A company named "Lego" has a Master Chief Halo figure listed on Amazon at the moment (March 2011) http://www.amazon.com/HALO-Master-Chief-Navy-Blue/dp/B001L18CK2 This may not be an official Lego product. However, it will interchange with Lego pieces. It is a complete figure. If you wish to make your own, BrickForge makes custom armor, BrickArms the guns. This is most likely where the parts for the "Lego" product above come from. It would be cheaper to buy the pieces and make your own, especially if you want more than one. Kubricks also has parts that interchange with Lego, including a Master Chief from Halo figure.
