With Dragon Ball Super fans abuzz with excitement in the wake of a massive announcement about the series' next major arc, many theories have emerged that have attempted to address Future Trunks and Black Goku, two characters that were specifically mentioned by series creator Akira Toriyama himself.

While Future Trunks' role in the upcoming arc is almost certainly straightforward, the identity and background of the arc's main antagonist, dubbed Black Goku, is still very much in question. Many theories have been pointed out, and many have been debunked. However, one particular speculation might very well be accurate.

When Toriyama revealed the details of the upcoming arc in his announcement, he mentioned that the chaos caused by Black Goku would be so prominent that the Gods of Destruction and even the Omni-King would have to be involved in a fight. Thus, if these extremely overpowered characters are to be involved, Black Goku must be a very valid threat.

Considering that the gods themselves would be involved in the fight, there is a very large possibility that Black Goku might not be human at all. In fact, many, in Future Trunks' timeline, Black Goku was even a God of Destruction.

This is actually pretty possible if Goku was resurrected in the future without his memories of his past life on Earth. Considering Goku's innate power and his background as a Saiyan, there might have been a series of events in the future which eventually culminated in Goku becoming a God of Destruction.

If this is indeed the case, then Toriyama's announcement could be explained pretty well. The gods would be involved in the fight because Black Goku is one of them. Indeed, if Black Goku is a God of Destruction who unfortunately went bad, he would definitely be a threat that is big enough to warrant a direct intervention from the strongest beings in the Universe.

Of course, these are but speculations. As creative and possible as these are, only the events of the anime's upcoming arc could really address these lingering questions appropriately. Until then, however, this particular theory is something to ponder on.
