Sebastian, better known as the Toymaker, is the main antagonist of Spy Kids 3-D: Game Over. He was a former agent of the OSS and former partner of Valentin Avellan. He was imprisoned in cyberspace for betraying the OSS in an incident that cost Valentin the use of his legs, a betrayal that haunted both him and the Toymaker for days to come. The details of the incident were unknown to the modern OSS but the inherent danger of the ex-agent meant he was to be kept in imprisonment for over 30 years.
