Lieutenant junior grade Anthony Brevelle was a male Human Starfleet officer in the 24th century.
In the early 2360s, he was an ensign on the USS Victory. In 2362, he was part of an away team commanded by Susanna Leijten, along with Geordi La Forge, Paul Hickman, and Mendez. They investigated the disappearance of a science team on Tarchannen III, and Brevelle recorded the log. While on the planet, the entire team was unknowingly infected with an alien DNA.
By 2367, Brevelle attained the rank of lieutenant and was transferred to Starbase 112. In 2367, the alien DNA finally affected him. He was compelled to desert his post, stealing a shuttlecraft to return to the planet Tarchannen III. Both Brevelle and Mendez fully transformed into alien creatures, and because their conditions couldn't be reversed, they were left on the planet to live out their days. (TNG: "Identity Crisis")
