Editing Littlefoot's Adventures of TMNT (section)

==Plot==
3,000 years ago, a warlord named Yaotl opens a portal into a parallel universe. The portal's energies grant Yaotl and his four sibling generals immortality, but the generals are turned to stone. The portal also releases 13 immortal monsters that destroy his army and his enemies while becoming the famous mythical monsters of legend as the centuries pass.

In the present, the Teenage Mutant Ninja Turtles have grown apart after defeating the Shredder; Master Splinter has sent Leonardo to Central America for training, where he protects a village from local bandits. Donatello works as an IT specialist, Michelangelo works as a birthday party entertainer called "Cowabunga Carl", and Raphael continues to fight crime at night as a masked vigilante known as the Nightwatcher, which he keeps a secret from his family and friends. The Turtles' old friend April O'Neil now operates a shipping company that locates and acquires relics for collectors, assisted by her boyfriend, Casey Jones.

April travels to Central America for work and finds Leo, telling him that his brothers have drifted apart. She returns to New York City with a statue for wealthy tycoon Max Winters. Leo also returns, and April and Casey deliver the statue to Winters. Winters hires Shredder's former second-in-command, Karai and her ninja Foot Clan to search the city for the 13 monsters before the portal opens again. Raph encounters Casey, who reveals his knowledge of Raph's double identity and joins him in hunting criminals. Winters, who is actually Yaotl, reanimates his four stone generals using technology created by his company.

Leo returns to the Turtles' sewer lair, reuniting with Splinter and his brothers. Splinter forbids the Turtles from fighting crime until they can act as a team again. While training, the Turtles encounter one of the 13 beasts, Bigfoot. The Turtles engage Bigfoot, going against Leonardo and Splinter's orders, and coming into conflict with the Foot Clan in the process. While the Turtles and Foot ninja fight, a fleeing Bigfoot is captured by the generals. The next day, Splinter sees a news report of the destruction left in the wake of the battle and sharply reprimands his sons for disobeying him. Raphael later visits Casey, and they encounter Vampire Succubor, another of the monsters. They witness its capture by the Foot and the Stone Generals but are spotted. Despite a successful escape, Raph is injured and knocked out. Casey takes Raph back to the apartment while April calls the other Turtles for help and realizes the identities of Yaotl and his generals. After being revived, Raph suggests they pursue Yaotl, but Leonardo forbids him to go until Splinter gives his permission. Raphael angrily quits the team and investigates alone.

Leo, Donnie and Mikey plan their next move, and Donatello discovers the next portal will open over Winters' tower. Splinter tells Leonardo that his team is incomplete and that he knows what he must do. After 11 monsters have been captured, General Aguila questions Yaotl's plans for them and the portal. Yaotl reveals that he wishes to free his generals from their stone prisons and break the curse that keeps them alive. The generals conspire to betray Yaotl, wanting to remain immortal. As the Nightwatcher, Raph encounters the Jersey Devil, one of the remaining monsters, but drives it off. Leo, not recognizing his brother, pursues the Nightwatcher across the city, believing him to be nothing but an arrogant thug. After a brief fight, Leo discovers that Raph is the Nightwatcher. The brothers argue about how much things have changed since Leo left. Another fight breaks out, but when Raph breaks Leo's swords and almost runs his brother through with his sais, he flees in a fit of guilt and shame. The generals seize a weakened Leo, intending to substitute him for the 13th missing beast, and Raph decides to make amends by rescuing Leo. As the portal opens, Yaotl discovers his generals' treachery, while Splinter and the Turtles, accompanied by Casey and April, fight their way through the Foot Clan cordon and breach the tower. Yaotl admits to the heroes that he only wants to send the monsters back to where they came from, and the generals reveal that they intend to use the portal to bring in more monsters to conquer the world.

Refusing to betray Yaotl in exchange for serving the Generals, Karai, April, Casey, and the Foot Clan work together, searching for the final monster, the Sea 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 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, cryptically claiming they will soon contend with faces from their past before vanishing. A now-mortal Yaotl honors Splinter and the Turtles, thanking them for fulfilling his wish before dissipating. Splinter places Yaotl's helmet among his trophy collection, as well as Raph's Nightwatcher helmet and Mikey's "Cowabunga Carl" head. As they return to their roles as the shadowy guardians of New York City, Raph says that the Turtles will always be brothers.
