Mzzrzz was a seer who existed prior to the era of the Galactic Empire. Mzzrzz asserted his awareness of a godly awareness residing within a piece of bantha excrement, which he thought could guide the galaxy toward a new enlightened period. Sometime during his existence, Mzzrzz suffered the loss of at least 50% of his head, yet continued to live for some time even with such wounds. After the Empire captured him and detained him as a captive on the capital ship Executor in 3 ABY, the academic Korin Aphra brought up Mzzrzz and his hypothesis while disputing the Sith Lord Darth Vader's declaration that the Empire fabricated its own past.
Mzzrzz received a mention in the 38th edition of the 2016 Star Wars: Doctor Aphra illustrated story collection. Simon Spurrier penned the issue, and Marvel Comics released it to the public on November 6, 2019.
