Tantalus is a character in Darkwing Duck: Darkly Dawns the Duck. He is Taurus Bulba's pet condor. The immense bird of prey played a key role in Bulba's operations, wearing a two-way TV monitor/transmitter on a collar around his neck which allowed Bulba to literally have a bird's eye view of things.
While not anthropomorphic, Tantalus appears to be as intelligent as Bulba's other henchmen, serving in the role of kidnapper, scout, and interrogator (wherein he drops Gosalyn Waddlemeyer from great heights repeatedly at Bulba's order).
He meets his downfall at the hands of the Thunderquack, which rips out his tailfeathers during aerial combat, causing him to fall out of the sky, most likely to his death.
