STARCRAFT PROTOSS STALKER

The fall of Aiur showed the Nerazim that more than stealth was required to defeat the zerg, and thus they developed the Stalker - a war machine controlled by the shadow-esence of a Dark Templar warrior fused into a metal body. This ranged strider also posseses the ability to displace itself and reappear elsewhere, making them ideal at ambushing or generally engaging only on their terms.
