Bush is a scientist who originally worked at St. Canard University where he tried to integrate plant chloroplasts into animals in an attempt to give people the ability to feed themselves through photosynthesis. After the funding for his research was cut, he used himself as a test subject in an attempt to prove that his theories were correct and thereby to regain his funding. The experiment was a success but with a price – Bushroot was turned into a half-duck/half-plant creature. He now desperately seeks a friend or girlfriend, and many of his schemes involve attempts to satisfy this need. Bushroot uses his newfound control over plants as his main weapon and views them as people. He was the show's earliest recurring supervillain. He is a likely spoof of the Batman villainess Poison Ivy. He also appears as an antagonist in the Darkwing Duck Dark comic book series.
