A Judicator, Blackman claims to have travelled from one side of the galaxy to the other, and be knowledgeable of revolutions. By the aftermath of the Brood War, he was leading a mercenary unit, noted for its use of War Reavers. He offered his services to the Terran Dominion to help deal with the New Trinidad Pirates.
The high templar selects a unit, creating two duplicates of it. Hallucinations appear with a blue tint to the creating and controlling player, while all other players will see them as duplicates of the original. Hallucinations do not inflict damage when they "attack", may not cast spells, or produce units (important for hallucinated carriers and reavers), and take double damage from all attacks. Hallucinations last for a limited time and automatically disappear when hit by spells (eg. EMP shockwave, Mind Control).
