Whoah! TOUGH call! TOO MANY!
If pressed to say...
In order
Robocop (3 in my case) for his amazing clean detail. Every time I look at that one, I just sort of swoon. Fantastic finish and amazing it is a toy. Can't wait for Ironman because of this one.
Predator 2 Elder, because the sculpt and finish is awesome. My repaint notwithstanding, I think it represents a point where HT crossed a line between a toy, and a posable statue.
Batman Begins ver 1 with the v2 head. One of the most satisfying figures I have. Fac paint is so dead on, I feel no need to repaint it.
Terminator Endo. Just an amazing piece of toy engineering.
My reworked Hicks. Granted, it has my own head on it, and DA Josh's dirtyin' but he is one hell of a figure. I like all the ALIENS guys a lot.
Predator 2. So cool I almost can't stand it. Too cool!
Wolf Pred. Same thing. With the cleaner kit added to my V1, one of my favorite figures.
Jor-El. I mean...DAMN!
Superman Returns Supes. VERY cool. Needs lifts and a repaint, but it is a super figure.
The Powerloader demands inclusion too. I mean, WOW!
Also rans,
The Joker. Even with my own custom, this one is nice. But yeah, that velcro sux. And the colors still bother me. Sorry guys.
And all the ALIENS. Not all totally movie accurate, but having rubbery slimey dudes that pose and are all...alieny...is way way too cool!
There's more, but these are my faves.
