Prouk, a male Korun Akk Guard hailing from Haruun Kal, enjoyed gambling; he had recently lost 60 credits to Nick Rostu right as the Summertime War began.
As the Summertime War drew to a close, Prouk, along with Kar Vastor and his fellow Akk Guards, encountered Mace Windu, a Jedi Master, Nick Rostu, and the troops of the Galactic Republic. During the Battle of Pelek Baw, Prouk used his vibroshields to eliminate numerous clone troopers. Ultimately, Nick Rostu diverted Prouk's attention by shooting at him, which Prouk deflected. Simultaneously, a clone trooper pressed his DC-15A blaster rifle against the Akk Guard and fired, killing him.
