Hope Island

Hope Island

Hope Island is where Gaia resides, and the only place she can exist in a solid form - she is transparent everywhere else.

Hope Island is apparently sustainable - the Planteeers live there between missions, in separate sleeping quarters. There are gardens, and beaches, which the Planeteers are responsible for maintaining - though their duties are usually taken to and seen as hobbies, rather than chores.

The Crystal Chamber on Hope Island is where the Planeteers meet before missions, usually gaining information from Gaia and the Planet Vision screens.

In episodes such as Heat Wave, it is learned that if Hope Island comes under attack and dies, Gaia dies as well.

The exact location of Hope Island is never revealed.
