Adonis is a villain from the Teen Titans show. He is a supervillain and an enemy of the Teen Titans.
Adonis first fought the Teen Titans in an animal testing center. Even though he defeated the Titans, Beast Boy was so enraged by him that he viciously attacked Adonis, wreaking his suit. While battling a chemical tank was punctured and drenched both Adonis and Beast Boy with its contents. The chemical was a mutagen that it made Adonis and Beast Boy become more vicious and savage, from their behavior and then later physically by turning them into werewolf-like creatures. He then broke into the Titans Tower to attack Beast Boy; however when Raven came across the scene, he attacked her too and kidnapped her in the process. Unfortunately, Beast Boy, who unleashed his inner animal, managed to track them into the city's sewer system and saved Raven's life. Beast Boy later fought Adonis while they were both in their werewolf forms. When Beast Boy won, Cyborg cured the mutation from both of them and Adonis was sent to prison.
At some point, Adonis returned to harrass and mock body-builders at a beach but was easily defeated by Cyborg. Adonis then joined the Brotherhood of Evil. He participated in a race held by Ding Dong Daddy but was excluded when he was defeated by Red X.
When the Brotherhood executed its plans to eliminate superheroes from the world, Adonis was sent with Atlas to capture Pantha. Even though he and Atlas pinned her down, they were both defeated by Pantha. He was attacked at the Brotherhood's base by Mas, who kicked his foot. While hopping on one leg in pain, Herald blew his horn, which stripped him from his armor. He is later knocked out by a strong kick from Herald. It is not known if he was flash-frozen with the other villains at the end of the final battle.
