The two of them are like family to me, as we are all born from Deboss-sama. They were lovable subordinates but are failures. If we let them run free, they could become Torin #2. We can afford to ignore Luckyuro, but we must end Candelira.
Moral Event Horizon in Super Sentai.—Chaos talking to Deboss-sama,
- Choujuu Sentai Liveman:
- To explain Great Professor Bias's Moral Event Horizon, it is important to understand how he runs his group, Volt. As of Episode 22, his students are three geniuses from Earth and two aliens, all of whose experiments he urges on with the utmost confidence. The first of the five students to go is the alien Guildos. Right before his death, Guildos realizes that he is not an alien, but a robot. Bias then confirms that not just Guildos, but the other alien, Butchy, were robots created to make the Earth students work harder. Butchy breaks down at this point because he had memories of a happy life that he just learned were completely fake and that his whole life was a lie and, as Butchy starts undergoing a Heel–Face Turn, Bias makes him self-destruct. If you don't consider this Bias's Moral Event Horizon, then there's his motive for everything in the series: He recruited four students from Earth — one of them had already made a Heel–Face Turn by Episode 22 — so he can raise their "scores" to 1000. While at first it seems like this is just him trying to create proteges as smart as him, it turns out that he was doing this so at a given time, he could extract their brains and use them to extend his immortality. After all the care he seemed to show to his students before this was revealed, this is shocking.
- Kenji Tsukigata, who later becomes Doctor Kemp, began his Start of Darkness with one of these at the beginning of the series, when he heartlessly shot at the future Livemen and their friends, Takuji and Mari. Being responsible for the latter two's deaths, it was simply the start of Kemp's spiral into evil.
- Kousoku Sentai Turboranger: Episode 27 is this for Jarmin. She revives Suzunari Bouma, her Monster of the Week, and orders her to kill the Turborangers and she'll revive her Bouma tribe. Suzunari Bouma disguises herself as a human girl and fools Youhei into falling in love with her, but she becomes the mask and refuses to use the controlling spell on him when the time comes. Jarmin takes Suzunari Bouma back to her lair, where she whips Suzunari Bouma and throws some of the beads that Suzunari Bouma's tribesmen are trapped inside to the ground, killing some of them and threatens her. This makes Suzunari Bouma finally use the spell, cue "I Know You're in There Somewhere" Fight between Youhei and Riki while the rest of the rangers find Suzunari Bouma. When Suzunari Bouma stops using the arte, Jarmin kills the rest of Suzunari Bouma's tribesmen, then whips Suzunari Bouma to death. She then makes her monster grow so thet the Turborangers will have to finish her off.
- She already passed it since Episode 19. She revives the two halves of Goukaku Bouma, brothers Hyouma and Enma. Hyouma doesn't want to fight since it'd make Enma die just like in the past, Enma likes to fight. Jarmin wants both of them to combine, so what does she do? Swear friendship with blood with Enma so he could attack Hyouma for being a traitor. Then suddenly for unknown reason, she attacked Enma to coax Hyouma to combine. Enma ends up Taking the Bullet for his brother, forcing Hyouma to combine with him in order to preserve Enma; both end up as mindless monster, forcing the Turborangers to kill them (especially hard for Shunsuke, who had a similar experience).
- Chikyuu Sentai Fiveman:
- One episode has Doldora using her Monster of the Week to create an illusion of the Fivemen's mother in order to set a trap. Seeing the way Remi holds onto the hope that her mother might be real is enough to send Doldora over.
- Billion gets a sword that makes its user Brainwashed and Crazy, as well as giving them evil powers. He gets one of Gaku's kendo students to use it, preying on the fact that the kid wants to be stronger in order to protect his parents because he knows the Fivemen won't kill the kid.
- Then we have Garoa, after destroying the Fivemen's Humongous Mecha, but not the Fivemen themselves, he decides to draw them out, by attacking their school full of children. The scene with the children running to escape like they're about to die cements it. Shortly before these happens, he has dropped his Butt-Monkey status, if you didn't notice.
- The true villain of the season, Vulgyre, caused Meadow to fall to her death when she refused his offer to rule with him. Accidentally killing Meadow was not his M.E.H., however, as it was a mistake on his part and he sounded genuinely horrified when he saw her fall. His M.E.H. was when he decided to imprison her soul in his body and impersonate her to manipulate the Zone to destroy 1,000 planets just so he could become all-powerful.
- Choujin Sentai Jetman:
- Episode 18, for Radiguet. He loses his memory of being a Vyram after being banished by Juza, and is found by a girl named Saki, who falls in love with him. Saki is terminally sick and has been diagnosed with only six months to live. Radiguet, realizing he has supernatural powers and starting to fall in love with her too, manages to cure her. However, after stumbling upon Juza fighting the Jetmen, he remembers who he is, and wanting revenge, he helps the Jetmen kill Juza. Later, Saki, having witnessed his transformation, tries to persuade him to abandon his evil ways, saying that he must have some good in him since he cured her. While he does consider his options, he ultimately ignores Saki's pleas and kills her, stating that he has no capacity for "ridiculous" things like love.
- If he didn't cross it then, than he definitely crosses it in Episode 49. He kills Maria, after reverting to Rie, in front of Ryū... but not as a punishment for traitors, but just so Ryū wouldn't get the girl he's after.
- Tran officially stops being harmless when he executes his scheme in Episode 36: it involves possessing humans with enchanted ants, to make them devour everything in sight, including livestock. Of course, that episode also marks the last appearance of Tran as a kid; in the end, he ages rapidly into Tranza and continues to one-up his harmful antics with even more dangerous plots.
- Episode 18, for Radiguet. He loses his memory of being a Vyram after being banished by Juza, and is found by a girl named Saki, who falls in love with him. Saki is terminally sick and has been diagnosed with only six months to live. Radiguet, realizing he has supernatural powers and starting to fall in love with her too, manages to cure her. However, after stumbling upon Juza fighting the Jetmen, he remembers who he is, and wanting revenge, he helps the Jetmen kill Juza. Later, Saki, having witnessed his transformation, tries to persuade him to abandon his evil ways, saying that he must have some good in him since he cured her. While he does consider his options, he ultimately ignores Saki's pleas and kills her, stating that he has no capacity for "ridiculous" things like love.
- Gosei Sentai Dairanger
- The Gorma Emperor mostly appeared to be a fairly harmless Cloud Cuckoolander, until he sees Daijinryu's rampage and makes it clear he doesn't care if the dragon kills all humans on Earth as long as he can rule afterwards.
- If Shadam's treatment of Akomaru wasn't enough for this, he definitely crosses with his Evil Plan to become the Gorma Emperor as he doesn't care if his actions bring about Daijinryu's return.
- Denji Sentai Megaranger
- If using children as human shields isn't enough for Guirail, he most certainly crosses it to the point of no redemption in Episode 30, when he uses Yugande, one of his own fellow generals, as a meat shield in an attempt to save his own hide from the Megarangers' Super Galaxy Mega's finisher. Yugande may have barely survived, but still...
- Dr. Hinelar crosses it when he creates the Nezirangers for the sole purpose of killing Javious.
- Technically, he already crossed it as Dr. Samejima when he experimented on his daughter Shizuka, and as a result sacrificed her for the sake of his experiment.
- Shibolena makes it clear that she will never be a good person in Episode 11, when she and her Rose Nezire enact a plan to turn children into carbon copies of said monster of the week. She makes it immensely personal when she forces Ruri, a friend of Chisato, to drink the wine that results in the transformation. And she does this all with a sadistic grin on her face as she preys on a literal child, intent on making her a monster.
- Seijuu Sentai Gingaman: Captain Zahab crossed it before the story began when he killed the original Black Knight's brother and destroyed the planet Taurus.
- Kyūkyū Sentai GoGoV: If banishing Salamandes to Hell isn't enough for Grand Witch Grandiene, then forcing Zylpheeza to shoot the Tatsumi family — knowing fully well and not even caring that Cobolda is in the line of fire — was definitely enough to convince us how purely evil she is.
- Mirai Sentai Timeranger: Gien crosses it by killing Dolnero in cold blood.
- Mahou Sentai Magiranger:
- N Ma crossed it by destroying Magitopia and killing Sungel and Blagel.
- Dagon crossed it by killing Ifrit, and if not then, by killing Titan.
- Meemy crossed it with his betrayal of Magitopia.
- In Engine Sentai Go-onger, Crime Minister Yogoshimacritein crosses the line when he shoots at the Rangers through his sympathetic subordinates, Kitaneidas and Kegalesia, resulting in their deaths. He ended up shooting himself in the foot by doing this, however, as they hang on just long enough to destroy the source of his powers.
- Samurai Sentai Shinkenger:
- In Act 34, the Nanashi attack an elementary school, kidnap the kids that study there, and then they are tricked into piling rocks under the promise that, if the pile is high enough, the children will be allowed to see their parents again. As if that wasn't enough, Akumaro puts some Nanashi there with the little kiddies just to knock their rock piles down over and over again (if you read it all attentively, you'll see that this last part doesn't fall under Arson, Murder, and Jaywalking). Yep, Akumaro's that brand of dick. It gets "better" - the scene is a re-enactment of the afterlife in Japanese folklore. Specifically, the punishment given to stillborn children in purgatory. And you thought it couldn't get worse.
- Being a half-Gedoshu who spends much of his time in his natural human form, Fuwa Juzo is subjected to many What Measure Is a Non-Human? topics, thinking he might make a Heel–Face Turn (he even likes Genta's sushi). His sword Uramasa is made from his family who wanted him to stop being a Blood Knight who lives for nothing else but the sword. Then, when Akumaro tried to use his human emotions to use Uramasa to create a Hell on Earth, Juzo instead cuts Akumaro down and reveals that he prefers to be a full-blooded Gedoshu; he doesn't care one bit for his family's pleas, as all he wants is to use Uramasa to give him the pleasure of killing people.
- Tensou Sentai Goseiger: Buredoran/Brajira barrels over the M.E.H. when he brutally murders Metal Alice of the Agent, right after she helped him bring down Robogog.
- In Kaizoku Sentai Gokaiger, Basco ta Jolokia. Again the twist is that the expected twist of him really being not so bad never happens. Though presented as a traitor and villain who'll stab anyone in the back to get what he wants, he usually has a human face, and he's a lot of fun to watch, and he even has the same gimmick as Daiki Kaito, aka Kamen Rider Diend, who is a textbook Jerk with a Heart of Gold. Okay, so he's not the Sixth Ranger after all like we all assumed, but surely he'll show his former friends some mercy when about to strike the final blow, or realize that there are more meaningful things than serving his own greed, right? Right? Well, surprise: it turns out he truly is an unrepentant traitor who'll stab anyone in the back to get what he wants... including putting a bomb on his cute monkey-beast sidekick Sally and pushing the button, killing him/her instantly, to try to get rid of the Gokaigers, which is the moment that really makes you hate the guy. With this, he proves himself to be the cruelest villain in the series (Compare this to the actual Big Bads, where Warz Gill just wants to prove he's competent, Damaras is a Noble Demon, Barizorg's brainwashed, etc. Would any of them pull something like that?).
- Warz Gill crossed this by ordering a large number of people to be converted into copies of Barizorg. Some say he crossed it earlier when he had strapped a bomb to an Action Commander so that he would take a large city with him. And the only reason why that is because said Action Commander irritated him.
- Zatsurig crossed it long before the story began when he destroyed Ahim's home planet.
- Tokumei Sentai Go-Busters:
- Their plan in Mission 3 pushes Messiah and Enter over this, as the Unwilling Roboticisation and near mass murder committed in the episode was outright said by Enter to be solely For the Evulz.
- In Mission 10, Enter pulls Unwilling Roboticisation on a number of civilians, and then using them as Human Shield.
- In Mission 44, Messiah takes a flying leap past it by assimilating Escape after his revival.
- And in Mission 49, Enter enters irredeemable territory, assimilating an Enetron tank, turning it into a Megazord, along with dozens of innocent employees! And his final plan has him doing this all over the world! As if we needed any more reason for him to be deleted!
- Zyuden Sentai Kyoryuger: Chaos crossed it in Episode 45 when he ordered the deaths of Candellila, Luckyuro, and Aigaron despite just moments before claiming they were like family to him.
- Ressha Sentai ToQger: Zed crossed it when he hijacked and killed Grita, revealing that getting devoured by her was part of his plan. He remorselessly tells Schwarz that she has served her purpose, and then attacked Schwarz as he was grieving.
- Episode 41 pushes him even further over the horizon. He kills Madame Noir in front of her daughter, strikes down Nero and Morc for getting in his way when they were just trying to help him, and then kills Schwartz.
- Doubutsu Sentai Zyuohger: If Ginis destroying 99 planets (including that of one of his own henchmen) wasn't enough for him to cross this, then killing Naria (for her compassion, no less) is.
- Uchu Sentai Kyuranger:
- Scorpio crosses this in Space 16. He manipulates Stinger into believing that he wants to save the universe by killing Don Armage, which leads to Stinger revealing the Kyuranger's plan to find the Argo. Scorpio then attacks Stinger and reveals that the only reason he wants to kill Armage is so he could become Shogun and become ruler of the universe himself. Just to add even more insult to injury, Scorpio taunts Stinger for wanting to believe that he was good person and for how easy it was to trick him. When Stinger asks his brother to kill him, Scorpio coldly complies with his brother's wishes. The only reason he didn't succeed was because Champ rushed in and took the final strike for Stinger.
- Quervo ultimately reveals that he never considered Tsurugi a friend of his, only going with him in order to go down in history as a man that helped kill Don Armage, along with forming a pact with Armage for a second chance in life. In the end, he aided a man willing to kill countless innocents in order to gain power of his own.
- Kaitou Sentai Lupinranger VS Keisatsu Sentai Patranger:
- Dogranio Yaboon clearly crossed this before the series when his reason for stealing the Lupin Collection and killing Arsene Lupin was revealed in #48. His reason? He took it, because he found it interesting to do! And if that didn't convince you, in the same episode he betrays Gauche by taking all of her Collection pieces in order to make the fight more interesting.
- Zamigo Delma seemed to have crossed it when he became the whole reason for the Lupinrangers existing by murdering one of their loved ones each. It turns out their loved ones are still alive (but still frozen), but he is revealed to have gone even further by murdering many humans for their forms to be used as disguises, including the previous Patren 2gou: Satoru Shinonome.
- Kishiryu Sentai Ryusoulger:
- Dragon Minosaur crosses the line by killing Master Blue and Master Pink.
- Tankjo crosses this by deciding to use his seismic energy destroy everything within a huge radius of him.
- Wiserue crosses this by brainwashing children into thinking he's a good guy so they'll act as his Human Shields.
- Gachireus crosses this when he forces Kleon to create 500 Kelpie Minosaurs, in which he forces Kleon to fill two buckets with their essence which clearly exhausts and dehydrates them.
- Mashin Sentai Kiramager:
- Where to begin with when Galza? Not only did he cross it by having his older brother Oradin killed just because he was the king and not him, but he cruelly gloats about it to his niece after Juru exposed him of his chicanery, repeatedly tries to destroy the lad for reminding him too much of his brother, killed at least three members from the same side as his, and attempted to corrupt Takamichi over to his side for the sake of darkness. It eventually gets revealed that Galza Used to Be a Sweet Kid and all of his Kick the Dog moments were because Yodon corrupted him during his childhood.
- Emperor Yodon crossed this years before the series began by corrupting Galza into being evil and working for Yodonheim, telling him to inflict hatred onto his brother and kingdom, due to how the latter and Oradin were presented as potential obstacles to his aspirations.
- Kikai Sentai Zenkaiger: The Tojitendo Dynasty has done this so many times it detracts from the humor the show has been known for, from absolute dictatorships that will execute citizens simply for farting to callously showing no regard for anyone else, treating them as nothing but insignificant insects for them to squash. Between Boccowaus abusing the power of the past Sentai teams, Ijirude kidnapping, pirating, and exploiting Kaito's parents, and Barashitara forcibly conceiving with other women, leaving them to die, and then killing the children from the marriages when they return for their revenge, the Dynasty's crimes completely overshadow pretty much anything that could be considered humorous about its members.
- Ohsama Sentai King-Ohger: Originally, it appeared that Racules crossed it by showing callous disregard to the other kingdoms and even his own subjects. However, it becomes clearer as the series goes on that the true monstrosity for the series was Galactinsect King Dagded Dujardin, a cosmic being who purposefully instigated the war between the Five Kingdoms and the Bognarok SOLELY FOR HIS OWN AMUSEMENT. Apathetic towards everyone but himself and unafraid of being cruel for the sake of it, Dagded's complete disregard for the loss of innocent lives makes him one of the most despicable in the franchise.
- Hikonin Sentai Akibaranger
- Malshina crosses it in 2-10. She cruelly uses General Pain to steal his knowledge on Sentai villains and ultimately turns him into a normal dentist. Next, she brings back Delu-Knight... while making him completely subservient and willing to go through anything for her. Oh, and it's implied all this killed Saburo Hatte and wiped Super Sentai off the face of the earth. Wow...just, wow...
- And, like many things in Akibaranger, this is revealed to be a subversion General Pain is an Author Avatar of Saburo Hatte, who was severely weakened, not killed. Malshina's true plan was to take his place as the most powerful being in Super Sentai.
