An episode conceptualized during the show's second season, though no concrete plot had been finalized by the time Invader Zim was cancelled. As a result, many, many, many supposed storylines have circulated about what this episode would have entailed, with many believing this would have served as the Grand Finale.
- Non-Indicative Name: Downplayed, as we only have rumors and a vague outline of the plot to go on, but we still don't know how Dib would fit into the plot, or if he'd invade anything.
- Sequel Episode: To Megadoomer, as the subplot with Invader Tenn and the malfunctioning SIRs would have ended with Tenn captured and the Meekrob and the Irkens at war.
- What Could Have Been: Invader Zim is believed to could have gotten a real series finale in this had the show not been cancelled. Instead, that role would more or less go to Invader Zim: Enter the Florpus almost two decades later.
