Season 1:
Kid Cosmic and the Rings of Power
- The moment when Kid thinks Jo has DIED. Even if she was okay, it does look like for a second that she was decapitated.
- Chuck non-chalantly disintegrating a Demon Death Dog.
Kid Cosmic y la Niña Gigantica
- Papa G seemingly being crushed by Rosa's fist.
- Rosa killing every single Chuck clone without a second thought. All while she was thinking it was a GAME.
Kid Cosmic and the Precognitive Cat
- Chuck willing to shoot Kid in the head.
- The image of Kid lying dead in Tuna Sandwich's vision, followed by a future that can only be described as pretty grim. While it never happened, it was still messed up.
- Chuck being sliced in half by Jo's portal, even if it was played for laughs.
Kid Cosmic and the Local Heroes
- Zarkon being electrocuted to death. On screen. In a kid's show.
- The Local Heroes, including kids, are forced to watch a battle between two alien armies where every single person dies.
- Rosa accidentally causing the genocide of the Saucer Men.
- The People Eaters somehow managed to capture all of the Local Heroes and were planning to eat them. If Kid hadn't woken up when he did, or if the aliens actually had been interested in the stones...
- The lifeless head of one of the People Eaters that falls from the sky.
Kid Cosmic and the Big Win
- 46 Papa G clones being mauled by the Demon Death Dogs, and Papa G being completely fine with watching versions of himself die gruesome deaths.
- Jo being nearly bitten in half by a Demon Death Dog. If not for her ring, she would have died in front of her mother and friends.
Kid Cosmic and the Epic Fail
- Chuck's taunting nearly led to Kid DECAPITATING him with his fist.
- Kid's cold expression as he sneaks into the houses of his friends and family and steals their power rings. Especially the lack of a Scare Chord or any other background music when his shadow looms over them.
- When the first Kid clone is shot by Chuck's species. You don't find out until right after that it wasn't the real Kid, and it looks like the main character has just been killed.
- In a freeze-frame bonus, if you pause right as one of Chuck's species gets hit with the rocket, you can see the spike IMPALING HIM.
- Kid getting blasted by a laser right after his seeming victory.
- Great Leader calmly throwing Chuck to his seemingly death off of a rising platform.
Kid Cosmic and the Invaders From Earth
- The soldiers ruling over the town. The worst part? Kid is missing and presumed dead.
- The shot of what seems to be a soldier slashed in half.
Earth Force Enforcement Force
- While the Earth Force Enforcement Force are fighting Gortho's clones, you can see one of them getting his neck snapped in the background.
Kid Cosmic and the Bad Good Guys
- Kid's numerous attempts to tell the Earth Force Enforcement Force that the aliens are good lead to near-death for everyone involved.
- The Biker in Black trying to murder the Local Heroes by sending a Demon Death Dog into their van. No one else is concerned when they see what is seemingly the corpses of children.
- The Biker in Black's entire motive is scary for a different reason. He's driven by pure xenophobia, believing that by destroying any and all alien life that comes to Earth, he's keeping it safe the American way. Keep in mind that many real-life villains are driven by that almost exact kind of paranoia.
Kid Cosmic and the Day is Saved
- The Biker in Blacks attempt to run down the Local Heroes.
- Even worse, this triggers PTSD for Kid, causing him to flashback to exactly what happened to his disappeared parents. They died in a car crash, with Kid the Sole Survivor.
- The reveal that the stones are actually the last pieces of the alien's homeworlds, and the fact that Erodius somehow managed to wipe out more that five different races.
- The ending where Queen Xhan reveals that the other survivors are dead.
Season 2:
Kid Cosmic and the Other Stones of Power
- We see Erodius onscreen for the first time, and it isn't a creature of any kind, it's just a huge planet that moves around and tears planets apart, their debris becoming a part of his body.
Kid Cosmic and the Pyramid Puzzle of Pain
- Kid triggering one of the Pyramid's traps that would have crushed him if he didn't have the goo stone.
Kid Cosmic and the Soul Kroshing Loss
- Fantos flat out murders Krosh with a disintegration ray, followed by him taking Jo as his prisoner.
Kid Cosmic and the World is Saved
- During the final confrontation against Fantos, he actually rips off Queen Xhan's arm, and uses it as an electrified whip. He doesn't get far, but still, holy crap.
- Fantos teleporting Erodius to Earth, the planet killer's massive form looming over the entire world.
Season 3:
Kid Cosmic and the Fourteenth Stone
- Jo sneaks away from a mission to look around the PPG headquarters to find all the side characters standing motionless in the same position they were when the Global Heroes left.
- The moment she discovers the truth. It's almost identical to the infamous Operation K.R.O.N.O.S. scene from The Incredibles. She sees different comic books that match their previous adventures scene-for-scene, word-for-word. Then Papa G shows up, and actually starts fighting her due to the next comic being about a defective clone.
- It's after that when Papa G reveals what's really going on. It's equal parts nightmarish and tragic. The world is in fact a Lotus-Eater Machine, making Kid's comics a reality. So basically, EVERYTHING IS A LIE. And Papa G is allowing it on the off-chance it'll allow him to see his grandson's parents again.
Kid Cosmic and the Global Conspiracy
- I.R.I.S.'s increasing glitching in a distorted chiptune song she sings over the credits, until she grinds to a stop and disappears as they leave the fake world.
Kid Cosmic and the Planet Killer
- A rockslide falling on Papa G. He would've died if not for the healing stone.
- Erodius defeats Fantos by restraining him with tethers of lightning and turning the ground underneath him into goo and he sinks into it like quicksand. All the while he screams Erodius' name in desperation. Even the heroes are horrified by what they see!
