The earth shakes as the oozaru glows... A golden mist like aura emits from the oozaru... With his arms high up in the air, he starts to emit a bright light blinding all around and blowing up dust...
Goku Sr: Amazing... I never thought he would progress to this point so quickly...
The light is gone, the dust settles... Goku Jr now stands alone, wearing nothing but his yellow pants... His hair, black, now has grown to mid-back length. Red fur now covers his arms, shoulders, back, and ribs, along with the tail which starts moving around... His eyes, now yellowy-green, with a red outline around both eyes, stare sternly at Gureiza, who now stands in front of him, a distance away...
Pan: Yea! Super Saiyan 4! Go Goku!
Goku Sr: Excellent, now for the other two...
Goku flies to the other two, but sees them both down on the ground with the others floating over them.
Goku: What did you guys do?
Krillen: Ok... I admit, we did over do it a little bit... But they just won't settle down...
Goku: Oh forget it! No choice now... They have to be awake for this.
With a wave of his hand, the two oozaru shrink back into Vegeta Jr, and Jeri. Their wounds healed, and they start to wake up...
Vegeta Jr: Ugh... What happened?
Jeri: Did we just...
Goku Sr: We can go over that later, for now, just watch... (points towards Goku Jr)
Jeri: Is that... Goku?
Vegeta Jr: That's Goku? Impossible!
Goku Sr: It is Goku. He is a Super Saiyan 4 now.
Back at Goku Jr and Gureiza...
Goku Jr: (looking slightly to the side) They're okay...
Gureiza: The monkey's shrunk... This will make things easier.
Goku Jr: (looking back towards Gureiza) Yes... I now have the power to defeat you very easily...
Gureiza: Peh. Quit dreaming, brat.
A golden aura appears around Goku... He starts walking towards Gureiza, with each step digging into the ground... Pebbles start floating into the air and vapourize.
Gureiza: Grrrr...
Gureiza attacks Goku, but he disappears... Re-appearing behind Gureiza's head, and gives him a roundhouse kick in midair sending him sliding along the ground. Goku then gently floats back to the ground, back towards Gureiza.
Goku: Don't tell me you're already done... I thought we could have had more fun...
Gureiza gets up by blowing away the rocks around him... Engulfed in a purple aura, Gureiza starts attacking Goku wildy... Goku dodges his attacks by doing quick jumps while moving backwards. Goku stops Gureiza by punching him in the face, and leaving his fist there...
Goku: (removes his fist) Are you even trying?
Gureiza: (wipes some blood off face) Hehe... Not really.
Gureiza jumps back, then starts cracking his joints...
Gureiza: It's been so long since I've encountered some one this strong... I want to savior it.
Goku suddenly appears in front of Gureiza and punches him hard in the gut. Gureiza staggers back...
Gureiza: What the...
Goku: I'm not really trying either...
Goku starts pummelling Gureiza with punches and kicks, then finishes with a quick blast of energy sending him flying off... Gureiza quickly gets back up, rocks explode all around...
Gureiza: Damn brat!
Lightning strikes all around...
Gureiza: You will pay for this! Huaaahhh!!!
Gureiza starts glowing bright white and unleashes a massive amount of energy... The energy blows sand and rocks into the air and even starts to push back Goku...
Goku: What is this energy? What is he doing?
After a while, things calm down... The dust settles, Gureiza now has a sleeker white body, with purple patches on top of head, shoulders, and front...
Goku: What's... What's going on?
Gureiza suddenly appears behind Goku, and using his tail, grabs Goku by the throat.
Gureiza: You're not the only one able to transform... Behold my true form!
Gureiza tightens his grip...
Jeri: Goku's in trouble!
Vegeta Jr: Let's go!
Pan: Wait!
Vegeta and Jeri both go Super Saiyan and fly off towards Goku...
Goku: No... Stay back...
Both Vegeta and Jeri punch Gureiza in the chest, but he remains unfazed.
Gureiza: Get lost you insects!
Gureiza expands his chest blowing those two away...
Goku: STOP IT!!!
Goku's aura flares up and grips on to Gureiza's tail trying to pull him off... Then, Goku starts using his tail to wildly hit Gureiza in the face.
Gureiza: (one eye closed) Fuckin monkey!
Gureiza smashes Goku into the ground.
Gureiza: Hehe... What the?
Goku starts powering up taking flight... Gureiza's tail keeps grip but he starts sliding on the ground... Until he is finally lifted off the ground. Goku holds on to Gureiza's tail as he flies, lands a short distance away, and throws Gureiza over his shoulders and onto the ground. Goku breathes heavily... Gureiza quickly fires a blast of energy at Goku, but he dodged it, barely. But Gureiza uses that moment to grab Goku by the throat and lifts him up... Goku powers up instantly breaking his grip and punches Gureiza's face hard. Gureiza punches Goku's face right back. They both start exchanging many blows...
Vegeta Jr: Ugh... Bastard!
Jeri: Amazing... Goku's going toe to toe with him...
Vegeta: I was referring to Goku! How dare he achieve such power before me!
Back at the fight... Goku fires a kamehameha at Gureiza, but he stops the beam of energy using only one of his hands... With his other hand a small ball of energy appears and he throws it into the ground in front of Goku... The ground explodes, sending Goku and rocks flying back. After Goku lands, Gureiza flies in with a hammer punch, but Goku dodges that by rolling up on his back. Then, Goku kicks Gureiza in the head with both feet sending him flying back. Both manage to quickly get back on their feet, and both are breathing heavily...
With one foot in front of the other, hands placed to the side, palms open, Gureiza powers up a yellow energy ball in each hand... He throws them at Goku, but he dodges them by flying away. The energy balls both hit the ground causing a great explosion, and leaving two giant crators... Goku floats above the crators...
Goku: Whoa... That was close...
Gureiza: Got you!
Gureiza suddenly appears behind Goku and grabs him in a bear hug. Goku throws his head back bashing into Gureiza's jaw. Gureiza lets go of Goku... Goku then tries to punch Gureiza, but he blocks and holds on to his fist... Goku tries to punch with the other fist, but that too is caught. Both stare at each other angrily as sparks of energy crackle all around them...
