Vegeta:

Its the all mighty prince Vegeta chilling with the hoes,

I'll beat your ass like a did with all my other foes,

Royal Super Saiyan Blue, the strongest of the kind,

I'll beat your ass even if i have my eye's closed.

With true Saiyan power,

This insect will be beat,

I bow down to no-one, not even that scumback Beerus.

To get up to my level or even surpass me,

This little Bat will need more then the Eternal Dragon Shenron.

Batman:

It's the Bat coming back,

Nah I don't need a dragon,

dealing justice in the night,

Fighting for my life,

I see a spikey haired clown, Im about to break down,

Little prince thinks he's special,

Thinks he's got the crown,

I would buy your planet, if only it wasn't a memory.

Vegeta:

For the Saiyan pride i'll show you how to fight,

Your a little rich punk,

Playing dress up every night,

All your planning and preparing wouldn't be good enough,

I have the blood, the memory,

I've got what it takes to fight,

Saiyans are a warrior race, that a Bat couldn't handle,

Mr.whack as Wayne just got a Vegeta smack down.

Batman:

I take flight in the night,

Vegeta your done for,

The Batman wants justice,

And you is who I have come for,

Arkham city has a new patient,

A Deusional prick,

Who calls himself Saiyan,

I eliminate threats,

Gotham city is protected,

And you have the world recored,

Of coming 2nd place.

WHO WON ANSWER IN THE COMENTS! ;) I HOPE YOU ENJOY!
