Frieza charges the Supernova
Supernova (スーパーノヴァ) is a more powerful form of the Death Ball and is Frieza and Cooler's strongest attack. The user raises his hand or finger and gathers their energy in the form of a giant yellow-orange, sun-like energy sphere. Once it is ready, the user launches the attack against the target. Like the normal Death Ball, it is mostly used to destroy planets, or as a last ditch-effort to kill an enemy.
History and Usage
[]
Trunks Saga[]
Frieza uses the Supernova against Future Trunks
When Future Trunks had transformed into a Super Saiyan and easily blocked Mecha Frieza's attacks, the robotic tyrant flew in the air and launched the Supernova, attempting to destroy Earth the same way he previously destroyed Planet Namek. However, Trunks had caught the attack without harm. Annoyed at this act, Frieza fired a blast at the Supernova, which caused it to explode. Fortunately, Trunks teleported away from the blast and while Frieza was caught off-guard, Trunks killed him with the Shining Sword Attack.
Bardock: The Father of Goku[]
Frieza had learned of the Saiyan's rapidly growing strength and decided to eradicate them, out of fear that they

would have the power to become Super Saiyans and defeat him.
When Bardock attempted to kill Frieza with the Final Spirit Cannon for the murder of his comrades because of Frieza's betrayal, the tyrant countered with his Supernova. The attack had killed Bardock and destroyed Planet Vegeta as well as the entire Saiyan race (a few Saiyans had survived though, including Goku,Vegeta, Tarble, Nappa, Raditz, Turles, Broly, and Paragus).
The Supernova featured in "The End of Vegeta" was nowhere as big as the one in Dragon Ball Z: Bardock - The Father of Goku.
Cooler's Revenge[]
When Cooler's final form proved to be too much for Goku to

handle, Goku's rage and desperation transformed him into his Super Saiyan form. Battered around and overpowered by Super Saiyan Goku, Cooler launched his Supernova intent on destroying Goku along with the Earth (he even mentions he can gather his energy much faster than Frieza). However, Goku manages to push it back with a Super Kamehameha, sending Cooler and his Supernova into the Sun and it seems that he is destroyed. However in the movie Dragon Ball Z: Cooler's Revenge, it is discovered that Cooler had survived the blast with only half of his head still remaining attached to the Big Gete Star, where he produces thousands of mechanical clones of himself to combat Goku and Vegeta.
Return of Cooler[]
When Cooler had been revived by the Big Gete Star as Meta-Cooler on New Namek, he outclassed Goku due to his new regenerative ability and Instant Transmission technique. Wanting to end the fight, Meta-Cooler launched another Supernova to kill Goku, who at the last second teleported away from the blast via Instant Transmission.
