Badass Line as you kill...

[Jumplion]

"Hope you like the taste of lead!"
"Eat my shiny, lead-based, death!"
"Send your face my regards!"
"Nighty-Night!"

And other such standard bad-ass lines before I rip my enemies faces off their heads.

Also, my personal favorite;

"Thanks for standing still, wankah!"

 

[UBERfionn]

"I will send you to what ever god you wish."

EDIT:

I HAD AN IDEA

"This is the part where you fall down and bleed to death!"
"I have fought mudcrabs tougher than you!"
Cookie for figuring out the game this is from.

They'll be burying whats left of ya' in a soup can!

 

[diablo523]

"Give my regards to St. Peter, or who ever has his job, only in hell!"(1 Internet if you get the reference!).

Big Lebowski, right?

You have go to be fucking kidding me.

I don't know, it was something I've watched recently, Big Lebowski being one of them. If I can have another guess, I'd say Dollhouse, even though that's also probably wrong.

Try again. Right creator though, you've got it down to Joss Whedon stuff.

Dr. Horrible?

Tell him what he' won, Jonny!!!

Useful as celebration or ominous warning -

*Mess with the best. Die like the rest*

[^=ash=^]

BRING IT ON!!!

This .. in Joe Swanson's angry voice.

 

[bennytheodd]

"Yippie Ki Yay mother-*pop*pop*pop*"
"Swallow this."
"If you say 'knockers' I'll let you live." "Really?!" "Hahahaha-NO*bang*"
"Shut up or I'll kill myself and then you!"

That's all I've got, I'm afraid.

 

[Baron Von Evil Satan]

"Groovy" (mudkip for the reference)
"Morning." (and an average cookie for this one)

 

[HeySeansOnline]

"Do you see this, this is a firearm, and when I pull this trigger a chain reaction will go off causing a small piece of lead half the size of my thumb to accelerate at such a speed that your degenerate skull will be lacking In the ability to protect that pea sized brain you neglected to use WHEN YOU FUCKED WITH ME!"

 

[Faulty Turmoil]

"Listen, I don't really want to kill you. Because... I AM YOUR FATHER!!!"
"...Really?!!"
"Nope."*BOOM* "Headshot..." I'd then turn around and walk away in slow motion whilst putting on my sunglasses, then a massive explosion goes off behind me. Completely destroying my victims body.

 

[The Amazing Tea Alligator]

"I have killed you."
Yeah? Yeah? Anybody else like it?
