Race For The Dragon Balls, Begin!

Chapter
[In a dark room, a man similar looking to Yamcha is seen putting a few parts of Broly's clothing in a machine.]

[Man]: It's should be complete by tomorrow, my ultimate creation; Broly Jr!

[He walks out, locks the out and runs into an alley. A day later, two boys, Goku Jr and Vegeta Jr are seen fighting.]

[Goku Jr]: So, Vegeta, you've gotten tougher!

[Vegeta Jr]: Not so bad yourself, Gokid!

[Goku shoots a beam with some might. Vegeta flies into a wall.]

[Goku Jr]: You know it's Goku!

[Goku uses High Speed Rush and Dragon Throw.]

[Goku Jr]: Gonna fight back? Hehe!

[Vegeta Jr]: Ha, what rubbish attacks!

[Vegeta uses Kamehameha and hurts Goku.]

[Goku Jr]: Not bad...

[Goku headlocks Vegeta and uses Explosion.]

[Goku Jr]: ...For a sissy!

[He goes Super Saiyan.]

[Goku Jr]: You're gonna lose!
