The USS Indomitable is part of the fleet of the United Solar System Alliance and home to the parents of Sparks Nevada. While their primary goal remains unknown, their known missions have so far been concerned with the murderous murdermen (homocido sapiens). In their first appearance they rescued the Pride of Uranus with the help of Sparks Nevada.
