Hunter Prince

Riiggght. I recommend using a toothpick sanded down to a fine point for the pupil and eyeshine. Do some practice runs on a piece of paper until you're confident.

Isn't Hunter a little shorter than the adults?

He isn't in all that many panels, but he's definitely taller than Wonder Woman. There's one panel where he's looming over her all angry and intimidating. He looks a good 4-6 inches taller than her in that panel. I can't find any panels where he's side by side with Superman; one of them is always angled out in front of the other. But he *looks* like he's pretty close to Clark's height. Definitely looks as heavy as Clark, but then that particular Wonder Man figure is actually bigger than the Superman figure I have...in every dimension except height and chest.

A Marvel Legends Wonder Man would make a great base. It has a similar build, flesh toned arms/shoulders, and the head looks similar, though you could easily mod it.
You can buy it on Walmart.com for about $12 plus shipping.

True. He's a little on the short side, since most of the DC figures are real close to 7 inches, and Wonder Man is only 6.25, but I bet I can find a way to make it work. The eyes shouldn't be too hard to repaint, right?
