Lego isn't just about goofy super heroes and cartoony ninjas: so-called AFOLs (Adult Fans of Lego) build and share historical scenes made out of Lego bricks that definitely aren't for kids. In the hands of the right builder, Lego versions of historical events can get pretty brutal.
In their own strange way, these pieces are no different than any Civil War reenactment. The list below features some pretty heavy stuff: war crimes, decapitation, genocide, and historical conflicts with blood-strewn battlefields, events that are gruesome regardless if they're constructed with Legos or 3-D printing. You won't find these Lego MOCs (My Own Creations) at Toys "R" Us, but you may find them in a museum.
