The Slams, also known as the Slam gang, were a gang of thugs from Mamendin, in the Galactic Core. They roamed the galaxy, mostly in the Core, pulling scams. They were the gang who notoriously heisted the entire treasury of Vuma.
Roper Slam, a con man, and Valadon, an ID theft expert, were the gang's founders. Other gang members included Waldo, a security expert, and Ukiah, a weapons and defense expert. The Slams kept meticulous records and multiple ID docs for false identities.
The gang was captured and imprisoned in the Greylands Security Complex on Tentator but managed to escape the poorly-maintained high-security prison. However, after attempting—and failing—to break into a Commerce Guild security vault, the gang was recaptured in 24 BBY and sent back to the prison. Their ship, an Ubrikkian star yacht, was later confiscated and used by the Jedi to track down scientist Jenna Zan Arbor.
