During Hadiss's reign, a Geonosian named Poggle the Lesser was born into the lower castes of the hive and set his sights on becoming archduke. Gathering followers among the lower castes, Poggle attacked Hadiss's more valued installations and individuals, with the conflict between the two escalating until Poggle himself killed Hadiss shortly before the First Battle of Geonosis occurred in 22 BBY.
In the current Star Wars canon, Hadiss was first mentioned in "Visiting Geonosis," an article published in the "Guide to the Galaxy" department of Star Wars: Build the Millennium Falcon 19, a magazine published by De Agostini around May 13, 2015.
