Eedund Cus was a male Chevin. Some time after 3 ABY, Cus purchased Lobar Aybock from Zygerrian slavers in order to train him as a shockboxer. Aside from teaching Aybock the art of shockboxing, Cus also taught the Calian to speak Basic and understand Aurebesh.
He referred to himself as 'an unrepentant Separatist' and put no faith in droids.
Behind the scenes
According to author Edward M. Erdelac, the name Eedund Cus came from combining a tuckerization of the surname of Angelo Dundee—Muhammad Ali's boxing cornerman—with the first name of Mike Tyson's trainer, Cus D'Amato.
