Bounty hunters are shape-shifting aliens who have the ability to disguise themselves as anyone, although they commonly assume a specific appearance that they can maintain at the same time as each other. (TXF: "Colony", "Within") Regardless of how they are disguised, bounty hunters are immediately recognizable to clones. (TXF: "Colony") Due to the toxic nature of their blood (which, like that of the clones, is green), human exposure to it is fatal. Bounty hunters can only be killed by precisely piercing the base of their skulls. (TXF: "End Game") They all seem to use the same human form as their default form. Some of the faceless alien rebels use this form as well. They may be of the same extraterrestrial race as the faceless rebel aliens and/or the Grey aliens. (TXF: "The Unnatural")
