Black "What makes you think that you can take on the likes of me? You're nowhere near as powerful as Trunks is and I will make sure that you stay dead this time."

Black threw the first punch and YN blocked it, then he got him with a punch of his own, then kneed him in the stomach and kicked him back.

YN "You honestly think that I'm weak just because Trunks got stronger?"

Black "Come on Saiyan, show me what you got."

YN went to attack, when he was caught off guard by the speed that Black possessed and was blitzed by a barrage of punches, then was slammed into the ground as Black then charged up an attack and threw it at YN. YN put his hands out and went to catch the attack, but something else happened. Something rather strange. YN's palm in his prosthetic arm opened up and absorbed the attack, giving YN the energy that he needed to keep fighting.

YN "Bulma, you really had some tricks up your sleeve when you made this didn't you?"

Black "Ah, you might not be a waste of time after all, I needed someone to test this body on."

YN "This body? What are you talking about?"

Black "The answer to that is something that you don't need to know."

He then flew at YN and started throwing haymakers at him. He then fired a bunch of ki at YN as he was flying around trying to dodge them all, but Black then appears in front of YN and kicks him in the chest sending him to the ground. YN coughs up a bit of spit mixed with blood. He falls back further into the ground as Black just fires a barrage of ki blasts at him and is laughing as he does so. Out of the smoke YN comes flying out and the two continue to trade blows. Black gets back and says.

Black "Kamehameha!"

YN does the same thing and fires his own and the two manage to meet in the middle with their blasts and black starts pushing YN's blast back, causing YN to struggle holding the beam up until YN Transforms into a Super Saiyan 2 and the energy that YN absorbed from Blacks attack earlier gave him enough energy to send it back and YN won the Beam struggle. When the dust cleared, YN saw Black fly into a building, but something comes from Blacks ring and then a portal opens up in the sky. Black gets up and flies towards YN and he then notices the portal.

Black "Strange. So that's where you are Trunks."

He starts laughing again and goes into the portal, YN flies into it and yells.

YN "You're not getting away from me!"

YN chased after him and when they got through the portal YN punched Black in the face sending him flying through the air. YN then noticed the change in the sky. It was bright, sunny and there were actually creatures running and flying around.

YN "Am I in the past? Wait, if I'm in the past then that means.'

YN looked down and saw his dad, Piccolo, Vegeta, Krillin, Trunks and Bulma. Then he was blitzed and Black had put a ball of ki into YN's stomach and sent him into the side of Capsule Corp. Leaving a big dent in the building. YN goes to get up when he gets knocked out cold. Trunks rushes over to him and carries him to Bulma and the others.

Bulma "Who is that? His Gi reminds me of Goku's, just not with those sleeves."

Trunks "If I had to guess, this is YN, the older brother to Gohan."

Bulma "Wait, I thought that Chi-Chi miscarried YN."

Trunks "In my timeline, he was born and he risked his life to save some survivors when the Androids attacked and from the looks of it, lost his arm and was put into a coma."

Bulma "I've gotta let Chi-Chi know about this."

Author "Looks like we've ran out of time for this Chapter, what will Chi-Chi say? Will she be happy to see her son? Find out next time on Dragon Ball Super."
