Scorpius was born to Rylani Jeema Dellos , a Sebacean woman who was abducted by Scarrans and raped by Wolesh , a soldier-caste Scarran male. She died in childbirth. Scorpius was the only survivor (in 91 attempts) of a breeding program looking into the possibility of hybrid Scarran/Sebaceans and their potential advantages. Under the brutal guidance of a ruling-caste Scarran woman named Tauza , Scorpius spent his childhood forced into rigorous testing to see if such hybrids could be useful. She tried to destroy his Sebacean "weaknesses," such as his susceptibility to heat.When he was 12 cycles old, Scorpius escaped and spent several cycles in the Uncharted Territories unsuccessfully searching for information about his origins. Finally, he turned himself over to the Peacekeepers, offering them inside information about the Scarrans that First Command never had. In exchange for that information, the Peacekeepers told Scorpius the truth about his birth and gave him the location where his mother had been captured . He went there, walking straight into Tauza's trap. Back in her "care," Scorpius soon killed her and helped the Peacekeepers find and destroy the Dreadnought on which he was imprisoned. For his apparent loyalty he received an exemption from all Peacekeeper racial purity regulations and began his career in the Peacekeepers.He quickly advanced in the ranks of the Peacekeeper military and created a special task force to develop wormhole technology. Scorpius' personal goal was revenge against the Scarrans; he sought to harness the potentially limitless power of wormholes and use them as a weapon to help the Peacekeepers annihilate the species that raped and killed his mother.There was one obvious disadvantage to Scorpius' lineage. Scarrans thrive on heat and create mass amounts of it within their bodies, but Sebaceans are especially reactive to high temperatures and suffer from heat delirium with it. Scorpius dealt with this dilemma by using a complicated protective suit and cooling rods inserted into his brain that regulate his body temperature. Gradually the rods heat up, taking the warmth from his body, and must be replaced with fresh, cool ones. The cooling rod apparatus was originally implanted by the Diagnosan Tocot .He also had a very non-trusting but highly sexual relationship with the Scorpion-like alien Natira just a fair percentage of his youth. Prior to Sikozu , she is his only known romantic connection.Scorpius discovered in his youth that his unique heritage gave him the ability to see other beings' "energy signatures. " He found that each species had a particular signature. He can read that energy and be able to identify when they are being untruthful.This ability enabled Scorpius to identify the human John Crichton as a non-Sebacean when they passed in a corridor on Scorpius' secret Gammak Base in the Uncharted Territories.Scorpius interrogated Crichton in the Aurora Chair , a device he had helped the Peacekeepers develop. He discovered that Crichton was also interested in wormholes. In fact, Crichton had information about wormholes implanted in his brain.
Scorpius could not extract that information, and Crichton could not access it, either. Scorpius took a different approach, implanting a neurochip into Crichton's brain designed to gather all the wormhole information and to protect Crichton until the job was done. The neurochip remained in Crichton's head for about a cycle before Scorpius retrieved it.He’s single minded in his pursuit of wormhole technology. He’s extremely evil but in a very cold-blooded way, rarely letting emotion guide his actions. He chased Crichton all over the Uncharted Territories to retrieve a chip he had planted in John’s head. Now that he's in disfavor with the Peacekeepers, he's taken asylum on Moya . Another one of his weird traits - he's made stronger by radioactivity.
