- Dolphins in The Adventures of Dr. McNinja. You could punch out and kill all the gorillas, dinosaurs, giant lumberjacks, ninja, vampires, and ghosts you want, but if you treasure your continued existence, leave the dolphins alone.
- Beemahs from Buck Godot: Zap Gun for Hire are Armless Biped folk the size of a big rabbit. They were created as spies and assassins and eventually turned their masters extinct species despite all safeguards.

- Arguably, the entirety of Bunny is based off this trope, particularly Orange Bunny.

When pressed into battle, Digger has shown herself to be an effective combatant, not only soundly defeating a gang of bandits, but also lecturing them on what poor condition their weapons are in.
- Subverted in these two Dominic Deegan strips. At first it seems everyone's just being cautious, given how deceptive appearances can be on the Wild Edge. Turns out the little furballs really are harmless. They're just accompanied by Big shaggy parents who will rip your head off if you mess with them.
- Lepus, the awakened Fiendish rabbit from Dungeon Crawl Inc. He first appeared in Episode #6, whose original title, "Eat your heart out Monty Python," lampshaded the obvious homage, though he later became a full-fledged character.

- And from the back of the print version of book one: One world's "cuddly" can be another world's "deadly."
- The paedagogusi of Errant Story. They're fairy-type people about the length of a hand. They're also no one to mess with.
- From Fafnir The Dragon, we give you Frogzerkers. As in, normal-sized frogs with spiked collars that can eats the faces off of vampires.
- The Video Games section paid plenty of attention to Gaia Online's MMO aspect, but Grunny from the webcomic has yet to be mentioned. It is a predatory green rabbit that also carries the G-Virus and turns its victims into zombies.

- Northern Edge, Fred Perry's web original Gold Digger tie-in prominently features Wabbits. Cute little rabits with sharp weapons on their tails and mostly nasty personalities.
- Reynardine, in Gunnerkrigg Court. He's apparently a cute little stuffed toy. He's actually a fearsome possessor demon that kills the body of whoever he takes over. He just happens to be stuck in Antimony's toy. For now. An illustrative example.

- I'm the Grim Reaper: Brook wears a cutesy bunny mask and a ribbon tied on his head that resembles bunny ears, but is also absolutely terrifying in a fight, and can kill with ease.
- Kevin & Kell
- Coney Dewclaw might as well be the Trope Codifier. Nobody who doesn't know her beforehand would be able to tell via looks alone that her mother is not only a wolf, but a top-notch hunter. She definitely got her appetite from the same, having left a long trail of the blood and bones of anybody who has attempted to prey on her, her family and her friends in her wake. The picture at the top of the main page might as well be a real-life image of what she is capable of. She has directly saved her siblings, her father, her grandmothers, her grandfather, the entire Rabbit Council, R.L., and many others in separate incidents via her skills/appetite.
- Her dad, Kevin, might count as well, but in the more traditional metaphorical version of the trope. He's three times the size of any other rabbit we've seen in the strip (including his parents and sisternote ) and mostly muscle (in fact, he used to have a side job as a masked wrestler).

- Schlock Mercenary features a species of "cute and cuddly koalazoids" known as the Tausennigan Ob'Enn. The Ob'Enn, despite their small size and disarming appearance, are referred to as the "psycho bears" by every other species in the galaxy, as they have one of the most powerful and advanced interstellar militaries in the galaxy, and are led by a xenocidal doctrine that calls for the destruction of every other species in the galaxy. At one point a mob boss even mockingly calls Petey — an A.I. created by and resembling the Ob'Enn — a "hairy, scary drop bear."

"Kicking a kitten... A grown man punting a kitten who was looking the other way... It was the bravest thing I've ever seen."

He once skeletonized a shark that had the misfortune of attacking him, and went on a holiday-massacring rampage as part of his vendetta against Santa Claus. When he got swallowed whole by a xenomorph-like alien, he burst out of its chest. He's stronger than an adult human, very fast and almost impossible to hit, and a master knife fighter, as well as being almost utterly evil.
- Also in Sluggy Freelance there's "The Evil", 18 (6 + 6 + 6) "demon kittens" with Nigh-Invulnerability, Super Speed and super-ripping-you-apart-abilities that go on a killing spree if they have not had milk in the last 24 hours. Of course, these kittens are literally the spawn of Satan. They show up in two stories found here and here.
- In a filler strip for Something*Positive, Peter Rabbit gets his revenge.

- Tales of the Questor
Quentin: You know, Groonch, there is an old saying in the seven systems about an unarmed Racoonan... pity you never heard it.

- And Quentyn Quinn, Space Ranger lampshades it about the title character's own race to a guard suffering from Suicidal Overconfidence...
- Alternatively, the Redcaps, who bear a marked resemblance to the little dancing mushrooms from Fantasia, till the needle-sharp claws and fangs come out and they leap into your face. Those bright red "mushroom caps" they wear are actually BLOOD SACS, and they've been known to drain an ox dry of blood in moments...
- VG Cats had fun with usual Rat Stomp grade adventure running into less than obvious monster variations. Leo just had to say he's "on a roll today".
- Goblins of Yet Another Fantasy Gamer Comic created a funny midget direwolf breed, Wargi. The little bastards are nastier than they look. And their cuteness is weaponized too.
