Up until the sixth season of the hit comedy series, South Park, Kenny McCormick dies in every single episode. His deaths are always gruesome and brutal as showrunners, Trey Parker and Matt Stone try to make the inevitable deaths fresh, new, and unexpected.
Kenny dies a total of 127 times throughout the series, even has a temporary "permanent" death during season five, and is gone for the entire next season until his eventual return. After that, Kenny once again s the cast as a main character, and though he still often dies, his deaths are geared more to the plot of the series and happen less frequently.
Alexa, Kill Kenny
In a recent episode involving Amazon and Jeff Bezos, Kenny becomes an activist and boycotts Amazon in solidarity with the other strikers of the company. Bezos, who looks like an alien race from Star Trek, doesn't like this and orders his Alexa to kill Kenny for him. The iconic "Alexa, kill Kenny" is said directly in front of Kyle, Stan, and Cartmen, and Kenny is then killed off-screen. At the end of the episode, Cartmen carries his coffin in the bike parade. While this death is off-screen, the fact that Bezos gets Alexa to kill Kenny off-screen is so incredibly brutal.
Underpants Gnomes
The underpants gnomes, who sneak into people's houses to steal their underwear at night, accidentally kill Kenny with a mining cart. The cart lands on Kenny from high above and completely crushes the poor kid. After this, Stan and Kyle say their typical lines with such ease and boredom. As if they are forced to do so every time it happens. Even the gnomes comment on their tone saying things like "your friend just died, we just accidentally killed him," but the two just wave it off with a simple "yeah, yeah, but anyway."
Mr. Jefferson
This was a rare time fans got to see Kenny's actual face and hair and hear his voice since it is always hidden behind the hood of his parka. Kenny disguises himself as Mr. Jefferson (Michael Jackson)'s child, Blanket. Blanket wears an ornate mask, and so the boys decide to put Kenny in the same disguise and use him as a body double for the younger boy in order to try and rescue Blanket from Mr. Jefferson.
After seeing what he thinks is his son, Mr. Jefferson wants to play with his child and proceeds to lift him up and accidentally throws him through the ceiling when he dies.
Syphilis
Kenny starts dating Tammy, a fifth-grader who is rumored to have given another boy some sexual favors in the parking lot of a T.J.I. Friday's. Kenny finds out about the rumor and is immediately excited, expecting the same from his new girlfriend. But Tammy is a changed girl after seeing the Jonas Brothers live in concert, who managed to convince her to wear a purity ring. Tammy convinces Kenny to do the same, but after the events of the episode, the two decide to take them off and head to Friday's. After they make the decision and are seen heading out, there is a cut to Kenny's funeral claiming that the young boy died from syphilis.
Tampons
In "Are you there, God? It's me, Jesus," pressure leads to him bursting with blood.
Decapitated By Ozzy Osbourne
Ozzy Osbourne is a famous musician, and one of his legacies definitely became the rumor where he bit the head off of a live bat while performing on stage. This South Park episode takes that legacy and makes it even more brutal. During a concert in South Park, all the citizens of the town are moshing and enjoying the music of Ozzy, but Ozzy picks Kenny out from the crowd, while still performing and bites his head off.
Kyle's Dad's Mints
During a meeting to discuss some new horrible thing Cartmen has done, the boys and some of their iconic classmates meet up at Kyle's house. Everyone sits around the table, getting ready to discuss the issue at hand while Kenny profusely eats mints from a bowl in front of him.
Kyle tells Kenny not to eat all of his dad's mints but he does so anyway and starts to expand as weird ooze spills out from him. Mr. Broflovski comes into the room and then says they aren't mints at all, but antacid pills. As Kenny dies from exploding, everyone else just kind of stares at him and laughs in a super bizarre scene.
"Permanent Death"
In the thirteenth episode of season five, "Kenny dies," Kenny gets a terminal illness that leaves all of his friends and family actually mourning his death for the first time. His friends visit him in the hospital and try to make his remaining days the best they can be. While this death isn't particularly gruesome, it was a pretty brutal episode for fans of Kenny. The show creators were bored with the gimmick in which Kenny always dies already and wanted to be free from the cuffs to the concept. Kenny remained dead for the season finale of five and almost all of season six, up until the very last moments in the finale.
Potato Heart
This death is definitely one of, if not the, most brutal of all of Kenny's deaths. This death takes place during the South Park movie, South Park: Bigger, Longer & Uncut, and is what initially sends Kenny to hell. After watching a Terrance & Phillip movie, Kenny and Cartmen get into an argument about whether or not they can actually set their farts on fire. After a display gone-wrong, Kenny ends up setting himself on fire and is rushed to the hospital. Many fans would have assumed that the boy would have burnt to death, but instead, his organs are ripped out and heated up with a baked potato someone had left in the microwave. When Kenny comes to again, he is told that his heart has been replaced by the potato and he has three seconds left to live. The potato then explodes in his chest.
Mysterion Suicide
Mysterion is a self-aware superhero, who knows that for whatever reason, he simply cannot die. Or at least, he assumes he can't. In truth, Kenny dies all the time and is reborn each time due to a ritual to honor Cthulhu that his parents attended before Kenny was born. In an effort to show his friends that his power does exist but they keep forgetting, Kenny puts a bullet through his head and makes them all watch. It isn't a particularly gory death compared to others, but it is definitely one of the most gruesome in the series.
