Michelangelo, Donatello, Leonardo, and Raphael return to theaters this summer to battle bigger, badder villains, alongside April O'Neil (Megan Fox), Vern Fenwick (Will Arnett), and a newcomer: the hockey-masked vigilante Casey Jones (Stephen Amell). After supervillain Shredder (Brian Tee) escapes custody, he joins forces with mad scientist Baxter Stockman (Tyler Perry) and two dimwitted henchmen, Bebop (Gary Anthony Williams) and Rocksteady (WWE Superstar Stephen "Sheamus" Farrelly), to unleash a diabolical plan to take over the world. As the Turtles prepare to take on Shredder and his new crew, they find themselves facing an even greater evil with similar intentions: the notorious Krang.
