Let's defend the scrappies we actually like! (For those who don't know, a "scrappy" is a character most fans despise)
Here's some of mine:
Relena Peacecraft (Gundam Wing): Some fans despise her because she tends to put herself in harm's way, making her a perpetual damsel in distress. However, I feel that part of her problem stems from her upbringing. She's trying desperately to uphold her family's honor.
Orihime (Bleach): I think she's a very valuable member of the heroes. So what if she gets a little emotional.
Toshiro (Bleach): Oh come on, his sword is a dragon made of ice! You can't beat that!
Naruto (Naruto, of course): I think he's funny and I like his spirit.
