List of episodes

"Catalysts" is the seventh episode of the animated television series The Spectacular Spider-Man, which is based on the comic book character Spider-Man, created by Stan Lee and Steve Ditko. The episode sees Spider-Man trying to stop the psychotic supervillain Green Goblin from bombing a dinner party filled with high-class New York citizens on the night of his school's big Fall Formal.

Written by Andrew Robinson and directed by the series' co-developer Victor Cook, "Catalysts" marked the first appearance of Green Goblin in the series. The villain's design followed the show's color scheme by emphasizing the color green and was based primarily on initial designs by Alex Ross for the character in the 2002 film Spider-Man. Performers Steven Blum and Vanessa Marshall began their roles as Green Goblin and Mary Jane Watson, respectively.

The episode originally broadcast on April 26, 2008, following repeat episodes of "Natural Selection" and "Competition." It is available on both the third volume DVD set for the series, as well as the complete season box set. It ranked as among the highest rated children's telecast the morning it aired and received a generally positive response from television critics. Green Goblin's appearance and new personality split critics, who felt that it was suitable but also strayed from his comic appearance.
