Nnoitra: Everyone knows that!
Kenpachi: But most people don't realize quite how powerful.
Sheik: You're all impulse and reaction instead of thought and action. You have potential, but you lack skill... How did you even manage to defeat Demise in the first place?
Link: Luck, I guess.
"You're good, but you lack discipline."
—Deathstroke to Kano, Mortal Kombat vs. DC Universe
"It's like I know every combo in the game and he keeps pressing the A button!"
— Gibbs, Titan Maximum
Jin: Your stance leaves you wide open, and your moves are totally inefficient. All in all, your fighting style is a mess.
Mugen: You son of a...
Jin: I swear, you are the most undisciplined fighter I've ever known...
Mugen: Shut your damn mouth!
Jin: ...and the only one I wasn't able to kill.
Katara: She's strong.
Member of White Lotus: She lacks restraint.
— The Legend of Korra (commenting on Korra's Firebending in episode 1)
"So you've never lost huh? You defeat all your enemies in one shot. You deflect all attacks away. People like you wouldn't know how to street fight."
— Touma Kamijou, to Accelerator, A Certain Magical Index Episode 14
"[Steilman] doesn't know how to fight. Not for real. He's never had to learn, because he is big and strong and mean."
— Senior Chief Petty Officer Horace Harkness, Honor Among Enemies
"A shame with that physique of yours, you never learned how to fight."
— Dark, Hunting Humans
"The attacks he sends out are just smashing swings with no technique to them. But that's enough. If there is overwhelming power and speed, there is no room for technique. Techniques are something humans invented to compensate for their weaknesses. Weaknesses are something this giant doesn't have."
— Shirou, on Berserker.
He has no idea of the arts of war,
of shield or sword-play, although he does possess
"The machine's good, but the pilot can't bring out its full potential!"
"A beastkin, huh? Her Ars Magus aptitude is average, but her physical tests are off the charts. She would have no trouble taking on a group of two or three people."
—Jin Kisaragi, Heart to Heart, discussing Makoto with Tsubaki
"That's some strength. I'd be more impressed if you knew what to do with it, though."
—Goku to Nappa, Dragon Ball Kai
"With such a lack of skill, that Walker Machine is wasted on you!"
San Francisco is a big karate town: in 1965 there were roughly seven thousand full-time fee-paying karate students roaming around the Bay Area... but in any active bar you can hear a story about a bartender who 'busted up a guy who tried to pull some karate stuff.' It hardly matters how many of the stories are true. The point is valid: the difference between survival and wipe-out in a physical crisis is nearly always a matter of conditioned reflexes. A bartender with scar tissue all over his knuckles will hit faster and harder than a karate-trained novice who has never been bloodied.
—Hunter S. Thompson, Hell's Angels: A Strange and Terrible Saga
"One criticism of Brock's fighting technique is his lack of patience. In his early MMA fights, he tended to frantically whack at his opponents like his mother just deleted his save game. This never really mattered since a sloppy half-punch from Brock Lesnar is an extinction level event for spinal fluid."''
Xykon to Dorukan in Start of Darkness: Hey, you know what really gets under my skin? Proverbially, of course? A century of wizards looking down their damn noses at me. Energy Drain! I know people think I'm stupid. Because I'm not a wizard. Because I get bored easily. Because I have no interest in strategy or tactics or contingency planning. Energy Drain! But see, I've learned a lot over the years since I died. A lot more than I learned during my life. And now I see that planning doesn't matter. Strategy doesn't matter. Only two things matter: Force in as great a concentration as you can manage, and style. And in a pinch, style can slide. Energy Drain! In any battle, there's always a level of force against which no tactics can succeed. For example, all I need to do is keep smacking you with Energy Drains, and soon you won't be able to cast any of your fancy spells at all. Energy Drain! Because yes, I am a sorceror - and this magic is in my bones, not cribbed off of "Magic for Dummies." And I can keep casting the same friggin' spell at you until you roll over and die. You can have your finely-crafted watch - give me the sledgehammer to the face any day. ENERGY DRAIN!
