Ah, what a peaceful sunset in Equestria.

Let's check in on Earth,

Still there.

Let's check on that guy.

Not pink anymore.

Why?

He's not mutated.

And?

He's not uncontrollably using ki anymore so it's good for him.

He mastered his massive power.

And he's leaving without destroying Earth.

"Time to find the sons of that fool. This is perfection, I should have planned this before!" He said.

And now he's murdering a fuckton of aliens.

Did I say fuckton? I meant 10 metric fucktons cubed aliens.

Over the course of years.

So peaceful.

And now...

The Mane 6, the Saiyans, Starlight, the Royal Sisters and Spike are going to stargaze!

Unknowingly to all of them...

There was going to be a full moon tonight.

They were all atop the mountain harboring Canterlot.

"Man, this will be perfect for my studies!" Twilight said.

"There are a ton of them out there. Like Namek. And Yardrat. And the now destroyed Vegeta. And the destroyed Arli-" "I get the point." Twilight interrupted.

"And the full moon will make the experience amazing!" Rarity said as Luna lifted the moon and Celestia lowered the sun.

"Yeah! The- Wait, did you say full moon?" Gohan asked.

"Um, yes, I did." Rarity said.

Gohan was afraid. He couldn't stop staring at the moon.

"You guys need to leave, NOW!" He shouted.

"Why?" Everyone asked.

No response.

Gohan's eyes turned red as he stared at the moon.

"Gohan?" Goten asked.

Now everyone could see Gohan's heartbeat.

"What's happening to you?" Celestia asked.

No response.

"OOH! I know! He's gonna turn into this BIIIIIIG monkey!" Pinkie said.

"Frankly, I don't think that's happening." Applejack said.

"Uh... I really think she's right!" Goten said, pointing at Gohan.

His eyes were entirely red, and he really started to bulk up.

"W-We must flee!" Luna said.

"On it!" Twilight said, teleporting everyone to the palace.

Gohan began to develop serious body hair and his jaw enlarged.

***

"W-What's going on!?" Starlight asked.

"Um... I-I really think we should look out the window right now!" Fluttershy said.

Gohan... Was the mighty oozaru!

He was hanging on to the mountain.

"W-What!?" Everyone asked.

Gohan roared loudly.

It could be heard beyond Griffonstone.

"Gohan!?" Everyone asked.

Gohan fired a blast from his mouth at the palace.

Everyone cowered in fear, and took cover.

Not Goten.

He jumped and broke through the window, turning Super Saiyan.

He cupped his hands together and smashed them to the side at the blast.

He was really struggling to even hold it at bay.

But, a little more power gave Goten enough strength to smack it into space.

"Gohan! What are you doing!?" Goten shouted.

Gohan roared in response and jumped at Goten.

Goten, ready to move the fight somewhere else, flew at Gohan's chest.

He used his ki to create a blue aura and sparkles to increase damage dealt.

He smashed himself into Gohan, managing to knock him back.

He flew himself and Gohan far from Canterlot, and all the way to the Foal Mountains.

Well, it was right next to Canterlot but still.

Gohan smacked him away, and jumped towards the nearby city, the Hollow Shades.

Much to the ponies' horror, Gohan began using their homes as ammunition against the incoming Goten.

'I have to get him out of here!' Goten thought as he dodged.

Goten waited for the right moment to strike.

He waited until Gohan would blast him, and then he smashed himself back into Gohan until they reached the Foal Mountains again.

***

"W-What's happened to him!?" Rarity asked.

"This must be why he told us to leave..." Starlight said.

"Why did he turn into that!?" Twilight asked.

"Don't you remember? Gohan told us that when Saiyans have tails and they look at the full moon, they turn into giant monkeys!" Pinkie said.

"R-Really!?" Everyone asked.

"We should've told him it was a full moon, what fools we are!" Luna said.

"W-We can't rely on Goten! We have to help!" Rainbow Dash said.

"But how!?" Twilight asked.

"With friendship. We might be able to calm him down." Applejack said.

"It's certainly a plan... But... Do not get yourselves killed." Starlight said.

"Alright, girls, let's go!" Twilight said.

The Mane 6 gathered near Twilight.

...Except Fluttershy.

"Fluttershy! What are you waiting for!?" Twilight asked.

"W-We have to go near... That big, giant, scary, murderous monkey!?" Fluttershy asked, actually shaking in fear.

"Fluttershy, we will accompany you. We shall protect you to the best of our abilities." Celestia said.

Luna nodded.

"Good luck guys." Spike said.

***

Goten was struggling greatly.

Damaging Gohan was near impossible at this point.

Smashing his body into Gohan isn't working well anymore.

Kamehamehas would do some damage...

But it would never be enough.

Goten was top a mountain, and Gohan was in the distance, smashing his chest and roaring.

"Take this! Kamehame...." Goten yelled, ready to fire the Kamehameha.

Gohan roared in response and began charging his own mouth beam.

Then the Mane 6 appeared by Goten.

"What are you doing here!?" Goten asked.

"Helping you." Twilight said. "Ready girls!?" She asked.

"Yeah!" Everyone said.

The Mane 6 accessed the Rainbow Power.

Goten smiled. "TOGETHER! HA!" He yelled, firing the Kamehameha.

The magic of Friendship was fired at Gohan as well.

Gohan fired back with a mouth blast.

The blast struggle was pretty even...

Until Gohan put just a little more power into his blast.

The blast was nearing the seven.

"It's not working!" Twilight yelled.

"Try harder!" Rainbow Dash screamed.

The extra Friendship was able to move it back slightly.

Goten was giving it his all...

And he gave even more!

The blast overpowered Gohan's quickly.

Gohan, being stupid as a giant ape, didn't put more power into his blast and ended up trying to hold the combined ultimates.

"Just... A bit... More!" Goten screamed.

The princesses, even though their power levels were weaker, aided them and adding their blasts.

The blast was close to engulfing Gohan.

Gohan, in a fit of rage...

...

The blast exploded in Gohan's face.

The ponies and Saiyan huffed and panted.

"Did... Did... We do it?" Rainbow Dash asked.

"I... I think..." Goten said.

But sadly, they were wrong.

Oh, so wrong.

A loud roar could be heard within the smoke!

And a golden aura cleared the smoke.

They all looked in shock.

Gohan was unscathed, and...

His body hair was yellow!

He had turned into the Golden Oozaru!

"Run! You have to leave, NOW!" Goten shouted.

"What!? We can't just-" "DID YOU HEAR ME!?" Goten interrupted Twilight.

"Twilight, we cannot aid Goten this time." Celestia said.

"B-But..." Twilight said.

"You don't understand. His power's increased so much. You'll all die! I care about you, and I can't let you down!" Goten yelled.

Twilight reluctantly teleported everyone else back to the palace.

"Now it's you and me, you big monster!" Goten screamed, using his final resolve of strength to fly full force at him.

His aura was incredibly blue, and sparkles appeared.

Goten smashed himself into Gohan, causing an explosion!

...But Gohan remained unfazed.

Gohan smashed his fist into Goten, and straight into the ground.

Goten struggled to even keep his footing.

And then Gohan decided to step on him!

Goten was really struggling to keep the foot up.

He could feel his muscles tearing, especially in his arms then his legs.

He actually started to cry in pain.

"G-Gohan! Please stop!" He cried.

His arms began to bleed.

"GOHAN!" Goten cried in a desperate attempt to get to Gohan.

But Gohan wasn't himself.

And he mercilessly stepped on Goten.

Goten stopped his crying and only frowned.

"I... I forgive you, big brother." He muttered before he closed his eyes let the foot crush him.

Gohan roared.

***

The ponies and dragon looked in shock from the palace.

"That's it! I don't even know why I bothered to leave him to fight Gohan! I'm going back!" Twilight yelled.

"Me too!" Rainbow Dash said.

"Same here, I ain't about to let Gohan smash anymore things!" Applejack said.

"So do I." Rarity said.

"Same here!" Pinkie said.

"Me too." Fluttershy said.

"You cannot, I forbid you!" Celestia said.

"Princess Celestia, this is the one time I am going to willingly go against your wishes. I'm sorry." Twilight said.

"B-But you'll die!" Starlight said.

Twilight teleported her and her friends.

***

Gohan was flying at Ponyville.

Or, jumping, really.

His jump made it look like flight.

Gohan was on the edge of Ponyville, and he was ready to smash everything in sight.

The ponies looked in shock and fear.

He smashed a house and grabbed another, hurling it into space before roaring again.

The buildings he just fucked up had no ponies, luckily.

And the Mane 6 all appeared.

And they were all scared...

But Fluttershy?

You know what she did?

She had the face of determination, and flew up to Gohan!

"Fluttershy!" Twilight yelled.

She didn't listen.

Gohan threw his giant monkey fist at Fluttershy, and actually missed.

"How dare you. HOW DARE YOU!" Fluttershy screamed at a volume never heard before.

Gohan was about to grab her.

"Do you think you can just go around and destroy building all you want because you can!? DO YOU!?" Fluttershy yelled.

Gohan stopped.

She stood on his gigantic nose.

Gohan grunted questionably in response.

"I will never forgive you for this, you big meanie! YOU WILL NEVER GET AWAY WITH THIS!" Fluttershy screamed, WAY TOO uncharacteristic of her.

Gohan really stopped now.

He actually calmed down. And...

He was incredibly guilty.

He realized what he had done.

He realized how he had been acting.

He could remember and imagine himself...

Seeing Goten...

And watching him get crushed.

A tear came to his imagined self.

He stared at the moon behind Fluttershy, and gently moved her away with his giant finger.

He giant tear came to his oozaru eye.

She was scared again, and flew back to the rest of the Mane 6 in fear.

"Wow... You really got to him." Twilight said.

Gohan developed a yellow aura...

He reached out to the moon with both hands and lightning started to spark around him.

He roared loudly.

He slowly but surely began to shrink.

Most of his body hair turned red, and once he was 1.5x an adult's height, he randomly developed his pants, wristbands, belt and boots again.

At this point, his voice was starting to return to normal.

His hair began to turn black, and his chest lost some of his body hair.

"W-What's happening to Gohan!?" Rainbow Dash asked.

"He... He's shrunk!" Twilight said.

"But is he normal!?" Applejack asked.

"We can only hope." Twilight said.

Gohan was at his normal size again.

But he was still... Transforming.

He bent down, still roaring.

He still had a golden aura.

But he stretched backwards and roared as loudly as he could.

The lightning sparks increased hundredfold, and the moon suddenly turned red.

The terrain within a 50 foot radius was completely destroyed.

Everyone watched couldn't see with the winds Gohan was emanating.

So... One or two houses were fucked.

...Shit.

Smoke covered the area, and the roaring ceased.

As it died down, something new could be seen.

A brand new Gohan.

A Super Saiyan 4!

His irises were yellow on the outside, and black on the inside.

His hair... Relatively the same.

The outsides of his eyes were red.

Only his chest, his head, his hands and a small part of his stomach were not covered in red fur.

He stared at the sky blankly.

"Hey! What's going on!?" Rainbow Dash yelled.

"He looks quite... Different." Rarity said.

Twilight, being the boldest one, slowly inched closer to Gohan.

"Don't die!" Rainbow Dash said.

"I won't." Twilight said before gulping.

She inched closer and closer.

Eventually she was only ten feet away from him.

"Gohan? I need to know, are you still on our side?" She asked, fear evident in her voice.

Gohan snapped out of his trance, and scanned his surroundings.

He slowly held his hand up. "T...Twilight?" He asked.

"A-Are you still on our side?" Twilight asked.

Gohan nodded in response, but felt great shame.

"He's him again!" Twilight said.

The Mane 6 all cheered again.

Gohan scanned his body.

He felt great power from himself...

But the guilt was far greater than any power he possessed.

'How could I have done that to Goten?' He thought as he looked at the palms of his hands. 'Not even Fluttershy forgives me... I'm a monster.' He thought.

"Did I do all of this?" He asked Twilight.

"Uh... Yeah! You went crazy and started smashing everything! Including us and Goten!" Twilight snapped.

Gohan was trying to fight back tears. "Where is he?" He asked.

"I believe he is still at the Foal Mountains. But... What are you now?" Rarity asked.

"Is it some sort of Super Saiyan form?" Rainbow Dash asked.

Gohan didn't answer. He flew away in a flash.

"What is he?" Fluttershy asked.

"Oh, he's a Super Saiyan 4!" Pinkie Pie said.

"Super Saiyan... 4? What happened to 3? How is that a Super Saiyan form?" Rainbow Dash asked.

"3 makes his hair longer and makes him scream and also removes his eyebrows, silly! And this is a non-canon fan fiction, so GT is perfectly fine here!" Pinkie said.

"Canon... Fan what? Where are you getting GT and screaming from!?" Twilight asked.

"What do you mean? You need to keep up with the times on the internet." Pinkie said.

"But nopony here knows what you're saying!" Applejack said.

"Eh." Pinkie said, shrugging.

The denizens of Ponyville began to walk towards the damages.

"Who did this!?" A mare asked.

"Gohan did it!" Pinkie said.

"Pinkie!" The rest of the Mane 6 yelled.

"Oops." Pinkie said.

"You mean Gohan did this!? I should've known, he was gonna turn on us later!" A stallion yelled.

"Don't say that!" Fluttershy said.

"What do you mean? He lured us into a false sense of security and decided to turn on us last second!" A mare yelled.

"Okay, ma'am, FIRST OF ALL," Pinkie yelled before she continued.

***

Celestia, Luna, Starlight and Spike were tending to the broken Goten.

He was still alive, luckily.

But was just barely hanging on.

Starlight and Spike slowly bandaged Goten as the princesses slowly healed him.

It would take hours for this to complete.

"Did Gohan really do this...?" Starlight asked.

***

Gohan went to the mountain harboring Canterlot.

He searched the place for the senzu beans he had.

And he found the pouch.

'Goten... Please hang on!' He thought as he flew at the Foal Mountains.

***

Goten was probably gonna die.

The blood loss at this point was pretty much greater than the amount of healing.

Luckily, a hairy man- I mean, Gohan came from the mountain harboring Canterlot.

He landed nearby, and shocked the ponies and dragon.

Luna stepped up to plate, spreading her wings and getting into a battle stance.

"Stray away!" She yelled.

"Princess Luna, I'm normal!" Gohan said.

"Wait... Gohan?" Spike asked.

"Where's Goten?" Gohan asked.

"He's right here." Starlight said, pointing a hoof at Goten.

Luna turned normal again. "I apologize for my rudeness... What happened?" She asked.

"I transformed. I should've removed my tail the first chance I had." Gohan said, walking towards Goten.

"Why have you received this... This form?" Celestia asked, stopping her magic.

"I don't know." Gohan said, slowly opening Goten's mouth and dropping a senzu bean in.

There was silence until Goten swallowed.

All his wounds had healed.

And he opened his eyes.

"Gohan...? Is that you?" He asked weakly.

"Yes... It's me." Gohan said, averting his gaze to the ground beside Goten in shame.

Goten instantly sprang up and hugged Gohan. "I'm so happy you're back!" He exclaimed.

Gohan was very, very surprised.

"W-What...?" He asked.

'Isn't he supposed to be mad as hell that I tried to kill him?' He thought.

"You're not a giant ape anymore!" Goten said.

Then he realized Gohan was a Super Saiyan 4.

"What's with the serious power?" He asked, breaking the hug.

"I'm not really sure myself... Listen, Goten, I am so sorry I did this. Can you ever-" "Yep!" Goten interrupted.

Even the bystanders were a little surprised.

"What...?" Gohan asked.

"I said yes to forgiveness! I said it before you crushed me with your foot, too." Goten said.

"Y-You... Thank you." Gohan said.

"Excuse us," Celestia said, gaining the attention of Gohan. "we forgive you as well." She said.

"R-Really...?" Gohan asked.

"Uh, duh!" Spike said.

"I tried to rule a village then Equestria, yet you forgave me. Of course we would." Starlight said.

Gohan was happy... But still felt guilty.

Well, mostly because of what he did and also what Fluttershy said.

***

"And that is why we shouldn't turn on Gohan!" Pinkie said.

"What? You just gave us a recipe for chocolate ice cream cake!" A stallion yelled.

"What she MEANT to say was that Gohan has defended Equestria from many threats that not even we nor the princesses could handle. He continues to do that. Are we going to just turn on him just for a single mistake? I mean, aliens came trying to destroy the entire world, and he defeated them, saving us all!" Twilight said.

"But he's turned on US now!" A mare yelled.

"Is he still going berserk?" Applejack asked.

"He's not a giant ape anymore!" Rainbow Dash said.

"Well... Uh..." Some ponies said.

"See? Gohan would never turn on us, and neither should you!" Fluttershy said.

And the argument went on...

Not really, it ended in Gohan's favor.

***

Eventually, the hate on Gohan was gone.

But his guilt wouldn't cease, no matter how many ponies and person forgave him.

Next time, on this really weird and stupid fan fiction...

Shit, can't give a preview.

Author's Notes:

Yeah, I really wanted SSJ4.

So Gohan's current base is: 60,000,000,000.

SSJ4 - I don't fucking know.

Maybe it's 1,500,000,000,000,000. (Basex10x50x50)

Or it's 240,000,000,000,000,000. (Hypothetical SSJ3 x 10,000)

It's not a 10x multiplier, that's for sure.

I dunno, what do you think?

Also, I'm now 50-50 on Sunset x Gohan, and I want to know if you guys want to see it happen. Comment. Now.
