"Esto es el fin," he paused. "El grande padre."
It was a phrase he had learned and said in order to show off his studies of Spanish, a language foreign to him.
As Gohan fought, he reached Super Sayan God Blue, fused with multiple Gohans of many timelines with potara and without, constantly refreshing and dancing again if the fusion took off, and as he lost, some of them reached advanced forms of Ultra Instinct- Gohan Blanco Rational, he called it, to show off his studies, as they seemed to be losing the fight, and he added them to his Super Sayan God, adding that on top of Mystic. Not to mention zenkai boost. And on top of it all, he was angry.
"Z-Zeno, erase him! Now!"
Gohan repelled Zeno's weak guards (were they weak or was he strong? He didn't know).
From behind, beings from his pocket universe that were consumed by the Happymajins absorbed Zeno, who was weak apart from his ability to erase universes and guards.
Soon, the Happymajins with Zeno's powers would create and not destroy other universes inhabited by the Happymajins, who in turn would create more timelines, up to infinity.
It was the end of Dragon Ball, the Grand Priest noted.
"You've achieved the perfect ending, Gohan." He nodded. They went forth towards maximal utility.
