- Avatar: The Last Airbender
- Most of the Gaang fit this, being a team of heroic True Companions who seldom hold back when all hell breaks loose. At the climax, every single one of Gaang's friends was urging him to kill the Big Bad, and when Zuko pulled his long overdue HeelFace Turn, Katara openly threatened to kill him if he ever looked like he would hurt Aang, and she clearly meant it.
- Iroh also fits this trope to a T. He's a kind old man who puts up with his nephew's Jerkass behavior, gives tea to random strangers... and cheerfully maims people who stand in his way.
- Avatar Kyoshi. Though definitely good, she did not believe in Thou Shalt Not Kill and never hesitated to give an enemy what was coming to him. Like a soldier, if an enemy needed dealing with, he got dealt with and that was that, no regrets.
- It should be noted that Thou Shalt Not Kill was Aang's own personal conviction (part of his background as an airbender), and not an aspect of The Avatar. In fact, each and every previous life he accessed while meditating on the misty island was agreed on the point of doing what's best for the planet even though it might be unpalatable to his ethics. Avatar Yangchen, the previous Air Nomad Avatar and thus sharing Aang's pacifist religious beliefs, advised him that his duty as Avatar is to protect the world at any cost, even if means sacrificing his own morality.
- For that matter, Aang himself. Pacifistic, vegetarian, friendly, and take away Ozai's firebending so he can't be a threat again. Seeing how a bender considers their bending to be an essential part of their being, not unlike their very soul, this is a very unpleasant experience, very much a Fate Worse than Death from Ozai's perspective (not that Ozai didn't deserve it, though).
- Monk Gyatso in Book One. The temple was subject to a surprise attack by overwhelming force of supercharged firebenders. This particular Airbender corpse was found atop a pile of at least 20 firebender soldiers. Said temple was the one where Aang learned his pacifistic ways.
- The titular character of The Legend of Korra is this. If you're her friend she's fun and joking, if a bit egotistical. To enemies she's a terrifying Blood Knight, more than willing to give a complete beat-down, and it's pretty clear that she would have been willing to kill at least one of her opponents if she hadn't been...interrupted. In Book Two she actually does kill her uncle Unalaq, and doesn't express any problem with it. Book Three shows that she's not alone: in the final episodes, Mako, Suyin, and Tonraq do not hesitate to use lethal force on their opponents.
- Terry from Batman Beyond is far kinder than his mentor, but while he is Batman and like Bruce will not actively kill, unlike Bruce, he won't save villains from their own fate.
- In The Dreamstone, the Land of Dreams, despite being a Sugar Bowl in every other regard, is actually far more prone to violence than the Urpneys, and can be rather brutal (if not sometimes borderline sadistic) towards those that try to steal their stone, willingly or not.
- Kim Possible, a Disney character no less, is really caring and helpful, even more so as she matures. She has tried to reason with the villains at times, but most episodes have her resorting to her fists to resolve problems.
- The original My Little Pony TV Specials demonstrated this trope at times as well. The series' first villain, Tirek, was straight-up killed — though "obliterated" might be a better way of putting it — by the Rainbow of Light. Their weapon of choice might be a Care-Bear Stare, but the Care Bears these ponies ain't.
- Princess Celestia of My Little Pony: Friendship Is Magic is a loving, understanding ruler who nevertheless sealed her Arch-Enemy Discord in stone for more than a millennium — a period for which Discord was conscious the whole time. Celestia didn't lose any sleep over it because of his personality, and the same goes for the Mane Six after they manage to reseal him. Though they subvert this later when they set Discord free to give him a second chance.
- She also banished her beloved sister to the moon for a thousand years, because the latter was trying to bring about The Night That Never Ends — which would've had omnicidal consequences. That is firm leadership, ladies and gentlemen (though Celestia, by all appearances, did lose quite a bit of sleep over that decision).
- "A Canterlot Wedding" features the villain Queen Chrysalis threatening the population of Equestria with an attempted invasion. Consequently, it also features the Chrysalis having to deal with Princess Celestia shooting Frickin' Laser Beams at her face. To everyone's surprise — including her own — Chrysalis proves powerful enough to defeat Celestia, but none of the fandom seemed to care.
- It's worth noting that in this case, Chrysalis, who's the queen of an Emotion Eater race, was pretty much beyond all power limits during the battle, as she'd been feasting on the love between Shining Armor and Princess Cadence. In the sixth season finale, when faced with the prospect of fighting Celestia (and all of the other Mane Cast) again, she promptly turned tail and fled.
- King Sombra's case is very similar to Discord's in nearly every respect. Bonus points for the method with which he is dispatched upon his return (he is the first and only antagonist in the show to be Killed Off for Real).
- Oh, and Sombra's fate when Celestia and Luna took him down in the past? His physical form was ripped apart and his soul was sealed under the arctic ice.
- The Mane Six are like this too. Twilight Sparkle might be among the most diplomatic and patient members of the cast, but threaten her friends or loved ones and you better be prepared to face weapons-grade magic. Rainbow Dash and Applejack, the former especially, being the most athletic members of the group, tend to waste little time in putting their considerable physical abilities to use despite their respective fun-loving and level-headed natures. Even Fun Ponified Pinkie Pie (who becomes abruptly terrifying when her Berserk Buttons are pressed and wields a cannonnote in combat), sweet and timid Fluttershy (whose Mama Bear instincts manifest in the form of a superpower called "the Stare"), and the sophisticated, ladylike Rarity (who was kicking angry manticores in the face by the second episode) will gladly step up to the plate if you pose a large enough threat.
- Rarity gets special mention because she is shown using martial arts stances. The others have abilities that can be turned to combat. Rarity, on the other hand, set out to master asskicking at some point before she knew she'd be up against monsters with some regularity, and has no fear about leaping into the fray against creatures several times her size.
- The Powerpuff Girls fit this trope to a T. Generally sociable and friendly, they even manage to get along with several members of their Rogues Gallery when the villains aren't actively doing something evil. Nonetheless, their typical approach to crime-fighting is "beat the ever-loving shit out of the bad guys and dump their broken bodies in jail."
- Optimus Prime of Transformers Prime is one of the nicest, most purely heroic characters imaginable. He's also a giant alien war-machine and willing to brutally kill an opponent who has proven irredeemable. It doesn't matter if you used to be his friend. It doesn't matter if you used to be his mentor. It doesn't matter whether you're a human he could easily crush in a fair fight, another Transformer he's on roughly equal footing with, or even a god-like being like Unicron. Once you've crossed that line, nothing else matters any more. You're going down, and going down HARD.
- This is a trait shared by many Autobots (and Maximals) throughout the Transformers franchise, both figuratively and literally. Optimus just tends to embody it best. When your race has "war machine" as a species trait, you tend to be ready when push comes to shove.
- In the G1 cartoon, during a flashback to his first meeting with Megatron and being rebuilt into Optimus, there is a scene where he just blasts holes into 'con after 'con after 'con. In Transformers: The Movie, Optimus literally runs over one Decepticon and blasts several others before he confronts Megatron.
- Alpha Trion qualifies for this as well, for rebuilding him. After all, he knew warriors would be needed, so when two of his friends were injured, he didn't just rebuild them as they were — he rebuilt them as badass Decepticon-slayers. Imagine waking up in the hospital with an Arm Cannon in preparation for the next time you ran into the guy who put you there.
- While they're not like this in all incarnations, the 2003 version of the Teenage Mutant Ninja Turtles certainly fall into this territory. They have no qualms about killing but are generally pretty nice to their friends, and even when they bicker, you can still tell they love each other.
- One particular instance came when Michaelangelo, the most lighthearted member of the group, pulled the pins off the grenades that a soldier of an invading alien force was carrying. He makes a quip about having done so right before the grenades detonate... with the soldier still carrying them.
- Lion-O from ThunderCats (2011) would seem to be soft compared to other Cats, since he is the only one willing to try and convince his enemies to stand down and show them kindness. However, this kindness does not extend to their bosses, such as when he defeats the king of the rats Ratar-O without hesitation. He also doesn't let his compassion get in the way when innocent lives are at stake, such as blowing several Lizard fighters out of the sky in the season finale.
- In Young Justice, Psimon assumes that because M'gann is a cheerful, friendly Naïve Newcomer, she'll fall apart with a Breaking Speech and a selection of her worst fears. It works for about a minute. Then she gets PISSED. (Something which becomes a bit too common after the Time Skip, to the point that the much gruffer Good Is Not Nice hero Superboy calls What the Hell, Hero?.)Psimon: Now now, my pretty. I know you don't want to do anything you'll regret.
Miss Martian: You don't know me AT ALL!
