At some point prior to the Belkan War, Porter joined the Osean Air Defense Force and was assigned to the Wizard Team. Following the Belkan War's official conclusion, Porter and the squadron defected to A World With No Boundaries. On December 31, 1995, they engaged the Galm Team over Area B7R, where Porter was shot down.
Porter was later accused of being involved in the assassination attempt on the President of Osea in 1996. He was charged since he made more than 20 trips to Yuktobania six months prior to the incident, with others testifying against him. He denied all accusations and was later imprisoned.
