Rambo Rajkumar, born Rajkumar, was an Indian fight master/action choreographer. He was the son of TK Parameshwar, who himself was a stuntman. Rajkumar worked in Pudhupettai and Kadhal Kondein and the posthumous release Aayirathil Oruvan.
He earned the prefix of 'Rambo' because of his style of realistic close combat scenes, which resembled Sylvester Stallone's style in the movie, Rambo.
On 26 April 2009, while filming for a project in Hyderabad, Rajkumar suffered from an heart attack and died later that day.
A film released in 2013, R... Rajkumar was first named as Rambo Rajkumar, but the name was later changed owing to copyright issues.
