History NightmareFuel / KipoAndTheAgeOfWonderbeasts

* The Status of being Half-Mute. Sure you gain all sorts of helpful powers and enhanced strength but there's a pretty horrible catch.[[spoiler:Half-Mutes like Kipo, Song, and later Emilia risk completely losing their personality to the Mute Beast inside them once their powers develop, which will overtake them and keep them as Mute Beasts forever if they lose an anchor which connects to their humanity. Once a Mute Beast, they are effectively mindless and uncontrollable while still having enough degrading human awareness to be trapped inside their own bodies until they die, as Song described while having spent over a decade as the Mega-Mute Monkey. Even creepier is that Song bestowed this horrible fate upon her own daughter and herself through her own experiments, which could have caused Kipo to turn into a Komodo Dragon, Monkey, or something much [[BodyHorror worse]].]]

*** Made worse when Rad Sechrist revealed on his [[https://twitter.com/radsechrist/status/1317233816486903808 Twitter]] that they considered a scene where Fun Gus drags Emilia back to her old bedroom recognizing photos of her and her brother. Fun Gus would then take the shape of her brother as he wanted a 'forever sister' forcing Emilia to confront her past every day.

-->'''Liam:''' What if everything we’ve been taught is wrong? I’m gonna show people what Mutes are really like! This will change everything!\\

'''Emilia:''' ''I can’t let you do that''.

* [[BigBad Dr. Emilia]] in general. She's a no-nonsense MadScientist whose goal is to make a so-called "cure" for Mutes that will devolve them into regular animals, even willing to kill if it means getting her way.

* The mind control of the humans by Scarlemagne. Not only are they forced to perform for his amusement but they are at least somewhat aware of what is happening to them. Every human we see has a look of stress and terror combined with the smiles forced onto their faces. It is downright chilling to see.

* After her final attempt to cure the Mutes fails, Emilia injects the DNA of a Mega-Mute into her bloodstream causing her to transform into a gigantic, four-armed, two-headed, eight-eyed Mega-Mute.

* TheReveal that Emilia ''[[CainAndAbel murdered her own brother]]'' and made everyone believe that he was killed by mutes.

* The state of the world itself. Humanity has mostly been hiding out in underground bunkers for around 200 years, because the Mutes on the surface usually want to KillEmAll. Worse, it's made clear as early as the first episode that the Mutes ''know'' about the burrows and often go looking for them, treating it as a kind of jackpot to find so many humans clustered in one place to kill or eat.

* When Wolf reluctantly agrees to help Margot save her brother, she tells her ex-sister that if she is being led into a trap, she will ''wear her skin next''. Keep in mind Wolf managed to kill Margot’s mother, who is a fully grown wolf mute. Margot is not much older than Wolf, but Wolf still admits she will kill the sibling who wronged her without reluctance.
