"Join us and your pain will go away."
- The "Grand Tour" arc where Pan is turned into a doll. She can't make a sound, Goku and Trunks have no idea where she is, the bastard is trying to undress her, the doll room is filled with other people who seemingly were turned into dolls a long time ago, and died (they are at least completely silent as one can't hear their thoughts like one can with Pan's), Goku and Trunks walk by the room many times and she just sees them leave... It doesn't help that the Spanish episodes were shown Out of Order so if one were unlucky, one would never know how it ended...
- It is heavily implied during M-2 the Machine Mutants were actual living beings who had their planet's population wiped out and forcefully converted into robots to be used as warfare. The concept by itself is terrifying, but then you remember that one of the main characters is part of said robots, and the other three were very close themselves to becoming Machine Mutants if it were not for him.
- Baby. Basically an anime version of the Thing, Baby is a supremely vindictive mutant parasite that infects all but a tiny handful of people on Earth, taking complete control over them, and when he picks a main host body, his power warps it to completely unrecognizable levels while enhancing its abilities. Even worse was that, in his earliest stages, instead of controlling people he infected, he ate them, wiping out entire spaceships full of passengers, including children.
- Baby's victims. When they're infected, they seem to retain their memories, powers, and personalities from before the infection albeit with now complete sadistic malice for anything that isn't infected like themselves. For example, Bulma is still able to invent, and all the Saiyans are still able to go super, meaning their talents can now be used for evil. It gets especially bad when we see things like a possessed Trunks fighting his closest friends, a possessed Gohan making quick work of his former mentor Piccolo, and Gohan and Videl beating up Pan, their own daughter, seemingly for no real reason other than simply pure malice.
- It really, really doesn't help that some of Baby's interactions with his victims can sound like he's sexually assaulting them. The worst of which is probably when he takes over Trunks' body while possessing Vegeta.
- Baby's possession of Vegeta in episode 27 is particularly disturbing to watch. The parasite enters his wounds and decides to take his time and talk with Vegeta before taking him over completely. At one point, to show his increasing control over Vegeta, Baby forms a face on Vegeta's cheek which continues to speak with him.
- Baby ends up possessing every single person on Earth except for Goku's closest allies, hijacks Vegeta's body as his personal form, and ends up rigging the Earth to blow with the Dragonballs while keeping humanity as his slaves. If not for some last-minute help from Old Kai, Baby would have essentially wrecked the universe.
- The scariest part? The Tuffles made multiple parasites and scattered them about the universe, and Baby was just the one to wake up and head after the Saiyans. In other words, while the heroes threw all that effort into killing Baby, there are more waiting out there in space somewhere.
- Goku's transformation into a Golden Great Ape is equal parts awesome and terrifying. When Goku painfully convulses and morphs to become an Oozaru he loses all control of himself, and now he's a Super Saiyan version of a Great Ape with his power magnified to be more powerful than the Super Saiyan 3 transformation. Even worse is that it's implied this is the form said to be the Legendary Super Saiyan spoken of in Saiyan lore, existing solely for destruction and slaughter until a Saiyan turns back to normal. If not for Pan, Goku might have just destroyed the Earth and killed everyone in sight!
- Shenron's Evil Counterpart. Just when it seems like all the character's problems can be fixed once again by the Dragon Balls, they see a dark, menacing version of Shenron who promises that things will get worse before they get better. The Dragon then unleashes seven demonic evil dragons across the world to destroy it, leaving the heroes without the eponymous Reset Button to fix the world this time.
- Omega Shenron's 'Dragon Thunder' attack. He impales Vegeta on multiple spikes from his back in an incredibly painful manner, then electrocutes him. Yikes...
