Film adaptation
A film adaptation of the series, titled TMNT: Battle Nexus, was released on Netflix on December 25, 2034. The film, a crossover with the 2003 and Rise of the Teenage Mutant Ninja Turtles series, would see the Turtles and their counterparts from other realities being transported to the Battle Nexus. According to director Sage Cotugno, the other series were chosen due to respective desires to explicitly acknowledge the 2003 series and "see the Rise versions react to more traditional turtles". The filmmakers would also avoid using the 1989 versions due to the characters having already being used in previous crossovers.

Trivia

 * This is the second TMNT series to have co-creator Kevin Eastman involved in a creative capacity; he previously wrote a season five episode for the 2012 series.
 * This is the first animated series to feature Venus de Milo, albeit under a different name.
 * According to Eastman, the character was renamed "Diana" due to being the name of both a Renaissance artist (much like the four other Turtles) and Wonder Woman.
 * Eastman said the creators were "extremely mindfull" of the criticisms regarding the character, to the point of creating "a list of everything that people hated about her that we must avoid".
 * This is the second animated series to have Splinter be a mutated rat as in the comics, after the 2003 series.
 * Five cast members previously worked together on The Owl House: Zeno Robinson (Hunter/Leonardo), Mae Whitman (Amity Blight/April O'Neil), Kevin Michael Richardson (Tarak/The Shredder), Eric Bauza (multiple characters/Splinter), and Jim Pirri (Alador Blight/Krang). Composer T.J. Hill also worked on the first season of The Owl House.
 * Eastman felt that the focus on Mei and havimg the Turtles be seasoned crimefighters with an already established rogue gallery allowed the series to stand out from the previous shows.
