Aurra Sing is a bounty hunter who first appeared in a blink-and-you’ll-miss-it cameo in The Phantom Menace. She played a much larger role in several episodes of Star Wars: The Clone Wars where her connection to a young Boba Fett is revealed.
Aurra Sing also appeared in the last four of the five-issue comic series Darth Maul and the mobile games Star Wars: Galactic Defense and Star Wars: Force Arena.
Those truly impressed with Aurra (and bounty hunters in general) may want to check out the book Aurra Sing: Dawn of the Bounty Hunters, which comes with a pretty cool looking figure of Aurra Sing.
You can learn much more about Aurra on her Wookiepedia page.
