[Gyarados seems very impressed by this. People that can use Waterfall...?]

He's a Steel-type specialist, right? [Blue drawls, keeping his eye on Archie while he scritches Arcanine.] ...Well, I woulda figured not seriously, anyway. He's a Champion, after all. [And Archie is.... Well, he supposes he should figure that he's somewhat competent, if he was leading a team. Was he even as strong as Giovanni had been?]

I don't know too much about Hoenn's Pokémon, but Johto has a Steel-type Leader now, as well. Steel's reclassification was pretty recent, so does that mean he also used Rock types before?
