I'd joked about sticking a Jurassic Park Ian Malcolm head on a Last Jedi Snoke figure to make an LBC Grandmaster. And that is where I tried to start with this until I a) saw how bad the Malcolm headsculpts were and b) how much the 5 PoA Snoke figures are going for. So I started piecing together a custom that could stand next to the Ragnarok Thor figure and look like they belong with each other. I know the likeness isn't perfect, but there is no good way to capture the Jeff Golblum whimsical magic. Thanks to Kilcarr, there was an attempt to match the crazy hair.
