Master Splinter hosts a private fighting tournament for his sons, Casey Jones, and April O'Neil before receiving a distress call from Professor Honeycutt, who has been captured by the Shredder. Karai reveals that Shredder plans to force the Fugitoid to build a Transmat device capable of teleporting his armies anywhere on Earth. After the Turtles defeat the Shredder, Karai admits she manipulated them to seize control of the Foot Clan from her father; Leonardo's timely kick sends both onto Honeycutt's activated Transmat, banishing them to parts unknown. A companion comic book fills in additional context: Donatello repurposes Renet's Time Scepter to reach Shredder's Tokyo base, but repeated malfunctions scatter the team across eras—an Old West outpost, a feudal Japanese castle defended by Oni warriors—and accidentally deposit a sewer-dwelling alligator into an Amazon rainforest along the way.
