VS. Dr. Hedo

is the 90th chapter of the Dragon Ball Super manga.
==Summary==
In the Cricket district, Krillin continues his investigation on the mysterious zombies that were previously spotted on Butterfly Mountain, eventually finding them in a convenience store where he promptly arrests them. 
Meanwhile, Goten heads to the city on the Nimbus, getting on a bus a few stops away from school in order to cover his trail as the superhero Saiyaman X-2. After being asked by Fyler if he can set her up with Trunks for the upcoming school dance, the bus comes to a screeching halt due to the sudden appearance of Beta 7. Beta 7 calls out Goten, knowing his alter ego to be Saiyaman X-2 who proceeds to exit through the back of the bus before returning in costume, unaware of the coincidence that all of his other classmates seem to notice. Goten then effortlessly takes down Beta 7.
At school, Mai asks Trunks to the dance, much to his surprise, after learning from one of his friends that he has booked the superhero Cleangod for the dance. Using a tiny insect spybot, Dr. Hedo overhears the news and becomes elated, quickly deciding to create a female student android as a date so that he can attend the dance himself and meet his hero.
An observant Mai soon notices the spybot and pulls Goten to one side and informs him of what she knows about Dr. Hedo and the androids that are being sent after him as well as the plan to lure him out using Cleangod so that she can capture him herself. When Goten asks if that was the reason why she invited Trunks to the dance she says yes, to which Goten feels bad for Trunks who believed that the invitation was genuine.
Once the dance begins, Mai arrives in a suit of armor whilst Trunks wears a fancy suit. He hands one of the attendants a bag to hold on to containing the data disc belonging to Dr. Hedo and makes his way to the stage as he awaits the appearance of Cleangod. Next to Trunks, stands Dr. Hedo, another eager fan, and they briefly share their love for the superhero just as Mai pulls out a weapon on the doctor but is halted by Beta 1 who takes it from her.
Krillin and the police then arrive, having been tipped off by Mai and orders everyone to freeze but Dr. Hedo manages to escape using a smoke launcher concealed under his sleeve and races off in a vehicle while Beta 1 is able to regain the data disc after stealing the guests' bags. 
Krillin, Goten and Trunks take off after the scientist by air with the teenagers now donning their superhero costume. After Krillin explains to them that Dr. Hedo is the grandson of Dr. Gero and learn that the infamous Red Ribbon Army is after him, the trio catch up to him at another of his secret labs. There, Dr. Hedo releases Dinodroid 1, a dinosaur that has been turned into an android that far surpasses that Alpha and Beta series of androids.
Working together, Krillin is able to stun the android with a Destructo Disc to the back of the neck long enough for Goten and Trunks to finish him off after turning Super Saiyan and using the Cyclone Style! Tornado Double Hurricane technique. Krillin then arrests Dr. Hedo but is unable to find the data disc as he has since discarded it, no longer needing it as he had long since memorised its data anyway. The doctor is then sent to prison for three months for his crimes of stealing bodies from the morgue and putting them to work. Nevertheless, he remains optimistic now having created a superior spybot in Hachimaru and vows to create the ultimate android.
