It is the fourth animated series in the Teenage Mutant Ninja Turtles franchise. The series premiered on Nickelodeon on July 20, 2018, with premieres later moving to Nicktoons, which aired new episodes until August 7, 2020.
 The series was announced by Nickelodeon on March 2, 2017, and was initially scheduled to run for at least 26 episodes. This re-imagined series has the Turtles go on new adventures as they seek to unlock the mystical secrets of New York City and their own powers to save the world from evil.
 On July 27, 2018, Nickelodeon renewed the series for a second season consisting of 26 episodes before the official debut of the first season. Partway into the production of this season, however, it was shortened in length to 13 episodes. The final episode aired on August 7, 2020. A feature film sequel was released on Netflix on August 5, 2022 following the series finale.
 Deep in the sewers of New York City, four mutant turtle brothers lurk. Raphael, Donatello, Leonardo and Michelangelo (calling themselves the Mad Dogs) are in their early teen years and the brothers go on new and exciting adventures. They tap into their mystic ninja powers to learn to work together as a cohesive unit and become a team of heroes as they navigate the modern world and other hidden realms. The brothers get a whole new look, new weapons, and new powers as they discover the hidden city beneath New York and find time for a slice of their favorite pizza.
 In the first season, the turtle brothers, along with their friend, April O'Neil, meet an evil alchemist named Baron Draxum, and the dangerous Foot Clan. They also learn of their Master Splinter's secret: that he was once martial arts expert, and movie star, Lou Jitsu. They must collect pieces of an ancient dark armor called the Kuroi Yōroi to prevent the Foot and Draxum from resurrecting the Shredder, a demon once banished by Splinter's ancestors. 
 In the second season, the brothers face new and old enemies, most notably the evil Shredder, and must stop him from destroying the world. In the process, they must also help Baron Draxum discover his own better nature.
