Citadel Robotnik

Citadel Robotnik was the main headquarters of Doctor Ivo Robotnik during the latter half of his dictatorship of Mobius. Based in the Metropolis Zone, it served as his capital building, and allowed him to keep a much closer eye on his people that had been possible from his earlier bases in the Special Zone and Launch Base Zone.

The Citadel was built after the destruction of the second Death Egg and the abandonment of Robotnik's old Egg Fortress. .

Robotnik maintains an office in the Citadel, with Receptionik acting as his secretary and personal assistant.
