Biography
Through "Mermaidman Begins," it seems that Barnacle Boy was a normal human who used to be a sailor boy that would scrape barnacles off the sides of ships. That sailor job also gained his name of "Barnacle Boy."
Barnacle Boy is thin, bald, has large nose similar to and bigger than Squidward's, has puffy ears, a black mask and a turquoise neckerchief. He also wears dark blue rubber gloves, boots, a red T-shirt, and rubber black shorts. Being younger, he is more sane and self-aware than Mermaid Man. However, Barnacle Boy is also more cranky and rude. He often calls Mermaid Man an "old coot". He is revealed to be 68 years old in Mermaid Man and Barnacleboy V. As his younger self, he wears glasses instead of a black mask and is much taller.
Barnacle Boy possesses powers similar to Mermaid Man, though he lacks the powers of the utility belt. Barnacle Boy also has "Sulfur Vision" (a form of heat vision), which Mermaid Man has never displayed. Like Mermaid Man, his powers do not work as well as they used to.
Despite being a senior citizen, Barnacle Boy is still treated like a child by his mentor, much to his disdain. In "Mermaid Man and Barnacle Boy V", when Mermaid Man orders a Pipsqueak Patty (a very small version of a Krabby Patty intended for children) for Barnacle Boy at the Krusty Krab, they get into an argument which ultimately results in Barnacle Boy becoming a villain and forming a group called "E.V.I.L." (Every Villain Is Lemons) with Man Ray and the Dirty Bubble. After a protracted fight with Mermaid Man and the "International Justice League of Super Acquaintances (whose costumes and powers are assumed by the main characters of the show), which E.V.I.L. actually wins, he and Mermaid Man patch things up (at this time Mermaid Man reveals his real name is Kyle). Barnacle Man, as he likes to be called, gets a little more respect now (even though he mentions that an adult-sized Krabby Patty actually is too big for him).
