Larger than life oil tycoon with daddy issues, Hugh J. Magnate, Jr. He comes to Dimmsdale to build an oil rig hotel, but his attention quickly turns to capturing Timmy’s fairies and using their power to fuel his maniacal ambitions.
Hugh J. Magnate, Junior is a rich oil tycoon who wants to tear down the Dimmsdale Dogwood and turn the park surrounding it into an Oil Well/Hotel. He becomes aware of Timmy's fairy godparents (after Timmy uses their magic to mock him and save Tootie. Then later at a restaurant, Crocker reveals their existence to him), and sets out to capture Cosmo, Wanda and Poof to use for his own nefarious purposes. In his childhood, he never got to do pretty much anything that a child can do in their youth, since his father was so strict about things and deprived him of doing or getting anything that is childish.
At one point in the movie, Hugh J. Magnate, Jr. captures Tootie, who is opposed to his ideas for redeveloping Dimmsdale.
After he lost the power he got from Timmy's fairies, he was sent to an asylum since nobody believed his claims about Timmy's fairies. His assistant, Janice then became the new successor of his company.
