** Furthermore, [[spoiler:Todd Alquist]] extinguishes any light-heartedness left in the series with his [[spoiler:on-screen murder of a child, an event which creates a permanent rift between Walter and Jesse, who [[MyGodWhatHaveIDone had just been working alongside him.]]]]
** Lastly, his uncle [[TheHeavy Jack Welker]] is much more of a CompleteMonster as unlike Todd, he doesn't brutally kill out of ignorance of understanding, but for sick pleasure. He then crosses the MoralEventHorizon UptoEleven when he [[spoiler:kills Hank Schrader and though he entertained Walt's pleas not to beforehand, he never intended to let Hank live]].
* Game of Thrones: Ramsay Snow proves to be the most shocking villain the show's ever had as his actions, unlike the actions of other villains, are committed for the purpose of a sick, twisted form of pleasure.
* ''Franchise/PowerRangers''' BigBad is always either this or a LargeHam. It's not unheard of for them to be both, but it's rather rare. Some examples:

* Scorpius, in ''Series/{{Farscape}}''. Within a few episodes, he tortures Crichton and usurps the role of BigBad from Crais.

* ''AshesToAshes'' has two fairly spooky but ultimately ineffective villains in season one's Clown (who is more a mental/emotional villain for Alex than a true threat) and season two's [[spoiler: Martin Summers, who doesn't directly hurt anyone]]. That changes in season three, when [[{{Satan}} Jim Keats]] is brought in.

** Gus Fring, introduced in second season, is arguably the central example, a DangerouslyGenreSavvy DiabolicalMastermind whose [[TheStoic composure and meticulousness]] makes him a polar opposite of LargeHam StarterVillain Tuco Salamanca. It takes another two seasons for the full extent of his ruthlessness to surface, [[spoiler: as he [[WouldHurtAChild threatens Walter's whole family]] as a deterrent.]] Without giving too much away, a lot of things could never be the same again after his introduction.

** And that spilled over for her appearance in the spin-off ''Series/SamAndCat'', which upped her actions to [[Film/TheSilenceOfTheLambs Hannibal]] levels.

** This trope is somewhat inverted with the Nerd Trio in Season 6. Season 6 is the darkest season as many bad things happen to the protagonists, but when the Trio are around, despite being the villains of the season they seem to lighten the story up with their comic relief and pop culture references. Although Warren soon proves to be just as evil as the previous BigBads of the series, if not more.

** [[ProfessionalKiller The Cousins]] are [[TheStoic emotionless]] and [[ImplacableMan brutally determined]] mass-murderers, who [[spoiler:cripple, and nearly kill, HeroAntagonist Hank Schrader,]] an act with visible consequences for the rest of the series.

* In ''Series/KamenRiderRyuki'', Takashi Asakura/Kamen Rider Ouja was the embodiment of this trope (formerly he was a serial killer). The Rider War consisted of thirteen riders fighting each orher to the death for a single wish [[spoiler: that the real big bad planned to exploit for himself]] and it wasn't exactly puppies and sunshine, but before Asakura came on the scene, only one Rider - a clearly evil one, at that - had died, and the current 5 at that time weren't doing all that good a job at the whole killing each other thing. That changed once he became Ouja, and he's responsible for the bulk of the dead Riders. His first kill was Kamen Rider Gai/Jun Shibaura who was an AssholeVictim at best. The worst part came where on an attempt to kill Shinji/Ryuki, he killed off Kamen Rider Raia/Miyuki Tezuka, who along with Shinji were the nicest and actual heroic Rider OF THE SHOW. His third victim was Kamen Rider Imperer/Mitsuru Sano, who was tricked by Kamen Rider Tiger to attack Shinji, who (Tiger) literally STABBED HIM IN THE BACK, AFTER ACTING LIKE he was his friend, leaving him barely alive. Asakura found him (Imperer) and killed him just because his (Imperer's) Mirror Monster interrupted his revenge match against Tiger. (The worst part about this is that Sano had one of the worst [[DarkAndTroubledPast tragic backstories in Kamen Rider history]], and Ouja killed for just interrupting a fight. His last victim was his rival Kamen Rider Zolda/Kitoka who was an Anti-Hero at best [[spoiler: though it was revealed that Kitoka died due to his cancer, so his butler fought in his place]].
** His American counterpart in ''Series/KamenRiderDragonKnight'', Kamen Rider Strike/James Trademore/JTC was almost just as bad, minus the serial killer part, he was originally a hacker. As Strike, he had a few cameos, ultimately revealed to be Xaviax's [[TheDragon dragon]]. When he first stepped into the action, he SERIAL-KILLER chased Kamen Rider Torque/Drew throughout the city for [[TheStarscream attempting to betray Xaviax]] (it's unsure if he wanted to overthrow Xaviax/have a HeelFaceTurn/or [[YouHaveOutlivedYourUsefulness outlived his usefulness]]) with a [[CoolBike badass Advent Bike]]. When he caught up with Drew, the two fought at the same time Dragon Knight, Wing Knight, and Sting were fighting Kamen Rider Thrust/Brad Barett to convince him to join their side, [[ClearMyName since Brad was a good guy, (compared to his Japanese counterpart) was framed by Xaviax for sabotaging another motor cross racer's bike]]. Knocking Strike down, Drew decided to use his [[AlphaStrike ridicously powerful Final Vent]], which hit all five present riders. No one got vented, but Thrust was severely hurt since Strike used him as a shield. Strike/JTC, knowing that Thrust was GoodAllAlong, and would eventually perform a HeelFaceTurn, vented him. He caught with Drew again and in a epic battle, he was able to vent him. Five episodes later, he and the Cho Brothers [[CurbStompBattle effortlessly defeat Wing Knight and Sting]] and vent Sting when the latter [[HeroicSacrifice sacrifices]] himself to save Wing Knight. In the next two episodes, he kidnaps Kit's dad from the hospital to convince Kit to join Xaviax, vents Axe for disobeying Xaviax when he went after Kit/Dragon Knight for venting his brother, and 3/4 into the series, vents Len's girlfriend Kase/Kamen Rider Siren. JTC actually managed to vent more riders than his counterpart could kill. This guy only gets taken down when, [[spoiler: Len uses the Survive card to transform into his Badass SuperMode, Survive Mode Kamen Rider Wing Knight, brutally combines a CurbStompBattle, RoaringRampageOfRevenge, and a awesome SingleStrokeBattle like clash of Strike's Sting Final Vent and a variation of Survive Wing Knight's Final Vent. It took that much to vent him.]]

* Scorpius, in ''Series/{{Farscape}}''. Within a few episodes he tortures the main character, kills his love interest and usurps the previous villain.

** Also a case of CrouchingMoronHiddenBadass. At first he seemed comedic, with the doll on his arm and messing with it being his BerserkButton, and it would always move while offscreen. While a MadScientist, he was under Kougami's thumb, and was the ''only'' one who thought his working with TheStarscream Kazari was actually a secret. ''Nobody'' could have forseen that Creepy Doll Guy was going to turn the tables on everyone and become a dark and deadly villain and shoot past Kazari and BigBadWannabe Uva to the top of the heap.

* Dave Karofsky from ''Series/{{Glee}}''. The show's antagonist is usually Sue Sylvester and her RefugeInAudacity antics, but Dave, in addition to tormenting the glee club with [[ThoseTwoBadGuys his buddy Azimio]], had a special hatred for CampGay Kurt. At first it just seemed like homophobic bullying, until Dave forcibly kissed Kurt. From there, his {{gayngst}} became a central plot point, going as far as threatening to kill Kurt if he said anything, forcing Kurt to temporarily transfer schools. Even after Dave's HeelFaceTurn, he himself transferred schools when rumors started flying that he might be gay, and it all goes to hell when a boy at his new school sees him professing his love for Kurt at a party and outs him at school, causing ''him'' [[HoistByHisOwnPetard to be ruthlessly bullied]] until he attempts suicide.

* In the Season 5 episode of Series/TheFreshPrinceOfBelAir entitled "Bullets Over Bel-Air," a nameless armed thief held Carlton and Will at gunpoint while they were at an ATM machine. He shot Will after he [[TookTheBullet took the bullet]] for Carlton and runs away. Because of his actions, it lead to Carlton buying himself a gun as an attempt to protect himself and his family members and to the biggest TearJerker in the show in which Will ''begged'' Carlton to give him the gun when he was visiting him in the hospital.

* ''KamenRiderOOO'' is a goofy series about a [[TheDrifter homeless man]] fighting greed, but it soon got crazy when we meet Dr. Maki, learn his backstory, and find out about the [[ForbiddenTechnique purple medallions]]. Before Maki's appearance, there were legitimate villains, but the episodes were still StrictlyFormula, and Maki is soon elevated to BigBad status.

*** Not to mention ''why'' he did all these things. He needed Deker the way he eventually became, and the [[PoweredByAForsakenChild suffering his Nighloks caused as raw material]]; it's all part of TheLongGame to do in one stroke what Xandred and company were trying to do one monster at a time and he nearly succeeded. He didn't do what he did ForTheEvulz; he's quite a MagnificentBastard. And even once he was gone, the consequences of what he did to Deker and Dayu only got darker. [[spoiler: In the end, since Dayu's grief over Deker's FinalDeath is what allowed the injured Xandred to restore himself ''and'' become immune to the sealing symbol, Xandred going from OrcusOnHisThrone to the real menace he was in the finale is also courtesy of Serrator.]]
