Irma from TMNT (2012)
In the 2012 cartoon series Teenage Mutant Ninja Turtles, Irma Langinstein (voiced by Kate Micucci) is a robot built by the Kraang Hive Mind who takes the form of April O’Neil’s teenaged punk girl friend. Irma is one of the enemies faced by the Teenage Mutant Ninja Turtles.
Casey Jones from TMNT (1990)
Casey Jones (Elias Koteas) was first introduced to the Teenage Mutant Ninja Turtles in an altercation with Raphael. The two of them actually fought each other in a New York City park, just after Raphael stopped some punk from stealing a woman’s purse and Casey was about to beat them to a pulp for that whereupon Casey turns his aggression on Raphael. The 1990 movie version dresses slightly differently from the late ’80s cartoon Casey Jones.
Splinter
Splinter is a mutant rat and an important character in each incarnation of the TMNT franchise, as the teacher, martial arts instructor, and foster father of the Ninja Turtles. In some incarnations, he is a mutated or reincarnated Hamato Yoshi; in others, he was Yoshi’s pet rat who is sometimes known as Hamato Splinter.
