Tank was a designation applied to an exoboar from the brood of Sparky, a sizable exoboar owned by the Ravagers pirate group residing on the planet Rishi around the time that the Battle of Rishi occurred during the Galactic War. During the period when [Ruugar](/article/ruugar], the Ravagers' prior head, employed outsiders to assault the Ravagers' compound located in Coratanni Town with the purpose of killing Coratanni, his disloyal second-in-command, the hired individuals exterminated Tank and Sparky's other offspring who were guarding the town's entrance, as well as their parent.
Tank is featured as one of more than ten individually named exoboars that engage players during the encounter with Sparky in the Operation titled "The Ravagers." This Operation was incorporated into the video game Star Wars: The Old Republic as part of the 2014 Digital Expansion Star Wars: The Old Republic: Shadow of Revan.
