Fans have already known that "Teenage Mutant Ninja Turtles: Out of the Shadows" will feature villainous mutant warthog Bebop and mutant rhinoceros Rocksteady, but the two don't seem to be the only bad guys the turtles will fight against. A new article from Rolling Stone suggests that classic villain Krang will also appear in the upcoming film.

The article illustrates the interaction between producer Michael Bay and Pablo Helman, a visual effects supervisor who worked on the "Star Wars" prequels. According to the article, Helman is having a video chat with Bay to show the producer the latest version of Krang, mentioning that the creature is a "new-to-the-movies villain who is, essentially, a disembodied brain inside a giant robot."

"So we've eliminated the tentacles. Is it too monster-ish?" Helman says of the character. "He could have some tentacles. I just don't want them coming out of the side. He looks like a stupid octopus," Bay jokingly responds. However, the actor who will play the said character has yet to be announced.

The sequel to "Teenage Mutant Ninja Turtles" will feature the likes of Bebop (Gary Anthony Williams), Rocksteady (WWE fighter Sheamus), Casey Jones (Stephen Amell), Baxter Stockman (Tyler Perry), Shredder (Brian Tee), bureau chief of Organized Crime Rebecca Vincent (Laura Linney) and Karai (Brittany Ishibashi). Megan Fox and Will Arnett return to reprise their roles as April O'Neil and Vernon Fenwick respectively.
