* [[Characters/BleachSosukeAizen Sōsuke Aizen]] is a sociopathic {{Ubermensch}} with [[GodhoodSeeker a desire for godhood]] who considers himself above the notions of morality and decency adopted by "lesser beings." Uncaring for anyone but himself, Aizen has a habit of using and betraying anyone close to him. Examples of this include [[MadScientist testing out an experiment]] by turning his former captain, Shinji Hirako, into a monstrous abomination along with seven other Shinigami officers, trying to kill his subordinate Harribel once she had outlived her usefulness, and impaling his devoutly loyal lieutenant, Momo Hinamori, while hugging her, leaving her traumatized for months. Later, Aizen would outdo himself by [[MasterOfIllusion creating illusions]] that tricked Momo's best friend, Hitsugaya, into nearly killing her. Aizen also used Wonderweiss Margela as a tool, stripping him of his speech, intelligence, memory retention, and rationality in order to turn him into a PowerNullifier against one man's weapon. Once Wonderweiss had successfully absorbed the flames of this person's weapon, Aizen had arranged it so that Wonderweiss self-destructed, nearly taking out a city with him in the process. Finally, when Aizen had achieved {{Physical God}}hood, he tested out his abilities by calmly walking through a human city, knowing that his powers caused anyone who came into close proximity with him to blow up. In the end Aizen ended up killing over a dozen civilians, and planned on doing the same to [[Characters/BleachIchigoKurosaki Ichigo Kurosaki]]'s human friends just so he could mock Ichigo by hanging up their corpses on display.

** [[Characters/BleachYhwach Yhwach]] is TheEmperor of the [[Characters/BleachVandenreich Vandenreich]], the King of all Quincies, and the GreaterScopeVillain of the entire work. Yhwach attacks the Soul Society, killing numerous Soul Reapers, while personally slaying the Gotei 13's commander Genryusai Yamamoto. It is then revealed Yhwach was responsible for the ''Auswählen'' nine years prior--stealing the power from Quincies he deemed "impure"—for all intents and purposes killing them--to restore his own power, which led to the deaths of Ichigo and Uryu Ishida's mothers. Furthermore, Yhwach maintains his power and life by [[YourSoulIsMine harvesting the souls of those slain in the war]], on both sides. On his second invasion, Yhwach callously uses the ''Auswählen'' on [[BadBoss his elite Sternritter forces]], save his own personal guard, when he deems them useless to the coming battle. Finding the Soul King, Yhwach destroys him, nearly sundering the separate worlds, while not caring about the innocents or even his own soldiers caught up in the destruction. Said soldiers offer their aid to the Shinigami once they understand the extent of Yhwach's threat to existence; this EnemyMine also includes various other factions, demonstrating how dangerous Yhwach is. Absorbing the Soul King's power, Yhwach later uses ''Auswählen'' a third time on his Royal Guard, including his trusted second-in-command Haschwalth, before defeating Ichigo himself, stealing his powers and declaring his intent to bring ruin to Soul Society and the human world, while threatening to kill Ichigo's friends in their happiest moments should they interfere, all to create a world where [[ImmortalityImmorality he won't have to die]]. Brutal, callous and unrelenting in his selfish belief that [[ItsAllAboutMe everything exists to benefit and empower him]], [[AGodAmI Yhwach]] stands as ''Bleach'''s cruelest and most dangerous villain.

%% NOTE 2: A CompleteMonster is an individual character, not a collective. Therefore a faction cannot be listed as one.

* [[Recap/BleachSubstituteShinigamiArc "Substitute Shinigami" arc]]: [[MeaningfulName Shrieker]] was a sadistic SerialKiller in life who died shortly after murdering a woman named Shibata when, while he was walking to land the final stab, her infant son Youichi grabbed his shoelaces, causing him to fall out of a window. [[WouldHurtAChild Stealing Youichi's soul]] and putting it inside of a parakeet, the [[Characters/BleachHollows Hollowfied]] Shrieker promises that if Youichi can escape him for three months at a time, he'll bring the child's mother back to life--[[ILied something he can't do]]. Able to track Youichi's soul, Shrieker kills and devours anybody who tries to help Youichi, feeding off the psychological torment it causes, as much as the actual souls.
* [[Recap/BleachHuecoMundoArc "Hueco Mundo" arc]] & [[Recap/BleachHowlFromTheJawsOfHellArc "Howl From the Jaws of Hell" arc]]: [[EvilutionaryBiologist Szayelaporro Granz]] is the [[Characters/BleachEspadas6To10 Octava Espada]]. When he was human, Granz was an unhinged alchemist who performed torturous experiments on prisoners captured by his brother. A sadistic player of games, Granz creates {{voodoo doll}}s out of his victims, and then proceeds to torture them to death, rupturing one organ at a time, as he cheerfully does to Renji Abarai and Uryu Ishida. He's also the [[BadBoss worst boss]] of any of the Espada, modifying the bodies of his subordinates so that in a pinch he can convert them to raw energy and devour them with ease, using their lives to fuel his own. A sickening scientist, who [[SmugSnake regards himself as the ultimate life form]], Granz takes pride in his unique brand of depravity, and regards everyone, including his late brother Ylfordt Granz, as beneath him, and, ultimately, disposable.

* [[Recap/BleachNewCaptainArc "New Captain" arc]]: [[FauxAffablyEvil Gyōkaku Kumoi]] is the traitorous and seemingly kind stewart of the Kasumioji Clan who aims to take it over. Plotting to kill the clan's heir Rurichiyo Kasumioji--[[WouldHurtAChild a mere child]]--Kumoi sends multiple assassins after her. To advance research on the [[EvilWeapon Bakkōtō swords]]--forbidden weapons that gradually [[HungryWeapon eat its user's mind]] until death ensues--Kumoi uses several human subjects, with several dying as a result. When Shin'etsu Kisaragi investigates Kumoi, the latter discovers him, forcibly gives him a Bakkōtō, brainwashes him with it, and forces him to go kill the one who sent him, Genryusai Yamamoto. When cornered by Ichigo and his allies, Kumoi has no problem using Rurichiyo as a {{hostage|Situation}} before trying to kill her.
