We both fly into the air and head towards an island which has no life on it.

YN "Perfect place."

Goku "Man, I wanna know how strong you've gotten YN."

YN "And the same goes for me, I want to know how strong you've gotten."

Goku "Hehe. Come on YN, let's do this."

Goku gets into his fighting position so I do the same and it feels like an eternity has passed but then a rock falls and we charge forward at each other trying to hit one another but we keep dodging each other's attacks. Then I hit him in the stomach and it sends him back a bit, I then charge at him again and kept on hitting him, he goes to hit me in the face and I duck under his punch, then I hit him into the air.

YN "HAAAAAAAAAAAAAAAAAAA!!"

I fired ki blasts at him left and right causing a big cloud of smoke to appear where goku is at.

Goku "Tch HAAAAAAAAAAAAAAAAAAA!!!!!"

A gold light appears from the cloud and reveals my brother as a super saiyan, he went to hit me but I blocked it and realized that his attacks were a lot harder than before.

YN "You're a super saiyan?"

Goku "Yeah I got it a long time ago. Wait, how do you know about super saiyan?"

YN "*Chuckle* Simple."

I clenched my fists and powered up.

YN "HAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!!!!!!!! HHHHHHYYYYYYYYYAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHH!!!"

I transformed into a super saiyan as well.

YN "I've been able to transform for quite some time now."

We charge at each other and we try to overpower each other. We both let out a scream and cause an explosion in the air.

Piccolo's Pov

I'm training Gohan to be able to unleash his potential, when we feel a sudden increase in power coming from the west.

Piccolo "What the hell?"

Gohan "It's dads energy, but who is he fighting?"

Piccolo's mind "He isn't fighting Vegeta because we wouldn't be able to sense their energy, wait it couldn't be him could it?"

Piccolo "Let's go Gohan."

Gohan "Okay."

We took off to find out who the source of the energy belongs to.

YN's Pov

YN "Is this all you got Goku? I was expecting more. HYYAAAAAA!!!!!!"

I hit him into the water and went after him but he wasn't in there anymore so I looked above me and saw a blue beam coming at me and put my hands in front of me to stop it.

YN "I was wrong brother, you have gotten stronger than before, but let me say one thing."

I fired my own kamehameha at him. It sent his back a bit but his kept coming closer to so I decided that I had enough.

YN "Okay then super saiyan 2 it is then, HAAAAAAAAAAA!!!!!"

I powered up and the beams were in the middle then they just stopped causing the both of us to fall back and charge forward once more.

Whis' Pov

Lord Beerus and I are sitting back and relaxing while eating some delicious food. When we see explosions.

Beerus "Whis what is causing these explosions?"

Whis "Hmm, it seems that goku is fighting someone that looks just like him."

Beerus "You mean to tell me that Goku has a twin brother?"

Bulma "I could have told you that."

Beerus "You mean to tell me that you knew he had a twin?"

Vegeta "This world doesn't need another Kakarot running around, one is just enough."

Whis "He could be one of your team mates for the tournament of power."

Vegeta "Tch."

YN's Pov

We keep colliding fists and he decides that he's had enough.

Goku "Okay we don't have time, so I need to end this fight fast. HAAAAAAAAAAAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!!!"

His hair turned blue as did his eyes and I couldn't sense his ki at all.

YN "W-what is that form?"

Goku "It's called Super Saiyan God Super Saiyan or Super saiyan blue for short."

YN "I guess I should transform as well. HAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!!!!!!!!!!!!!"

Goku "What is that roar?"

YN "HAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

I transformed into super saiyan 4.

Goku "What form is that?"

YN "It's called super saiyan 4, a transformation that is only accessible to those who have their tail."

I go to attack goku and he catches my fist and proceeds to beat the crap out of me. I go to stand up and he kicks me in the face sending me to flying through the air. I can hear my wife screaming my name. I fall to a knee on a different Island and came up with a plan. With all of my strength, I got to my feet and placed little things of ki everywhere and when he went to go to me an explosion went off causing Goku to fly into the air and think.

Goku "What was that?"

YN "A little trick that I taught myself."

He turns around to be met with a kick to the chest and a kick to the stomach. I then hit him into the Island, but he appeared behind me and hit me with the Kamehameha sending me down.

YN "AAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHH!!!!!"

After firing the Kamehameha, Goku flew down and saw that I was struggling to get to my feet.

Goku "This fight is over."

YN "Tch, this fight isn't over yet goku."

He turns around and that was the last thing I remember before blacking out. Whe I woke up Goku was on the ground struggling to move and I was next to him on a knee.

YN "What happened?"

??? "Allow me to explain."
