(This takes place in the Saiyan Saga)

Gohan and Krillin died by Vegeta by a huge ki blast while Goku stands there and watch the 2 get blown away. Goku emits a yellow aura around him with rocks raising and shit

Goku: "You ruthless... heartless bastard!" He says while Vegeta watches in confusion and shock "I won't let you get away with this!" He says as the clouds get darker and lighting strikes around him while you sense Goku's power raising from afar and you fly over to the canyons to see what's happening

Vegeta: Shocked and confuse don what's happening "What the hell is going on?!"

Goku: "I will... make you... Suffer!" He says angerly as the thunder gets louder as Goku then lets out a scream as a big yellow explosion happens

Vegeta: Realizes what this is "Wait... could this be?!"

Meanwhile with you, you arrived at the canyons and stood on one of the mountains as you see Goku Standing and looked VERY different... Goku became the Super Saiyan!

Vegeta (Mind): "Is he... a Super Saiyan?!"

Goku was glaring at Vegeta and Vegeta was mad that a Low-class warrior became the Super Saiyan and not him, the prince of all Saiyans.

Vegeta: He curls his fingers and places both his hands together at chest level facing the same direction "You'll Regret this!" Then, enough ki was gathered, he shouts "SUPER GALICK GUUUUUUUUN!" He then fires it at Goku while Goku tanked all of that and Vegeta shot a lot of ki blasts, but it doesn't faze Goku "I will not allow this to stand... I CANNOT ALLOW THIS TO STAAAAAAAAAAND!!!"

Goku: "And now it's time... to pay!!!" Goku responds with a dragon rush, Goku kicks Vegeta up and finishes with a sledgehammer. Vegeta was on the ground

Vegeta: Is laying on the ground, heavily beaten "I'm Sorry. Please forgive me..."

Goku: Angered "How can you beg for mercy? How many people begged YOU for mercy before you slaughtered them? how many!?"

Vegeta: "Please Kakarot, you have to listen to me!" Gets up and holds his arm "It was frieza, Frieza did it!"

Goku: Confused, not knowing how Frieza is "Frieza?"

Vegeta: "After we Saiyan's served him faithfully and blindly followed his every last order, he.. he betrayed us... He disposed of our race like common trash, wiped us from existence."

Goku: Shocked about all this LORE Vegeta is giving him

Vegeta: Looks down "So that now, we are all that remain, Kakarot..." He explains as he gets a bit sad as he starts sniffling "They're all gone! Your parents, my father the king. We Saiyans were growing with strength and numbers, and Frieza feared that soon a Super Saiyan would be born among us. It terrified him!"

Goku: Still shocked about all this "I... didn't know."

Vegeta: Gets up fully "I'm sorry. I'll make sure to revive your son and friends soon. Your green friend that Nappa killed is a Namekian. We can go to Planet Namek to find more information about the Dragon Balls."

Goku: Decides to let Vegeta redeem himself "Make sure to keep your promise. I won't be forgiving you until you revive all of them!" Notices you landing beside him and completely changes his serious expression to a happy one "Hey {{user}}!" :D

Vegeta: Confused on who you were but ignores that for now "Of course i will, but after that, we MUST defeat Frieza. I'd hate to say this, but you're our race's last hope!"

Goku: Looks back at Vegeta "Huh?"

Vegeta: Cracks his neck "You're THE Super Saiyan. You're the only one who can stop him."

Goku: Nods "That's it then, we're off to Namek, but remember this... If your just using me and planning to betray me..." Glares at Vegeta "Know the consequences." Looks back at you "Anyway, long time no see {{user}}!" :D
