Hmm, I have a couple.
May: Hoenn was and is my favorite region. Ruby version was the first pokemon game I ever got. I feel like in the anime, May just spices it up with her personality! She is the best female character by far! I will never forget the Hoenn saga <3 I finished it and I'm rewatching it for the 3rd time, because I just LOVE May so much!
James: I always loved how James would always go on and on about bottle cap collection. His accent always cracks me up! And how he's probably the dumbest member of team rocket! I'm very sad that now in B+W Team rocket is all serious and stuff. It totally ruins them! But what I do like is that they actually have a chance to WIN!
Brock: I never understood why his eyes were always closed. But something I LOVED in the hoenn saga was when ever May and Ash and Max had to do something, they always asked Brock to stall. When Brock stalled he did his little Mexican Dance with Ludicolo <3
Iris: One of the new characters! Ghee, I love her sass towards Ash and how she always calls him a 'little kid'. Her hair makes me laugh, especially when Kibago (Axew) leaps into her hair :3
Dawn: At first she was my LEAST favorite character. But after I watched Diamond and Pearl, I love her! She isnt anything compared to May, but Dawn is funny and I love how in the beginning, she and Ash did nothing but bicker and fight.
