Shaman and Puck were very easy conversions. After removing them from the 'clix bases and gluing them on the 30mm ones I added an ink wash over their existing paint work. Puck required a little bit of touching up of the black on his uniform but that was it.
Guardian required a lot more work. I applied a very dilute grey wash over the white parts of his uniform, followed by a red wash over the rest. The skin on his face required repainting, as did the black lining around his eyes. Finally I touched up the outline of the red on his uniform and transplanted his flight base to a new 30mm size. I decided that the flight bases are worth keeping, as they both raise the figures up more dynamically, and allows indicating flight/grounded without a token in games of SuperSystem.
Since I already had a converted Sasquatch here's a gratuitous shot of the four members so far.
And as I promised, big scary monster time: Cthulhu.
He'll likely serve as a Winged Nightmare in upcoming games of Strange Aeons.
