"For some time, our beautiful worlds have been under attack from enemies at all sides: the zerg vermin that want to consume us; the invading protoss who serve their own sinister, alien agenda; and worst of all, the human traitors who have cast their lot with anti-Dominion terrorists. While those threats will be dealt with in time, for now we must focus our efforts on rooting out the true enemy that lurks in the shadows.

Your time to show your complete and total dedication to the Dominion and your Emperor is at hand! Glory awaits!"

Arcturus MengskEmperor of the Dominion
Unit
Race	Terran
Affiliation	Terran Dominion Dominion Armed Forces Royal Guard
Role	Massed infantry divisions supported by elite forces

Arcturus Mengsk is an upcoming commander in Co-op Missions mode. He utilizes masses of recruits to push the front, while "controversial" weapons support his fight against Amon.

The core of Mengsk's army are his Dominion troopers and laborers, conscripted forces who are cheap and easy to produce. They can switch between being a laborer and a trooper as the situation requires, and can equip themselves with powerful weapons, more expensive than they are. These weapons are dropped when they die.

Supporting these are Mengsk's Royal Guard, the most powerful forces of the Terran Dominion that he keeps for his personal safety. These units each have powerful abilities, and as they continue fighting in combat gain veterancy, which gives them more power and allows them to unlock more abilities.

By training troopers and laborers, leveling up the Royal Guard, and by using Imperial Witnesses, Mengsk gains Imperial Edict, which allows him to utilize powerful calldowns.

Development

As one of the iconic villains of StarCraft lore, the goal of Mengsk was to capture his duplicity and ruthlessness. His talk of unity and the "common good" being used to manipulate people was made to be captured in his trooper weapons, which cost more than the troopers themselves and are dropped when the trooper dies, to reflect how little he cares about them. His Royal Guard meanwhile were the elite soldiers he keeps close to his chest, and designed to be used to support troopers with powerful abilities. As the bastion of military power in the Koprulu Sector, Mengsk was made to embody the iconic real-time strategy concept of a commander who entrenches and plays to win at all costs.

The ability to swap laborers for troopers and garrison units within supply bunkers were concepts borrowed from Warcraft III: Reign of Chaos, to allow Mengsk to defend his base with workers alone.
