When three kids explore Charterville's haunted Hillhurst Mansion on a dare, they discover a lot more than they bargain for! The trio find a wild and wacky phasm named Flabber, who changes their lives forever when he grants their wish to become the superheroes they've read about in BeetleBorgs comics. However, not only does Flabber grant the kids' wish, but he also accidentally facilitates the escape of supervillains from the comic books as well! Now it's up to these three newly tapped superheroes - aided by a friendly neighborhood phasm and armed with fantastic powers and awesome vehicles - to save the world from the forces of darkness that threaten the peace and harmony of all mankind.
A boy named Norman Nussbaum arrives in the city to slay a vampire, who goes by the name of Fangula. When the Beetleborgs discover his motive (because he is in a line of Vampire Hunters), they have to save Count Fangula from the child.
Flabber is determined to turn his hideous housemates into healthy hard-bodies. Enter Super-Noxic, Noxic's little brother, who arrives at Hillhurst under the guise of "Hurt-ulese," a pumped up personal trainer.
The author of "Fright Files" thinks that Hillhurst would be a great inspiration for his work and moves in. Meanwhile, Vexor's new power-phaser makes Typhus more powerful and they set off to confront the Beetleborgs.
Wolfgang's recurring daydream of causing a mutiny becomes reality when Wolfie accidentally returns Flabber to the pipe organ where he gets stuck. Vexor and the Magnavors burglarize Art Fortunes' studio and take comics featuring Nukus, a very intelligent creature.
The BeetleBorgs take a beating from Borgslayer and finally escape to Hillhurst where they must rescue Flabber from the organ and Art from the monsters.
