The sweet one (Android 21 x male saiyan OC)

Time to train

BAM!

Trunks and Vegeta get knocked into the wall of the gravity chamber by 21. Trunks was just happy to be getting stronger. Vegeta was just getting angrier.

"DAMN IT! I WILL NOT BE BEATEN BY A PINK BUBBLEGUM WASHING MACHINE!" He screamed, rushing towards 21. She, in turn, flicks him with her tail, sending him spinning in the air.

"Sorry if this hurts, Vegeta." 21 said, slapping him with her tail, sending him flying into the wall again. I ran over, hugging her tight.

"Nice job honey! That was perfect!" She wrapped her tail around me, blushing as red as a tomato. Trunks pulled Vegeta out of the wall as I suggested going outside. Trunks and 21 agreed as we walked to the woods nearby. Once there, we all decided to train with each other: Trunks with 21 and myself with Vegeta. I did that to protect 21 as I knew Vegeta wouldn't hold back against her. That and Trunks wasn't as strong as Vegeta.

"Alright. Let's all start in 3... 2..." It was then I felt an elbow to my chin, flying backwards. I realized that elbow belonged to Vegeta as he turned SSB to train. I turned SSJ4 to counter his Blue. We punched at each other, countering each punch with another punch. We locked arms as Vegeta started talking trash.

"No wonder you're dating the washing machine! You're not a real Saiyan! If you were, you would've killed BOTH of them!" He yelled. My aura flared up. I was MAD.

"Well Captain Widow's peak, if you were a decent person, you'd have more compassion for people who need it! People like 21 need sympathy in times of need!" I could tell that got him angry. Well, angrier than normal. He punched me down to the ground, charging his ultimate move. Once I recovered, I started to do the same. I crossed my arms over my chest, forming balls of ki in my hands. Vegeta threw his arms out to the sides before bringing them together with a yellow ball of ki between his hands. We both started screaming as 21 and Trunks started talking to us.

"Honey, be careful! Don't push yourself too far!" 21 yelled.

"Father, don't destroy the planet! We kinda need it!" Trunks yelled to Vegeta, with the usual "Shut up boy!" in response. I saw him smirk.

"FINAL FLASH!" He screamed, a golden beam firing from his hands.

"GALAXY SPLITTER!" I yelled, throwing my hands together, red and blue ki beams combining with each other, a giant purple beam heading for the Final Flash. The beams collided with immense force and power. After 30 seconds of the clash, the beams fizzeled out as Vegeta and I reverted back to base. We walk to each other, patting each other on the back.

"Maybe you are a Saiyan..." Vegeta said, passing out in front of me. Who's the strongest now, 'Getes? Trunks moves Vegeta to the side as I eat a senzu bean. Trunks got ready to start training.

"So Trunks, let's see how powerful you are at the moment." I told him, going SSJ2, not going all out just yet to gauge his strength. He turned SSJ2 as he rushed at me, punching me in the face. I actually felt that. Not bad.

"Not bad Trunks. Not bad. Your version of SSJ2 is stronger than mine. Now go back and try it again with SSJ3." I told him, going SSJ3. He repeated the process, still feeling his punch. Impressive.

"I still feel it. Now SSJ4." Trunks backed up as I turned SSJ4. He charged forward, but instead of punching me, I kicked him in the gut, knocking the wind out of him. He fell to the ground, trying to catch his breath. I helped him up to his feet, powering down.

"First lesson: Never let your guard down. Ever. Got it?" He nodded weakly. We then move on to combat training. Over the next few hours, I teach him a few new moves, including Vegeta's Final Flash and Galick Gun. By then, Vegeta woke up and watched Trunks and I train. After training concluded, we walked back to Capsule Corp . During the walk, I could hear Vegeta chewing out Trunks like "how dare you lose to scum like him! You are my son! You should've destroyed him!" I didn't listen to him. I just focused on 21. I wrapped my arm around her as she wrapped her tail around me. God, I love her. We reached Capsule Corp as Bulma asked how training went. No one answered as we just walked back to our rooms. 21 and I got into bed and fell asleep.
