The construction of the Lego Eva Units

Leftmost is the basic black body of the evas (pictured with the alternative 'bandaged' head).
The 3 sets of coloured pieces to the right were interchanged to form the different Evas.
This was due to Lego poverty, (didn't have the right bits to make all 3 at once,) but is also kind of a pleasing modular way of doing things!
