Snively Robotnik (born Colin Kintobor Jr.) was the Overlander nephew of the infamous world-despot Dr. Ivo Robotnik (formerly Julian Kintobor). Snively was both devious and treacherous, and was responsible for his uncle's death when he reprogrammed the Ultimate Annihilator to target only his DNA. Following this, Snively attempted to secure control over his late-uncle's empire, only to be captured and imprisoned by the Freedom Fighters. After escaping from prison and being the temporary leader of the other escapees, Snively eventually joined the alternate-universe counterpart of his deceased uncle, Dr. Eggman, though their relationship has been even more antagonistic than that between Snively and the original Robotnik. Snively eventually entered into a secret relationship with Regina Ferrum,
