Grappa was the designation applied to an exoboar from the brood of Sparky, a sizable exoboar maintained by the Ravagers pirate group located on the planet Rishi circa the time of the Battle of Rishi during the Galactic War. During an incident where [Ruugar](/article/ruugar], the Ravagers' previous leader, contracted outsiders to assault the Ravagers' compound at Coratanni Town with the intent to kill Coratanni, his disloyal second-in-command, Grappa and the rest of Sparky's offspring, who were protecting the town's entrance alongside their parent, were killed by the outsiders.
Grappa is featured as one of more than ten identified exoboars that engage players in combat during the encounter with Sparky within "The Ravagers," an Operation introduced to the video game Star Wars: The Old Republic as part of the 2014 Digital Expansion Star Wars: The Old Republic: Shadow of Revan.
