Mermaid Man and Barnacle Boy are holding up the line at the Krusty Krab, trying to decide what to order. Finally, Mermaid Man orders a Krabby Patty and a Pipsqueak Patty for Barnacle Boy. Barnacle Boy demands an adult-sized burger, claiming that since he is very old, he should no longer be treated as a child. When Mermaid Man,Squidward, and the Krusty Krab patrons begin to tease him, Barnacle Boy breaks his friendship with Mermaid Man and joins Man Ray and the Dirty Bubbletoformavillainousgroup known as "E.V.I.L." (Every Villain Is Lemons), a group that does immature criminal acts. Mermaid Man cannot defeat this new threat on his own, so he recruits SpongeBob, Patrick, Sandy, and Squidward (who wasn't willing to join) to reform the "International Justice League of Super Acquaintances". SpongeBob becomes the "Quickster", and is able to run at amazing speed. Squidward becomes "Captain Magma", and gains the power to produce fire and lava. Patrick becomes the "Elastic Waistband", and gains the power to stretch his body to incredible lengths. Sandy becomes "Miss Appear", and can become completely invisible. The Chief {which his name is suppose to be John} (a live-action character who appears on a monitor) informs them that E.V.I.L. is at a teenage gathering spot called Makeout Reef, where they are harassing the teenagers by shining a flashlight on their parked cars while they are making out (including a boy who is kissing his own pillow). Mermaid Man and his team go to Makeout Reef and confront the villains, and, despite numerous advantages, the incompetent Super Acquaintances defeat themselves. Squidward accidentally shoots hot lava on SpongeBob's head, and the later starts running around in circles at super-speed as he burns in pain. Patrick tries to stop him from running, but he gets caught onto SpongeBob, and is launched into a rock. Mermaid Man tries to put out SpongeBob, but mistakes Squidward for SpongeBob and washes him up with a water ball, disintegrating him. Sandy disappears in order to catch E.V.I.L. by surprise, but is hit by a boat from behind and knocked off the cliff. By this time, SpongeBob has completely disintegrated, and all that is left of him are his shoes. Mermaid Man simply falls over backwards. Having "defeated" the heroes, Barnacle Boy demands 3 things of Mermaid Man: that he be treated as a superhero, not a sidekick; that he be called "Barnacle Man"; and that he be allowed to eat an adult-sized Krabby Patty. He then immediately rejoins the side of good, though when the heroes return to the Krusty Krab, Barnacle Boy admits an adult-sized Krabby Patty actually is too big for him. Everyone begins laughing as the episode ends, including SpongeBob and his friends, who are severely injured and supported by medical equipment, Man-Ray and the Dirty Bubble, who are in prison, the Chief was kissing his pillow.


  • This is the first and only episode where Barnacle Boy becomes evil.

  • This episode is featured on the Fear of a Krabby Patty and Pet or Pests DVDs.

  • This episode mentioned that Barnacle Boy's real name is Kyle. However in Mermaid Man Begins, his real name was said to be Tim (as a refrence to the actor potraying him). Maybe it's because Mermaid Man forgot his real name, or that Kyle is his nickname.
  • This is the fourth and final time Mermaid man's belt is yellow.
  • Before Barnacle boy decided to come back to the good side he said he wants to be called "Barnacle Man" instead of "Barnacle Boy" but in the next episodes where the heroes showed up, it was fine for him to be called "Barnacle Boy"
  • The Krusty Krab is never half-dark except for in this episode.
  • This is the first time Sandy gets severly injured.
  • This is often considered the best of the Mermaid Man and Barnacle Boy episodes because of a twist in Mermaid Man and Barnacle Boy's relationship, many good jokes like the fish making out with a pillow, and the superhero portrayals.
  • It's strange that Mermaid Man would treat Barnacle Boy like a baby, since they first met when Barnacle Boy was between his teens and young adulthood.
