Topa is the son of Bortus and Klyden, born of the egg that Bortus had laid. While originally female, Topa underwent sex reassignment surgery shortly after birth. His parents, Bortus and Klyden, were originally in agreement in the decision to subject their child to sex reassignment surgery (SRS) to correct the "birth defect" of being born as a female. After asking Dr. Claire Finn to perform the SRS and being denied, Bortus made an appeal to Captain Ed Mercer to order Claire to perform the surgery who also denied the request. The surgery was eventually performed by Moclan doctors.
