Lelouch has the attitude of a good Prince Adam pre-turning into Beast / Kuzco from Emperor's New Groove, but not quite the heartlessness... He'll be the chick from Ratatouille. *shot*
Allen can be Aladdin. X3
Orihime is JACK from Nightmare Before Christmas. :D WHAT'S THIS? I WANT TO BE SANTA. LET'S MAKE OUR OWN CHRISTMAS!! Or a slightly grown-up Lilo from Lilo & Stitch. She's got all the imagination AND the wacky pet!
Roxas could probably pull off WALL-E. Wwwwooooah!
Fran is a radically different but thematically similar take on The Little Mermaid. X3
So can Gino-- *shot* Er, dude from Pocahontas?
Okay, let's see. How about -- what is the type (wink wink nudge nudge) of each of your characters?
