** The ''worst'' part? Adler!Master Org ''chose'' to do all of this. Driven mad by jealousy and paranoia, he ''chose'' to forsake his humanity so he can brutally murder his former friends and their infant son. He ''chose'' to try and destroy the biosphere for spite. Everything Adler!Master Org does is because he ''chose'' to do it. Which makes him far more terrifying than villains who were made or ''forced'' to be evil.

* '''Master Org''' (especially the first version to appear in the present day narrative, the formerly kind scientist Dr. Viktor Alder). Just everything about his presence is terrifying. It makes most of the villains from the previous seasons look tame. He's killed Cole's parents as well as some of his minions, attempted to kidnap (and kill) baby Cole, he almost killed Cole's teammates, he's also destroyed the Wild Zords he has caused great destruction to the Animarium... and enjoys every minute of it. There seems to be nothing he won't do in order to gain the upper hand.

** Even his death scenes are terrifying. When he first "dies" in human form, we actually see it on screen (which rarely happens), only for him to wake up. When he dies as an org, we see his face one last time (as seen above) which shows his haunted death stare before he ''explodes'', which leaves behind his blood vessels/nervous system (which then also explode), and finally the Org Heart, [[{{Squick}} which is pretty gruesome in it's own right]]. When the Rangers then use the Jungle Sword to pierce said heart and destroy it (before it can rebuild Master Org's body again), you can briefly see the gross red-and-black innards of said heart.

* Mandilok can also qualify, if because they have multiple mouths and two minds.

* Cole's parents' FamilyUnfriendlyDeath, as shown in flashbacks in ''Wild Force'' was something that [[GettingCrapPastTheRadar shouldn't have gotten past the censors]]. Saying "kill" just won't fly, but having vines assault and grow through the bodies of two terrified humans is hunky-dory so long as no actual blood is shown. Allegedly, writers told Fox standards and practices the parents were going to come back just fine - rumor has it that had it not gotten past the radar, Toxica and Jindrax would have turned out to be the parents (though that doesn't jibe with them having known Master Org from 3,000 years ago and ''immediately'' suspected something wasn't right about the current one, so don't quote us on this one.) The show was in the middle of transferring to Disney's control, and standards and practices folks there did not see earlier episodes and merely assumed they were dead the whole time.

** In addition to being creepy, he also looked creepy too. Everything from his soleless eyes to the haunting stares he gives off can give anyone nightmares.

** [[spoiler:To elaborate on all this before he became such a nightmare: Dr. Viktor Adler was once a respected scientist who worked with Cole's parents Richard and Elizabeth Evans and secretly had a crush on Elizabeth, but after Cole's father proposed to her and took the spotlight during the press conference on their research, Adler became driven by jealousy and sought revenge against them. So what did he do? He took seeds of the original Master Org, causing Master Org to possess his mind and body and kill Cole's parents and would have killed Cole (who was just an infant, by the way) if he had found him.

What makes him even worse is that he is the first ''human'' villain who actually ''chose'' to become evil, all other human villains before were either brainwashed and didn't have control over their actions or had sympathethic qualities (like Ransik). He willingly became the second Master Org so that he could murder two innocent people who saw him as a friend and meant him no harm in the first place (They didn't even know that Adler had a crush on Elizabeth and Richard even encouraged him to speak during the press conference), out of a petty grudge, while claiming that it was his rightful revenge. All these things make him one of the most vile, malevolent villains in Power Rangers universe, with only a handful of villains matching him in terms of evil.]]

* In ''Wild Force'', Toxica was tricked into cutting off her horn, which weakened her to the point of being unable to stand up. Soon after, Mandilok avoided a shot from the Jungle Blaster by using her as a human shield. She disappeared in a cloud of gold glitter and died, despite being the only human-looking org in the season. Mandilok carelessly taunted Toxica as she died screaming in agony.

* '''Master Org'''. Just everything about his presence is terrifying. The idea that this once kind and (formerly) innocent man is capable of such evil, it makes most of the villains from the previous seasons look tame.
