There have been hero character names in Bollywood that became famous but due to repeat use - like Bharat for Manoj Kumar, Vijay for Amitabh or Prem for Salman.
And then there are characters based on legends or books where the Hero name became very famous - like Devdas, Majnu, Ranjha etc.
But Chulbul Pandey must be the only character name that became so famous with an original character in the first film itself.
There have been female characters like Bobby and Paakeezah that became legendary with their very first and only film. There have been villain names like Gabbar and Mogambo that became unforgettable.
But Salman has created the only original male character in Bollywood that became immortal.
We can easily say Chulbul Pandey is the biggest hero ever created in Bollywood.
