Might not exactly fit here, and I'll probably catch flak for it, but...
Renamon.
Yes, yes, she's only humanoid, but she ends up as Sakuyamon, so I count it. I kinda liked the reserved, cool personality and tough protectiveness and all around bad-assery kinda reminds me of Motoko Kusanagi, but with a more emotional side too, at times.
Then again, I haven't seen the show in years, so maybe it's just the rose-tinted glasses of nostalgia.
