@ROTHY  
Oh, Damn, sounds like I missed a fun thread.

@HamburgerTime  
We were discussing what each user would be like as a boss fight in a hypothetical Derpibooru video game.

What happened here?

I’M GONNA FUCKING WRECK IT WHILE DRINKING YOUR JUICE AND FUCKING YOUR MOTHER AND KILLING YOUR DOG AND RAPING THAT PLUSHY YOU LIKE

Pony: Cloudchaser

“Welcome to the boss level!”  
My kick-ass theme

“I AM THE GOD OF THE BABYLON 5 SECTION, AND THIS HAND SHALL PLACE THAT WILL UPON YOU!!! MEET YOUR END, SCOOTALOOOOOOOOO!!!”
 
Cue music.

Crap, that didn’t work.
 
I don’t fuckin’ think so.
 
Alternatively, as a miniboss:
 
…Let’s rock.
 
Basically, anything from this will do for theme music

Man, I can’t believe I missed this.
 
“So, you think you have a chance against me? I got five words for you pal:

Intro:  
And here I thought you to be another bug to be squashed by my sheer power. Instead, you have bested my generals, killed my pet, and slain my brother. I congratulate you. Now, (pulls out giant halberd) prepare to be utterly destroyed by the diabolical genious of Dr.Bright!!!
 
Song: Acid Vision by Denjin K

Yay, Boss Thread isn’t dead.

Silly mode:  
Oh-ho, I’m impressed you made it this far. But the game’s not over yet. First you face me and my mighty Boss Theme
 
Serious mode:  
I have achieved everything by myself, without the need for others. You think reliance on others makes you strong? Do you truly believe all this prattle about friendship? …Then show me! Lecture me again when you are on the verge of death
 
Omnicidal maniac mode _{^{Because I just happen to be a major Kefka fan.}} :  
Bleh, all this talk about friendship and harmony is sickening! You all sound like chapters from a self-help booklet! Friendship, harmony, love… Non of that junk is enough to fulfill your hearts! Destruction! Destruction is what makes life worth living! Destroy! Destroy! Destroy! Let’s destroy EVERYTHING! UWAAAHAHAHAHAHAHAAAA!
 
Mini-boss mode:  
Who’s up for some fun?

“If you cannot defeat me, then you are not yet worthy of entering the paradise that is Derpibooru!!” THEME: Trap Phantasm (Megaman ZX Advent)

“Well, you’re fucked.”
 
Arena: Canterlot streets, during Changeling invasion.  
Theme: Dance of Thorns.

Quote: You’re no match for me and pony riding Cat-girl team!
 
Battle theme: Cinderella Cage from Imperishable Night.

“Let’s see if you’re bulletproof!”  
And this as my theme.

@64:  
He’s talking about your character in the game.

@ROTHY  
What?  
What are you talking about?

“I suppose I should be impressed with your skills, but I am not.”
 
Theme: Jesper Kyd - Rocky Mountains

Let’s see, my death quote would be something like this:  
“You finally did me in; guess I’ll make this last drink count. <takes last sips and dies>”
 
My area would be the rooftops of Ponyville. It would be set at night, windy, and with a full moon.
