One of the two Xindi-Aquatic representatives on the Xindi Council, a cautious deliberator whose species eventually sides with Degra and Jonathan Archer against the Reptilians and Insectoids.
Kiaphet Amman'sor is a Xindi-Aquatic councillor seen during the third season of Enterprise, notably in The Council, Countdown and Zero Hour. The Aquatics attend the Council in a water-filled chamber and speak in a sonar-like language.
The Aquatics are slow and deliberate by nature, demanding proof before acting. When Archer presents evidence that the sphere-builders have manipulated the Xindi into attacking Earth, Kiaphet's faction is persuaded to delay the weapon's launch.
After the Reptilians and Insectoids seize the weapon, the Aquatics commit their powerful ships to the pursuit, carrying Enterprise inside one of their cruisers to reach Earth in time.
