Sam Winchester your fam wants you over at aiodemods. Chuck from Pushing Daisies, the Halliwell sisters, Rory from Doctor Who, Harley Quinn & Batman, are wanted too.
Also how about Final Fantasy, Glee, Silent Hill, Wicked/Wizard of Oz, and Sky High characters for lines? Some more Justice League members would be awesome as well. Seriously any character from these fandoms would get instant storylines and plot.
