Fans are excited to witness Hrithik Roshan again as India's favorite superhero Krrish. Hrithik's father Rakesh Roshan is currently planning fourth part of the franchise and Hrithik officially announced the project earlier this year with a post that read, "The past is done. Let's see what the future brings. #15YearsOfKrrish #Krrish4." Just like it is with every other big budget project, this one also has several rumors associated with it. These include Hrithik Roshan playing the antagonist and involvement of time travel in the plot.

A source told Pinkvilla, "The makers are trying to build the universe in a way that the world of Koi Mil Gaya and Krrish come together. While the idea of bringing Jadoo back is in place, the makers have zeroed in on the concept of time travel for this one. Krrish as a franchise has a strong sci-fi backdrop and there has been a gradual significance of time through all the films. In Koi Mil Gaya, Rohit Mehra uses his father’s equipment to communicate with Jadoo, whereas in Krrish, Rohit himself develops a Time Travel Machine, the object of interest. Time travel will be key to the story of Krrish 4."

The franchise previously toyed with the idea of time travel briefly in the film 'Krrish' where Rohit Mehra builds a computer which can see future.
