Taurus Bulba, later known as Steerminator, is a Secondary Antagonist in Darkwing Duck. He is a big, fearsome bull who wants power at any cost. He was the very first villain Darkwing Duck ever fought onscreen, though canonically he is the second villain that Darkwing ever faced, only behind Megavolt. He has an incredible hatred towards Darkwing (due to the duck's ego), though ironically, his defeat turned Darkwing into a hero.
He was voiced by the legendary British actor, Tim Curry, who also played several villains such as Hexxus, Maestro Forte, and El Malefico among others.In the non-canon continuation of the Darkwing Duck story via an 18 issue comic series, the story jumps forward many months later and St. Canard seemingly no longer needs Darkwing Duck due to mechanical police units created by a mysterious company called Quackworks. Later, upon Darkwing's return to crime fighting, Taurus Bulba is revealed to have rebuilt himself and has founded Quackworks as a means to rid the city of heroes and villains as well as to become the hidden ruler of St. Canard. He also seeks the Gizmoduck suit as a means of increasing his power, however, with help from his allies, Darkwing destroys Taurus' newest body and while trying to escape, fights him again as he has returned in another body. Fortunately, Gosalyn, using the Gizmoduck suit, permanently deactivates Bulba's final body, resulting in his final demise.
