Considering the shear volume of Gears of War custom minifigures that JasBrick has been posting, I'm really interested to see this mystery project he's been touting on the interwebs recently.
Here we have a Gears of War Locust soldier via the way of a custom Buzz Lightyear head. Although Jas has developed a couple of Locust warriors in the past, this seems the most true to form so far.
There are several other custom figs on his Flickr stream, so check them out if you get a chance.
