Here is the Master Chief, Sergeant Johnson, and Miranda Keyes, the main human characters in Halo. I have proven that it is possible to make pretty close minifigs without the use of decals. The one thing suspicious about this model is the Masterchief's golden visor, it is actually a little piece of golden wrapping paper squeezed between the helmet and the head, but i plan to get a real golden visor from a mars set soon, sorry if that offends some extreme LEGO purists. It is true that none of these minifigs use decals. The Chief's body is that of a kashyyyk trooper with some matching legs i found. The Sergeant is made using Tony Parkers minifig head (lego basketball), a stuntman body, and samurai armor. Miranda Keyes has the body of an imperial officer with Princess Leia's face. Sorry I didn't include my marine in the photo. I wanted to include my arbiter, but Im not sure if I can post it because it is Justin's (saber scorpion) design.
