In Angel Down: We never get to see exactly what Ward did to the drug dealer, just that it was gruesome enough to get his entire forearm soaked in blood.
Awful Hospital: When Fern poisons an Animalistic Abomination dolphin with Vibrio vulnificus-laced meat, the comic cuts to her horrified face over a splattered red background, then back to its unrecognizably ruptured remains. Given that V. vulnificus usually causes vomiting and diarrhoea...
While normally averted in Charby the Vampirate Menu tearing apart and eating the scientists in the cabin is shown as a silhouette, and then just the gore encrusted things in the room.
Code Crimson: Zig-zagged in Issue 1 during Miguel's surprise death. We see silhouettes of the murder, followed by a sneering blood-splattered reaction shot, and then his bloody corpse awash in a sea of blood.
Dubious Company's Tiren attacks a group of soldiers off-panel. All the reader sees of the carnage is Sal's squicked out reaction and a bit of blood speckle the wall.
At one point an airship is fleeing from certain death at the hands of a swarm of "Torchmen" (flaming robotic flying killer gargoyles), disobeying direct orders from their inept passenger. First the captain and his first officer discuss the need to ditch every ounce of dead weight, then their passenger arrogantly screams at them for saving his life, then the two give each other a certain look... and suddenly the captain is rubbing his hands together and affirming that "We're not pirates. He didn't count."
Also, we don't actually see what Von Pinn does to Judy, just the Castle Wulfenbach students' horrified reactions. For that matter, we don't see what she did to André (but then, neither did Agatha).
When Baron Wulfenbach kills Lars, we don't see the actual blow. We see Lars' sword break and a blood splash, then in the next panel, the Baron has blood on his coat.
Goblins: The comic featuring a man getting crushed to death by his own armor, complete with eyeball popping out — still draws the line at killing children onscreen.
Used in Grim Tales from Down Below, when the Pumpkinator rips Minnie to shreds, all we see are Lock's, Shock's, and Barrel's horrified faces, Oogie's scary-happy face, and a couple of Minnie's severed body parts flying. However, in the same comic page, we see Junior's horrified face, and the cause of it: Minnie's shredded up body, organs, appendages, and a look on her face that screams "KILL ME!".
Used in Gunnerkrigg Court when we're shown how Mort the Ghost died as a young boy during the Blitz. First, there's a page with a textbook cross-section of the bombs used. Then, a pile of rubble and a bloodied white helmet.
In the Hivestuck arc, a flashback shows how Vriska Serket used Aradia Megido's boyfriend, Sollux Captor, to murder her. The last we see of Aradia in this flashback is the flashing lights on her face from Sollux's Eye Beams, while Aradia looks up at him in confusion and Vriska messages her "Arrivederci, Megido", leaving the readers to assume from there what happened.
When Jack Noir receives Bec's powers, all we see is a brief shot of Bro and Davesprite staring before the screen fades to static.
Another example is after Gamzee snaps. We see him advancing on Nepeta, with his clubs, but we don't see the killing. When we see Nepeta's corpse later, we can't see any of the wounds either.
During Jack Noir's Jailbreakadventure, he conveniently "bes the other (dead) guy" while being beaten senseless by prison guards.
There's a particularly chilling example in Lackadaisy, with the Marigold Gang and an unknown guy in a pinstripe suit. The last panel of the flashback is Mordecai raising an axe above his head, saying "Keep your head still."
After the alien shuttle was shot down, we don't see the full bodies of the alien security team when the general sees it. From what little we do see afterwards, however, it certainly isn't pretty. The soldiers mention that they had found a total of six and a half bodies.
Dan's vivid imagination of what would be the consequence of Gharr falling in the hands of the government: Gharr's exposed innards are obscured by both the figure standing in front of the table as well as the TV static effect.
Muted: We never actually see Chloe getting killed by Strix, but we do see the resulting blood splatter on her mother's face. By all counts, Strix probably crushed her to death.
Happens a few times in Nodwick where the title character (or even someone else) suffers a particularly gory death. In one strip where Nodwick suffers the results of two lethal curses going off at once, the first one turning his brain into spinach-artichoke dip and the second making his head explode, the panel is blacked out with a disclaimer from the cartoonist to say that it's too unpleasant to show, and to say that simply, the curses have gone off. Another example in another storyline is where Yeagar convinces Nodwick to try to steal a fancy and valuable "Elysium Barcalounger" in a wizard's mansion, even though the heroes were warned that everything there was "either cursed, trapped, or both. The reader doesn't see what happens to them, but Artax needs to get a squeegee to help Piffany restore them.
After leading the Priest of Loki to the former friend who'd double-crossed him, Belkar walks away while the Priest noisily vents his frustrations with his mace. Doubles with Reaction Shot when the people who find his body have to identify it by the clothes.
The villain dispassionately watches for six panels while his victim succumbs to a Touch of Death. Not that the victim didn't deserve it, but damn, that's cold.
While Kevyn is setting some of his own broken bones, the narrator pulls back to a long shot, and cuts the audio when he starts screaming and comparing the pus to tapioca.
Something*Positive: PeeJee discovers that her boyfriend has been cheating on her. The next panel shows the exterior of the bar where the gang are celebrating Halloween, then blood splattered on the window as Kyle hits it.
Trevor (2020)`: A spurt of blood flying across the room is all we see of Dr. Smithe’s death at the hands of Trevor.
True Villains has the werewolf Xeke biting a man's head off, seen only in shadow.
Wonderlab: When Rose gets sacrificed to the Staining Rose, their actual death is never shown on-panel, but everyone is shown to be horrified at the sight.
An example from Zombie Ranch is shown here. A child zombie's skull is detonated, but all we see is the resulting splatter on the wall.
of Sniping the Cockpit with a motorcycle-jumping swordsman are shown as a panel of stylized blood splatter on black.
