Professor Zlana van Hydroolik is a female anthropomorphic duck.
Description[]
Zlana van Hydroolik is a mad geneticist with an inexplicable, stalkerish crush on Gyro Gearloose, whom she holds to be her only kindred spirit. She was hired by Scrooge McDuck to create Square Eggs after the failure of Scrooge's Plain Awful scheme, but became obsessed with turning everything square, forcing him to let her go.
She resurfaced in 2020, kidnapping Huey, Dewey and Louie Duck and using her Quack-o-Matic to use their genetic template to create artificially-grown rectangular clones of the ducklings, all for mysterious backers such as the malevolent Baron Von Spann. Using a Spy Bug, she was able to watch Scrooge's reaction to her letter announcing this breakthrough.
