This is sort of an easy one: My Cthulhu Pop! I have been a longtime Lovecraft fan, and the first thing that comes to mind when anyone mentions him is this iconic cosmic diety! The Pop itself is greatly detailed, which is part of why I love it so much. Aww, look, his eyes are even half-lidded because he's The Sleeper of R'lyeh! Or that could be his disdain for all of humanity.
Oh, and I said sort of, because of course there are variations! I also have the glow in the dark variant, and am looking forward to getting my patina Cthulhu soon! I would be hard-pressed to pick among the three, but of course the original is my favorite. Ia! Ia! Cthulhu Fhtagn!
