Metalbeard is a character from The Lego Movie who wanted revenge on Lord Business for taking his old body. He is voiced by Nick Offerman.
Metalbeard was originally a typical pirate character who was a member of the Master Builders that opposed Lord Business. He originally led a team of Builders (including the Flash) on a mission to invade and conquer Lord Business' tower, but they were all kidnapped and were imprisoned to the Think Tank and Metal Beard escaped with only his head. Metalbeard then rebuilt himself to be a more powerful foe. His pirate-robot hybrid form is a testament to the free-thinking of the Master Builders.
