Goku and Azmuth teleported to Earth's plumber base, with Ben approaching them as they arrived. Azmuth confidently replied that he had come to make important changes to the Omnitrix and give Ben some new, powerful alien DNA. When Ben asked why the Omnitrix didn't scan Goku's DNA and showed new DNA presence twice, Azmuth was straightforward in his response. He explained that when Goku was not on his guard, the Omnitrix scanned him as a new alien. However, when Goku increased his ki or energy, it detected him as a type of anodite mutation due to the resemblance, which the Omnitrix was not built to scan.
After finishing the adjustments, Ben asked Azmuth about the update in Omnitrix, and he responded confidently that it could now scan mutated versions, but he had made it manual, so Ben had to actively do it. He also gave Ben a new alien - Saiyan DNA, a powerful addition to his arsenal. As Ben transformed into the Saiyan, Rook commented on his new transformation, saying that he looked completely buff and jacked, getting years of gym results in an instant.
Despite Ben's excitement, he was unable to use ki blast and fly, and he asked Azmuth why he couldn't do it like Goku. Azmuth confidently explained that Goku did those things with the help of ki, so Ben had to learn it from him. The version Azmuth gave Ben was a bit toned down in comparison to Goku's version. When Ben asked what he could do for now, Azmuth told him to train with Goku for a few days and take care of him while he went back to his work.
As Azmuth handed Goku a container and asked him to fill it with his ki, he teleported to GALVAN PRIME, leaving Goku and Ben alone. Goku smiled at Ben and said, "So take care of me for a few days." Ben was eager to learn and said, "First teach me all the stuff." Goku confidently replied, "Fine, lead me to somewhere open and let me adjust my power level." Ben, excited to learn from the powerful Goku, took him to an isolated mountain range, and Goku adjusted his power level to Krillin level.
After reaching the mountain range, Ben transformed into the Saiyan, and Goku confidently told him to punch him. Ben obeyed, and Goku pushed him back a few steps. When Ben asked why he felt a bit weak, Goku confidently explained that with ki control, one could make oneself strong or weak depending on their capabilities. It looked like Ben's strength was similar to Goku's son, which brought back some memories for him. Ben replied with a smile, "Dude, I already have a father, no need for a second," and launched at Goku. Goku confidently stopped Ben's punch and replied, "I don't have any wish to become your father, and right now, I am your teacher." After this, they sparred until Omnitrix time ran out. When Ben was in his human form, Goku confidently taught him about how to feel ki and its application. Both trained until evening, and Rook watched them. He thought that while Ben looked two times more powerful during the fight, Goku's skill was enough to dodge, counterattack, and dominate Ben.
After training, all of them went to the plumber headquarters, and Ben confidently ordered a lot of food for Goku and fries for himself. Before dining, Goku confidently washed himself, and Ben confidently invited him to play a video game round. Goku was clueless about the game, but Ben confidently explained the basic controls, after a few rounds, Goku started to get flustered because Ben dominated him in video games. Goku ended up destroying the remote controller accidentally, and Ben confidently asked him why he broke it if he couldn't win. Goku confidently replied that he pushed the buttons a bit too hard and fixed the controller with his matter manipulation.
The next day, they confidently continued their training routine, and Ben sometimes went to save the city. Because of his training, Ben's coordination with his alien power became better. At night, they confidently played video games together, and Goku confidently started to mimic Ben's movements and secured some wins.
After three days of Goku's arrival on Earth, Professor Paradox confidently came and asked if Goku was ready for the next session. Goku confidently replied with a resounding "Absolutely!" and left with Professor Paradox. Within three days, Goku had confidently taught Ben about ki control and Super Saiyan 2, as well as ways to obtain God ki.
