Somewhere in the Mountains:

???: I will kill you Son-Goku!

???:As will I have my prize of Son-Gokin~

In Kouh, Gokin POV: 

I was just relaxing after we killed Frieza, we all did, it was fierce. I was lost in thought about how I could become the legend of my race, a Super Saiyan. "Guess it has to be with me being 'special' as shenron put it." I said but no-one heard. Rias was lecturing Issei about something stupid, if it's Issei I only pay attention if it has something to do with anything BUT perverted. It entertains me because he gets the crap beat out of him by a GIRL!! Anyway, I'm just happy we all returned back safe. 

"Hey Gokin, what was that red blast, it looked like the Kamehameha but Crimson? Oh! And why did you go blonde?" Rias asked with curiosity in her voice. All I could say is, "I think I made a new technique, Crimson Kamehameha. I used your ki and I can use little destruction energy now, I'm a Gremory. And the 'Blonde' thing. It's a legend of my race called Super Saiyan, it multiplies our strength speed and senses by 50." So, as usual, they asked me to do it. I realized that it takes a burst of anger to release it. I just had to put Rias in Issei's place and... "AHHHHHHHHH!!!!" A golden aura burst forth from the heavens and my eyes go teal and my hair golden, I was far past goku at this point, even Goku and Vegeta Combined in strength from being a devil so the super saiyan transformation took it to a new level. As if on que, a blast hit were I was and I fell unconscious. 

Rias POV:

The dust settled and I saw Gokin, lying unconscious on the ground. I rushed and gave him a senzu bean. He sprang up and turned to see his attacked, a weird bug thing that looks like a avacado has sex with an older more disgusting avacado. "The names cell, and this is android 21." A beautiful busty girl walks up and she looks like a scientist and a fighter. She had long brown hair blue eyes and glasses. I looked at Gokin who was just waiting for one of them to make a move while Issei, my 2nd most powerful piece, is drouling and is bleeding out of his noses. Koneko just kicked him in the gut and he fell hard to the ground. 

Gokin POV: 

'What do they want with me,m and my friends?' I thought. I got into my fighting stance which is a combination of goku and vegeta's I had the 2 fingers up front like goku but had the claw in the back like vegeta. Cell made his move, he shot a Galik gun at Rias, she put up a magic barrier but it barely held, I powered up to my limit and formed a Crimson Kamehameha. "CRIMSON! KA.....ME.....HA.....ME.....HAAAAAAA!!!!!!!!" I shot forth the beautiful crimson ray towards them, 21 disentagrated, along with anything the blast touched, I did have the destruction power of Rias after all. Cell just dodged but he got hit, he tried to absorb Kiba but Issei jumped in his way. Issei...is...gone. "BASTURD! SUPER KAIO-KEN!!!!!!" My hair and aura got a reddish tint to it as my strength, speed, and senses were 100x my base form. I rushed cell, I sent a barrage of punches so fast, not even Kiba couldn't see them. Cell just dodged easily. -BOOST- cels arm turned red and he changed into semi-perfect cell. He then left and I fell to the ground exhausted. 

TIMESKIP

It's been 3 days since Cell attacked, he absorbed Yamaha, though, no one cared. 🖕🏻YAMCHA! Anyway, I told goku and vegeta and now, we are all on par with each other. We also, have a new secret weapon for the upcoming cell games.
