Pierre Jeunet is a supporting character in the Sugar Bunnies anime, appearing across the original series, Sugar Bunnies Chocolate!, and Sugar Bunnies Fleur, as well as in related specials. He is depicted as a teenage boy with blue eyes and brown hair cut to neck length, and he belongs to the human cast of the story.

Pierre is introduced as one of the close friends of Sophia, the human girl connected to the bunnies' adventures in the human world. His most distinctive trait is his skill as a biker; he is described as an expert motorcyclist who sometimes goes on riding tours across Europe. This activity speaks to an active and independent side of his character, and it gives him a role as someone comfortable with travel and the wider world beyond the local setting.

Because of his friendship with Sophia, Pierre becomes one of the people who learns that the Sugarbunnies are real. He is therefore part of the small group of human characters who are aware of the bunnies' true nature, which places him in a position of trust within the story. His presence in the series is that of a reliable companion rather than a leading figure; he supports the main events through his connection to Sophia and his knowledge of the secret.

The story does not explore Pierre's personal background, ambitions, or emotional growth in depth. His motivations are primarily tied to his friendship, and he functions as a steady, supportive presence across the different series and specials in which he appears. His notable ability remains his expertise as a biker, which distinguishes him among the human characters and enables his cross-country tours.
