Son Goku vs. Son Goku

is the twentieth and final chapter of the Super Dragon Ball Heroes: Ultra God Mission!!!! manga.
==Summary==
Starting with Super Saiyan, Xeno Goku and Goku exchange a series of powerful attacks. Goku dodges Xeno Goku's first kick and blocks his second, then attempts a Double Axe Handle that Xeno Goku quickly evades. After another clash, their fists connect as they turn Super Saiyan 2 and up the ante. Xeno Goku manages to kick Goku away as they both ascend to Super Saiyan 3 and fire a True Kamehameha. Finally, they decide to start the evolutionary split - Xeno Goku using Super Saiyan 4 and Goku using both Super Saiyan God and then Super Saiyan Blue once the Kamehamehas detonate. 
Super Saiyan Blue Goku lands a clean kick on Super Saiyan 4 Xeno Goku, though he is repaid with a powerful uppercut from the Time Patroller. Once again, the two engage in a fierce fistfight before ascending again. Super Full Power Saiyan 4 Limit Breaker Xeno Goku stares down Ultra Instinct Sign Goku, the former declaring that he is at his current limit while the latter declares for them both to give it their all. As a Full Power 10x Kamehameha collides with an Ultimate Instinct Kamehameha, a colossal explosion of ki engulfs the arena.
Meanwhile, Aeos and her Warriors in Black are seen travelling through space and while most the group converse, Aeos notices that Xeno Bardock appears quiet. She asks him if he is ok with not seeing the battle between his two sons but he simply responds by saying he has already seen enough. 
The heavy energy output leaves Xeno Goku panting, though once he catches his breath and the smoke clears, he is surprised to see that his prime counterpart had one more transformation up his sleeve - the complete Ultra Instinct. Smirking, Xeno Goku charges his other self with an extreme-speed left punch, but with his newfound instinct, Goku swerves around it and decks him with a right hook. Unable to handle his counterpart's final blow, Xeno Goku reverts to base form and collapses with a smile on his face, recognizing his loss. The victorious Goku reverts and collapses as well, equally exhausted. Xeno Goku praises Perfected Ultra Instinct's strength, though Goku admits he doesn't quite have full control over it and that he still has room to improve, to which Xeno Goku agrees. 
Xeno Goku then receives a transmission from Chronoa, who had been waiting for the fight to finish alongside Piccolo, Gohan, Vegeta and Xeno Trunks so she could send Goku and co. back to the main timeline. She thanks everyone for helping her protect history, though both Gokus say it's no trouble, since they got to brawl with the mightiest around.
