Jenny, Brad, and Tuck can't seem to agree over the rules of a board game. But when the boys tag along on Jenny's mission to a garbage dump asteroid, they run into Vexus, Smytus, and Krackus who are stuck in the asteroid. The ex-Cluster Queen is looking to drain Jenny of her energy, but she and her henchbots can't agree on what to use the power for.
After almost getting hit by a truck, Tuck becomes hyper-paranoid about everything, until Jenny shows himself in the future, perfectly healthy. Tuck realizes that he's not going to die until he lives a full life, and decides to become a daredevil, seeking fame and glory. Unfortunately for Jenny, this means a lot of stopping what she's doing and saving him from his crazy stunts.
If Tuck doesn't pass his next assignment, he's going to wind up repeating the second grade. His assignment: a project on his personal hero. His subject: Jenny. His project: create a movie centering on Jenny's life. His personality: too enthusiastic for anyone to stand. Along with a generous amount of creative license.
With Misty hanging in Tremorton and doing her part in keeping the town safe (though not for free), Jenny decides to leave the superheroics to her and starts to slack off. But when Misty's mercenary habits clash with Jenny's views on protecting the innocent, fisticuffs break out between the two. What's going to become of their friendship?
A group of aliens worship Jenny after she is mistaken for a "comet goddess". It's fun at first but they soon drive Jenny crazy. However, when confronted, the aliens promise to leave her alone after one last ceremony. Jenny unwittingly pulls the Sun towards the Earth, and uses the same ceremony the opposite direction. She then hurls the alien's spaceship into an elliptical orbit around the sun, turning them into a comet. The Earth is saved, but someone's missing...
