Goku's POV

I walked past Frieza and the purple haired stranger, my aura bursting into yellow as my hair spiked up and turned golden. I neared King Cold and got ready to fight.

He suddenly rushed at me, and I ducked under him, kicking him up into the air. I flew up and followed him. He quickly recovered and met me with a flurry of punches and kicks. I blocked and dodged them with some effort, and hit him back as well. As far as I could tell, I was winning, but I didn't think he was using full power yet.

Future Trunks' POV

I looked up at Goku and King Cold with wide eyes. I could barely follow their movements, even in my Super Saiyan form.

'I knew he would be strong like my mother told me, but he really is beyond what I could've ever imagined! King Cold is too,' I thought to myself in awe at their fight. 'I hope this doesn't affect this timeline too much, a lot of events seem to be out of place so far. Speaking of different events..'

I turned to Frieza. "How do I know you're not going to betray us at any second?" I questioned in a purposely hostile voice. He turned from the fight to look directly at me. "I won't. That m-..Saiyan," I could tell he was struggling to get the words out, "gave me a second chance, and I decided to take it, although I'm not sure it's the right choice."

'He does sound pretty honest about the whole thing, so maybe he's not lying.' "Well, if you are lying, I'll chop you into pieces," I warned him. I watched as his expression turned to a frightened and intimidated one. 'I think that worked. Now, even if he was lying, he shouldn't attack us while I'm around, if he knows better.'

"By the way, that Saiyan's name is Goku." Frieza nodded in acknowledgement and turned back to the fight, and I followed his gaze.

Goku's POV

I ducked under one of the Arcosian's punches and kneed him a gut, doubling him over. I used that opening and uppercutted him, sending him high into the air. I then flew up faster then him and plunged both of my fists into his back in a hammer motion, sending him plummeting to the ground with a crash.

---------------------------------------------
Authors note: Yes, I am calling Frieza's race Arcosians. I know it isn't the official name for them, and they don't really have one, but that's what I'm calling them. Thanks for understanding.
---------------------------------------------

I lost sight of him due to the dust from the crash. I waited, but when it cleared, all that was there was an empty crater. I sensed his power level behind me at last second and turned, barely blocking a drop kick that was aimed directly at my head. 'I think it's time to end this.'

I used afterimage repeatedly and kept moving in a circular motion, confusing him. He looked around wildly, trying to spot me from the army of afterimages. I eventually stopped behind him, quickly bending my knees and putting both hands behind me, cupping them together. "Kamehame..." He turned around, wide-eyed. "NO!" He shouted, starting to punch me, but it moved in slow motion for me as I shot my arms forward. "HAAA!" A blue light erupted from my hands, completely obliterating him. He was gone.
