 When he impersonates the heroes, he fights Sneero (le méchant), the main antagonist of the series who represents the main villain of the parody universe.Additionally, Walter is sometimes partnered with Amelia, a woman who represents the heroines, token female characters, female sidekicks, and love interests of the story.In the second season in order to make the show educational, Walter and Bitterbug would receive cross-time distress messages from historical figures such as George Washington, Christopher Columbus, Marco Polo, Thomas Edison, Lewis and Clark, Georges Méliès, and the Apollo 11 astronauts, rather than fictional characters, unlike the first season.
