Crossbones is one of the Red Skull's most loyal followers. Sin is the daughter of the Red Skull, Sinthea Schmidt. Both came to prominence during Ed Brubaker's Captain America run, but both originally appeared in the 1980's. I want to do the more human-looking version of Sin as well...someday.

Crossbones is simply the head and vest from the single-carded Captain America: The First Avenger Crossbones and the body of Ninja Dojo Roadblock. I added a fodder belt that has a knife and holster, a fodder pistol, and a fodder gun which I think is from the World Peacekeepers line. I painted some details on the gun and freshened the brass bullets on the vest. I also removed the camo from Roadblock's arms. This version stands taller than the MU or MI Captain America - Hasbro's version is just too short.

Sin is the Red Skull head from the Captain America movies with a dark wash, and the body from the ROC Scarlett with reactive armor. The machine pistol is from a Baroness.

These are easy customs for a beginner, and make a nice addition to your Hydra display.
