So, the girls decide that they need their voices tuned up(and voice actors don't last forever...)
Only, they make the mistake of going to AMBIA'S DENTISTRY, and the lot of them end up with their voices being stolen through the horrors of fudged Hokuto Shin Ken(actually Ambia did something bad, summoned the Lord of Nightmares, and the voice actors got assaulted with a shovel through the 4th Wall...)
SO! A whole new line-up of voice actors are needed.
Who's your pick for each and every Disney Princesses'
1) Speaking voice, and,
2) Singing voice?
3) Add in berserk mode and cussing voices, if you want.
GO!
