Zeno aka the Omni-King was introduced during the tournament between Universe 6 and Universe 7 as the most powerful being in existence. As stated in a report from Atack of the Fanboy, Goku will finally get to meet and talk to Zeno in "Dragon Ball Super" episode 55, right before Goku has to travel through time and fight Goku Black.
According to the report, the offiical title of episode 55 roughly translates to "I want to see Son Goku. A request from Zeno," indicating that Goku will be brought for a special meeting with the most powerful being in all of the 12 universes. Yibada points out that this could mean Goku and Zeno will begin planning a brand new inter-universe tournament.
It is highly speculated that a new tournament is going to be held and this will allow Zeno to witness the true power of Son Goku. Fans suggest that this means Goku may one day be chosen to train directly under Zeno once Goku has surpassed the level of power that Beerus and Whis have right now although this has yet to be confirmed.
However, the title for episodes 56 and 57 suggest that this meeting does not last for very long. Episode 56 indicates that Goku and Goku Black will have a rematch and that during this fight Goku Black will unleash a new form, called "Super Saiyan Rose" in which Goku Black has pink hair. This may be his equivalent of Super Saiyan Blue.
Episode 57's title indicates that throughout the battle Goku may have been holding back but will now unleash his true power as a Super Saiyan Blue, hinting that the fight might end here with Goku officially beating Goku Black unless something or someone interferes. It is possible they will be interrupted, giving Future Trunks the opportunity to deal with Goku Black.
"Dragon Ball Super" episode 55 airs this Aug. 14.
