The metallic and glitter variants remind me of back in the 90's when comic shop exclusive figures used to come in dozens of variant colors, lol. The metallic one especially reminds me of a special Lady Death action figure that was vac metalized and had to be ordered from White's Guide to Collecting Figures to get. I keep imagining other variants we could see in the future for Gravestone Guardians inspired by those, like glow in the dark! I would also love to see Black and White variants inspired by old universal monster movies, 'gold' vac metalized variants, completely clear 'crystal' variants....the sky is the limit!
