These legs will become the bottom half of my converted Chaos Space Marine commander that will lead the force I am assembling for the Independent Characters' Hobby Progress Challenge.
I don't think it will take much work to make them "Chaos-y." Maybe take off that diamond spike and use a small bit of green stuff to make a Nurgle symbol.
I was happy to see that the legs fit onto the Necromunda Caller Rat-Beast pretty darn neatly.
Now I need to assemble some more odds and ends.
