This is a mug shaped like Emperor Palpatine, a character from the science fiction Star Wars films. This dark lord of the Sith, also known as Darth Sidious, holds his hands in front, ready to blast opponents with some dark side force energy.

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

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.
