Chessmaster Hex is estimated to be 98 years old. His name is an obvious parody of famous MC and rapper, Funkmaster Flex. He was a programmer that had been dubbed a genius from his teens. In the CosmoNet Chess tournaments he held the Champions Seat for decades. He applied his intellect to the Hyperspace Gate Project, joining the program at 30 years of age. He eventually developed the Central Control System that all gates use to this day. But after that he started to have doubts. He said the design had defects and the gates shouldn’t be built yet—he wanted to run more tests. So they fired him and built the gates anyway.
"Hex was furious. He wanted revenge so he used the design defects against the Gate Corporation by giving wanna-be criminals the information they would need to hijack the Astral Gate toll booths. He set up the sting to kick in fifty years later when the gate was pre-scheduled for its first automatic tech upgrade. It was all planned out. He even arranged for his operatives to carry chess pieces to let you know he had finally gotten back at you. But fifty years is a long time; Hex got old, then he got senile. He completely forgot about the traps that he himself had set." - Jet, on Chessmaster Hex.
In the meantime he had been living in a Bohemian Junkheap free from governments, nationalities and the police. He passed the time playing chess, and he claimed that Edward was the first formidable opponent he had in ages. After he won their non-stop chess match that went on for days, he appears to have passed away from old age.
