The concept that the Builders were creatures formed from steam was originally going to be used for the Peacekeepers, who would have been known as "Steamtroopers," made from animated steam.

Tony Tilse felt that the creation of Kahaynu's face was homage to the way the Mummy's face appears from the sand in the first of the Brendan Fraser Mummy movies.

Francesca Buller's inspiration for ro-NA's voice came from an old BBC LP that she had of the Beatrix Potter story The Tale of Mrs. Tiggy-Winkle, about a maternal hedgehog.
