The Stalker was a powerful alien who was part of an alien force pursuing the Captive, a parasitic alien villain who escaped imprisonment on a black hole.
The Captive ended up on Earth, landing his space craft on a farm owned by local farmer Jim Hendricks. The pursuing alien force sent three Stalkers to capture the Captive. Jim Hendricks did not realize that the Captive was evil and dangerous. He thought it was a largely helpless refugee, fleeing unjust pursuers. Jim used weapons from the Captive's craft to destroy two Stalkers. Then Captain America arrived (coming to the farm at Jim's request). Captain America ended up in the middle of a battle between the third Stalker and Jim. While the Stalker battled Captain America, Jim shot and killed it with one of the Captive's weapons.
Two other Stalkers were referred to, but only the third and final one was seen in this story. The other two were dipatched by Jim Hendricks prior to Captain America's arrival on the scene.
Given the fact that the hunters of the Captive later used a robot (the Combatron and mineral-based life forms (the Magnoids) to pursue the Captive (who could absorb life force), it is likely that the Stalkers were some sort of artificial life form, or at least an alien type that was "inorganic" in the traditional sense, so that the Captive's life force-absorbing power would not work on it.
