There Is No Kill Like Overkill/Web Comics

""The 3219 armor-piercing, drill-tipped, rocket-propelled, nuclear-powered, high velocity bullet with pneumatic shaft explosion dampener, buzzing flagellatory membrane, and a miniature camera so you can see the look on his face before you go through it.""
 * Nosfera's husband Brahm, a vampire, is killed by being stabbed in the heart with a cross. This is lampshaded.
 * Schlock Mercenary takes this to heart, especially Kevyn, who wears antimatter grenades on his shoulders. One of those antimatter grenades is capable of slagging a tank, and the other has the yield of a good-sized nuke.
 * Schlock himself runs around with two sawed off anti-tank multicannons and an oversized plasgun. The multicannons are especially ridiculous because he can hook up feeders and, quote, "fire breacher rounds on full auto."
 * One of the most popular books with mercenaries in the Schlockverse, The Seven Habits Of Highly Effective Pirates, contains several appropriate quotes on the subject, as shown in the quotes section for this trope. The one that quotes this trope practically verbatim can be found in poster form.
 * Actually subverted on one occasion, in which Schlock mocks two enemies for aiming anti-tank weapons at him. They tell him that they're not worried about a little overkill, to which Schlock responds, "OK, but you might want to use your anti-tank weapons on those tanks behind you."
 * Schlock's immune system is itself a form of overkill, it allows him to survive practically anything, even including foreign nanites.
 * Once, the PD Fleetmind launched an all-out assault on an entire star system as a diversion, to extract Tagon's Toughs with minimum collateral damage. To quote the UNS Marine prize crew guarding the Toughs: "'Minimal collateral damage' and 'entire star system' do not belong in the same sentence"
 * Richard of Looking for Group doesn't understand the concept of overkill.
 * Pretty much any time they decide to let Richard loose.
 * Riff's anti-vampire, wooden stake gatling Gun from Sluggy Freelance. "Now THAT is one staked vampire."
 * Riff is, in general, a very enthusiastic supporter of this trope. Regard "party favors".
 * Order of the Stick: Familicide. Nothing says "overkill" like.
 * The Last Days of Foxhound: Vulcan Raven's take on the matter: "Subtlety is a thing for philosophy, not combat. If you're going to kill someone, you might as well kill them a whole lot."
 * Anti-HEROES duplicates the Myth Busters quote here.
 * Billy Mays Youtube Poop Suicide Putty: "Call right now and I'll triple the offer! And send you six sticks of Suicide Putty so you can kill yourself six times!"
 * Some of Agatha's death rays in Girl Genius.
 * In Quentyn Quinn, Space Ranger, the Empire of the Seven Systems responded to the (admittedly rather brutal) slaughter of one of their colony ships by incinerating an entire solar system.
 * Black Mage's preferred form of attack - he has been known to vaporize forests, and at one point destroyed a city by accident when demonstrating to its mayor how he would destroy the city if he didn't get what he wanted. He has refrained from using spells in battles where his life was at stake because he viewed anything that wasn't complete overkill a waste of his time.
 * Jeff manages this with a single bullet in Chicanery:
 * Jeff manages this with a single bullet in Chicanery:

""What are you drawing, my son?" "Our church being destroyed by three Godzillas.""
 * Parodied in Sam and Fuzzy with the Non-Disclosure Automaton. Overkill is just one of his many modes.
 * Exterminatus Now: Wildfire thinks Eastwood, Virus, and Lothar don't respect her because she's a girl. So she decides to prove herself by screwing up in the most spectacular way possible.
 * Bug like to use this trope. The bug wishes he could clean his bathroom this way, and a younger the bug wished would happen to his church.

""Don't say another goddamn word. Up until now, I've been polite. If you say anything else--word one--I will kill myself. And when my tainted spirit finds it's destination, I will topple the master of that dark place. From my throne, I will lash together a machine of bone and blood, fueled by my hatred for you this fear engine will bore a hole between this world and that one. When it begins, you will hear the sound of children screaming - as though coming from a great distance. A smoking orb of nothing will grow above your bed, and from it will emerge a thousand starving crows. As I slip through the widening maw in my new form, you will catch only a glimpse of my radiance before you are incinerated. Then, as tears of bubbling pitch stream down my face, my dark work will begin. I will open one of my six mouths, and I will sing the song that ends the Earth.""
 * In Nip and Tuck, the Show Within a Show Rebel Cry features a disproportionate effort to go after one rebel.
 * From this episode of Genocide Man "The old government policy of proportionate response failed in the 21st century. Now the official policy is overwhelming response. Overkill. First and always."
 * From Penny Arcade's "I hope you like text", when Tycho responds to Gabe's opinion that an upcoming Warhammer Fantasy Battle game rips off World of Warcraft ;
