I'll use W.I.T.C.H as a kind of jumping off point for tropes etc. that I like, done in ways I like.
>Will
The only good example I've seen of a Tomboy.
Sure, she's not super feminine, and does like sports and so on, but that's so rarely the focus - instead letting her just be a character with complexities.
Also, she's allowed to still have feminine traits, like liking it when a cute boy talks to her, getting tongue-tied - and having breast envy due to being probably the flattest of the group, instead of the usual trope of "ugh these things just get in the way."
>Taranee
>Smart black kid
Sure, she's smart, but she's not cartoonishly so, and despite being booksmart, isn't the biggest nerd on the team, I'd say.
Plus, she actually has a temper and loses control if shit goes down.
>Irma
Holy hell, where to begin.
She's kind of the 'fat kid' stereotype done right - i.e., her entire character isn't about eating, but she still has a healthy appreciation for it.
She's also a jokester, but knows when to shut up, for the most part - that's more than can be said for a lot of 'comic relief' characters.
>Hay Lin
She's kind of inexperienced and curious, as well as a creative, and a fair amount of the time that shit's done in such a way you wanna strangle 'em, at least to me.
>Cornelia
>Haughty, spoiled rich girl
I kind of like this trope to begin with, if only because there's always a redemption arc or similar just built in, and it rarely doesn't go through, and generally always ends up with a better character after.
That, and unlike a tsundere type character, at worst they'll disengage over being a fucking bitch, at worst giving a parting barb.
