In the 2007 animated film, Karai is a new character in the film series, based on Karai from the 1990s comic series. Voiced by Zhang Ziyi and shown wearing a full-body black armor with a hood on her head and a short cape, Karai is the Japanese Foot Clan boss and has came to take over the New York Foot after the Shredder's death, acting as mercenaries. Karai was one of favorite comics characters of the writer and director Kevin Munroe and he "was the one who really pushed for Karai" to appear in the film. Talking about a possible sequel to the film, as well as new comics, Munroe said he would "love to see us explore the Karai and Foot Ninja thing a little more."
