Supernova truly lives up to its name. To use Supernove, the player must repedtly press to fill up a bunch of gauges. If the player manages to fill up all the gauges, Supernova can deal 15 damage to all enemies on the screen. This makes it the most powerful move in Mario's arsenal. However, it costs a hefty 6 SP to use and is recommend to use if Mario is close to a level up.
