Gift from JeffK from Star Wars convention
This mug is based on the main character from the Disney+ Star Wars series, The Mandalorian.
The Mandalorian is basically a science fiction version of a Paladin/knight in shining armor. He lives by a set of rigid codes, one of which is never to remove his helmet. In the series, he becomes the protector of Grogu (often referred to as The Child or Baby Yoda) whose literal blood is sought after by the evil scientists of the old Empire who wish to make force-sensitive clones for their dastardly plans. The Mandalorian dresses in special armor made from Beskar steel which is from his home planet and is resistant even to direct laser blasts or hits from a lightsaber.
