Tecna, The Techno Faerie

Tecna is extremely smart and loves technology.
On the Winx Club site, her profile states that her favorite color is light blue, her favorite animals are dolphins, that she loves sci-fi films, her favorite music is pop and jazz, and her favorite food is spinach. Her favorite subject at Alfea is Electro-Magic and her favorite spell is Laser Ray.
She is always rational, practical, and logical, sometimes to a fault. Tecna has trouble expressing her emotions and bases the majority of her decisions on pure logic, making her seem cold and unattached. Tecna develops emotionally through the series and eventually experiences crying, stating that she never cried before.
She loves computers and video games, and enjoys sports and being active. She also has a strong bond with Musa (her profile states her as her best friend) and they are roommates at Alfea. Tecna also really likes Timmy, a Specialist, but for a while, didn't know how to express her feelings to him. He was also shy around her.
Of all the girls in the cartoon, Tecna's family and home planet are not fully explored or even seen. Even during the period she was thought dead in season 3, the girls seem to not have met her parents, making her more mysterious than Bloom, who has already solved the mystery of her origins. In the comic, Tecna is a princess with a living mother and father, but that is a different storyline and may not be consistent with the animated series should the subject of her family and culture ever appear.
For a little while, Tecna was the main focus for the Winx Club during season 3. In episode 13, Tecna earned her Enchantix by sacrificing herself to save Andros, using her fairy dust to force her way into the portal and close it from the inside. It was thought that Tecna was dead and she would never return, causing the Winx Club to cry and disband the group. Thankfully, Tecna is found in episode 17, still alive and well. With her back, they were officially the Winx Club again.

Tecna's boyfriend is Timmy, the smartest of the Specialists. During season 2, Tecna was very upset not only by Timmy's showing of cowardice against the Trix, but also about his lack of knowledge about anything other than technology.

Tecna's appointed pixie is Digit, the Pixie of Nanotechnology. She is extremely immaculate, logical, precise, and mathematical, but shows little emotion whatsoever. An obvious match for Tecna, the two seemed to have developed a close relationship with each other. They are often seen playing video games together.
