My old pal Kevin Ryhal, aka M<O><O>DSWIM, has come up with a truly unique mash-up! He's been creating all sorts of cool combos over the years, from Steampunk Gundams, to Darth Skeletor. But I just looked through his photostream to make sure. This is the first time he's gone for three genres in one. "Jarvis-san, bring the boilers to full power!"
Here's a cute and squee-riffic collection from one of my favorite builders, KOS brick. He calls these Brick Buddies, I call them adorable. They're like Nerdly's pop culture cousins, and I want my own collection of them immediately. Click through for even more of these cuddly little wonders.
Builder tkh / ieyasu has added to this already impressive group of super heroes with the addition of Batman and Green Lantern. I'd say now they're ready to take on just about any challenge. I like how the basic structure is the same on these figs but each is totally unique, and awesome.
