Mohan was called in the industry as the 'silver jubilee hero' in the 1980s for almost all movies featuring the actor witnessed a fantastic run. His nick name in popular circles is 'Mic' Mohan owing to the fact that he performed a stage musician and all of his movies had a scene in which he performed with a hand-held a microphone in his hand. He holds the record in the industry for giving 25 silver jubilee hits, a feat not matched by many industry greats. However, Mohan disappeared from the filmdom by the late 1980s following a series of flops. Although his debut was "kokila", a Kannada film directed by veteran Balu Mahendra, his first Tamil appearance was Moodu Pani (a guest role). This was followed by Nenjathai Killaadhey, a masterpiece of director Mahendran, which started the short yet a full scale peak career of Mohan, which lasted almost 8 years. Nenjathai Killaadhey ran for a year and won best cinematography national award for Balu Mahendra, after which his films began to be either silver jubilee or over 200 days most of the time.

Almost all his film were good musical albums (thanks to Maestro Ilayaraja), which feature songs that are still remembered after 25 years. Mohan is still talked about every time a conversation springs up for 80s films or Ilayaraja's songs
