The first idea was a Nickelodeon reboot of a show called The Mysterious Cities of Gold (yes that was a real nick show)
The second one is a 007 show where it focused on James Bonds brother Blofeld
and the last one is a new take on Arthur and the Knights of Justice where Merlin took a football team named the knights led by Arthur King sent them back in time and turn them into knights to protect Camelot
Thanks for blocking that user who tired to hurt me.
Since you're working on an alternate version of modern Simpsons, will you consider have Holidays of Future Passed as the series finale (because I heard the episode was originally written as a potential series finale).
