A battle-hardened Sontaran General. Unlike his kin, Serk is not just a warrior but a strategist, willing to bend Sontaran tradition if it means victory. Brutal and uncompromising, he sees the Doctor as both a threat and a prize. Serk’s motivation is tied to desperation—his race’s breeding planet is gone, forcing him to abduct humans for twisted experiments. He embodies both the pride and the tragedy of the Sontaran race.

Commander Saltera

Serk’s second-in-command. Less flamboyant but no less dangerous, Saltera is loyal to Sontaran ideals and questions Serk’s strategies only when they threaten efficiency. Cold, disciplined, and merciless, he represents the unshakable military machine the Sontarans are known for.
