Lance and Steven!!
Steven was oddly nice to you throughout the game and that HE's the champion that stands between you and eternal glory (well...) is somewhat of a smack in the face ^^
Well, Lance in G/S was even better. I was happily surprised when I met him in the game, since he's one of the grrreeat elite4 in R/B/Y. That HE was the champion was just awesome. And a champion that uses dragons... that has to be the best ^^
