"Dragon Ball Super" proves that blond hair is not necessary to match the exceedingly high power levels of Super Saiyan Goku, as Goku Black, who is Goku's evil counterpart, is bound to become more powerful in future episodes.
Episode 51 of "Dragon Ball Super" has teased a vengeful Goku Black, who has become even more powerful after suffering wounds from Goku back when they first met and fought. With this in mind, Goku Black seems to be out for Goku's blood and will stop at nothing to defeat him where he is now, convinced that his power level is the "true power of Goku."
This was shown in the preview of the upcoming episode 51 for "Dragon Ball Super," in which Goku Black is seen training hard for a rematch. Goku Black even trained with a future Trunks in his own timeline in order to match or surpass the strength of the original Goku — meaning, his dedication might eventually lead to one of Goku's biggest fights in the series.
It also seems that the more Goku Black studies and fights the real Goku, the more his power grows since Super Saiyans are known to become powerful after each battle, hence their never-ending training. All in all, Goku Black will prove to be one of the most formidable enemies of Goku and might even become one of the most difficult to defeat.
For those unfamiliar with who Goku Black is, he is the main antagonist of the Future Trunks saga for "Dragon Ball Super," as such, he constantly jumps timelines in order to improve his powers. While sharing the same physique and semblance as Goku, Goku Black is actually another person named Zamasu who stole the body of the original present Goku and sought to destroy all mortals including his future self.
Whether Goku can defeat Goku Black remains to be seen once "Dragon Ball Super" episode 51 airs next Saturday on Adult Swim during its Toonami block on Saturday evenings at 9:30 p.m EST.
