Planning to eliminate all members of the Yakuza faction, Clint Barton began to fight against them, despite their great numbers and rapid gunfire. Barton managed to make his way through all enemies with great ease, going through a building where he headed for Akihiko, a Yakuza operative. The two then found themselves in the streets, where Akihiko questioned Barton on his actions, which he informed him that they survived the Decimation and half the population didn't.
As their the duel began settle down, Barton was able to cut Akihiko twice, causing him to beg for his life, and promising to give Barton anything he wanted. However, Barton ignored Akihiko's cries for mercy, stating that the only thing he wanted, which was his family, could not be given by him. Barton then finished off Akihiko, cleaned his sword, as he became aware of Natasha Romanoff standing behind him, telling her that she shouldn't be there.
Romanoff noted that Barton's violent actions could not either, but he informed her that it was all a part of a job that he believed he had to do. Romanoff addressed how everyone Barton has murdered was not going to bring his family back, for which she then informed him a plan to bring everyone back. However, despite desperately wanting to be with his family, Barton initially rejected the idea, not wanting to be given hope, only for it to be taken away if he failed.
Noticing her friend in distraught of what he had endured and what he had become, Romanoff apologized to Barton for not giving him hope sooner than later. Romanoff then comforted him by holding his hand. The two then entered the Quinjet and flew back to the New Avengers Facility.
With Scott Lang giving the idea to use the Quantum Realm to travel back in time, the Avengers began to work on a way to successfully do so. Barton watched as Lang prepared to test the time traveling, to see if it actually worked. Noticing they need a new subject to send back into the past, Barton volunteered and was equipped with an Advanced Tech Suit before transported through time in the Quantum Realm. When Barton returned from the past, he was temporarily discomforted by the travel, but quickly adjusted, as Romanoff went to check on him and see if he was fine, he told her he was and informed the Avengers that their plan had worked.
