Engineered during the Neural Compliance Initiative as living command processors, Circuit Sovereigns evolved from tactical AIs into hybrid human-cybernetic entities after being implanted with Commander Thorne's neural patterns during the Black Mesa Uprising.

Subdermal command interfaces synchronize with Steel Eagle's tactical network, adaptive authority matrices expand control radius during crises, cryptographic loyalty enforcers in spinal cybernetics suppress dissent, self-replicating protocol nodes maintain operational continuity.

Simultaneously coordinate missions and enforce neural compliance across Echo Sentinel strike teams through real-time tactical verdicts and cybernetic override protocols.
