Not counting Ash or Gym Leaders, what are your favorite characters from the game that were brought into the anime? I put this here for when characters like Cheren (he is a GL now, but since he didn't start off as one, I think he can be counted here) and N appear.

I really liked Barry and Bianca since I thought they added an interesting dynamic to the show. It was nice to see them represented and they weren't badly mangled characterization-wise.
