Barnacle Boy

Barnacle Boy is Mermaid Man's sidekick. He is voiced by Emmy Award-winning comedian and actor, Tim Conway.

Barnacle Boy (actual name Kyle Stangler) is a 68-year old (revealed in Mermaid Man and Barnacle Boy V) semi-retired superhero sidekick of Mermaid Man, although he still is more sane and aware than Mermaid Man. He, along with Mermaid Man, are the only real humans to appear multiple times on the show (excluding Patchy the Pirate and other characters appearing in his segments). His costume is a cross between the Silver Age Aqualad and Gilligan of Gilligan's Island. Barnacle Boy 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 forming a groop called E.V.I L (Every Villain Is Lemons) 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 with Mermaid Man and the "International Justice League of Super Acquaintances, whose costumes and powers are assumed by the main characters of the show, he and Mermaid Man patch things up. 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).

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.

Barnacle Boy is thin, bald and has large nose like Squidward's, and wears a white sailor cap, a black mask and a blue cape. He also wears a dark blue rubber gloves and boots and a red shirt and rubber black shorts.
