Mysterious Mercenary Pursuer

This is a character with the following traits:

• A mercenary, bounty hunter or assassin.
• Antagonist sent to capture/kill protagonist(s)
• Relentless in pursuit of protagonists. Usually a Determinator, often an Implacable Man. Sometimes the protagonists will try to pay him off, but he'll always ignore the offer and get killed off.
• Mysterious in one or more gimmicky ways. Sometimes he's The Faceless, sometimes The Voiceless, sometimes he isn't named except in an Everyone Calls Him "Barkeep" way, sometimes he wears a concealing suit of armor, sometimes he has an unexplained facial scar, sometimes he turns out be a she...

The difficulties involved in getting such incredible commitment from Hired Guns may or may not be addressed. Often a Hero-Killer.

Examples of Mysterious Mercenary Pursuer include:

• Toyota the ninja from Y: The Last Man, with the twist that she eventually gets more characterization and rather than a stoic, silent ninja, turns out to be a huge bitch and Arrogant Ninjitsu Chick.
• The Man in Black from the Farscape comics, who is The Faceless and The Voiceless for the first few story arcs. He's trying to kill Deke, Crichton and Aeryn's newborn son.

• Boba Fett from Star Wars. He talks very little and wears a concealing suit of armor. Was mysterious in the original films, but dozens of novels and the prequel trilogy killed much of his mystique.

• The Coen brothers seem to like stories with guys like this. My first thought was Anton from No Country for Old Men.
• Joe Lefors in Butch Cassidy and the Sundance Kid. So mysterious, he's never even properly seen in the film. Butch and Sundance see him once from a distance of a mile or more, then later on see someone they assume is him from behind, although it's not clear if it's really Lefors or just paranoia on their part.
  • You can also tell it's Joe Lefors because he always wears a white straw hat.
• The assassin sent to get Carter in Get Carter. He has no dialogue and is distinguished only by his signet ring, inscribed with a J.
• Dragan, the assassin hired by Serbian mobsters in Layer Cake. Seen only briefly at the end, he tracks the protagonist through almost the entire film and is always a step ahead.

• The Man in Black was this to the three bandits who kidnapped Buttercup in The Princess Bride.

  • Considering the result of the war he might well have been relieved to get home.
