chunk: Having refused to betray Yaotl in exchange for serving the Generals, April, Casey and the Foot Clan work together, searching for the final monster while the Turtles fight the Generals. Splinter and Yaotl fight off numerous monsters emerging from the portal. April, Casey and Karai arrive at the tower with the last monster, the Sea Monster. The Sea Monster crashes into the Generals, dragging them into the portal before it closes. Karai warns them to enjoy their victory while it lasts, claiming they will soon contend with a familiar foe, which the Turtles suspect to be the Shredder. She and the rest of the Foot Clan depart. Yaotl, now mortal, honors the Turtles and Splinter, thanking them with his dying breath for fulfilling his lifelong wish. Splinter places Yaotl's helmet among his trophy collection, as well as Raphael's Nightwatcher helmet and Michelangelo's turtle costume, and the film ends with Raphael narrating that the Turtles will always be brothers.
