Lucas- a boy in a beret? Kill him now, though his jacket was pretty cool in Platinum.
Dawn- She has to have the ugliest outfit of them all. A pink, plated miniskirt with some kind of spikey black blouse? A hot pink scarf? Those hair pins? A thin bracelet with only two beads? Yuck. The beanie cap? Even worse. Fortunately, her Platinum outfit is much cuter. Unfortunately, I hated her in the anime. How she would always say "no need to worry"- talk about overconfidence! And let's not begin on her please-don't-return... ever Piplup. I guarantee that her next appearance in the anime will have her doing the fire-water pledge combo in a contest. That's not for Dawn, May deserves it!
May is my favorite. I love her hairstyle, her spandex outfit, even the waist pack! Seriously, waist packs should be in style, solely because of her. Light brown hair and blue eyes? That's me! However, I would change a few things with her. One, and this really would just be a bonus for me, would have her hair color be a little bit brighter so it would be kind of a golden brown. Two, lose the bandana- maybe replace it with goggles. Three, lose the family. No little brother. Instead, I prefer it if she was the daughter of Professor Birch like she can be in the games. Four, intelligence. She's kind of... well, not very sharp. But most of that can be cited due to her inexperience with Pokemon. Five, mudkip. I love torchic, but instead of a squirtle, she could've got a Mudkip instead of Brock. Six, have her Eevee evolve into a Jolteon, Espeon, or Leafeon- I'm not too crazy about Glaceon. Seven, no Munchlax. It's okay if she's a bad cook (too bad they didn't make Dawn a bad cook- she always has to be perfect at everything). Eight, catch that little Swablu she befriended in Hoenn. There was so much chemistry there! And I love Altaria! And... that's about it.
