The Prematch Clubs consisted of two clubs designed to mimic various cultural implements of the Wookiee people, for example, the Klorri-clan battle shields employed on the planet of Kashyyyk. These clubs were occasionally wielded by the Wookiee Hunters Grozz, previously a Huttballer and Wookiee warrior who fought primarily using melee weaponry. The Prematch Clubs were, in addition, one of two sets of clubs belonging to Grozz that were simulated for standard use in the Boulder Bash hologame, a Hunters of the Outer Rim Holo-Arcade contest located inside Vespaara's Grand Arena.
