Turtle Power!! / TMNT 1987

What if, the Shredder aka Oroku Saki had a life before becoming the Shredder?

Saki meets a lady named Hope and the two get along very well and started dating then they get married sometime later. Sometime after getting married the two had four girls named Jesse, Jamey, Tasneem, and Cheyenne. Saki was very happy to have a family of his own, he loves his wife and he adore his daughters until he started getting jealous of Yoshi. One day, the Master Sensei arrived at the Foot School and that was when Saki made his move. When the class bowed before the visiting sensei, Saki pinned the back of Yoshi's kimono to the wall with a knife, preventing him from bowing to show respect for the sensei, and everyone considered it an insult. Then, when Yoshi found the knife and pulled it out, they considered it a plot to kill the sensei, so Yoshi was banished from the Foot Clan. Hope was not at all happy with Saki and wanted him to be a man and told the truth but all it was made Saki madder. From then on, Saki took over the Foot Clan and took the once noble clan and turned it into an army of crime while his wife keep him away from his daughters and she has taken the girls away from him by moving away.
