Benno was a leader in the Black Vulkars swoop gang on the planet Taris' Lower City during the Mandalorian Wars. In approximately 3964 BBY, Benno commanded a crew of several gang members, including the Drovian Wargo and the Zabrak Frazznik, and was well-known as an impatient and gruff individual not given to deep thought.
Benno was a member of the Black Vulkars swoop gang in the planet Taris' Lower City in the era of the Mandalorian Wars. By around 3964 BBY, Benno had become a leader within the Vulkars, commanding a crew that included the Drovian Wargo and the Zabrak Frazznik. Around that year, Benno's crew captured two wanted fugitives—Jedi Padawan Zayne Carrick, accused of murdering four of his classmates in Taris' Jedi Tower, and an accomplice, local Snivvian hood Marn Hierogryph. However, Hierogryph, who was familiar with Benno's impatience and his dislike for Upper City ways, convinced Wargo and Frazznik to let them go rather than turn them over to Benno so he could claim the bounty on their heads.
A gruff and unintellectual individual, Benno was regarded by his crew as one who did not like to think. Benno was impatient and disliked Upper City bureaucracy and delays, along with having to wear Upper City clothes. Benno inspired a measure of respect and fear within the members of his crew, who would go to great lengths so as not to displease him.
Benno was mentioned in Knights of the Old Republic 3, a comic written by John Jackson Miller and released on March 29, 2006.
