Grace
No matter how much I love Harley, I just prefer him as an evil rival. Grace IS not only my favorite coordinator but my favorite non-evil rival of May's
Besides, her being underrated makes her even cooler
it just does for some reason
probably freshness
If I wasn't such a Drew-wh*re, it'd make the voting a lot harder. =P Drew, for all sorts of reasons I'm sure you're not willing to listen to.
If he weren't on the poll, I'd have to say Harley and Grace equally. Grace was amazingness and she's my favorite one-shot coordinator. Harley is just love - he's probably the most unique character in Pokemon to ever grace our television sets. =P
Harley, cause he's Teh Awesome yo. He's my favorite character in the anime period, and he has the greatest pokemon ever. <3
For more minor rivals, Wakana takes the cake. She's the cutest jailbait I've seen in quite a long time. I have a soft spot for star-struck/lovesick fangirls and fanboys anyways. ^,^
Kelly was funny and interesting. She should have been a recurring character.
Harley gets second place, but he is a tad overrated. Grace gets third place, because I have a soft spot for nutjobs. Saori looks cool so she gets Fourth Place. Savannah rounds out the top 5.
Grrrr Harley is soo anoying and Flamboyant at the beggining i couldnt tell if it was a guy or girl. Jessie is my favourite because she was there since the beggining of pokemon.
Harley is just this wacky, insane and vengeful character who never cease to amuse. However, Drew is this young lad who isn't just a rival but also a friend in terms of helping May becoming a more worthy opponent for him.
Drew and Harley are opposites in that case, really. Harley wants to have May fail so badly, while Drew wants her to be better.
That's actually funny considering the colors the two of them have.
You totally forgot Timmy, Joshua, and Ogata.
Timmy had Dusclops, Joshua had Houndoom, and Ogata had Butterfree and Venusaur.
My favorite was Kelly. Super-hot, and super-funny. Plus, Grumpig owns all your souls.
I also liked Savannah and Ogata.
