How talented at magic each girl is
Icy: She has above average raw power. I see her as being more innovative with her powers and I like to think she created the spells she used instead of learning them from others or from books. All those different ice shapes were her own creation
Darcy: Raw power wise she is actually average. However, she put in the time to improve her powers and abilities. She tends to do things very by the book and focuses on technique. None of her spells are original, but she has perfected a very large variety
Stormy: In terms of raw power she has the most, however she doesn't have the same levels of technique or experience as Icy or Darcy. She relies on strong tornados and lightning strikes, but can't manipulate them very well without lots of focus. She has the most trouble controlling her powers and understanding them because she only got a half year at cloud tower before being expelled. She isn't stupid, she just hasn't had the same educational opportunities
Medical impacts because of powers: I just think it is interesting if characters with magic powers are affected by them in other ways, so that is what this is
Icy: Colder average body temperature, always gets fevers if sick (like she doesn't even have to be that sick, anything small can trigger it), gets overheated easily (so she stays away from sweaters and thick fabrics regardless of the weather), but is more resistant to colder temperatures (especially if transformed into her witch form)
Darcy: her eyes are very sensitive to light, which is why she wears the tinted glasses (other people have also pointed this out), She has really good night vision, I like to think her vision is total garbage during the day but at night it is 20/20, once again when in witch form the light effects her less
Stormy: Because of her powers she has epilepsy (because as my favorite she has to suffer), It affected her more when she was younger and couldn't control her powers as well, however she can still have seizures triggered by suppressing her powers or repressing a strong urge to use them (lightrock was fun), Icy and Darcy are very overprotective of her which she kind of likes and is kind of embarrassed by
Right or left handed: I have very strong opinions on this. Why? I don't know. But I know I am correct. (I'm sure there is some scene where these girls are writing or something, but I did not rewatch to check)
Icy: Left-handed
Darcy: right-handed - very upset by this as a child because she wanted to be special. She had trained herself to be ambidextrous but lost the skill because she stopped practicing it and moved on to practicing magic more.
Stormy: right-handed - no one in winx gives stronger right-handed vibes than this character.
Icy and Darcy definitely did that thing where they told Stormy they were playing hide-and-seek and then just let her sit in a box for 2 hours when they were kids.
It wasn't until years later when she was bragging about her hide-and-seek skills only for Icy and Darcy to start giggling that she realized what happened.
Heights:
Icy: 5'4/162.5cm : She just seems average height to me. Of course she appears taller because of the hair and the heels
Darcy: 5'7/170cm : This one was hard because I imagine her as quite tall, but I don't imagine riven as super tall and there is no way season one Riven would date someone who isn't at least a couple inches shorter than him. He has too big of an ego.
Stormy: 5'0/ 152cm: Stormy is small. I just love the idea of her being short and angry. It's just too funny. If she is not the shortest in the reboot I will scream.
Birthdays:
(Note: in my mind the trix are sisters, but not triplets. I'm sorry there is no way Stormy and Icy are the same age)
Icy: December 13th - Idk she just definitely has a December birthday and 13 felt right. She was not born on a Friday the 13th, but she lies and says she was. No one is going back and doing the math anyway
Darcy: October 4th - She definitely felt like an October Libra to me, so here we are. No reason for the 4, I just felt like it should be an even number for her. she is born ten months after Icy and for the short time they have the same age they have a lot of tension between them
Stormy: May 5th - Despite being my favorite trix (and winx character) and the one I have the most headcanons for I have very few opinions on when Stormy's birthday should be. May 5th is the date listed for all of them in the wiki and the date just felt so wrong for Icy and Darcy so she got to keep it. She is about 19 months younger than Darcy if I am doing the math right. (Because she is clearly the youngest and I will fight anyone on this)

I wrote my first winx club fanfic. (of the trix of course) Check it out if you want. I tried
Darcy is by far my least favorite trix simply because growing up she was my sister's favorite trix. I want to write a fic where she is a jerk to Stormy for this reason alone.
Idk I just headcanon her as being the worst of the trix. Not only to the winx, but to her sisters as well. (But mostly Stormy because she is my favorite) I mean I can just see her as being good at noticing people's insecurities and playing to them.
(But mostly the trix)
No one wanted this...

Darcy (to Icy): Is it obvious that I don't care?
