Fang I was a Captain America villain. Fang III an opponent of Morbius.
Fang II was consumed by a Brood embryo in Uncanny X-Men #162, and ceased to exist as himself. His death as a Brood has not been depicted, but he more than likely died in #167 with the destruction of Broodworld. If an Imperial Guardsman's specific race is not known, they are listed as Shi'ar since they are a part of the Shi'ar Empire. To differentiate between these and true Shi'ar, Lilandra and her people are referred to as Aerie.
