*Téa Gardner, known as Anzu Mazaki in the manga and Japanese anime, is one of Yugi Muto's best friends. Téa does not usually play games with Yugi and his friends, but in the beginning of the anime, she could beat Joey Wheeler in Duel Monsters and was later shown to be more than competent against others. Téa is also very good at dancing and wants to be a professional dancer when she grows up.

In the first series anime, her hair and eyes are of a reddish brown color. Her school uniform color differs; her coat is orange and her tie and skirt are green. In the amusement park episode, she wore a light-green bikini.

In the second series anime, she has brown hair and blue eyes. On occasions she wore the school uniform colored in the same manner as in the manga. Her brown shoulder-length hair is sectioned into two layers, consisting of a darker shade of brown inner layer, with the outer layer of a lighter shade.

During the first season of the anime, her usual outfit is comprised of a yellow shirt, which flows like a skirt at her thighs, with a pink waistcoat over it, and a blue miniskirt. A pair of brown knee-high boots completed her ensemble.

In the second and third season, her clothes consists of a light green sleeveless buttoned shirt with yellow collar, pink and blue bracelets, navy shorts with a light blue belt, white thigh-high socks, and blue strapped platform sandals. Prior to being held captive by the Rare Hunters, she also possessed a light yellow handbag. She also wears a yellow tank-top with the word "SPIRIT" on it (which was removed from the dub) and a red skirt on occasion in the second season.

She also wears another outfit: a yellow tube-top, red choker, light pink shorts, black thigh-high socks, red platform sandals, and a pink jacket. In the fourth and fifth season she wears a black sleeveless shirt that reveals her belly button, a red skirt and a pair of white high-heeled boots. During the trip to Industrial Illusions, she wears a white jacket over a red tank top, a pleated yellow skirt, and tan boots and she also wears the same outfit at the KC Grand Championship.

In the 4th season, she wears a yellow jacket, blue shirt, short shorts, cyan socks and blue and white sneakers. In the 4th episode of said season, she wears a black tank top which slightly covers her belly button, navy short shorts with a gray belt, and yellow wristbands.

In Yu-Gi-Oh! Capsule Monsters, her clothes consists of a dark pink jacket, light green shirt, with a beige and neck tie, an emerald-green skirt and brown boots.

In the second series anime, she is usually shown to be cheering her friends and standing up for what she believes in; it is also shown that she will do anything to help her friends. She plays the role of the strong, down-to-earth, caring, compassionate voice of reason of the group.

She is also shown to feel more affection towards Yugi than the Pharaoh in this series (hinted at during the final Duel, and during the Waking the Dragons arc). She is also shown to get easily jealous, such as when Mai (initially), Rebecca and Vivian flirt with Yugi — sometimes to the point where she has an explosive outburst.

Despite her strong bond of friendship, Téa is not above keeping the others, mainly Joey and Tristan, in line when they get out of control or act foolishly. She often says "I need more female friends", yet she loves them deeply. Because of this, Téa serves as something of a sister-figure to her friends.

Téa uses a Deck full of mostly Fairy cards, but in the Virtual World arc, she played with a Deck mostly made of Spellcasters. Like Mai Valentine, most of her monsters are female-related. She combines her Spell Cards with Monster Cards to boost the overall strength of her monsters and she uses Trap Cards like "Waboku" and "Mirror Force" to protect her monsters from harm. She Duels once in the manga and seven times during the course of the second anime series (four of which were off-screen).*
