Stalker was a title held by certain members of the Yautja race.
They were the rough equivalent of a Marine sniper with their weapon being the use of the Speargun which had the longest range of any Predator weapon. These were the stealthiest hunters, who maintained a cloaked status for a far longer period than any other Predator. They strongly benefited from enhanced vision mode upgrades with a weapon that significantly outranged its default field of view.
They wore a unique low energy combat suit with microwave optical channeling that enabled cloaked status for far longer periods when compared to a standard Cloak mechanism. However, this came at a price as this suit was far more fragile and provided little armored protection. Furthermore, they restricted the movement of the Yautja, deeming it incapable of moving quickly, making them a target to enemies that detect them.
- A Predator named Stalker is a multiplayer skin in the 2010 video game Aliens vs. Predator, unlocked when players reach Rank 7. However, it bears no relation to the class of the same name from Aliens versus Predator: Extinction.
