- Rarely gets angry, and when she does it's more in the form of snarkiness/passive-agressiveness. The only way to make her REALLY angry is to steal her gadgets. She'll hunt you down for days.
- Tall lanky stringbean child (5' 10").
- Secretly planning a rebellion against Bloom's leadership because she has the best plans and everyone knows it.
- Bloom didn't believe her at first when she said her hair was naturally magenta. Shades purple, blue and pink/magenta are all natural hair colours for Zenithian people.
- Forms an unlikely friendship with Flora. Tecna hasn't learned to express emotions and has been trained to suppress them so whenever something's really affecting her she gets very stressed out. When this happens she usually goes to Flora for help. Flora sits down with her and lets her talk about her emotions, however confusing, in a safe environment. Then Flora helps her understand what she's feeling and how to deal with it.
- Before her and Timmy started dating, Timmy suggested they start working on different technological projects together, as he wants to spend time with her and it's something they both enjoy. Whenever she wgoes out to do this, Stella teases her and is fully convinced that they're doing anything but science. In reality they literally just build computers and program stuff. Until they start dating, then they not only work on project but also cuddle for a while when they get tired.
- Doesn't tolerate the heat well. She's used to the temperatures in Zenith, which has a really cold climate because low temperatures help the technology function better. Because of this and her pale complexion (another typical Zenithian trait because of low temperatures) she gets sunburnt easily.
- Can appear as cold and blunt as first, but once she learns to express emotions and opens up to you she can be a real sweetheart. She's also really loyal.
- Doesn't give a fuck about your opinion.
- Wore a suit to Bloom's princess ball because she is a non-binary icon and gives zero fucks.
- Demisexual. Up until she opened up to Timmy, she had no idea what being attracted to someone felt like and got rather confused when the other girls talked about it.
- Passive-agressive grammar Nazi.
- Unapologetically beats Timmy at video games. He doesn't mind. Later in their relationship, she sometimes lets him win because she loves seeing how happy he gets.
- She's a cyborg. Technological enhancements are pretty normal in Zenith and her parents wanted to give her an extra edge before she went to Alfea and became a guardian fairy.
- Had a habit of putting her fingers in electrical sockets on purpose and turning them on as a child. As her powers are derived from technology, she's immune to electrocution. It just gives her a bit of an energy boost.
- Doesn't have many friends back on Zenith because she was always introverted and preffered to stay inside and work on her gadgets instead of socialising. There were a couple people that she talked to sometimes at school but she always kept to herself and never got close to anyone. The Winx was her first real group of friends.
- Still has the first robot she made as a kid, Byte, who was like a best friend to her when she was younger, kind of like how a normal child will get attached to a stuffed animal. She keeps him in her wardrobe and sometimes if she's feeling down and is in her room alone she'll take him out and talk to him for a while.
- Her and Timmy's relationship is the most wholesome thing ever.
- They were awkward with each other at first, but as Tecna got more in-touch with her emotions and Timmy got more confident, they became practically inseperable. They have a really strong connection and devotion to each other. As their relationship progresses, they get to know each other so well that they can practically read each other's minds.
