Teenage Mutant Ninja Turtles: Out of the Shadows

One year after stopping Shredder, the Teenage Mutant Ninja Turtles are informed by April O'Neil that scientist Baxter Stockman is working for Shredder and plans to bust him out of prison. As the Shredder is transferred between prisons alongside Bebop and Rocksteady by corrections officer Casey Jones, the Foot Clan attack their convoy. Despite the turtles' interference, Shredder escapes when Stockman uses a teleportation device. Shredder is hijacked mid-teleport, winds up in another dimension, and meets the alien warlord Krang, who reveals his plans to invade Earth. He gives Shredder a mutagenic compound in exchange for finding three components of a machine that Krang sent to Earth long ago which will open a portal to his dimension when united, as Shredder and Stockman have the first piece. Casey tells NYPD chief Rebecca Vincent what happened to Shredder, but is met with disbelief, and decides to go on his own.
