(And considering how it was done, he likely had had all of his limbs snapped at once, not just his neck.)

Subverted with Nicholas's death in Cyborg 009, since he gets this done to him via Telekinesis.

In a later Jet-centered episode we learn that his cybernetic arm is no more stronger or more resilient than any other human arm (although he has little to no feeling in it). The offhand, blase manner discussed in the trope description is justified here - Jet uses his cybernetic arm. Jet snaps the neck of a syndicate goon after interrogating him.

Cowboy Bebop episode 'Boogie Woogie Feng Shui'.

Choujin Sensen: Tomobiki manages to kill Baron Saijou with his last-ditch effort of telekinesis he used his blown-off left hand to strangle Baron.

She's actually scary enough that at least two Level 5 Espers fear her. She's snapped Kuroko's neck at least twice and Mikoto's at least once.

In A Certain Scientific Railgun, there's the Tokiwadai Dorm Supervisor, who punishes people this way while somehow not killing them.

In A Certain Scientific Accelerator, Seike is a teenage girl who is somehow able to break a grown man's neck with her bare hands even though her powers (control over friction) don't include enhanced strength.

However, since Giselle has a Healing Factor, she also nonchalantly pops her neck back into place.

Later, it also happens to Giselle Gewelle when Ichigo knocks her and her friends through a building.

However, he then gets up and pops his neck back into place.

This happens to Quilge Opie when he gets Hammered into the Ground by Ayon.

Black Lagoon: Balalaika snaps the neck of the leader of the Washimine group in one of the final episodes.

Kasumi Gyoubu from Basilisk kills two out of three of his enemies this way.

To perform the 'neck snap' like in the page's image you would have to be super humanly strong.

However, it looks very different than in the movies, and there is almost always time to 'tap out' before injury, much less permanent or lethal injury. In real life, spinal/neck manipulation is allowed in certain martial arts competitions such as the UFC and other MMA events. It's possible if you can pin your opponent and know where to grab and twist to get leverage.

Even though hangings, for example, were created as a humane way of killing people via a neck snap, if not done from a high enough place with a long enough rope to generate enough force, they will fail to do so, leading to death by Sinister Suffocation. especially if the character getting it snapped is considerably big and strong. The human spine is not to be trifled with! People who actually suffer broken necks tend to have had very hard trauma from falling or a car accident. Note that in Real Life, it takes a considerable amount of strength and/or training to snap a person's neck, note Go ahead and (carefully) check your own neck - it takes considerable effort to turn your own head past its normal stopping point. note A variant involves putting the victim in a front facelock and violently cranking upwards. Sometimes Alice appears to put in an effort (or has superpowers or something) but often is remarkably blase about it. Bob is always killed instantly and usually with his eyes open. Bob just has time enough for his eyes to go wide with the realization of how screwed he is when Alice wrenches his head to the side with a hideous cracking of bone. Catching him unaware, Alice grabs Bob's chin with one hand and his opposite temple with the other. Next to ' Off with His Head!', snapping a person's neck is one of the surest ways to kill someone in media.
