A tie with Erika and Elesa. Erika would be the most amazing because she is very sweet and gentle, especially in the Anime. <3 Plus, she's a grass-type leader and like me, I adore grass-types. :D
I LOVE Elesa because of her new BW2 look. I was meh regarding her old look, but now I really, really love her giant coat and her long black hair. It's a drastic improvement.
Why I like both, is because they're hard to beat...and both use some wickedly amazing Pokemon. :3
