"Fillies and gentlecolts!" The humanoid changeling shouted, piercing the roar of the crowd, "Today, we're going to try something...different. As you all know, we like to kick off our concerts with something truly epic...that's not changing. But this? Today? We'll sing a song about a hero of legends here in Equestria. This is, in many ways, her song. I hope you all enjoy...The Ballad of FireFly!" The crowd gasps and roars with glee, unsurprising considering there's so many myths about the First Wonderbolt. And boy oh boy will they get a SHOCK!

Knightmare: Alright, gang! HIT IT!

The song begins, slow and quiet, depicting another peaceful day over the village of Ponyville. Then, suddenly, SONIC RAINBOOM! The song's main riff belts out, spilling into an industrial metal beat that gets many ponies' heads banging right then and there.

Getadelt wird wer Schmerzen kennt

The second speed barrier, that of Magic, is broken, unleashing FireFly's favorite attack, the Wonderbolt!

vom Feuer das die Haut verbrennt

The third speed barrier, that of 'wind' is demolished, unleashing Tornado Alley!

Ich werf ein Licht

The fourth is wrecked, 'nature' shattering to reveal the Psychlone!

in mein Gesicht

Number five, the barrier of 'Force' breaks, wreathing the source in the fire of Friction's Meteor!

Ein heißer Schrei

The sixth speed barrier, that of 'Energy' is destroyed, wrapping the source in a white bullet of radiation, the mythical 'Supernova'!

FireFly!!

The source of the mind-breaking speeds reveals itself to be a particularly BADASS Pink pegasus with a blue mane and tail, just in time to see her break the seventh speed barrier, that of Time Itself!

Bang Bang!
Bang Bang!

Geadelt ist wer Schmerzen kennt
vom Feuer das in Lust verbrennt
Ein Funkenstoß
in ihren Schoß
Ein heißer Schrei
FireFly!!

The Legendary Hero, FireFly, rockets across time and space, fighting everything from ancient Earth Tyrants to futuristic mechanical monstrosities, righting wrongs in the most epically badass and blindingly FAST manner possible.

Bang Bang!
Bang Bang!
FireFly!!

Gefährlich ist wer Schmerzen kennt
vom Feuer das den Geist verbrennt
Gefährlich das gebrannte Kind
mit Feuer das vom Leben trennt
Ein heißer Schrei
FireFly!!

She jets back into the Timestream, brohoofing the Doctor before drifting out

Dein Glück
ist nicht mein Glück
ist mein Unglück

FireFly breaks out and steadies herself, taking aim at a mass of floating islands, all of them armed to the teeth with magi-cannons, preparing to attack modern Equestria

Dein Glück
ist nicht mein Glück
ist mein Unglück

Firefly rockets forward, breeching the first six Speed Barriers....

Bang Bang!
Bang Bang!
FireFly!!

She begins SLAMMING into the multitude of floating islands, ripping them to shreds with sheer velocity, ripping them all to shreds before jetting back into the timestream, popping out right above the concert, the 'illusion' vanishes, as Knightmare points upwards, revealing Firefly ACTUALLY THERE!

Bang Bang!
Bang Bang!
FireFly!!

The Time-Breaker herself flies around the concert, slapping hooves with various ponies and griffins and khajiit before flying up and doing an aerial backflip, slipping behind the stage and setting off a mass of fireworks, sliding under Knightmare and grabbing his microphone right in time to steal the last line!

FireFly: Bang Bang!!
