"Why did you let me die?"
Don't let the colorful and pretty scenery of the series fool you, as even a pretty show like this has a surprising slew of horrific moments. Good luck sleeping tonight.- Darcy. Just plain Darcy. She usually sticks to telekinesis, illusions, and hypnosis... But she has also demonstrated Super-Strength, Healing Hands, some strange torture spell that left Musa so traumatized that years after being subjected to it she just froze up when it looked like Darcy was about to cast it again, summoning fire almost impossible to put out, and Combat Tentacles, and that she's Brilliant, but Lazy. What would she do if she ever got the drive she lacks?
- In the episode "Cold Spell", a nightmare monster messes with the Winx's dreams to gain power from their fear. Most of the dreams are pretty tame, but Tecna's features her either having a massive seizure or a violent system failure (depending on whether or not you believe she was a robot). And you get to see this on-screen.
- The 4kids dub makes this episode even more horrifying. While Cine Lume focus more on the psychological horror of the dreams. 4kids goes up to eleven in treating the episode like a Halloween special. The voices that weren't there in the original, the dark more ominous music in the background, and the screams ESPECIALLY TECNA'S (where she looks like she's in a sitaution where she's being trapped and suffocated no less. It's haunting.
- In one episode in the first season, Mirta challenges the Trix on their attitude towards fairies. Darcy's response is to throw a gob of ooze onto Mirta's face, which covers her nose and mouth. In the end, Mirta only gets to live because the spell used to create the blob only lasts a minute; Darcy admits to wanting it to last longer.
- Near the finale of season one, Sky comes across the city of Magix, which was now barren and devoid of life due to the Army of Darkness trampling it underfoot. Sky tries to find any survivors, but to his horror, he catches glimpse of some cocooned people with terrified expressions frozen on their faces. It was apparent what had happened.
- During the season one finale, Bloom and Icy are flying over Magix when Icy blasts Bloom out of the air and into a lake, into which Bloom sinks under the surface. Icy immediately freezes over the water, with the apparent intent of DROWNING her; if Bloom hadn't suddenly manifested the ability to teleport, it's likely that she would have done exactly that.
- In season two, Aisha gets a nightmare of herself in her childhood as the royalty of her castle were lecturing her on how to be a proper princess. More like telling her to just be an idle unassuming person no one notices. Then the servants spasm and all turn into clones of Darkar, who then taunt her that she's always going to be alone.
- In season three, Stormy develops a spell that murders a person with lightning. Icy and Darcy don't believe her, so she follows the Winx to Flora's home planet, where she unleashes the spell on Flora's kid sister, right in front of Flora. To make matters worse, the three of them start laughing maniacally once the spell stops.
- Even if Tecna turns out to be alive later on, her sacrifice is genuinely horrific. First of all, she willingly plunges herself in the dangerous portal that’s going to destroy all of Andros. Despite earning her Enchantix powers, she uses her fairy dust to seal the portal, also sealing herself inside. She lets out a scream and the portal closes in on her. The rest of the Winx begin to scream and cry about Tecna being gone, and it’s a rather bleak end to the episode.
- While Knut himself wasn't too scary in the original version, the recap specials produced by Nickelodeon redesigned him with vampire teeth thrown in, making him a quite bit terrifying to say the least.
- At the end of season one, Light Rock is described as an asylum for the criminally insane, one that has never failed to redeem the inmates. At the start of season two it's shown...and we see how it operates: it exposes the inmates to excessive positive feelings until they become unable to feel anger, sadness or hatred, with the process normally taking one or two months at most (the Trix showing no "progress" after three is noted to be extremely unusual). The Trix are the only ones who resisted long enough to be broken out... And their time there is the reason they remained evil: the sheer trauma from the experience has driven them completely insane, with Icy even vowing to be more evil out of spite.
- In the seventh episode of season five ("The Shimmering Shells"), three of the Winx are subjected to personal nightmares after coming into contact with magical oil. Aisha gets the worst of them, with an illusion of her dead fiancé, Nabu, repeatedly asking her why she let him die. Talk about trauma!
- Near the end of Season 1, the Trix stole Bloom's Dragon's Flame, something said to be impossible. Later seasons showed it is impossible... Except for the Trix, who had figured out how to do it in season 1.
- It is implied that while it's possible to get a piece of the Dragon Flame by force when its keeper is emotionally weak (a result of Bloom discovering she was adopted, Sky lying to her, overall questioning who and what she is), Bloom will always have the power of the Dragon Flame inside her body. This however could delve further into Fridge Horror when you realize that if someone were able to capture her, she'd indeed become an infinite power source... which she did in WOW before being freed.
