You were at Ponyville with your friends when your dad came into town

Zoom: Hey kiddo!

You: Dad?! What are you doing here?

Zoom: Well since the battle with Ghidorah, I think you need to work on your strength

Twilight: So he needs to train more?

Zoom: Yeah, I'm going to give you really intense training, in other words your going to fight me again at the arena in Canterlot

Rarity: They have a Arena?

RD: Well of course they would because the royal guard need to train

Zoom: Correct, wanna come?

Pinkie: Yes!

Fluttershy: I wouldn't mind

AJ: Sign me up

Zoom: Well let's go then!

You, Zoom and the mane 6 including Spike came to Canterlot to see your fight with your father

When you arrived you saw a lot of people ready to watch and in the area where the royals were

You all went into that area and met with the princesses

Celestia: Hello everyone

Luna: It's good to see you!

You: Same to you too Aunt Luna!

Cadence: Hello Y/n!

You: Heya!

NM: Oh it's you again

AJ: You got a problem?

NM: Nope I'm just greatful he's here

SA: I wish I could fight someone

Twilight: Why so you can impress the ladies?

SA: Nah just one specific one *blushes*

Rarity: Why are there a lot of people here?

Pinkie: Maybe it's a party!

RD: I doubt that

Fluttershy: There are a lot of people here, is it the whole of Canterlot?

Blossom: Most of the people are here, some people from Ponyville are here too

You: Maybe they're here to see me beat you!

Zoom: Nah I'm going to kick your ass this time

You: *Gasp*

All: What?

You: You said a no-no word!

Zoom:...........

Mane 6:.............

NM:..........

Princesses:..........

Cadence: I may have taught him that

Zoom: Well anyways, when your ready meet me in the arena!

Then they heard a speaker and saw that it was the announcer

Announcer: Ladies and Gentlemen!

Today we have a fight of the ages!

We have the one, the only, the most handsome warrior out there!

ZOOOOOOM!

Then the whole crowd started  cheering as all the females minus your friends and family blush

Announcer: And then we have one of the most cutest things in the world-

Announcer 2: Um Bob, he's actually adorable according to the princesses and himself

Announcer: Um well then Gary thanks for that, One of the most adorable kids around Y/n!!!!!

Then you jump down from top of the arena and do some flips before landing down, making all the girls cheer because like everyone says.....your adorable

You: You ready?

Zoom: Of course I am

He brings out his fire sword, which shocked everyone and triggered one of the flashbacks you had before

Blossom: Is he crazy!

Rarity: Why would he bring out a weapon while he doesn't have one!

SA: He will be fine

You: So your bringing out that sword again huh?

Zoom: Might as well kiddo

You: Well get ready!

You release your blue aura as it spikes up even bigger than before

Zoom: HOLY-

SA: SHIT!

The crowd started to cheer due to the excitement

You wasted no time at all you land a punch at his face and push him back, Zoom gets up but you kick him further away, he recovers and tries to slash at you with his sword but you were just avoiding it easily

You: What's wrong dad, can't keep up with your own kid?

Zoom: Don't get cocky kid!

He manages to land a blow on you, which hurts like hell

You: Ow that's hot!

Zoom: No shit

You: Language!

You spin kick him in the chest and follow it up with an uppercut, when Zoom was sent in the air you decided to finish it all with one last attack

Zero: Hey kid

You: Zero!

Zero: Yeah I'm in your head also, if your planing to do this atomic breath of yours then try to do it from your hands

You: Wait like the kamehameha from Dragon Ball Z?

Zero: Yes just like that!

You: Oh OK!

You cup your hands together and pull it back, then some blue energy appears from your hand but it starts to burn in your hands since your atomic breath is really hot

You: Take this! ATOMIC BLAST!

You release the energy wave as it goes up in the air and approaches Zoom

Zoom: Aww how cute he named it-OH SHIT!

He gets engulfed in the blast as there was a blinding light

Then smoke appeared and they see Zoom falling down and hitting the ground

Announcer: Is he dead?

Zoom: Nope!

He gets up but barely, shocking everyone but you

You: So you can still stand, kinda predictable

Zoom: Predict this!

He charges at you and tries to slash you but you block it with your finger like this

Everyone was beyond shocked since the sword was on fire and you block it with one finger!

Zoom: H-how?!

You: Push ups, sit ups and plenty of juice

Zoom: ..........

You: Basically Zero helped me

Zoom: Oh....

You then punch him in the gut and slap him away with your tail and then you swing again with your tail and send spikes at him that cuts him

You: Woah what was that?!

Zero: Seems like a new move you learnt, the spikes that are on your tail are used for close and ranged combat

You: Wanna see something cool?

Zero: Sure what is it?

You: GRAVITY DEFYING DROP KICKS!

You jump at Zoom and drop kick him and it did look odd since physics won't be able to tell much to Twilight's dismay

Twilight: What is going on?!

Cadence: It's best to ignore it

Blossom: He has been practising this for a while

NM,RD,Pinkie: That's so cool

Then you finally ended the fight with your fist covered in a blue aura and punch Zoom square in the face

Zoom: Well it seems I lost

You: Again

The crowd started cheering for you especially your friends

Spike: Looks like you owe me some royal guard armour

SA: Ah crap

Then when you went back to your friends they were congratulating both of you

Pinkie: What was that laser you fired from your hands?!

AJ: Or those spikes you launched from your tail?!

RD: And that gravity defying drop kick?!

Twilight: Yes especially that dropkick, where is the force and physics behind it?!

You: OK 1 those are some skills I found out except for the dropkick, and 2 it's a secret

Twilight: Tell me!

You: Sorry but all your getting is those spikes and the atomic blast which is my new move, but now I'm tired so can we go home now

Zoom: Yeah I need some rest too, especially since I lost

You: Again

Zoom: Yeah.....again

Meanwhile in an unknown location........again

We see a feminine figure who's beauty rivals The princesses, this was Ghidorah's sister Mothra who is only 2 years older than her own nephew

Mothra: *sigh* Ghidorah why do you have to terrorise Y/n and his family, I wonder If he will be afraid of me? I think he might except me even though I'm related to 3 idiots, wait 2 of then he actually likes so, he will except me, I'll visit him soon! I hope he thinks I'm beautiful!
