The head sculpt is quite good, as are most head sculpts done by the Four Horsemen. This isn't a straight up Kirby specific OMAC (the head's too thin and the feature are too rounded) but it certainly captures most of the elements of the character. The hair is spot on, too. He's got the sideburns, the slicked back hair on the sides, and that fantastic Mohawk. That piece of hair is large and in charge. The only baffling thing sculpt wise are OMAC's massively bushy eyebrows. They're ridiculously huge. They may be derived from some other interpretations of the character, but they don't fit this figure that's more Kirbyesque in design.
OMAC's a bright, bold fellow and the paint work matches. Actually, he's molded in many of the necessary colors, but any painted areas are typically neat and clean. The head is perfect- there's even a touch of blue in the hair to mimic the detailing used in older comics. The Brother Eye logo on his chest is a neatly applied tampo and the golden yellow used for his gloves, boots, collar, and belt buckle manage to have a nice shine to them. The only issue I have is that some of the orange plastic from OMAC's legs is showing through on his boots. It's not huge, but it is noticeable.
OMAC doesn't come with any traditional accessories, but he does come with a button and a piece of the series 15 "Collect & Connect" figure Validus. The button has a metal pin on the back and is emblazoned with the Brother Eye logo on the front. I actually like it quite a bit as it does relate to the character. If someone recognizes it on your satchel or backpack, you'll know you've found a true comic nerd. The Validus piece is the right arm. Validus seems like a cool figure, although I don't imagine I'll ever go out of my way to complete him. After the whole Gleek fiasco, I decided to stop being a DCUC completist. Now I just cherry pick the Batman related characters, Jack Kirby characters, and mystical characters. If anyone wants to help me snag a Metron or a Kamandi, you know where to find me.
