Dragon Ball Super: Super Hero Plot Summary and Synopsis
On Beerus’ planet, Goku and Vegeta continue their training under Whis, now joined by Broly to help him control his rage. Meanwhile, on Earth, the revived Red Ribbon Army, led by Commander Magenta and Staff Officer Carmine, recruit Dr. Hedo, the grandson of Dr. Gero, to seek revenge against Piccolo and Gohan.
Under Hedo’s guidance, the Army creates two new androids, Gamma 1 and Gamma 2, to act as superheroes in the public eye. They deploy Gamma 2 to attack Piccolo, who loses the fight.
Piccolo follows Gamma 2 back to the Red Ribbon Army’s base and discovers that Magenta and Hedo are working on a new android named Cell Max, a new and improved version of Dr. Gero’s ultimate weapon, Cell.
In order to lure Gohan into a trap, Magenta decides to kidnap his daughter Pan. A disguised Piccolo, having learned of this plan, volunteers himself for the kidnapping party, and intercepts Pan, who agrees to go along to get her father to pay attention to her. After learning that she has been “kidnapped”, Gohan leaves his studies and launches a full-scale assault on the base alongside Piccolo, who has used the Dragon Balls to attain a new form dubbed “Orange Piccolo”.
Unleashing his “Ultimate” form, Gohan battles Gamma 1 and overwhelms him while Piccolo battles Gamma 2 using his “Orange Piccolo” form. Piccolo defeats Gamma 2 before stopping the fight between Gohan and Gamma 1.
After seeing Carmine trying to kill Pan, the Gammas have a change of heart and help Gohan and Piccolo save her.
In a fit of rage, Magenta prematurely activates Cell Max, causing him to be released as a giant, rampaging monster. Hedo kills Magenta to stop this but is too late. Gohan, Piccolo and the Gammas, joined by Goten, Trunks, Android 18 and Krillin, battle Cell Max. Goten and Trunks fuse into Gotenks and, despite botching the Fusion Dance, are able to crack Cell Max’s skull, revealing that he does not have a healing factor like the original Cell.
Gamma 2 sacrifices himself to injure Cell Max, destroying his left forearm. Combining his “Orange Piccolo” and “Great Namekian” forms, Piccolo battles Cell Max but is ultimately defeated. This causes Gohan’s inner rage to finally erupt, unlocking an evolution of his “Ultimate” form called “Gohan Beast”.
As Piccolo holds Cell Max in place, Gohan kills him by destroying the nucleus in his head with a supercharged Special Beam Cannon.
Dragon Ball Super: Super Hero Ending
With the battle over, Gamma 1 and Dr. Hedo renounce their evil ways and join the Capsule Corporation.
Dragon Ball Super: Super Hero Ending Post-Credits Scene
In a post-credits scene, Vegeta defeats Goku by landing a soft hit after both fighters exhausted all of their strength in their sparring match. Vegeta gloats about his victory as an awestruck Broly and Lemo look on, much to Cheelai’s irritation.
