First appearance of the evil wizard Gemini. He will appear again in the second season episode "Last Train to Doomsday" and will be the only villain of the series to make a return appearance.
The World Trade Center was destroyed in 2001, seven years after the apocalypse happens in Thundarr, so its appearance is not an anachronism.
First episode produced for the series. A number of scenes from this episode appear in the opening title sequence used throughout the series.
The setting for this episode is the ruins of Manhattan which has been renamed "Manhat".
The "Moo-vie" poster seen in the subway station is for "Jaw-9".
