* ''Manga/TwentiethCenturyBoys'': Both versions of [[BigBad Friend]] are absolute monsters of different varieties.
** In the original manga, the first Friend--[[DarkMessiah Fukubei Hattori]]--grew up ignored by his classmates, with their attention often focused on hero Kenji Endō. Thus, Fukubei developed a [[AttentionWhore craving for attention]], and a [[DisproportionateRetribution disproportionate hatred for Kenji]]. Already [[KidsAreCruel wicked as a child]], Fukubei psychologically abused his so-called "best friends," regularly tried to terrify people with his tricks, and ruined the childhood of one of his classmates--who would later become the second Friend thanks in part to the Fukubei's cruelty. Forming the "[[{{Cult}} Friendship Party]]" as an adult, Fukubei began developing a virus that painfully killed anyone it infected, all while silencing anyone who got his way. Unleashing the virus, Fukubei framed Kenji and his group for the ensuing 150,000 deaths, took over much of the world as a "hero", and ruled it with an iron fist, sending people to reeducation camps for even minor crimes. Fukubei's master plan is then revealed: Use a new virus to wipe out 99% of the human race, then rule over the remaining 1% of "true believers". Sociopathic, egomanical, and petty, Fukubei Hattori set the bar for wickedness in this manga.
** The second Friend--[[FromNobodyToNightmare Katsumata]]--[[StartOfDarkness grew up unliked and bullied]], in particular by Fukubei, and this resulted in [[StrawNihilist a hatred for all humanity]]. Taking over after Fukubei's death, Katsumata destroys much of human civilization with a new virus and rules what's left even harsher than Fukubei, spreading tales of "aliens" invading to keep innocents terrified in the process. To further cause chaos, Katsumata regularly sends out small doses of vaccines to groups of potential rebels, knowing they will tear themselves apart trying to acquire the antidote. Revealing he plans to [[OmnicidalManiac destroy all of humanity with an incurable virus]], Katsumata tries to [[ForcedToWatch make Kenji watch]] as he kills Kenji's niece, Kanna--Kanna's mother is Kenji's sister, while her father is Fukubei--as revenge for a transgression Kenji committed against him as a child, and, when finally defeated, it is revealed he left an Anti-Proton bomb to be detonated by his followers, which will destroy the entire world when activated. In the alternate Perfect Edition, Katsumata is revealed to have been both Friends all along, having masqueraded as Fukubei and carried out all the initial atrocities himself.
* ''8.1 Yamada Yuusuke Gekijou'', by Yamada Yuusuke & U.G.E: [[NoNameGiven The unnamed organizer]] is a {{sadist}} who oversees many {{deadly game}}s to enjoy the suffering of his victims and comment about it to his subordinates while he eats.

When Takanobu proves his skills and overcomes all the obstacles, including outright sabotage, the Organizer ignores his victory and decides to start a "second game" to force Takanobu to [[SadisticChoice choose between]] his girlfriend or his own life.

* ''Manga/AcidTown'' has these two [[WouldHurtAChild pedophile rapists]]:
** Ashiei is a member of the {{Yakuza}}, like many characters in this manga, but what distinguishes him is the fact that he raped his stepson Yuki and sold him into being a SexSlave when Yuki was only 12. Years later, he shows up again, stalking his stepson. When a friend of Yuki's tracks him down to confront him, Ashiei brags about his stepson's "talents" as a slave and about raping him. He reveals that he's stalking Yuki out of revenge for [[NeverMyFault being left with burns from a fire that Yuki set to escape him]], because his looks were ruined and he's in pain, [[UngratefulBastard despite the fact that Yuki showed mercy by not killing him.]] When he finds out Yuki is still alive during their confrontation, he gloats about how he wants to rape him again, and tries to do so until Yuki escapes. He was a StalkerWithACrush on Yuki's mother, took the opportunity when her husband died, possibly raped her as well, and was a factor in her [[DrivenToSuicide suicide]].

He reveals himself to be a FalseFriend of Ashiei's, offers Yuki a loaded gun to finish him off, then, when Yuki hesitates, shoots [[AssholeVictim Ashiei]] himself. However, it turns out he was the slaveholder/pimp that bought Yuki from Ashiei. He is an owner/seller of child prostitutes. He didn’t help his former victim out of any noble cause, but instead wants Yuki, now seventeen-years-old, for himself as his personal "pet," as well as using him as TheMole against an opposing mob boss that's actually treating Yuki with some degree of respect and caring. By kidnapping Yuki and holding him hostage, along with his previous actions to consolidate power, he's also managed to turn the heat up on a MobWar that had grown somewhat cold after the first round of deaths.
