Check out the helmet on this Star wars rebel Lego minifig, there’s alot of potential there, and the torso, i reckon will be widely sought after by minifig customizers working on a miltary theme, its by far the closest lego have come to making somethine that resembles a Military theme. next to the Rebel minifig you can see princess Leia with a variant military torso.
Separatist Shuttle custom minifig by no_onions
From the Lego Starwars series, this is one of the alien minifigs, I forgot their names but they are the baddies, the decals are really good, but even better is the Minifigs head gear which could be uses on a custom minifig of a Pope.
Exo-Force Robot with BA Monopod Legs and Arms custom minifig by enigmabadger
Interesting use of the Brickarms monopods to enhance the range of movement and add some hands to this exoforce robot minifig, this gives the custom minifig a better range of movements and improves the stance of the minifig as well, good idea!
A really cool head gear piece by Lego on this minifig, this minifig is part of the Temple of Doom set from Lego. I particularly like the sad face on the headpiece, it adds a little comic touch, the sword also looks interesting.
Chauchilla Cemetery Battle Indiana Jones Lego minifig by no_onions
This one of the new Lego minifigs to be launched in August, the skull face is really cool, but the torso is the real gem, aside from the flesh tone this would be brilliant for custom Zombie minifigs amongst other things.
