Star Wars underworld figures: Take a look back at Greedo, Jabba the Hutt, and more

With Solo: A Star Wars Story set to explore the iconic smuggler's backstory, might we see some of these familiar faces when it hits theaters on May 25?

Entertainment Weekly’s The Ultimate Guide to Han Solo is on sale now.

While Han worked as a smuggler, other criminals chose lives as bounty hunters, capturing and killing targets for profit. Certain skilled bounty hunters were also recruited by Hutts, like Jabba, to serve as elite bodyguards -- when they weren't being hired to do the Empire's dirty work, that is. Pictured (from left to right) are Darth Vader, Dengar, IG-88, Boba Fett, and Bossk.

Han Solo's most infamous alien encounter was with Greedo -- a Rodian bounty hunter, and far from the only one of his kind. Greedo's fellow Rodians can be found wherever there's scum and villainy afoot. It was from a group of Rodian criminals, for instance, that Sana Starros got the information she needed to find her erstwhile "husband" Han in the comic-book series.

Criminal activity has always flourished on the margins of the galaxy, but it took on a different character under the Empire's rule. Imperial blockades meant there was work for those willing to betray the law, and with the Empire classifying nonhuman aliens as second-class citizens, many did whatever it took to survive. Pictured here (from left), an Abyssin, a Talz, a Bith, and a Sakiyan.

These two species both come from the Outer Rim. From their home world of Nal Hutta, the Hutts run massive criminal empires like Jabba the Hutt's Tattoine operation. Their shady business dealings meant Hutts would work with whatever power served their interests, such as helping the Republic during the Clone Wars (but collaborating with the Empire afterward). Bib Fortuna, a Twi'lek who served as Jabba's criminal consigliere, is from Ryloth, a planet visited several times in the animated show Star Wars Rebels. Rare among Star Wars aliens, Twi'leks look mostly humanoid but for the colorful skin and head tentacles. Their beauty made them prized as slaves.
