The Saiyan of darkness and light: Dragon ball x OC

20 Years later...

"Heya Vegeta." says Goku as he walks up to the capsule corp. building. "What do you want Kakarot." says Vegeta as he stands up and crosses his arms. "You wanna spar?" asks Goku chuckling. "I don't think so." says Chi Chi glaring at Goku. "We are here to have a nice dinner with bulma and her family, not destroy everything by fighting." says Chi Chi as she closes her eyes and sighs. "Goku could you please just hold yourself back this one time." asks Chi Chi looking Goku dead in the eyes. "But Chi Chi..." says Goku putting his hands together. "No Goku, please just behave yourself." Chi Chi then calms down and stands straight. "And I'll allow you to fight Vegeta afterwards." Goku then takes his hands apart and jumps up. "Alright! you got it I'll behave." Goku then lands on the ground and stands straight. "Thank you." Chi Chi then walks inside with Goten following behind her. "So... Vegeta how have you been?" asks Goku scratching his head wondering what to talk about. "Why should I tell you?" says Vegeta. They then both sense a huge amount of ki approaching earth. "Vegeta, do you feel that?" says Goku as he looks at the sky. "Yeah I can feel it idiot." Vegeta then fly's off towards where the energy is gonna land. "Vegeta! wait for me." says Goku as he follows Vegeta.

---Corget's POV---

"2 powerful Ki signatures, but not as strong as me." Corget then looks at his monitor to see Goku and Vegeta. "ah... 2 saiyans, this should be fun." Corget then puts his sword in its sheathe and puts his visor on. "activating landing gear." says the automated system. The ship then hits the ground shaking the ground. The door to the ship then opens and Tony walks out to see Goku in god form and vegeta in blue. "huh... I've never seen this in a saiyan before." says Corget as he jumps down off the ship. "Its super saiyan god, and super saiyan god super saiyan, also known as blue or red." says Goku smirking. "Well that's good to know, I think super saiyan 2 should be able to handle that." Corget then powers up into super saiyan 2. "Don't you dare under estimate us!" yells Vegeta as he charges Corget. "Vegeta wait!" says Goku but its to late. Vegeta attempts to punch Tony but he catches it. "You might want to wait for your friend." Tony then punches Vegeta in the face making him skid across the ground. "You." says Corget pointing at Goku "Your hiding something from me." Goku then looks at Corget in confusion. "Oh, you mean my ultra instinct, yeah about that I can't access it anymore." Goku then scratches his head and chuckles. "Why not?" asks Corget as he flicks his tail. "Wait you have a tail?" asks Goku as he stares at the gold tail. "Yeah... what happen to yours?" asks Corget as he wraps his tail around is waist. "We cut ours off because turning into a giant ape was to risky." says Goku as he stretches. "Well... how did you activate your Ultra instinct?" asks Corget taking off his shirt and as it hits the ground it cracks. "I could only activate it under an extreme situation." says Goku as he stances. "Well... let's recreate that." Corget then rushes Goku and punches him in the face but Goku pushes through and lands a hit to Corget's stomach, but it doesn't faze him. "You might want to put more power behind that." Corget then knees Goku in the stomach and grabs his arm and slams him into the ground making Goku scream out in pain, but Goku recovers and flips back and stances. "Haaaaaagh!" Goku then transforms into blue. "This is what I wanted." then out of nowhere Vegeta punches Corget in the face making him skid across the ground. "Ow... what a cheap shot." Corget then wipes the blood from his mouth. "It's my turn to respond... haaaaaaa!" Corget then turns super saiyan 3. "Let's do this!" Goku and Vegeta then charge Corget as Corget does the same.
