This is a mug shaped like Darth Maul, a character from the science fiction Star Wars films. The evil Sith lord holds his double bladed lightsaber at the ready.

Darth Maul was part of a set of Star Wars Prequel trilogy mugs released at the same time, also including Emperor Palpatine, Queen Amidala, and Jar Jar Binks.

These are a tikified re-imagining of the drinking vessels that might be used if the Mos Eisley Cantina in Star Wars was actually a tiki bar.
