The Tal'darim Executor is a high-ranking military leader within the Tal'darim, a group of "fanatical" protoss.

His forces came into conflict with Raynor's Raiders during the Second Great War.

On Bel'shir, the Raiders intended to acquire terrazine gas from the shrines there. Raynor asked for permission to acquire the terrazine, but the executor was outraged that terrans would try to steal the "Breath of Creation" and sent his forces into combat with the Raiders.

On Xil Raynor's Raiders intended to acquire an alien artifact from a xel'naga temple there. However, the Tal'darim considered this holy, too. The Raiders stole the artifact, prompting the executor to threaten him.
