Sovereign is the mastermind behind the increased criminal activity in City 31, as well as the leader of the Shrike. His devotion towards plunging City 31 into the chaos and his hatred for the XCOM makes to wonder about his true intentions. As the unit, Sovereign is the superior variant of the Shrike Hitman.
- Disabling Shot: Sovereign makes the shot at the target, and if hit, disables the latter's weapon. Automatically enters Sovereign into small radius Overwatch.
- Sustain: If Sovereign takes enough damage to be killed, he is immediately put in Stasis for 1 turn and his health is only reduced to 1 HP. This can only happen once per mission.
