A feared bounty hunter known for her chalk-white skin and built-in comlink antenna, Aurra Sing was an expert sniper and trained assassin who will work for anyone who pays her.
After the death of Jango Fett, Aurra trained Boba Fett as a bounty hunter, teaching him the skills -- and the ruthlessness -- that he would need in pursuing his deadly profession.
Aurra Sing served as a mentor to Boba Fett when the young boy was left alone following the death of his father, Jango, by a Jedi Knight. Aurra plotted to help Boba exact vengeance against Mace Windu.
Aurra Sing was a former lover of Hondo's and sought his help on Florrum while on the run from Mace Windu, who wanted to detain her and her bounty hunter accomplices. Ohnaka refused her request, but claimed he would not hinder her attempt at escape -- or attack -- either.
Although incarcerated, Ziro the Hutt had enough pull in the criminal underworld to hire Aurra Sing to assassinate Padmé Amidala.
Ahsoka Tano pursued Aurra Sing on Florrum, and stopped the bounty hunter from fleeing the planet by crippling her escape craft. Aurra Sing was believed killed in the crash, but Ahsoka kept having visions of the bounty hunter through the Force -- visions that warned her of Aurra attempting to assassinate Padmé Amidala.
When Aurra Sing served as a guardian to young Boba Fett, she took to piloting the Slave I. She flew the craft to Florrum, where it was extensively damaged in a frantic attempt to escape a Jedi pursuit. Ahsoka Tano sheered off one of the Slave I's stabilizers, causing the ship to crash into the desert.
