Its was 90 years after the battle between Yixinglong. In that time born two new kids. One had a pure good heart but the other one a pure evil heart. The bad twin was banned from the earth and lived somewhere in the north galaxy. The other brother Goku Jr grew up and became a great fighter

Dragonball Jr Movie 4

The lost Twin

It was more than 20 years after that happening. Goku Jr lived along and trained on the mountains. He had no idea about all the things in the north galaxy.

In another planet destroyed a Super Saiyan everybody. The rocks were red because the blood and the houses were destroyed. The saiyan looked like Goku Jr but had different clothes.
?: Nobody is strong enough to beat me. I have more than enough power to destroy the univers.
He went a little and saw a rabbit. The rabbit began to run away but the Ki-Blast from the SSJ killed him.
?: I need a space ship. Where can I get a space ship?
In that moment began the sky to be dark. He looked up to the sky and hear a something. Its the voice of Hidorika.
Hidorika: I heard you wanna a Space Ship. And I know why.
?: Who are you?
Hidorika: I am Hidorika and dont worry. The guy, you wanna meet will be here soon. Dont worry.
After that the saiyan became normal and smiled.
?: I am waiting for you, brother. HAHAHAHAHAHAHA!

Meanwhile on the Goku Jr trained more and more to get stronger. His hard training allowed him to be stronger than a SSJ. The animals ran away as Goku Jr showed his power. The strenght could destroy the whole forest but he knew to control his power.
Goku Jr: AAAAAAAAAAAAAAAAAAAAAAAAA!
After a little lightshow, Goku Jr made a little break. In that moment came Vegeta Jr and Cooler Jr to him.
Vegeta Jr: You train to much.
Cooler Jr: How strong you wanna be?
Goku Jr: I train to find a real opponent.
Vegeta Jr became angry as he heard that.
Vegeta Jr: You mean I am not a real opponent?
Goku Jr: Thats not what I meant. You are strong Vegeta but I need a opponent with my powerlevel.
Voice: Goku Jr, can you hear me?
Goku Jr and the others looked suprised.
Goku Jr: Who are you?
Voice: I am the Creator. The Planet Nebolon on your galaxy are the hell. You must stop the bad guys before they come to the earth.
Goku Jr: Ok..guys you heard him.
Cooler Jr: Lets fly to Nebolon.
The Juniors flew first to Dende's palast for a space ship.
Voice: Hahahahaha...its everytime the same. I hope you have fun with your friend.

The Juniors flew to Dende's palast and took the space ship. With the ship they flew to Planet Nebolon. They looked from the window to the Planet. It looked red like blood or a demon planet.
After some hours they finaly were on Planet Nebolon. They came out the space ship and looked everywhere for the bad guy but nobody was here.
Cooler Jr: Looked the ground full with blood.
Vegeta Jr: Everywhere is blood.
Goku Jr: Which monster had something like that?
They flew different ways to find the bad guy but no one found him.
At last came Cooler Jr to a place with many death people. The blood on the ground was wet.
Cooler Jr: I am in the right place. Huh?
He saw somebody who looked like Goku Jr but with different clothes. He looked to Cooler Jr.
Cooler Jr: Goku, what are you doing here?
He went to the mysterios Saiyan.
Cooler Jr: Where you get that clothes and where is your tail? Huh?
Cooler Jr stopped to go because the guys showed him his hand.
?: DIE!
Cooler Jr: AAAAAAAAAAAAAAAAAAAAAAAAA!
He fired an energy beam to Cooler Jr and the shockwaves were strong enough to warning Goku Jr and Vegeta Jr.
?: Hehehehe...huh?
In that moment came Goku Jr and Vegeta Jr to help his beaten friend. Goku Jr went to Cooler Jr.
Cooler Jr: Goku, I knew you never will attack me like that.
Goku Jr: Who did that? And what are you talking? Huh?
He looked to the saiyan and was suprised about that. Vegeta Jr was suprised, too.
Vegeta Jr: Who are that guy? He looked just like you.
Goku Jr: I remember that guy but who is he?
The saiyan went and clapped his hands.
?: Well well, you are finaly here. Brother.
Goku Jr: What? Who are you?
Vegeta Jr and Cooler Jr were very suprised as they heard that.
?: Its time to tell you the true. I am your twin brother and after our born, I was banned from the earth. Grandpa Pan knew my power. As a kid I killed the damn other stupid humans. We could be the ruler of the earth but Pan didnt like that and you are a little baby who was afraid about everything. I hate you, Goku Jr. You get the name from our grandpa and had a great live. I was banned to that stupid planet and fought for my live. I waited every day for a space ship to come back to the earth but first I will kill you.
Goku Jr: I remember you know. You are Diano but you call yourself Turles Jr.
Turles Jr: Yes, you finaly understand it. I am Turles your evil Twin brother and will kill you. HAAAAAAAAAAAAAAAAAAAAA!
Goku Jr: AAAAAAAAA!
Vegeta Jr: HAAAAAAAAAAAA!
Turles Jr: HAAAAAAAAAAAAAAAAAAAAAAAAAAA!
Turles Jr showed his power and transformed to a SSJ.
Turles Jr: HAHAHAHAHAHA! Its time to show you the power of a SSJ! HAAAAAAA!
Goku Jr: GRRRRRRR
Turles Jr punched with golden aura and full power Goku Jr in his face.
Goku Jr: AAAAAAAAAAAAAAAAAAAAAA!
Turles Jr: HAAAA!
Now he kicked Goku Jr to the air and flew to him. Goku Jr fired a Ki-Blast but Turles Jr dodged and kicked him down. Goku Jr stood up and Turles Jr came down.
Goku Jr: Not bad. You can transform like the old days.
Turles Jr: You will never get this form.
Goku Jr: Hehe...than look out. HAAAAAAAAAAAAAAAA!
Goku Jr focused his power and transformed to a SSJ.
Turles Jr was blind for a little moment and as he opened his eyes, he was shocked.
Goku Jr: Well, the SSJ.
Turles Jr: It cant be. You are a SSJ, too? Whatever...you never defeat me. HAAA!
Goku Jr: We will see. HAAAAAAA!
They punched each other. Turles Jr fired his Killer Driver but Goku Jr dodged and kicked him down.
Turles Jr: How can it be? Take my Kamehameha!
Turles Jr's attack flew to Goku Jr but he dodged and punched Turles Jr many times and kicked him to the rocks.
As Turles Jr stood up, Goku Jr fired a Kamehameha and finished the battle.
Turles Jr: AAAAAAAAAAAAAAA!
Turles Jr was to weak to fight and Goku Jr flew to kill him.
Goku Jr: I will never see you again, Turles.
Turles Jr: Damn it.
Hidorika: Dont worry I give you the real Saiyan strength.
Goku Jr and the others were shocked as they heard that voice.
Vegeta Jr: That was Hidorika. I knew something is going on here.
Turles Jr: HAAAAAAAAAAAAAAAAAA!
He started to transform again and made a big lightshow.
Goku Jr: AAAAAA! Whats going on?
Turles Jr: HAAAAAAAAAAAAAAA...HAAAAAAAAAAAAAAAAAAAAAA!
The rocks were destroyed by the shockwaves on the transformation.
As everybody opened his eyes something bad was happening.
Turles Jr was now a SSJ4 but with looked like Goku Jr as SSJ4 but different clothes and bloodred coat. His face looked pure evil.
Turles Jr: Finaly, the SSJ4. Huh?
In that moment came from the sky somebody. It was Piccolo Jr.
Piccolo Jr: Again somebody from Hidorika. That guy freaking me out.
Turles Jr: Than DIE!
Turles Jr fired a Kamehameha to Piccolo Jr who looked very shocked.
Goku Jr: NOOOOOO! HAAAAAAAAAAA!
He transformed very fast to SSJ4 and was gone.
The attack made a big explosionwave.
Turles Jr: HAAHAHHAHAHAHAAHAHAHAHA!
As the smoke was gone Piccolo Jr had no damage.
Piccolo Jr: Grrr...Huh? AAAAAAA!
Vegeta Jr: NOOO!
Goku Jr protected Piccolo Jr with his body. The attack hurt him very bad.
Turles Jr: Hehehehe...HAAAAAAAAAAAAAAA!
Turles Jr attacked with Killer Driver his brother who protected his friends.
Turles Jr: HAHAHAHA! You have a big weakness, brother. You will never be a real saiyan if you protect that losers.
Goku Jr: You idiot. We arent pure saiyans. We are mostly earthling. I trained hard for my power and you? You get the power from Hidorika. You never be a real Saiyan.
Turles Jr: SHUT UP!
He wanted to fire an energy blast but another energy blast hit him.
Turles Jr: Whats going on?
It was Broly Jr in his USJ form.
Broly Jr: KAKAROT! HAAAAAAAAAA!
Turles Jr: What are you talking? Uh!
The attacks from Broly Jr didnt work agains Turles Jr but he stopped him to move.
Broly Jr: KAKAROT!
He fired after every "Kakarot" an energy blast to Turles Jr.
Turles Jr: Stop it or you die.
Broly Jr: KAKAROT!
Vegeta Jr looked very angry. And the others looked to him.
Goku Jr transformed back to normal because he dont have enough power to fight with the SSJ4.
Goku Jr: Vegeta, whats going on?
Vegeta Jr: GRAAAAAAAAAAAA!
Vegeta Jr transformed to a SSJ4 and was ready to fight.
Vegeta Jr: Finaly, I can control the SSJ4 form. I will kick his ass.
Goku Jr: No, Vegeta.
Vegeta Jr looked to his friend.
Vegeta Jr: Whats wrong?
Goku Jr: Please let me beat him. I must beat him for my family. I wanna show him who I am. I wanna be the one who defeat that monster.
Vegeta Jr looked to Goku Jr eyes.
Vegeta Jr: I understand you but word me one, you must defeat him and the next opponent will finished by me.
Goku Jr: Thats a deal.
Vegeta Jr went to Goku Jr and transfered his SSJ4 power.
Meanwhile attacked Broly Jr with everything he had Turles Jr and became weaker and weaker.
After his last attack he became aswoon and transformed back. Turles Jr had no damage from the attacks.
Turles Jr: Damn it. Huh?
Goku Jr: HAAAAAAAAAAAAAAAAAAA!
Turles Jr looked shocked to his brother who transformed again to a SSJ4 and had no damage.
Turles Jr: How can it be?
Vegeta Jr: Hehehe...we have some tricks too...
Vegeta Jr became aswoon because he gave Goku Jr all his power.
Turles Jr: Grrr...
Goku Jr: I was waiting for a real opponent.
Turles Jr: I am your real opponent. Lets fight, Kamehameha!
Goku Jr: Take this, Kamehameha!
The Kamehamehas crushed each other and exploded.
The two brothers smiled about the other one.
Turles Jr: Not bad. You are the frist one with the same power like me.
Goku Jr: Thank and you arent the first one who will defeated by me.
Turles Jr: GRrrrrrrrrrrrrrrrrr...
They punched each other and its looked like they had the same strenght.
After some punches became Turles Jr angry.
Turles Jr: Thats enough!
He flew up and focused his power. Goku Jr looked shocked up to him.
Turles Jr focused all his power for an energy ball with full power.
Turles Jr: I will destroy you and his freaking planet. I am the stronger brother.
Goku Jr: Come down and fight like a man.
Turles Jr: Hahahahahaha...hahahhahaha! I will destroy that Planet!
Goku Jr showed his golden aura and showed his hand.
Turles Jr: Huh? Ok than Die!
He cast the energy ball to Goku Jr.
Goku Jr catched the attack and used all his power to stop it.
Turles Jr: Hahaahhahahaha!
Turles Jr fired some Ki-Beams to explode the attack but Goku Jr countered with his energy.
Goku Jr: HAAAAAAAAAAAAAAAAAAAAAAA!
Turles Jr: What?! Thats impossible.
The ball flew to him but Turles Jr could dodge. In that moment focused Goku Jr his power for the SSJS.
Goku Jr: I will finish you. SUPER SAIYAN SWORD!
Goku Jr used his attack and cut his brother like Trunks by Freezer. But he shout with the sword.
Turles Jr: AAAAAAAAAAAAAAAAAAAAAAAA!
Turles Jr exploded and the sky was shining.

After some hour stood the other Juniors up and Goku Jr was normal again.
Vegeta Jr: What happened?
Goku Jr: We did it.
Cooler Jr: You killed him.
Goku Jr: But without you I never had a change agains him. Thank you.
Broly Jr: KAKAROT`!
Goku Jr: Not again...

Goku Jr fought agains Broly Jr but the peace is for now back. Hidorika's plans didnt work again but he wont give up.

The End

The very original "evil twin" or "evil counterpart" idea. In this story Turles' reincarnation is apparently related to Goku Jr. Probably done because many of us wanted him to be related to him. Hidorika putting his dirty hands in again manipulating others for his gain.

If the execution were better, I think this could be a pretty good story.
