Having gone unnoticed by many in the past, Supernova has made a successful return recently thanks to their project group collaboration with T-ara for their TTL promotions. For the Countdown Heroes segment on the 15th October episode of Mnet's M! Countdown, there was no Battle nor Shinhwa, as all 6 members of Supernova took to the stage and performed a cover of Shinhwa's classic hit, Perfect Man. Check out their neat performance.
