Star Wars: The Clone Wars introduced Cad Bane to the Star Wars franchise, but the show originally had a different character in mind as its bounty hunter antagonist and it wouldn’t have worked as well. The Star Wars Legends-era character, Durge, would have been fundamentally changed, altering his appearance, motivation, and abilities if he was included in the series, making him a far cry from his original incarnation. The Clone Wars created an original Star Wars character instead, Cad Bane, though another villain with a similar motivation as Durge was created for the series.
The Clone Wars was released at a time when the Star Wars Expanded Universe was still the franchise’s official canon. Despite this, the 2008 show frequently disregarded Expanded Universe lore, rewriting the Clone Wars era of the Star Wars franchise. When the Expanded Universe was rebranded as Legends in 2014, many fans began to handwave The Clone Wars as being exclusively part of the post-2014 canon due to its numerous discrepancies with Legends. The proposed version of Durge, initially a Legends character, would have been completely different from his Legends-era counterpart.

In Legends, Durge was a Gen’Dai, an extremely powerful species with no form and powerful regenerative abilities. Durge also had a violent hatred of Mandalorians, leading him to join the CIS specifically to kill Clone Troopers, who were all Mandalorians in Legends.
