Throughout this campaign, Häyhä basically just ran around doling out head-shots like the ice cream man gives out Dove bars on a hot sunny day in the Sahara desert. His personal best was fucking twenty-five kills in a single day. That's like an entire baseball team!
Back me up and I'll cut a path through these guys. Wait, did I say 'path'? I mean a five-lane blacktop highway with a two-lane service road - and I'm packing a fistful of tokens and a radar detector.
Soldier: You're going up against a whole ship by yourself?
Havoc: Yeah, doesn't seem fair, does it? Maybe I'll shoot left-handed.
I'm gonna fight 'em off
A seven-nation army couldn't hold me back

853.M41. During the decisive moments of the Battle of Steel Cross, Captain Cortez single-handedly slew the Ork Warlord and his entire bodyguard. Cortez had managed to disarm the Ork leader with a twist of his torso after the Ork's sword had become embedded in his ribs.
867.M41. Despite suffering seventeen wounds, including a stabbing wound puncturing one of his hearts, and two serious wounds from enemy heavy weapons, Captain Cortez managed to break through Eldar lines and complete his mission successfully.
892.M41. Captain Cortez defended the breach in Fortress Maladon's wall for twenty-one hours of constant fighting despite overwhelming odds and the loss of his whole squad to several enemy attacks.
903.M41. Captain Cortez fought through the entire Kardian six week campaign without supplies after they had been lost to enemy fire during deployment. He attributed his survival to the Emperor's benevolence which nourished his body better than any food or drink would have.

— Guts, Berserk
Gods... Is he even human? He fights with the strength of a brigade...

One riot, one ranger.

Why is that fucking soldier still fucking alive? Just someone fucking shoot him already!

His whole story involves a feud with the Philistines, people who lived in part of what is now Israel and embraced the long tradition of going to war with the Jews. Or, specifically, the Philistines went to war against just Samson. And, they pretty much lost.
Zuko: Where is my uncle!?
Guard: He busted himself out... I've never seen anything like it, he was like a One-Man Army!
Cyber Leader: We have five million Cybermen. How many are you?
Dalek Sec: Four.
Cyber Leader: You would destroy the Cybermen with four Daleks?
Dalek Sec: We would destroy the Cybermen with one Dalek!
— Doctor Who: Doomsday
David Fairfax: So, what have you destroyed today?
Shane "Scarecrow" Schofield: I've flooded a Typhoon-class submarine, levelled a building, and launched a ballistic missile to destroy a maintenance facility.
David Fairfax: Slow day, huh?
What do you mean, "He's unstoppable?" You are superior to him in every way that counts. You are better trained, better equipped, you outnumber him at least 20 to 1. Do... your... job!
— Nicole Horne, Max Payne
Escape? I didn't escape! Everyone else escaped!
My god. Do we really suck or is this guy really that good?
— Karl Hertz, Shoot 'em Up
Doesn't the enemy value their officers? If so, they shouldn't be sending them to fight me!
I once defeated a hundred knights single-handedly. To me, you two are nothing more than insects.
— Beatrix, Final Fantasy IX.
Loki: I have an army.
For sure, one Mazinger-Z may be hiding no less than 5% of the total combat strength of the world's major military powers!
— Kouji Kabuto, Mazinger Z
Hmm. I just thought of a paradox. Maybe the more people I kill, the less likely I am to be the fall guy. Because sure, they could say I killed five or ten people, but can they really pin dozens, and dozens, of armed military personnel on me?
As battles go, it was one of the most one sided, because that side belonged to Wee Mad Arthur. There were only a dozen or so guards on the plantation, because starving creatures in chains do not, as a rule, fight back. And they never knew who they were fighting. It was some kind of force that sped backward and forward across the ground and then up your trouser leg, leaving you in no heart whatsoever for fighting or, for that matter, anything else.
Punches came out of nowhere. Those who ran were tripped. Those who didn't were left unconscious, It was, of course, an unfair fight. It generally is if you are fighting even one Nac mac Feegle, even if you are a platoon.
Teasle: Are you telling me that 200 of our men against your boy is a no-win situation for us?
Trautman: You send that many, don't forget one thing.
Trautman: A good supply of body bags.
Marine soldier: Hey, Straw Hat ! Where's your army ? Enies Lobby's forces number in ten thousands!
Luffy: Yeah... and I'm alone. GET OUT OF MY WAY!
GOD! How hard is it to kill one Vault Hunter and a walking slab of meat?!

The Lord Ruler held her face close to his own, looking into her eyes. In that moment, she knew the truth. She could see a piece of him; she could sense his power. His...godlike power. He wasn't worried about the skaa rebellion. Why would he have to worry? If he wished, he could slaughter every person in the city by himself. Vin knew it to be the truth. It might take him time, but he could kill forever, tirelessly. He need fear no rebellion.
Do I have to kill everyone around here myself?! Gah, lead by example... can't delegate anything... Y'know, being a One-Man Army isn't actually something you aspire to. You say that because it sounds Badass, not because you literally want to function as an entire army. But, what are my options? Do everything myself, or just die.
