A Vaadwaur military leader revived in 2376 after nine centuries in stasis, who accepts Voyager's help in leaving his ruined homeworld while secretly planning to seize the ship.
Gaul appears in the sixth-season Voyager episode Dragon's Teeth, played by Robert Knepper. He is a senior officer among the Vaadwaur battalion that went into underground stasis when their world was bombarded by enemies, intending to sleep for five years and instead lying dormant for some nine hundred.
Once Seven of Nine revives the first survivor, Gedrin, Gaul and the others are awakened and present themselves to Captain Janeway as the innocent victims of the Turei. Gaul negotiates for Voyager's help in escaping the planet through the subspace corridors his people once controlled.
In private he argues that the Vaadwaur need a powerful ship to rebuild and plots to take Voyager by force. When Janeway learns of their history of conquest, his fighters attack, and Gedrin turns against him to help Voyager escape.
