The Secret Origin of Supernova

Arthur and Buster watch Dark Bunny, then learn of both a comic convention coming to Elwood City and the Might-a-Max Energy Drink, which is endorsed by Dark Bunny. They go to buy costumes, planning to dress up as Dark Bunny and Bionic Bunny for the convention, and Arthur buys the energy drink.

Arthur shows off the energy drink to his friends, but Brain reads the ingredients and informs Arthur that the drink is just sugar, water, and food coloring. Arthur is disappointed, especially after remembering Dark Bunny's "self-imposed code of honor," and throws his drink away, then decides to get rid of all his Dark Bunny stuff.

At Meteor Comix, Arthur and Buster look through a book of super heroes for one to dress up as, and Arthur decides on Manacle. After learning that Manacle-Os are unhealthy, he takes down his Manacle posters.

Arthur looks through the book again, and sees Doodle Dog. After Francine sees Arthur with a Doodle Dog water bottle, she takes him to some kindergartners, who say that Doodle Dog is "for babies." Arthur throws his Doodle Dog water bottle in the garbage.

Arthur asks Freddy K. who his favorite super hero is, and he chooses Jack Kirby, who invented a lot of characters in the 1940s-60s.

After a dream, Arthur chooses to dress up as Supernova. While he initially thinks his costume is silly, D.W. thinks it is cool and wants to be his sidekick. They go to the convention, and Arthur's friends like their costumes as well. Arthur is called to look at some Dark Bunny comics, and he realizes that he doesn't have to buy everything that's sponsored and can still enjoy Dark Bunny.
