Old, retired and foolish superheroes who are adored by Spongebob and Patrick.
Barnacle Boy is Mermaid Man's side-kick. He is voiced by Emmy Award winning comedian and actor Tim Conway.
Barnacle Boy (actual name Kyle) is a 68-year old semi-retired superhero sidekick, although he still is more sane and aware than Mermaid Man. He, along with Mermaid Man, are the only real humanoids on the show. His costume is a cross between the Silver Age Aqualad and Gilligan of Gilligan's Island. Barnacle Boy also exclaims "Mumblin' Morays!" when excited. Although he turned evil and won against Mermaid Man, forcing him to give in to his demand of being called Barnacle Man, he soon reverted to being called Barnacle Boy. Mermaid Man, his mentor, treats him as if he were a young boy, in spite him being an adult. He often calls Mermaid Man an "old coot". In true sidekick fashion he takes the brunt of the physical comedy upon himself.
Barnacle Boy once became a villain briefly in Mermaid Man and Barnacle Boy V, teaming up with Man Ray and the Dirty Bubble following a dispute about a pipsqueak patty (a very small version of a Krabby Patty intended for children) at the Krusty Krab. After a protracted fight — and a painful parody of the International Justice League of Super Acquaintances with the regular cast — he and Mermaid Man patched things up. Barnacle Man, as he likes to be called, gets a little more respect now (even though he cannot finish an adult-sized Krabby Patty). In the same episode, Barnacle Boy mentioned he was so old he had hairs growing out of the wrinkles on his liver spots. He also has a nose similar to Squidward's, although larger.
This is referenced in Mermaid Man and Barnacle Boy IV when Barnacle Boy and Squidward are locked in a battle of wits involving them calling each other "Big-nose." Barnacle Boy also runs security at the Rock Bottom Museum.
In the video game, Battle for Bikini Bottom, it was revealed that Barnacle Boy has a son, a daughter-in-law, and four "screaming" grandchildren.
Barnacle boy possesses powers similar to Mermaid Man, though he lacks the belt powers. However,he does have "Sulfur Vision" (a form of heat vision) that Mermaid Man does not. Like Mermaid Man,his powers are not what they used to be.
