This is a very interesting question! Unfortunately I'm going to have to be rather boring in my answer, since in all honesty, they don't remind me of anyone. It may simply be that I don't generally draw a lot of comparisons between characters cross-canon.

I definitely do see that they have some characteristics that other characters I've loved share. On the whole I still see them as pretty unique, though.

Now I will have to go think about why I am so odd. ;-)
