Opun "Black Hole" Mcgrrrr, son of Hethra Mcgrrrr, who established the Black Hole Pirates, once held ownership of the Holiday Towers hotel located on Cloud City. However, control was later seized by Jabba Desilijic Tiure.
In the year 0 BBY, Mcgrrrr sought retribution for Jabba's takeover of the Holiday Towers. As a guest in Jabba's town house situated in Mos Eisley, he absconded with the droid known as CZ-3. His objective was to retaliate against Jabba by uncovering the droid's hidden secrets. Unbeknownst to Mcgrrrr, Jabba had anticipated this move, and CZ-3 was actually spying on him. The entire endeavor turned out to be an elaborate trap orchestrated by Jabba.
This scheme was disrupted when Aguilae, a Jawa, and her companion, Macemillian-winduarté, a Squib, pilfered the droid from him (or, as they maintained, discovered or procured it after it malfunctioned and went rogue). Enraged, Mcgrrrr dispatched his Jenet underling, Tols Vengra, to retrieve the droid.
Vengra located the droid concurrently with Takeel, Jabba's bounty hunter. As they quarreled, Takeel's sibling, Zutton, discharged his weapon, obliterating the droid. Nevertheless, in doing so, CZ-3 had furnished Jabba with sufficient evidence to expose Mcgrrrr and Vengra's machinations against him.
Mcgrrrr's visual design drew inspiration from Declan Mulholland, the actor who portrayed a Human version of Jabba the Hutt in a scene featured in A New Hope. Mulholland sported a comparable ensemble in the film Time Bandits.
