Vadivelu is nicknamed Vaigai Puyal (the Vaigai storm, after the river Vaigai, which flows through the city; Puyal could be symbolic of his ability to 'bring down anything like a storm'). Starting as a sidekick to the famed Goundamani-Senthil comedy duo, he rose to prominence after his role in Kadhalan. His Madurai Tamil accent (Tamil spoken in southern Tamil Nadu) is usually a perfect foil for his roles in Tamil movies with a village background or a simpleton in a city.
