Mermaid Man was born November 10, 1940 to unknown parents. At age 15, he had a microwaving accident followed by a series of unfortunate events which led him to become a superhero. He became star of his own TV show until about 2005, when he was deemed "too old." He became a superhero again a little later, but his power has weakened.
Barnacle Boy was born around 1945 to Mermaidman's sister, Merman Woman. He cooperated with Mermaid Man until the show was canceled, and soon became a superhero again, too. However, he was tired of being called "Barnacle Boy," so he joined "Every Villain is Lemons." Then he changed his mind and decided to rejoin as Barnacle Boy.
