Dr. Bushroot was a very intelligent scientist. He was researching a way for animals to be able to do photosynthesis. But the other scientists bullied him, calling him crazy. About to have the funds for his research cut, he becomes desperate and uses his experiment on himself. The experiment turns him into half-animal, half-plant. With his new powers, he get his revenge on the bullies by killing them (notably the only time Bushroot ever attacked someone willingly), and set to use his powers to get money to fund his experiments.
Bushroot later joined the Fearsome Five under the leadership of NegaDuck.
Although Bushroot is very intelligent, he is also a very shy and sad person. All he really wanted was to people to understand his ideals and what he was trying to achieve. He generally don't mean any harm with his plans, yet they tend to backfire horribly on him.
Bushroot appeared in thirteen episodes:
