Mermaid Man is a semi-retired superhero. His name is a portmanteau of mermaid and the lesser-known merman, the later being the actual name for the male version of a mermaid.

Mermaid Man is a semi-retired superhero who has aged well past his prime. His costume mostly resembles the costume of the comic book hero Aquaman, with the addition of a star-shaped mask, a scallop-shell bra, and a pair of fuzzy slippers. Mermaid Man's underwater lair and method of crime fighting is a parody of Batman, and his "Invisible Boat Mobile" is a parody of both the Bat Mobile and Wonder Woman's invisible jet. It is unknown how he can live in Bikini Bottom, as he, along with Barnacle Boy, are the only true humanoid characters on the show (although he could be Atlantis or otherwise super-powered). He has an obsession with the word "Evil!” Mermaidman was usually thin and strong 30 years ago. However, now that he is retired, he is enormously fat. He may also be a parody of Mario, the gaming character.

His sidekick is Barnacle Boy, who he treats like a child although he is 68. Mermaidman appears to be in the advanced stages of senility, often forgetting what he was talking about, or what he was doing. This is not a problem for SpongeBob and Patrick, who unconditionally adore the two heroes and managed to coax them out of retirement and back into television. SpongeBob has appeared with them in eight different shorts — often involving a super villain, a Super Gadget, or some combination of the two. In one episode, he and Patrick made a film about the heroes.

Mermaid Man has several nemeses that he fought long ago. The Dirty Bubble, a being made from dirty bubble soap, Man Ray, a humanoid stingray who does evil things and was frozen in the Mermalair, Atomic Flounder, a fish who can shoot nuclear blasts from his mouth, and the Moth, a humanoid moth who steals light and according to Mermaid Man, he has been searching for the Moth for 57 years. The reason it was 57 years was because the Moth is really small, and imagine trying to search the same moth!


Mermaid Man and Barnacle Boy in Shuffleboarding

Mermaid Man enjoys watching television and playing checkers with Barnacle Boy. He eats almost anything. His favorite foods are meatloaf, mashed potatoes, broccoli, Krabby Patties and ice cream.

According to Mermaid Man, his powers are all in his costume. He uses abilities similar to Aquaman's such as: summoning and controlling sea creatures, high speed swimming (used to create an effect dubbed the Raging Whirlpool), water balls, and the ability to survive underwater. While Mermaid Man retains all of these abilities, they are not as powerful as they were in his prime.

In addition to this, Mermaid Man's Belt is a wide array of various weapons, most commonly seen as some kind of beam or ray. The only one named is the Shrink Ray which shrinks things, but various effects were created when SpongeBob used the belt on Squidward trying to reverse the Shrink Ray's effects. His belt features other powers such as Building Obliteration Button, Chin Cam, and various radioactive beams that cause bizarre mutations and various effects to the subject, such as causing them to suddenly catch on fire, turn inside out, or to be cut in half by scissors. They are only briefly shown, all afflicting Squidward. This seems to be a reference to both Batman and Space Ghost. In the Episode: Shuffleboarding, it is also revealed that Mermaid Man has a Secret Weapon that is similar to a Bumerang called the Mermerang.
