Mine is, “Vengenance and goo flow from my veins! I hereby void your warranty and send you back to God!”
And here I thought my battle cry was various curse-words … 
Stalking over the candy store, wielding a bladed baseball bat, cometh Eve! And she gives a vengeful bellow:
“Ares, God of War, be praised! I lay waste to the landscape until everything has croaked!!!”
Who is that, prowling amidst the icy wasteland! It is DaToad, hands clutching an oversized scalpel! And with a mighty scream, his voice cometh:
“I’m going to contort you beyond mortal comprehension, and sever every head in sight!!”
It has a nice flavor. I like it.
These are too long! Try shouting them in the heat of battle. Heck, try remembering them in the heat of battle.
When I was in grad school, our IM sports battle cry was straight to the point, and short, and perfectly expressed our feelings:
Don’t Screw Up!
Hark! Who is that, rampaging along the hotel lobby! It is Slortar, hands clutching buzzsaw hand extensions! And with a mighty roar, his voice cometh:
“I’m going to flog you into a fine spicy powder, and throw you out the airplane door!!!”
Rampaging along the plains, cutting down all who dare stand in the way using a reflective halberd, cometh koeeoaddi! And she gives a mighty howl:
“Blood and souls for my dark lord! I hereby snap and go berzerk!!!”
I live for this stuff, ivylass.
Silly me, and here I’d always thought it was “Eff 'em if they can’t take a joke.”
Skulking across the candy store, swinging a studded crowbar, cometh Amp! And he gives a bloodthirsty howl:
“I’m going to brutalize you beyond your expiration date!”
Oh, and apparently, I am swinging two hardened pitas while I sprint across the tundra.
Fixing a steely gaze upon those intending to purloin the last of the Krispy Kremes zoid pronounces: “I will fall out of the sky and rain upon you with a beating of biblical proportion!”
My favorite one, of course, is probably not even in there: “I’m going to beat you like a Hitler piñata!”
I don’t need some website to tell me that my battlecry is:
“SPOON!”
Oh, if I had a quarter for evertime I did that…
Skulking out of the tarmac, swinging a thorned whip, cometh DeVena! And she gives a spectacular roar:
“I’m going to contort you all the way to Abu Dhabi!”
[sub]I’m liking the thorned whip part.[/sub]
D’oh, beat me to it, Anamorphic
Mine is:
Sprinting over the cliffs, carrying gilded boxing gloves, cometh Wintermute! And she gives a vengeful scream:
“In the name of malice, I lay waste to all I see like a river of pure piranha!”
Well mine said:
Zang! Who is that, running amidst the tarmac! It is Edward The Head, hands clutching a jeweled meat hammer! He bellows thunderously:
“Vengeance and goo flow from my veins! You are made of meat and I am very hungry!!”
Guess I’m glad I like meat!
NP: Motorhead Eat the Rich.
Not in the face!
JuanitaTech, who don’t need no stinkin’ quiz to tell her what her battle cry is.
I usually go with “Cry Havoc and let slip the Dogs of WAR!”… but I LIKE this un!
Hark! Who is that, prowling across the terrain! It is IrreverentTone, hands clutching buzzsaw hand extensions! And with a vengeful bellow, her voice cometh:
“I’m going to flog you until you have puppies!”
Yea, verily: Who is that, rampaging out of the icy wasteland! It is Deadly Nightlight, hands clutching a reflective halberd! And with a spectacular roar, her voice cometh:
“I’m seriously going to brutalize you like a first grade teacher!”
