The saiyan experiment

Fusion of hope

"are you all right?" someone said as my vision cleared and i was staring at a copy of vegito black but the hair was blue with a blue gi and an orange inner shirt wearing white gloves and boots. "before you ask we are vegito blue!" he said his aura flaring up before in a flash of blue and pink light they shot off battling at speeds surpassing even ultra instinct as the supreme kai and trunks landed next to me. each blow shook the fabric of this dimension as they moved around and unable to follow i sat down staring at my hands. closing my eyes i focused with my energy managing to see bits and pieces of the battle. they both seemed unreal moving with precise strikes each with the force to nearly sweep all from the area and it seemed like both had yet to use their full power when they shot out of my sight making me grunt in frustration as i opened my eyes and stood up feeling reality unable to handle their power as the air seemed to ripple and yelling i raised my power until i couldnt and activating fury mode i closed my eyes seeing a little more of the battle. blocking several kicks vegito drove a fist into vegito blacks gut before getting knocked back by a swift chop to the neck before they broke into an all out brawl of punches and kicks both fighting so hard that the upper body of their gi,s exploded into nothing as they locked hands and raised their power to new heights before getting out of my view once again as i reverted my fists clenched. "somethings wrong" trunks said and i looked at him with a raised eyebrow. "father and goku are his equal but why is vegito black holding back so much? he shouldnt be having this much trouble with him since both are equal but it seems that our vegito is holding the upper hand no matter what.wait! supreme kai is their any weakness to the potara fusion!" he said his voice growing urgent as the kai paled. "ive heard a rumor that a potara fusion in another universe forced the fusion to end from sheer power many years ago but i never had the idea to wonder if it was true!" he said as i felt dread grip me. "hes waiting for their fusion to end before he goes all out!" i said before getting ready to fly towards them needing to warn them. "hold on i have an idea! on earth when majin buu came goku taught a technique to goten and trunks that allowed them to fuse. its only half the time for potara but its just as powerful!" he said as trunks and i smiled. "alright show us!" i said and what followed was the most ridiculous dancing ive ever seen. "do i really have to do that to fuse?" i asked as the kai nodded making me sigh before looking at trunks. "alright lets do it!" i said as he nodded and doing that stupid dance we were engulfed in a giant light. looking at my body i had a black vest with orange fringes a black shirt underneath with white baggy pants and black martial arts shoes. my hair standing up like a super Saiyans with a black middle with blue hair on the sides and a sword was strapped to my back. "we are trego" i said before noticing vegito stop in the air before defusing. shooting forward i grabbed goku and vegeta before appearing where i had been setting them both down i turned to look at vegito black as he reverted landing on a platform opposite of me. "you believe a mortal made fusion can defeat the divine potara?" he said as i smirked. powering up i transformed into super saiyan blue as he went rose and slamming our fists together at full power the familiar cracks formed around everyone as we appeared back in trunks timeline. dodging several attacks i then kicked vegito black in the face before raising my palm to his midsection. firing a ki beam it sent him flying back several miles before exploding the force felt throughout the universe as i was met with a spinning disc of ki cutting my cheek as i dodged it before i ducked as vegito black appeared behind me his foot clipping my hair and flipping i kicked him in the stomach with enough force to make him vomit as i landed on the ground and cupping my hands i focused forming a sphere of pulsing blue fire. "burning kamehameha!" i roared unleashing the beam as vegito black formed a barrier blocking the attack but before my attack ended i appeared above them and drawing the sword from my back i infused my energy within the blade turning it a golden color. stabbing the sphere it shattered as vegito black tried to counter with an energy blade but shattering it the energy on the blade turned blue with an intense aura as i made it grow in size as vegito black stared in fear. "this is for all the people youve killed! i roared stabbing him in the stomach making him cough blood as he grabbed the blade. pulling it free i watched him revert as i slashed at incredible speeds cutting him to pieces in an instant before raising my free hand. "This is the power of mortals! now burn in hell!" i cried firing a point-blank beam of gold and blue energy with my full power engulfing vegito black who screamed in rage. "i wont be killed by a pathetic and corrupt mortal!" he screamed but activating my fury mode i increased my power even more turning the energy beam white as i watched vegito black turn to ash and soon even that was obliterated as i defused trunks and i both falling towards the ground. suddenly both of us were caught and sat down by goku and vegeta as i looked at goku. "We still have to stop our zamasu" i said as vegeta smirked. "beerus took care of him so there is nothing to worry about rego" he said with unusual kindness as my vision went black.
