During the events of Star Raiders: The Adventures of Saber Raine (2017) played by Holly Westwood
During a space battle, a pilot notifies the others that a Saurian pilot has broken through their lines. Squadron X, consisting of Talos, Taylor, Nova, Vega, and Dane takes the lead and they attack Crotalus' spaceship. Crotalus avoids them, but her ship is disabled with an ion charge. As Squadron X is about to destroy Crotalus' ship, Saber Raine puts his ship in between the squadron and Crotalus. Taylor tells Saber that his orders are to destroy Crotalus, but Saber insists the orders are wrong. The squadron continues to go after Crotalus and Saber shoots Taylor's ship, disabling its shields. Crotalus is then able to flee.
Years later, on the planet Goros Prime, Saber sees a ship land and makes his way towards the ship and he is watched by Crotalus. As the Annelid Priestess is about to kill Saber, she is shot dead by Crotalus. Fade and Ryll wake up and Crotalus introduces herself. Fade asks Crotalus if she is in a relationship with Saber, and Crotalus tells her they are incompatible. Crotalus takes them to the ruins and Ryll notices that the power to his weapons have been restored. Fade tries to contact Control, but still cannot reach it. A Skelion Guard shoots at Ryll and a battle erupts between Saber and his group and Skelion Guards. Control initiates the recovery protocol once more and contacts Ryll. Caliope, Lorthos and a Quintari walks up to Fade, Ryll and Crotalus and Caliope tells them Tyr is dead. A group of Skelion Guards surround them and Tyr suddenly appears and kills a Skelion Guard and then runs off. Saber appears from hiding and kills the Quintari and a battle erupts. Crotalus kills Lorthos and Tyr and Kor'Rok run up to Saber and his group and tell them their mission is not yet over. Control crashes into the ruins, but Caliope and Sinjin manage to fly away. Saber and the others leave Goros Prime and return to Ares. Saber, who has been promoted by Tyr to lead his military vanguard, and Fade kiss and Crotalus and Ryll walk in and Saber launches his spaceship to hunt Caliope.
