registeel would be rock and steel types respectively, as that it what their bodies are made of, but Chimchar obviously isn't made of fire.
What would cause a Normal-type Pokemon to have no real defining elemental features, yet cause it to be weak to fighting attacks? Why is it that Normal and Fighting attacks, while typically physical, do not harm Ghosts, but punching it with a fist of fire will damage it normally? Why can a Pokemon who's body is made of Rock and Ground swim casually about across a sea, yet when hit with a blast of water, take gratuitous amounts of damage? I'd like to see better thoughts than "because it's Pokemon".
