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, with an IQ of 150, and loves technology. Sometimes she gets engrossed with technology, and her enthusiasm with the same can be irritating. She is self-confident and a perfectionist. 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 selfless and nice to them; she truly cares for them, even if she cannot always show it using emotions. She develops emotionally through the series and eventually experiences crying, stating that she never cried before. In Season 3 , she even decides to give up her emotions and love to acquire the Water Stars needed to defeat Valtor.

Her Enchantix outfit, in extreme contrast to that of her Winx outfit, is considerably more "revealing". Primarily violet in color, Tecna's outfit also consists offlattering light blue translucent above-the-elbow gloves that are decorated with various violet colored jewels and orchid, light yellow and violet, ample butterfly-styled wings, now instead of a glider, with violet bejeweled outlining. Her wings have spurs/tails with spiral tips. Her hind wings are seldom apparent in the show. She wears an orchid tube top with orchid shorts. On top of the tube top, there are two light blue petal-shaped ornaments connected to several more petal-shaped ornaments on the sides of her shorts. She is the only one of the Winx girls, besides Bloom, it seems not to have her hair styled in curled bunches and ponytails; while it has not grown in extreme length like the other Winx girls, it does lengthen at least a few inches in the back, below her neck, like a flowing fountain, earning her a sassy, tapered and sophisticated look and style. She has also discarded her powder blue colored boots and dons strappy green barefoot sandals with purple jewels, and wears (instead of a tiara as the other Winx girls do, except for Bloom) what appears to be a lily-shaped, soft green colored barrette clip placed upon the left side of her head. Her fairy dust vial is violet with a hole in the middle and diamond top.
Tecna's Believix outfit is vaguely reminiscent of her old Winx outfit; a short-sleeved, form-fitting outfit of sorts with peach extensions on her arms, three sections cut out of her sleeves like stripes, the top half being lavender while the bottom in more violet and shaped like hot pants with a neon green chord wrapped across her right breast area and a matching, blue-studded belt around her waist. Wrist-length, fingerless violet biker gloves are on her hands, below-the-knee lavender stockings, and a pair of indigo and white lace-up, ankle-length platform boots with lilac-white heels. Lastly, her wings are lined in purple and fade from the middle to the tips in rose pink, chartreuse, and neon green with purple drop decorations and long purple twists at the bottom of the wings. Her hair tapers to a point, giving her a sophisticated look, similar to Enchantix, and she now wears pale lavender eyeshadow. She does not seem to really have hind wings in this form, just purple frames of would-be wings.
