Unfortunately, I think I used up all the other characters I know from Inu-yasha... and like you I don't wish to turn this into an anime thread and alienate those who may not be interested. Or further exhibit my geekdom in that subject.. ahem... anyway...

Let's American Animation with us!

The Incredibles:

Mr. Incredible:
HPF... always ready to save the day in a pinch.

Elastigirl (Mrs. Incredible):
jmcc... keeps it all together no matter what the situation.

Violet:
groundedsidhe... can do the pouty face and reluctant hero bit.

Dash:
dangertoy... chock full of high powered energy!

Jack Jack:
Percy... can't quite place why, but he might fit the part... seems the type that little old ladies would react to him the same as they would a baby, the whole "aww..." and pinching of the cheek bit. Plus I've heard his skin is as smooth as, erm... a baby's bottom?

Syndrome:
WinterGnat or Coffeebot... either would be good at playing the vengeful adversary, I think.

I can't think of a good Frozone... Ideas? We need the costume designer too...
