Arthur is dismayed when he learns that the energy drink endorsed by Dark Bunny, his favorite super hero, is unhealthy. He goes in search of a new superhero.

Plot
A narrator starts the show saying that's in the future and Arthur is working as a clerk in a law firm, but when the "signal" appears he becomes "Supernova" and we see Arthur flying and D.W. in a cape (her blankie) and say "Supernova's assistant Starchild", but Arthur said "I don't want help" and Pal as a super dog.

Arthur and Buster are watching Dark Bunny and they found out that there will be a a "Dark Bunny comic invention" next week in Elwood City. Arthur sees Dark Bunny advertise pop as "energy drink" and when they go and buy costumes, he buys the drink.

The next day Brain leads the label and says its sugar. Then after a fantasy daydream, Arthur takes down all the Dark Bunny stuff and tries to find another one superhero. But he finds sugar cereal of one super hero and was made fun of a "little kids" super hero.

Then Arthur has a dream that had him as a "Supernova" and how D.W. and Arthur kind of worked as a team to defeat the snail-villain. The next day he tries to create a costume and D.W. likes it.

D.W. asks if she can be his sidekick and helps with his logo and they go to the convention in Costume and he has learned he can still like Dark Bunny and not buy anything you see on TV.
