The saiyan experiment

the end of goku?

dodging my initial attack jiren's fist shot out nicking my side and making me slide back but jumping at me jiren then landed a kick to my stomach launching me back but catching my leg he threw me into the air followed by another giant ki blast. dodging with another ki blast i was suddenly sent crashing down by a knee to my back from jiren and as i met the ground i forced myself to revert to conserve stamina. standing back up i noticed jiren already walking down towards me. "this fight is over" he said the pressure from his ki weighing heavily on my body. "now vegeta!" goku yelled and appearing in front of me as super saiyan blues they fired a combined ki blast sending jiren flying up. "rego youve done enough nobody is mad about before you dont have to shoulder this burden on your own" goku said making me tear up but wiping it away i stood up powering up my base form. "me and vegeta will handle it you go rest" goku said as vegeta grunted both rushing jiren who had landed across the ring and meeting him head on they attacked at once their off-key attacks actually seeming to throw jiren off as he began taking minimal damage. suddenly jiren landed a punch sending vegeta flying as he kicked goku into the air but taking the opening i launched myself at him my fist driving into his arm as he blocked me. grabbing my arm he slammed me against rubble sending me straight through to the other side and sprawling across the ground i slowly got up. "damn i have to help them" i muttered before i blocked a punch to my face. shoving the stranger back it was a large bird man with an evil look in his eye. "finally i can take you down!" he said punching at me but blocking his fist i slid back as he fired a ki blast but kicking it up i was caught off guard as a fist appeared inches from my face. leaning far back it went past me and kicking him in the chest he stumbled back. smirking he straightened up before changing his stance. as i watched i sensed his power beginning to rise from our small skirmish and he was leaving less openings. "so your like a saiyan" i said making him look at me confused. "huh?" he said as i smirked. "your able to rapidly improve in the midst of battle but unfortunate for you i know how to counter that ability" i said making him scoff at me. "oh yeah how?" he said mockingly as i focused and with more effort than i liked i transformed into a super saiyan. "i have to beat you before you can even start to improve!" i yelled rushing forward and landing a solid punch to his face before kicking him back. across the battlefield, goku had utilized kaioken times 20 from what i could sense and vegeta was tapping into a hidden power far greater than even my incomplete ultra instinct. "damn im falling behind already" i said with a smile. refocusing on my opponent i jumped forward as he came at me and punching his arms he managed to hold his ground his power rising. "having trouble old man?" he said with a grin but gritting my teeth i kicked him in his side making him grunt in pain and lower his guard which i exploited uppercutting him into the air. jumping up to him i powered up even more as i grabbed his leg and threw him back to the ground. landing i rushed at him as he fired a beam but leaping over it i slugged him in the face again then drove my knee into his chest before launching him back with a shockwave from my hand. "damn hes improving again!" i said as his power shot up near my level. "your all talk old man im going to crush you!" he said as he walked towards me. "damn i wanted to gather more ki from our fight but at this rate i have no choice!" i said slowly powering up until in an explosion of power i transformed into a super saiyan 2. "get ready!" i said harshly before launching myself at him. blocking the panicked punch he threw at me i kicked him in the stomach once making him hunch over before i spun once kicking him in the face with the same leg making him lurch to the side. "damn not enough" i muttered as i felt his power go to increase. screaming i punched him in the face as i transformed into a super saiyan 3 the force cracking his beak. "you were pretty good" i said before kicking him away and following i punched him several times in the chest and stomach before delivering a crippling elbow strike into his stomach knocking the wind out of him. "thanks to you i found power i didnt know i had" i told him before winding up for a punch. with desperation in his eyes he pulled back and punched at me but catching it with my free hand i easily moved his fist to the side before calmly slamming my other fist into his face sending him flying out into the void. looking around i realized i had been so absorbed in my fight with jiren earlier some universes had already been erased and krillin, master roshi, and piccolo had all been knocked from the ring. "hey you" a voice said and turning i reverted as i saw celera walking towards me. "oh crap" i muttered as she grew closer. holding her hand up she stopped several feet away. "dont worry im just passing through but hey make it to the end so i can pummel you!" she said making me smile as she went after a scared-looking alien. suddenly a giant explosion went off nearby and i felt goku's energy wink out. as dread fell over me i ran towards where it came from praying that goku was ok.
