Xeno Goku and Xeno Vegeta may have unleashed an amazing amount of power to stop Cumber from wasting normal Goku but it seems that Fu's prison planet experiment has yet to be fully defeated. But with Ultra Instinct Goku being the hot topic for “Dragon Ball Heroes” episode 6, fans may be wondering if this is the highest power evel that can hopefully defeat the seemingly unbeatable Cumber.
Fans will remember that the Ultra Instinct technique is so advanced that even gods have difficulty mastering it. Goku may have already completed the training to utilize both the defensive and offensive properties of Ultra Instinct but he can hardly be called a master of the extremely difficult technique. Allowing the user to fully react to any threat without thought while still able to go on the offensive, Ultra Instinct does sound like the perfect counter to Cumber's ever-increasing power in “Dragon Ball Heroes” episode 6.
Unfortunately, Ultra Instinct has one drawback that may be of concern for fans of Goku if he really is taking things to the next level in “Dragon Ball Heroes” episode 6. The technique can only be used for short amounts of time, eventually burning out its users, which could sometimes even lead to death. If Goku is really going to pull out Ultra Instinct against Cumber in “Dragon Ball Heroes” episode 6, he might have only a short window to make sure Cumber no longer gets back on his feet before succumbing to the negative effects of his own technique.
The crazy power levels promised by the Ultra Instinct technique, as well as the sheer amount of uber-powered forms already thrown at Cumber in the show's previous episodes, are enough to make sure that fans can expect “Dragon Ball Heroes” episode 6 to be where Cumber falls. As user Rui Silva points out on Quora, if the Goku in “Dragon Ball Heroes” episode 6 turns out to be a master of the Ultra Instinct technique, there is a pretty high ceiling for what fans can expect from the Saiyan.
Fans looking forward to seeing how exactly Goku will take out Cumber with the Ultra Instinct technique can watch the Carddass webpage for “Dragon Ball Heroes” episode 6 updates. Hopefully, news of the next promo episode's broadcast date will be announced soon.
