* Tao Pai Pai, the most evil villain in ''Dragon Ball'', certainly is NightmareFuel. Especially considering he is the most feared man on the planet Earth. In addition, he is a sadistic mercenary who is even willing to kill children.
** The most chilling in Tao is the fact that he is '''completely human'''. He is not an alien (like Frieza, Vegeta or Babidi) or born for being evil (as King Piccolo, the androids or Majin Buu), he is human and evil by choice, and therefore, he is completely aware of the suffering of others.
** The scene where he kills General Blue is somewhat disturbing, too, [[note]] He does it with his tongue [[/note]]
** Then in Dragon Ball Z, Tien Shin Han has a flashback where Tao enjoyed mistreating him '''as a child''' when he was training, hinting how cruel he was, even if we talk about a flashback.
* So you're watching the last few moments of Goku's fight with Piccolo, all is right, Goku gives a thumbs up to all his friends as they shout the countdown. Right when they get to nine, Piccolo gets up and fires a mouth beam straight into Goku's right shoulder. And this isn't Z where a direct hit from a beam causes some external wounds, and maybe torn clothes or something like that. No. This is Dragon Ball and Goku now has a hole he can stick his hand into under his shoulder. After writhing in pain for a while, Piccolo gets up and begins stomping on the wound over and over as Goku grabs the ground in pain. All the while, Piccolo is grinning ear to ear, and even laughing. Tenshinhan, Yamcha and Krillin try to help but Piccolo stops them before they can enter the ring. Goku, the badass, still manages to get up and get in an attack before a swift kick from Junior reminds him he has a giant hole in his body. Junior, the prick, then elbows Goku, right in the wound, followed by more blood curdling screams. And just to add injury to injury, Piccolo breaks Goku's leg.
** Speaking of Piccolo, the original Demon King manages to give a NoHoldsBarredBeatdown to Goku so badly that it stopped his heart.
* Freeza throughout the entire fight with him. Starting with impaling Krillin and torturing him and then trying to crush Gohan's head slowly in his 2nd form, followed by a NoHoldsBarredBeatdown inflicted on Vegeta designed solely to make him suffer and then impaling him through the chest and watching as he bleeds out as well as just how terrifying he is when it turns out Goku can't even hurt him a little once Freeza powers up just a little and how easily he knocks Goku around.
** Before then, when Frieza shows up after the Grand Elder dies rendering the Dragon Balls useless. Frieza just stands there for a few seconds before he smiles. You knew then that Vegata, Gohan, Krillin, and survivors on the planet are screwed.
-->'''Frieza''': It won't hurt long, relax, death is my speciality.
* Cell is even more terrifying then Freeza, he can kill a human instantly by impaling them with his tail and kills at least six thousand innocent people and you even get to hear their screams as he powers up in his first form. His obsession with absorbing Androids 17 and 18 is terrifying as well, mostly the reactions that they have when they're being absorbed. He even manages to kill Goku and Future Trunks.
* The {{Fridge Horror}} of being absorb by Majin Buu. You are taken into his body where he feeds off your power and knowledge and use them to kill everyone you know. Worse, you cannot die or do anything to stop him. You are forever trapped in an immortal being who will continue to use your abilities to kill billions.
* Goku becoming an Oozaru right before Bulma, Yamcha, Oolong and Puar's eyes.
