I know, I know, I know that they're not the same person. But they really, really should be, I mean, I know technically Kris didn't exist for Gold and Silver- which are ultimately the ones that were remade. But when such obvious influences of Crystal are present in HeartGold and SoulSilver, I absolutely think that Kris should have been the female protagonist in HGSS.
Lyra is obviously based on Kris anyway; even though her name is Lyra, that's just because Pokémon hasn't done the name-characters-after-the-game thing since.. Well, since Red and Blue. So I'm still going to keep insisting that Lyra is just a poorly represented Kris. And so I'm absolutely fine with the both of them. :P
