Ninja Turtles: The Next Mutation

The Next Mutation was first announced in late 1996 through ninjaturtles.com.

Notably, April O'Neil and Casey Jones are absent, and in a departure from other TMNT continuities, Leonardo states in the second episode that the Turtles are not blood-related, while other media explicitly present the Turtles as biological siblings.

In the United States, the show first aired from 1997 to 1998 on Friday afternoons on Fox Kids.

In the United Kingdom on BBC from October 1998 to Late March 1999 with a repeat from 1999-2000.

The series also screened on Fox Kids UK from 1998 to 2003 and then on Kix! from 2012 to 2013.
