The McFarlane DC Multiverse Mr Freeze figure is one of my favourites from that line. I think the sculpt is terrific and captures so many little details, and it works great as a default design for Mr Freeze. Unfortunately, the paint apps are pretty basic, which is why this figure has become a very popular one to mod and repaint.

Besides repainting the figure, I swapped out the head for a cast of a Westworld Man in Black head. I had always envisioned Ed Harris as a live-action Mr Freeze, but unfortunately, I think I lost all the likeness by the time I was done. I made removeable goggles using the goggles from a Star Wars Black Series Hera Syndulla figure. I also drilled holds in the backpack gas canisters and the freeze gun to connect a hose (Superior Doc Ock tentacle) between them. I heated the freeze ray to make it removeable too. Thanks for looking!
