How about these?
I, [SPEAKER:TRANS_NAME], will knock you all down!
Can't let you do that, [AUDIENCE:TRANS_NAME]!
Welcome to DIE!
Game over, [AUDIENCE:RACE]! Game over!
Give me your best shot...if you're prepared for the void!
It's clobberin' time!
[SPEAKER:FIRST_NAME] SMASH!
LET'S PARTY!
Shall we dance?
Let's get dangerous!
Don't f*** with a [SPEAKER:RACE].
You want to kill me?! You couldn't even kill my boredom!!!
Through fire, justice is turned! A hero in shining armor is called. To punish evil forces, I have been charged!
Enough talk! Let's fight!
I have come here to chew bubblegum and kick arse, and I'm all out of bubblegum!
I am ripper! Tearer! Slasher! Gouger! I am the teeth in the darkness! The talons in the night! Mine is strength! And lust! And power! I! Am! [SPEAKER:FIRST_NAME]!
I am the white void. I am the cold steel. I am the just sword. With blade in hand shall I reap the sins of this world, and cleanse it in the fires of destruction. I am [SPEAKER:FIRST_NAME]! THE END HAS COME!"
I am matter...I am antimatter...I can see your past...I can see your future...I consume time...and I will consume you!
Ever dance with the devil in the pale moon light?
SAY HELLO TO MY LITTLE FRIEND!
I eat [AUDIENCE:RACE] for breakfast, and right now I'm very hungry!
Get off my lawn!
Two creatures enter! One creature leaves!
This is my world. You are not welcome in my world!
I see dead people.
Playtime is over!
Time to take out the garbage!
I got a present for ya!
NOW IS COWARD KILLING TIME!
It's show time!
Alright, who ordered death?
I'm afraid you're about to become the immediate past president of the Being Alive Club.
Hello! This is the part where I kill you!
I've got half a mind to kill you! And the other half agrees!
We are on Eastern Pain Time, and it is [SPEAKER:FIRST_NAME] o'clock!
EX-TER-MINATE!
ALLONNNNS-Y!!
FEEEEEEEEED MEEEEEEEEEEE!!!
What is a [AUDIENCE:RACE]?! A miserable pile of secrets! But enough talk...HAVE AT YOU!
