The Thrashers were a swoop gang on Nar Shaddaa, under the leadership of the reckless Dug, Unb'tar. They were under the employ of Grubba the Hutt, and were rivals to another of Grubba's gangs, the Slashers. They were wiped out in 15 ABY, by Tatooine Bob's allies during a swoop chase at the Second Battle of Nar Shaddaa. From SW1ki, a Wikia wiki.
