Grand Zeno is basically the god of the Dragon Ball universe. He makes even the gods of Destruction tremble with fear. He has the power to wipe out anyone except maybe the angels from existence with a simple motion from his hand.

Despite his ultimate divinity, Zeno is like a child. He makes good friends with Goku.

Goku finds his future counterpart during the fight with Goku Black. Future Zeno manages to erase Zamasu from existence.

To the horror of Lord Beerus, Goku brings the Future Zeno to the current timeline.

And Goku introduces Future Zeno with the current one. Both gods become friends with each other.

And both watch gleefully during the tournament of power. They both also happily erase the losers from existence.

And to no surprise, they’re both happy Goku’s team won.
