Today I was reflecting on the similarities between Asajj Ventress and Aurra Sing. In addition to both of them being pale near-human women of ill repute, their Legends backstories have some parallels that I found interesting. Both Ventress and Sing were padawans who were taken from poverty and/or enslavement. Both of them left the order in tragic circumstances and both became notorious bounty hunters with reputations for killing Jedi. Other than minor details during the TCW show I've observed on my latest watch-through, those are the biggest parallels I've observed. As part of my search for characters with common conceptual origins, I started looking into whether Aurra and Asajj had spawned from the same concept or something. Both originate out of Episode I concept arts, but I've never found an explicit mention of there being a link. Interestingly, parts of Aurra's backstory regarding her role as a Dark Jedi/bounty hunter originated in the Republic comic a couple years before Asajj's debut in 2003. Is it possible that Aurra served as inspiration for Asajj? Does anyone know anything more concrete?
The two diverge in that Sing was a Fett replication attempt, which didn't work. Never got the same sense from Ventress.
I'm glad that canon did away with the Jedi connection for Sing for just that reason -- too many unnecessary parallels to Ventress, especially given where Ventress's arc ended up going.
