Broly grabbed Goten by the face and literally wiped the floor with him.

"Goten!" Gohan yelled, trailing after him.

Rainbow Dash followed.

"What the heck is going on!?" Twilight asked.

"I got you brot-" Gohan said before Broly let loose with Goten, sending him sliding across the ground and blasting Gohan away with a green blast.

"Take this!" Rainbow Dash yelled, firing a powerful yellow blast from her hands.

There was smoke around Broly.

A giant hand emerged from the smoke and grabbed Rainbow Dash in the face.

Rainbow Dash desperately clawed at his bulky arm.

He hurled her at the rest of the Humane 7.

Fluttershy caught her.

"Are you okay?" She asked.

"Ouch..." Rainbow Dash said as she got herself standing.

"Let's help!" Twilight said.

"Yeah!" The girls said, powering up, making their individual auras flare.

Except Fluttershy, she was scared out of her mind at the sight of Broly.

"KAKAROT!" Broly yelled, slowly walking towards Goten.

He was nearly out of stamina from that one attack...

His Super Saiyan form was no match for a Super Saiyan Broly, let alone a Legendary Super Saiyan.

And he lost the form.

Rainbow Dash flew after Broly, Applejack lifted a boulder and punched it at Broly, Rarity sent a diamond going at him, Sunset ran at him, Pinkie threw an entire bottle of sprinkles at him, and Fluttershy cowered, still.

Twilight tried using her magic to hold Broly back.

Broly only walked, and broke her magic.

"Ah!" Twilight yelped, feeling mindfucked a bit.

"Are you alright?" Fluttershy asked, helping Twilight stay standing.

"I'm alright..." She said.

Broly turned around and charged at his opponents.

First, he punched Rainbow Dash once, and she was down for the count.

Ponied down.

Then, Rarity's diamond shattered at the mere touch of Broly.

"Ouch!" Rarity yelped, grabbing her head in pain.

Felt mindfucked as well.

Broly tanked the sprinkle explosion, as well as the boulder, and his next victim, Sunset, stopped short.

She was about halfway there, but he's that damn powerful.

Broly cackled as he charged at Sunset.

Sunset braced for impact, and-

"YOU LEAVE HER ALONE!" Gohan screamed, dropkicking Broly right in the side as a Super Saiyan.

Sunset looked to see Gohan starting to push Broly back.

But, she wasn't going to stand idly by.

She had a friend to help.

She went to Rainbow Dash and held her over her shoulder.

By that I mean her whole body.

Head forward. (Her head's in front of Sunset. She ain't checking out the rear.)

What she didn't know was that her hands were glowing orange, yet she wasn't seeing her memories...

Foreshadowing.

Broly broke free and tried to attack with a punch.

Gohan grabbed this giant fist and swung Broly into the ground.

He then kicked Broly quite some distance away.

Broly's face went across the ground.

"Sunset! Get Goten and get as far away as possible!" Gohan yelled.

Sunset did as she was told.

"I'm gonna make you pay, Broly!" Gohan yelled.

"For what you did to Goten and Rainbow Dash!" He yelled, making his aura flare.

Broly got himself up.

"I am going to kill you...!" He yelled.

He made his yellow greenish aura flare.

Gohan was unfazed by Broly's rage.

'Broly... I wish you weren't an enemy.' He thought.

"Broly, you won't win. You may have this... Form, but you stand no chance against me anymore." Gohan said.

"No... I will never stop. NOT UNTIL KAKAROT DIES!" Broly screamed, charging at Gohan.

He smashed his fist into Gohan's face!

Gohan didn't move an inch.

He grabbed Broly's massive hand with one hand and twisted it.

Broly yelped.

***

Sunset got to Goten.

"Alright little guy, you-" Sunset said before suddenly, Rainbow Dash was trying to get off.

"Stop. I'm gonna carry you over there and you can rest." Sunset said.

"What do you mean? I'm totally fine!" Rainbow Dash said.

"What?" Sunset asked, completely confused.

"You were just punched by whatever Super Saiyan form that was and you were down!" She said.

Rainbow Dash managed to get herself off.

"Well, yeah. That hurt. But I feel completely fine for some reason." Rainbow Dash said.

"Y-You're lying!" Sunset said.

"Nuh uh!" Rainbow Dash said, ponying up.

"What?" Sunset asked, carrying Goten in her arms.

Her hands were glowing orange at that time as well.

"Uh... Your hands?" Rainbow Dash asked.

"What do you- Huh?" Sunset asked, looking down at Goten.

***

Gohan let out a war cry before punching him in the gut with his other hand.

Broly coughed loudly.

Gohan wasn't done yet.

He pummeled Broly to nearly no end!

Broly couldn't believe it.

His brand new form reduced to a pile of garbage.

Gohan then blasted him into the rock formation nearby!

Pierced right through him, and right through the stomach!

Put a hole in it for the second time!

Broly lost his Legendary Super Saiyan 3 form and was reduced to a regular Legendary Super Saiyan.

He was panting for his life.

Blood escaped his mouth.

"I can't take any more chances with you, Broly." Gohan said, beginning to charge a Kamehameha in his hands.

Broly was laying in his own anguish.

He could only stare at the sky blankly.

It was around 6 pm, and the moon was kind of out.

A full moon...

"The moon..." Broly muttered.

Then his chest started to beat.

Gohan realized what was happening.

He had to finish it now!

***

"Uh...Huh?" Goten asked as he woke up.

"Goten?" Sunset asked.

The Humane 7 were all together and a good distance away from the action.

"What happened...?" Goten asked as he got on his two legs.

"You're healed! This... This is another part of my magic!" Sunset said, looking at her hands with a smile on her face.

"Huh. Wonder if we have any extra super power." Applejack said.

"That would be so awesome!" Rainbow Dash said.

Then they all saw a very huge blue beam fire across the horizon.

"Well... Gohan won." Sunset said.

"That was a close one..." Twilight said.

Everyone started to pony down.

Goten had a look of fear.

"N-Not quite!" He said.

"What are you talking about?" Sunset asked.

Then, a legendary golden oozaru emerged from the blast, killing it!

Much to Gohan's horror.

'No... No!' He thought.

"What the heck is that!?" Applejack asked.

"Nice... Big... Scary...! Gorilla!" Fluttershy said in huge fear.

"It's what Gohan turned into when he..." Goten stopped short.

"He what?" Rarity asked.

"Turned into a Super Saiyan 4..." Sunset said.

"Wait... Don't tell me..." Rainbow Dash said.

The oozaru roared loudly!

He had yellow greenish fur...

He fired a red blast from his mouth.

Gohan narrowly dodged.

'His power's increased tenfold! Then this!? Now I know how Goten feels.' He thought.

If you don't understand, he meant Broly's base increased tenfold. Then, the legendary golden oozaru, which is about 750x.

That's what I mean.

'I can only hope...!' He thought.

Gohan flew right at Broly.

Broly swung his gorilla hand at Gohan, who narrowly dodged underneath.

Gohan threw a punch, only slightly hurting him...!?

'You're kidding! Super Saiyan can't harm him now!? How!?' He thought.

Broly roared.

Gohan flew back for some distance.

He powered up into a full power Mastered Super Saiyan 2.

"Please be enough!" Gohan muttered, firing another Kamehameha at Broly.

Broly... He jumped away to dodge it!

"What the heck!?" Gohan said.

'He dodged it...?' He thought.

'How am I going to...' He thought, looking at the moon.

"W-What's happening!?" Applejack asked.

"He dodged it!" Goten said.

"This isn't gonna end well!" Sunset said.

"Why is Gohan's Super Saiyan 2 so different now...?" Goten muttered.

(It's the same thing with Trunks. He managed to get on par with SSJ3 Goku with SSJ2 in the manga.

Although Goku held back, he was obviously putting himself at Trunks level.)

Gohan's power was similar to that if he were a Super Saiyan 3.

"What's Gohan going to do...?" Sunset asked.

"Well, duh! He's gonna blow up the moon, then Broly's gonna go Super Saiyan 4, then Gohan will beat him down, then Broly will get ANOTHER zenkai, then he'll beat Gohan down, then we'll jump in, Gohan will be back, and he'll take care of Broly no problem!" Pinkie sputtered.

"Uh... What?" Twilight asked.

"I sincerely doubt that Gohan would blow up the moon. I mean, Equestria's tides will eventually manage, but he knows the importance of the moon here! He would never-" She said before Gohan blew up the moon with a powerful ki blast.

"You were Saiyan?" Pinkie asked.

"Good one!" Rainbow Dash said.

"Girls, this isn't the time for jokes!" Sunset said.

Broly reverted back to his base form...

Receiving the third boost in power in this fight.

This scary boost would even scare Gohan.

Gohan flew down to the ground to see Broly.

Broly was actually seemingly weakened.

"You attained another form of Super Saiyan... I will go higher." Broly muttered.

He stood tall and made his aura flare for a moment.

"The bloodbath begins with you..." He said, enraged even further.

First, Gohan toyed with him.

Then, the sight of Goten made his blood boil.

At this point Broly was more than just angry.

Broly turned into the Legendary Super Saiyan...

Then Legendary Super Saiyan 2... (This is getting repetitive.)

Then 3...

'H...He can't be going Super Saiyan 4!' Gohan thought.

"His power's increasing to no end!" He said.

Broly's rage really broke this time.

Broly exploded with green everywhere.

Everyone was blinded by the light.

Broly came out from it...

Green aura...

Black hair...

Red body hair...

Insane power...

"No...!" Gohan said, in true astonishment.

Broly... He...

Was the Legendary Super Saiyan 4.

"Is he...?" Twilight asked.

"We have TWO!?" Rainbow Dash asked.

Author's Notes:

Oh shit.

We're in some deep shit.

L. Golden Oozaru Broly - 4,125,000,000,000
LSSJ4 Broly (Zenkai) - (unreleased)

And as you can tell from the text...

SSJ2 Gohan - 25,800,000,000,000

Because of the power scaling I'm using to justify it. (DBS)
