The moment Dragon Ball fans have been waiting for is finally here: Goku vs. Goku.

Ever since teaser posters revealed what appeared to be an evil Goku from an alternate future, anticipation for an all-out battle between the villain and the kindhearted Goku fans know and love has been building. First, the villain, referred to as Black Goku, appeared in the future, destroying much of the Earth and nearly killing Future Trunks.

Trunks travels to the past to warn his friends of the coming threat. That threat has now arrived in episode 50 of Dragon Ball Super, and the result is a battle unlike anything fans of the series have seen before. Goku, being the defender of Earth that he is, steps up to take the fight to his evil doppleganger, but Black Goku is far more powerful than he appears. Even though Goku only goes Super Saiyan and the two are merely gauging one another's power levels, Black Goku is more than capable of going toe-to-toe with him in their first fight. That doesn't bode well for Goku and friends.

Sure, Goku has yet to enter his most powerful forms. Recent storylines have shown Goku to be more powerful than ever before, even being able to use his old kaio-ken technique while in his super-power Super Saiyan Blue form.

If, however, Black Goku is half as strong as a Super Saiyan Blue-level Goku, the Z fighters may have their work cut out for them. Goku is by far one of the most powerful beings in the universe, so having an evil version of him that is potentially just as strong is just about the worst case scenario for the Earth. 

Plenty of questions still remain. What exactly does Black Goku want? What happened to turn this future Goku evil? What's up with that one green earring that Black Goku wears? Why is his name the super-awkward Black Goku (aside from him wearing black clothing and obviously being super evil)? That's still unknown, but no doubt, plenty of answers to those questions will be revealed in time. This is Dragon Ball we are talking about, after all. This fight between Goku and Black Goku will likely go on for several more episodes, so there's plenty of time for Goku to use his full power and get some answers. In the meantime, fans can enjoy this clip of the duo's first battle.
