Miwa

Miwa was the daughter of Hamato Yoshi and Tang Shen in Teenage Mutant Ninja Turtles (2012 TV series). She, along with Shen, was assumed to perish in the fire that took place following Yoshi's battle with Oroku Saki.

Shredder's biography on some sites indicates that Miwa is his adopted daughter, perhaps alluding to her abduction from the fire.
