As Goku and Janemba face off against each other, Goten slightly opens his eyes and sees the new transformation his father has achieved.
"Wow, dad actually found a level beyond Super Saiyan two. He's really amazing." He thinks to himself while still on the ground.
Janemba then charges at Goku at top speed while the hero prepares for a fight. The monster throws a punch but Goku barely dodges in time. He then throws a kick that Janemba easily blocks with one arm and swings his tail at him. Goku avoids the tail, landing a dropkick to Janemba's face. Janemba shrugs it off, grabs him by the leg and swings him around. While mid swing, Goku lands a kick to the side of Janemba's neck. Goku then fires a Ki blast but Janemba opens a portal infront of his face. This surprises the Saiyan as the ki blast comes from behind him, causing a big explosion.
Goku jumps out of the smoke, charging at Janemba with another Ki blast. Janemba smiles as he teleports to avoid the attack. Goku looks around for his opponent, while Janemba's hand appears through a portal next to him, firing a close range Ki blast into his chest. Goku gets pushed back, taking a bit of damage as Janemba laughs. The monster then opens his mouth, firing a large ki blast, hitting Goku head on, creating a large explosion. Goten grits his teeth, trying his best to get back to his feet.
"Dad..." Goten thinks to himself.
But he can't get up, still unable to move from his fight from Janemba. When the smoke clears, Goku has taken much more damage after that last attack. Janemba then appears infront of him, grabs his sword, charges in and swings it at him, cutting Goku's chest. Goku back flips. Janemba swings again but, but Goku dodges a slash that creates a large crater in the ground. Goku fires a Ki blast, hitting Janemba head on and flies upward. As the monster is surrounded by flames, he smiles and sends up a slash that cuts Goku's shoulder. As Goku clutches his shoulder, trying to stop his bleeding, but Janemba flies up and sends out multiple slashes. Goku is able to avoid some of the slashes but soon starts to get sliced by Janemba's sword swings. Meanwhile King Kai watches in horror.
"Oh no. This isn't good. Goku, you have to do something fast." He says.
Goku slowly floats back to the ground, covered in slashes. Goten clenches his fists, trying to push himself to get back up to help his father.
"Come on... Dad can't beat this guy alone... he knows that but he's still prepared to fight. And here I am... Stand up! Come on stupid body, move! Please." Goten thinks to himself.
As Janemba prepares another sword swing, Goku looks up at him and smiles, barely able to stand on his feet.
"I'll admit it... I can't win this fight on my own. This guy's power is insane, plus he can regenerate and he never runs out of energy... Hey! I'm gonna need some help over here, Goten!" Goku says.
Goten hears his father ask him for help and it triggers something inside of him. Before Janemba can attack, he gets hit with a ki blast that destroys his sword and Goten stands beside his father, ready to fight again.
"I'm ready." Goten says with a smirk.
Goku smiles.
"Good. Let's give it all we got." Goku says, offering his fist.
Goten nods, giving his father a fist bump.
"Yes sir."
The two then charge at Janemba together. Goten throws a punch but Janemba disappears through a portal again. He appears behind Goten, but before he can attack, Goku kicks him in the face. Janemba stretches his hand at Goku, causing him to dip down and land a dropkick into his stomach. Before the monster can recover, Goten flies in and lands a powerful punch to his, sending him flying through a mountain.
Janemba bursts out of the mountain, but Goten flies in, landing a sidekick to his gut. This angers Janemba, sending Goten flying with a burst of energy. Goku uses his instant transmission and quickly catches Goten. The father and son duo then nod at each other, agreeing to do a fastball special, with Goku throwing Goten at Janemba at full speed.
Goten throws a punch, but Janemba blocks it, creating a large crater in the ground. As he blocks, Goku uses instant transmission again, appearing beside him and landing a punch to the side of his body. For the first time, Janemba winces in pain and Goten lands a punch to his face. The two Saiyans start landing strike after strike, the two being in perfect sync with each other and finally overwhelming Janemba. At that moment however, Goku drops out of Super Saiyan three, turning back into his base form.
"Damn, I must be out of energy. This body maybe durable but it isn't unstable, I've reached my limit." Goku thinks to himself.
Janemba takes advantage of this moment and elbows Goku in the face, knocking him to the ground.
"Dad!" Goten yells.
As he's distracted, Janemba lands a backfist to Gotens face and a gut punch that sends him flying. Goten quickly stops himself by planting his feet into the ground with great force, spitting up blood from that last attack as Janemba lands infront of him with a smile on his face. Goten soon smirks standing up straight and wiping the blood from his mouth.
"You can smile all you want, but I know my dad and I did some damage to you...This is where I end you, Janemba."
Janemba glares at the young Saiyan, keeping the same devious smile.
"Janemba." He says.
The two then start walking towards each other, ready to end this once and for all. They soon start running towards each other. Janemba throws a punch, causing Goten to block, landing a right hook to the side. Janemba sends out his tail at him, but Goten steps on it,stopping it in his tracks.
Janemba then throws a punch that Goten blocks, causing the Saiyan to cringe out of pain, sending him back. Janemba quickly dashes at him, not giving him time to breathe, grabs Goten by the face and slamming him into the ground. Goten kips up to his feet while Janemba continues to charge at him. The monster throws a punch that Goten dodges and punches Janemba in the gut, stopping him instantly. The Saiyan then jumps into the air and kicks him in the face, causing blood to fly out of his mouth. As Janemba is still stunned, Goten lands an uppercut, launching him up into the air.
As Janemba goes flying up in the air, Goten charges a large amount of his energy through his fist. Janemba stops himself and quickly shapes another line of bright white light, turning it into sharp pieces of glass. When the glass falls towards him, Goten jumps into the air with his fist up.
"DRAGON! FIST!" Goten yells, launching a giant Dragon through his fist.
The Dragon bursts through the pieces of glass like Ki, going straight towards Janemba. Goten flies straight through the monster, causing the most damage he's taken in the fight. As Goten turns around, Goku appears next to him in his Super Saiyan form.
"Dad?" Goten says.
"We have to hurry before he regenerates." Goku says.
Goten nods, both of them charging up what little energy they have left.
"KA! ME! HA! ME! HA!" They both yell, firing two large scale Kamehameha waves, hitting Janemba head on, destroying every inch of him, not leaving a spec to comeback. Both Goku and Goten are exhausted from the battle they just had.
"Did- Did we get him?" Goten asks.
Goku smiles and gives his youngest son a thumbs up. Goten smiles back and gives his father a thumbs up as well.
