'Dragon Ball Super' Episode 53 spoilers news: Kaioshin apprentice from Universe 10 linked to Black Goku?

The upcoming episode of "Dragon Ball Super" is expected to answer the biggest question so far in Akira Toriyama's massive anime hit series: Who is Black Goku, and why does he intend to destroy all humans in the universe?
The Episode 53 of "Dragon Ball Super" is titled "Reveal Black's True Identity! Now, to the Kaioshin Realm of Universe 10!" which will focus on the quest of Son Goku, Beerus and Whis to discover the persona behind Black Goku, the newest and perhaps the greatest menace in the universe so far. It appears that the Universe 7's God of Destruction and his companion have an idea regarding Black Goku's real identity, and their quest for knowing the dark truth will lead them to Universe 10, where they will meet a new interesting character. It is yet to discovered, however, if this new addition to "Dragon Ball Super" will be someone to like or be despised like Black Goku.
As reported by Movie News Guide, the previous episode of "Dragon Ball Super" featured Son Goku facing the Universe 10 Kaioshin apprentice named Zamasu. Beerus and Whis earlier noticed the mysterious dark aura surrounding Black Goku when he first appeared in front of the Z fighters in the present timeline. They said that Black Goku's aura is something very familiar to them, and this mystery eventually caused them to travel to the distant Universe 10 and confront the Kaioshin that possesses the same aura as Black Goku, which is none other than Zamasu himself.
The later part of the episode showed Goku in his Super Saiyan form fighting Zamasu. At first, it appears that both are at par in terms of strength, power level and battle skill, but later on it became evident that Zamasu is the more superior warrior. The next episode is expected to continue this clash as the secret of Black Goku will slowly be unraveled. The same disdain against humanity shared by Zamasu and Black Goku would eventually be explored in Episode 53, confirming whatever connections these two characters have.
The official episode synopsis for Episode 53 as quoted by Yibada reads, "After realizing that Black has the same ki as Zamasu, Universe 10's apprentice Kaioshin, the God of Destruction Beerus and his attendant Whis head to Universe 10 together with Goku. In order to verify his ki, Goku challenges Zamasu (who distrusts humanity) to a battle, but..."
