Piccolo and Kakashi Hatake returned to the warehouse studio that belonged to the television show that they presented. Actually it belonged to the producer, a man who was pleased to see the two warriors once again. Like how procedures had been done before, the presenters stood in front of the cameras and began to speak.
"Welcome, all. My Namekian friend and I would like to greet you to this brand new episode of Piccolo and Kakashi on Theories," the white haired ninja started. "We're staying in the Dragon Ball franchise for this one, but we're talking about the most recent series, Dragon Ball Super. More specifically, the current story arc. If you have not been watching Super yet or for whatever reason you don't want to be spoiled, please skip this episode."
Mirroring previous episode, a silence followed.
"Then let's begin," Piccolo continued. "In the Future Trunks saga of Dragon Ball Super, which is currently airing at the time of this episode's recording, there are two villains: Black Goku or Goku Black and Zamasu. As of now, there is a lot of mystery surrounding these two. It was believed that they are the same, but that theory has been disproved by the show itself. We have been wondering exactly who or what they are and what their relation is."
"In the preview for episode 58, we can see that Zamasu eventually gets his hands on the Super Dragon Balls. Likely, he gains his immortality through them. But where does Black Goku come from? If Zamasu does wish for immortality, then that leaves very little room for Black Goku's birth though Zamasu probably finds a way to create him later on. Black could also be created through the Super Dragon Balls and immortality would come later," Kakashi added.
"If Zamasu wishes for Black Goku's creation, he could potentially fuse with Gowasu or somebody else to gain immortality. Similar to how the Old Kai gained magical powers after fusing with a witch. Speaking of fusion, Black Goku wears a Potara earring, as does Zamasu. It is possible that Potara fusion is a back-up plan of theirs should the 'humans' become powerful enough to stop them and the earrings were most likely taken from Gowasu."
Kakashi nodded. "We could be wrong, but that is what we believe their backstory is and what they will do later on. We'll just see what happens in the future."
"Thank you for watching," Piccolo finished, ending the episode.
