"Son Goku Arrives" (孫悟空到着 Son Gokū tōchaku) is the 58th chapter of the Dragon Ball Super manga.
The fusion of Miza, Iwaza and Kikaza defuses after being defeated with a single punch by the newly-arrived Goku. After telling Krillin that he believes he may now be able to defeat Moro, Krillin asks if he is worried, but Goku simply tells him that he is actually just super excited. Goku teleports to Tien Shinhan, Yamcha and Chiaotzu - who are losing their battle with Zauyogi - and proceeds to take down their foe in an instant. As Zauyogi is taken away, Yamcha informs Goku that Gohan and the others need him, and so Goku teleport away once more.
The battle with the empowered Saganbo is going poorly, with only Gohan and Piccolo still fighting the brute - as Android 17, Android 18 and Jaco have retreated to the sidelines. Gohan and Piccolo fire a powerful blast in unison directly at Saganbo, but he is unharmed and merely batters them away. Jaco questions Saganbo as to why he would work for Moro, with the former convict explaining that it was because Moro saved the prisoners from the Galactic Prison and gave them power that will make sure that they will never get captured again. Suddenly, Saganbo is attacked by Goku - moving too fast for anyone but Jaco and Moro to see - and is sent flying towards Moro, who knocks him aside. At Moro's request, Goku reveals himself and Moro notes that he has grown much stronger than he was before.
However, Saganbo gets back up - having been powered up by Moro when he knocked him aside. Goku tells him to return to the Galactic Prison now that all his comrades had been recaptured, but he refuses. Gohan apologises to Goku for being unable to defend the Earth from Moro, but Goku praises him for the newfound strength he and Piccolo have gained over the past two months, saying that he hardly recognised him. Goku engages Saganbo as a Super Saiyan Blue and overwhelms him. Believing the fight to be over, he prepares to battle Moro, only for Saganbo to stand up again, stronger still after receiving another power-up from Moro.
Goku demands that Moro stop powering up Saganbo, who is clearly on his last legs, but Moro refuses, saying that he wants to see the ability Goku was using when he first arrived on the battlefield. As Goku attacks Moro to try and stop him, Saganbo suddenly collapses and dies - Moro's energy was too much for his body to handle. Moro nonchalantly brushes off Saganbo's demise, regarding him as an expendable pawn in his plans. Angered by Saganbo's needless death, Goku vows that he will kill Moro for what he's done and unveils his new ability - Ultra Instinct Sign - which a shocked Moro recognizes as a technique of the gods.
