I think this came out pretty well for being my first custom. I took a Satellite Armor Iron Man, cracked open his chest and drilled out the chest light. I installed a red LED and a clear piece of plastic to diffuse the light. I also painted the silver on the chest black, and painted the lower jaw black as well, to give him a more menacing look. I added a laser sight to his head, as well as a red visor to his left eye.
Weapons: Gatling gun from Rise of Cobra figure, double barrel blaster on arm from Satellite Armor Iron Man, bazooka on left arm also from Rise of Cobra figure, left shoulder cannons from Zoid Command Wolf.

Thanks for checking this out, and comments are very welcome!
