So - if I am reading that right - Sas is the "build a figure" - meaning you need to get the others and build him?

Which is a bit of a pain. Hate when they do those "Build A Figures" - because the idea of buying two (one to nail to a wall and hang up - uh, still in the case, not nail the figure!) - and one to open and put on your desk - because a costly, collecting, nightmare.
