The Planet / War Hulk is by far my favorite Hulk base out there. I wanted to make the figure so he could either be Planet Hulk, War Hulk or Mark Ruffalo Hulk. I basically just inserted a 1/2" Chrome ball into the neck socket (which required a lot of sanding on the shoulders) and gave the skin a full repaint which is the same as my other Hulk custom. I also used the HML Savage Hulk Head in place of the Planed Hulk head.
Sorry for the crappy pics, I'm doing this through my phone as my computer is on the fritz.
Thanks for looking!
