Having watched a lot of anime myself, I admit the mere initial juxtaposition sort of tickles my fancy, but I don't quite seem able to think of Ahsoka as an "overachiever" the way I can see that as a defining trait for Asuka. Maybe it has something to do with "dysfunction" and "family issues" being a common theme in Evangelion for me, and I can't apply either of those to Ahsoka.

Now, mind you, I'm at least wondering about some hypothetical "dysfunctional female student for Anakin," and how, if she hadn't just been summed up by fandom as "an attempt to one-up her teacher," everybody would be watching for signs of her inevitable coming to pieces... although balanced against that is the amusing thought that, beyond Anakin, Ahsoka does have a sort of "family tie" in her connection to Plo Koon, Dave Filoni's favourite "well, he looks neat" background character...

(I do have the three season sets for Avatar: The Last Airbender now, and I'm looking forward to seeing them for myself one of these days, but right now I suppose I have the feeling I should finish rewatching Batman: The Animated Series first...)
