Naruto: You bastards...I'M GONNA FUCKING KILL YOU!!!
Tsunade-Sama was threatened to be killed by Jiraiya, after he deduced that she led negotiations with Orochimaru, if she would commit any kind of treason against their home village (Such as restoring Orochimaru hands. Orochimaru made it quite clear that his first deed with them would be to annihilate the home village).
Another instance in the anime when Sai insults Naruto's size after Naruto insults his drawing has Naruto saying "Let me be perfectly clear. I hate you!" But when he says that it sounds like he's saying "I...KEEL YEW!"
He says this to Haku too much earlier.
And to Mizuki in the FIRST EPISODE. Actually, looking back, Naruto is pretty quick to say it.
Despite having racked up, after 515 chapters, a body count of precisely zero.
Kakuzu: That wound on your neck is ugly. Cover it up. Hidan: Hey, my hitai-ate [Japanese for "forehead protector"]! Wow, you actually picked it up for me? Kakuzu, you can be a nice guy when you try! Kakuzu: Shut up, Hidan! Come on! Hidan: Hey! Wait a sec! Yo, Kakuzu! You may act like a prick, but you really like me, don't you? Kakuzu: Keep talking and I will kill you. Hidan: Aw, don't get shy on me...

In the official translation of Ichigo Mashimaro, Chika, who has been chucked in the bin, says this out of frustration when her sister and their neighbor come back in to watch her struggle to get out:
Taken much more seriously in Chapter 265, though it's Nodoka's artifact revealing Negi thinking this, as he couldn'treallytalk at the moment. It gets to the point that every single page turns completely black from the overflowing threats. Every single inch of every single page
Gundam Seed: Yzak towards Kira, or rather 'The Pilot of the Strike' to him.
Except in the edited-for-Toonami dub, where he says, "I will destroy you".
Tentai Senshi Sunred: Hellwolf says "Kurochu!"- translated by ANBU as "I kill youz!"
Usually, monsters from Florsheim say this to Sunred before attacking him. And then, they get beaten to the pulp.
How many times did Sesshoumaru calmly say to Jaken, "Shut up, I'll kill you." or "Urusai, korosuzo." The fact that Sesshoumaru even bothers warning Jaken implies that he's not planning to go through with the threat, though.
Vincent says a version of it in Bizenghast, in reply to Edaniel's quirkiness: "I am going to kill you right in the face."
Full Metal Panic!: Sousuke says this to Gauron... how many times? Every time Sousuke says this in a rage, Gauron tends to respond in ecstasy along the lines of: "Oh, I'm SO HAPPY Kashim!!" Which tends to end with Sousuke blasting him to bits... only for it to happen again. Hey, the guy's a cockroach.
Also:
Kaname:HE'S LATE!!! What is that idiot thinking, being completely out of reach two days straight?! He still has the notes I let him borrow! I couldn't do my homework, I'LL KILL HIM!!!
Of course Sousuke forgot about it but he didn't get anything other than spanking with the Paper Fan of Doom.
Miura from Yotsuba&!, despite her boyish mannerisms, is actually quite squeamish about certain things (in contrast to the more girly-seeming Ena, who has no trouble with dehooking or cleaning fish and thinks frogs are cute). When taken on a fishing trip, she balks at being given bait, thinking it's going to be a worm. It's a grub instead. She is then offered salmon roe as a replacement.
Miura: That's way better than some grub! I'm gonna kill you!
Noir: Part of the arrangement between Mireille and Kirika.
Bleach: Yumichika in this clip saying "I'll kill you!" with a scary raep face, although it was just the fake soul in his gigai.

Black Lagoon: In episode 15 Revy tells Gretel, who just told her they're Not So Different, "Look, I really don't give a shit. If you fuck with him (Rock) again, I'll kill you. Not to mention, if you say anything to piss me off I'll kill you for that too."
Pani Poni Dash! LOVES this trope to the point where it's close to a new genre: "Threatning Black Comedy". Seriously, it's kinda abused.
Miyako throws the most over-the-top version of the trope by the fourth episode:
Miyako: I HOPE YOU DIE, YOU MISERABLE BIIIIIIIIIIIITCH!!!
In the English dub for Fullmetal Alchemist: Brotherhood episode 58, Mustang uses it quite well when put in a helpless situation.
Gold-toothed Doctor: "We just need you to open the portal and then return."
Mustang: "No, not a chance! I won't be your puppet!"
Gold-toothed Doctor: "I told you, we've run out of time." *Soldier restraining Hawkeye slits her throat, letting her fall limp on the floor.*
Mustang: *silent for a beat, shocked* "LIEUTENANT!...LIEUTENANT!! LIEUTENANT!!!"
Gold-toothed Doctor: "Now then, maybe you've had a change of heart. What say you Mustang?"
Mustang: *still restrained* "I'LL KILL YOU!!!"
It may be worth noting that his voice even cracked during his empty death threat.
Near the end of Black Cat, Creed screams this at Train when it becomes clear that the latter isn't going to join him. The fact that he goes One-Winged Angel in the process makes it pretty clear that this is also the start of Creed's final Villainous Breakdown.
In his first appearance, The Joker was not played at all as funny, even in a dark way. He was, in fact, a permanently smiling psychotic gangster with no sense of humor whatsoever. In his first fight with Batman, Bats is actually the one making puns, Joker's Line? "I am going to kill you!"
Throwaway line in the first Sam and Max Freelance Police comic, as they walk past the office of their neighbor, private investigator Flint Paper, who is in the middle of a brawl with some random Mooks. Paper's unconcerned with the violence and is about to throw a chair at one Mook, who is aiming two guns at him while shouting "AH KIH YEW!"
Invoked unwisely in Daredevil; Bullseye and Daredevil go on a city-wide rooftop chase after Bullseye murders Daredevil's ex-lover Elektra. It ends with Bullseye dangling in Daredevil's grip over a long drop...until he shouts "Kill you! I'll kill--" and Daredevil drops him.

In the Shaman King fanfiction A Gift of Love, this practically a stock phrase for Ren. He says it more than ten times. Ren II also threatens a few people in this manner in return for harming Lien. Most of the other characters that say it do so half-heartedly when they're annoyed and not with any murderous intent.
Becomes part of one of the most dramatic plot points of 12 Angry Men. The defendant, on trial for his father's murder, was heard shouting "I'm gonna kill you!" at his father earlier on the night of the murder. Juror #3 (the one leading the effort to convict, and clearly the most emotional juror) makes a point of this, stating that "anyone who says 'I'm gonna kill you' the way he said it, really means it". To disprove Number Three's point, Juror #8 (the one who was doubtful of the defendant's guilt from the beginning) proceeds to fling verbal barbs at Number Three, suggesting that he's trying to get the defendant convicted and executed "because he personally wants it, not because of the facts", and calling him a self-appointed public avenger and a sadist. This last remark is what makes Number Three snap.
Juror Three:* angry to the point of needing to be restrained by other jurors* I'LL KILL HIM! I'LL KILL HIM! Juror Eight:* entirely calm in the face of all this anger* Now, you don't REALLY mean you'll kill me, do you?
To put things into context, this is just after the Bride snatched out Elle's remaining eye and squashed it underfoot, then left her alive. This is very much a Villainous Breakdown on Elle's part.
To put that into more context, Elle is now blind and in a trailer in the middle of the desert. With no way of finding her way to safety. With an extremely venomous snake somewhere on the floor. Basically, the Bride didn't want Elle's death to be quick.
Bryan Mills: If you let my daughter go now, that'll be the end of it. I will not look for you, I will not pursue you. But if you don't, I will look for you, I will find you, and I will kill you.

Let him do his own fighting. Gordie: Sure. You only outweigh him by 500 pounds, Fatass! Milo: I know your name. You're Lachance! I know all you guys, and all your fathers are gonna get a call from me! ...Except for the loony up in Togus. Teddy: I'm gonna kill you! Son of a bitch!
If you think anything can top Taxi Driver, I'll kill you!

Played for humor when Buffy knocks down a vampire who snarls, "I'll kill you for that!" Buffy responds, "For that? What were you trying to kill me for before?"

A long-running gag on Mystery Science Theater 3000 was for Tom Servo to speak for movie characters by saying "I WILL KILL YOU!" in his patented Mighty Voice at points when it seemed appropriate (or ironically inappropriate).
In earlier seasons there was a separate gag with Joel and the 'bots pleading with the movie, the universe, or the other characters to "Kill him!" This was reserved mostly for Plucky Comic Relief characters that were lame and unfunny.
