Team Atlantis

Team Atlantis is a cancelled animated TV series produced by Disney Television Animation, consisted of three episodes, later released as a complination-movie called "Atlantis: Milo's Return", which was released on home video, in May 20, 2003.

Untitled crossover with Gargoyles episode
One episode of Team Atlantis that was never animated featured an appearance by Demona from Gargoyles. It introduced the hunter known as Fiona Canmore, known friend to Dr. Sweet. The episode would have Demona using the Praying Gargoyle statue to bring Gargoyle statues in Paris alive to kill the local humans.

Scripts and voice recording of the episode can be seen at The Gathering conventions. Marina Sirtis reprises her role as Demona, and Fiona Canmore is voiced by Sheena Easton. Greg Weisman, who wrote the episode, planned to use the story for the Gargoyles comic book series. He said if he is unable to use the Atlantis characters, then he will use analogues for the story.

Greg has mentioned that while the episode itself is canon in the Gargoyles universe, the entire series Team Atlantis is not. In fact, the Team Atlantis interpretations of The Loch Ness Monster and Puck differ from those seen in Gargoyles (notably, the Loch Ness Monster in Gargoyles actually is a surviving Plesiosaur belonging to a colony, like the common depiction).
