Oily Bird

Oily Bird is a duck who was somehow mutated by an oil spill. He functions as a recurring enemy of the Conservation Corps.

Oily Bird is defeated in Espirit de Corps when Benevolence's ship explodes. Cudley the Cowlick takes Benevolence and Oily Bird to Benevolence's dying home planet of Danopaulus so that Oily Bird would cause no more harm when he came to.

However, at the end of A Fish Out of Water, Oily Bird returns with cybernetic enhancements as Robo Oily Bird, working for Benevolence's evil brother Malevolence.
