High school teen Duncan Rosenblatt is the son of divorced parents -- a typical suburban soccer mom who wants him to get into a good college and a 300-foot firebreathing dragon called a Kaiju who wants him to follow in the family business: conquering the Earth and inheriting the throne of King of Kaiju; they share custody. Like every other teenager, he struggles to fit in with his peers. His being half-dragon further complicates matters. Duncan is completely resigned to his outcast status and has really stopped caring all that much. His awkward family arrangement forces him and his mother to move a lot.
