I found a Metro City soldier figure from Astroboy on a clearance rack at toysrus and found it made a perfect base for a SWAT bot. I used the colors from the cartoon instead of the comic because I always liked them better. A real pain was having to make the head twice, because the first plastic dome I molded the head around lost its shape in the hot water used to cure the clay and part of the face fell off. My second head didn't come out as well as that first one T_T
