I would definitely have to say Ghost Predator, or City Hunter to you folks here.. I actually liked him because he was a Predator who had displayed a sense of martial skill. Rather than taking the stealth approach which Diablo or Jungle Hunter did, he was more of a close quarters kind of Hunter and really seemed to enjoy that approach. He fought the way which I felt Predators could fight, especially with the staff when he was slaughtering Keyes' men in the meat house.
For a younger and inexperienced Hunter, he was quite talented and showed a lot of potential. He had skill, he had talent and he didn't fight like a damn ape like the Super Predators did in PREDATORS.
