I used the body of a foot soldier from the movie star turtles line
Shaved off the strap that went across his chest
I used the spikes from the original ninja turtles shredder and painted them
the head and masks are from the TNMT line shredder
I had to open up the eye section to make it look like the movie version
The figure is a full repaint
The additional helmet from ninja turtles 2 was done the same way but dremeled to add the spikes and texture
