Tecna is 16 years old at her first appearance, and her birthday is on December 16. As shown in the series, Tecna is extremely smart and loves technology. Sometimes she gets too into her technology, and her enthusiasm with the same can be annoying. She is always practical and logical, sometimes to a fault. Tecna has trouble expressing her emotions and bases the majority of her decisions on pure logic, though in the second and third season, she gets over that trouble and is more open and friendly toward her friends. She is unselfish and nice to them - she truly cares for them, even if she can't always show it. She loves science, experimenting in her spare time. She also has a photographic memory; as mentioned in the episode Rescue At Cloudtower, season 1. She loves computers and video games. She also has an English accent in the 4kids version and a husky American voice in the RAI version. According to her profile page at winxclub.com, Tecna also enjoys doing sports and being active. She also has a strong bond with Musa. She also really likes Timmy but doesn't know how to tell him. Tecna does not like when Stella bags on her style. However the two of them are pretty close. Tecna helps them all. She is a really loyal friend.
