Krrish 3 (2013)

Rohit Mehra (Hrithik Roshan), who is a professional scientist now, is living a happy life in Mumbai along with his son Krishna (Hrithik Roshan) who is now married to Priya (Priyanka Chopra). While working in the laboratory, Rohit invents a device to bring back the life of dead tissue using solar energy through reflections but failed to complete it because of the high intensity of sun rays. Priya works as a journalist for Aaj Tak whereas Krishna is struggling hard to keep a steady job while helping the city with his superpowers as the superhero 'Krrish'.

Somewhere in an isolated area, the owner of Kaal laboratories, Kaal (Vivek Oberoi), who has extraordinary telepathic powers, is completely handicapped with his body except his brain and two fingers. He has been creating powerful human-animal mutants (or Maanvars he calls them) using his DNA, particularly the ruthless chameleon mutant Kaya (Kangana Ranaut) who can assume any form she wants. Kaal has been trying hard to cure himself but has been unsuccessful thus far. He dreams of making billions by first creating dangerous viruses using his DNA, spreading them in densely populated areas and then selling his own antidotes.

Kaal chooses India as his next target and with Kaya and other mutants' help, he spreads his newly created virus in Mumbai which creates havoc among the city. Rohit, Krishna, and Priya remain unaffected by the virus. Rohit manages to create an antidote using Krishna's blood and Krishna spreads it throughout the city via explosions for quick effect. For this, Kaal's mutants attack and thrash Rohit's laboratory but Rohit and Priya are saved by Krrish. Priya is injured and hospitalized while one of the mutants is also injured which is kept in scientific custody by Rohit and his team. To find out how an antidote was developed without using his own blood, Kaal kidnaps Priya who is pregnant with Krishna's child and Kaya takes Priya's form. Rohit and Krishna are informed that Priya has lost her child. Afterward, Kaya starts living as Priya with Krishna and seeks for the antidote formula. Rohit departs to Singapore to explore some answers after he finds out that the virus has a link with his own DNA and Kaal laboratories as well. Meanwhile, Kaya develops an attraction towards Krishna but he soon discovers her true identity and reveals himself as Krrish to her. Kaya decides to help Krishna and discloses that Priya and her child are still safe in Kaal's hideout.

In Singapore, Rohit is kidnapped by Kaal's men. Rohit unveils to Kaal that he was kidnapped by Dr. Siddhant Arya (Naseeruddin Shah) who tried to create a synonymous avatar of the former but got only a disabled child and donated him into an orphanage where the boy was adopted by a wealthy family, who eventually grows up to become Kaal. Kaal cures himself by using Rohit's body serum. Krishna saves Priya after killing the mutants and finally reaches the correct hideout with Kaya's help where Kaal kills both of them. Kaal then surrounds himself completely into a steel body due to his powerful magnetic powers and departs to Mumbai in search of Priya meanwhile causing destruction to the city.

Angered by Krishna's death, Rohit decides to bring Krrish back to life by using the device invented by him but sacrifices himself to absorb the high intensity of sunlight. Krrish, now thrice as powerful as before, comes after him and saves Priya. Krrish, unable to crush Kaal after brutally fighting with him, concludes that the latter could be demolished by melting his steel body. He quickly adjusts the mirrors for reflection and points Rohit's device towards Kaal whose steel body melts finally. The film ends with Priya delivering a baby which also shows signs of extraordinary power.
