The Four (tmnt)

This story takes place after and before the TMNT movie from 2007* Calla and her four sisters were walking home one night when they saw a brain thing crawl in front of them. They followed it and it ended up being trap set by the Foot, and they had mutagen put into their blood stream. Their mother, scared that their father, a local scientist would experiment on their daughters, gave them away to a girl who offered them shelter. Little did she know, she gave her daughters away to the Foot Clan, just as they planned. But they are still being watched from another group, who are awaiting their chance to take them away and save them from the evil minds of the now awakened Shredder.
