Titan is a member of the Imperial Guard which is a legion of super-powered champions who protect and defend the Shi'ar galactic empire. Its members are drawn both from the Shi'ar and other alien races governed by the Shi'ar. The majority of the Imperial Guard's members are known as Borderers. They assist the governors of conquered planets in enforcing the Shi'ar imperial law. The Imperial Guardsmen however belong to the elite corps that protects the ruler of the empire, known as the Majestor or Majestrix, and executes his or her orders. Nothing much is known about Titan's history or if his humanlike appearance means he comes from earth.
Titan was created by Chris Claremont and Dave Cockrum in 1977 and first appeared in X-Men # 107 (1977). He was based on the DC Comics superhero from the 30th century Colossal Boy, as were many of the other Imperial Guards fashioned after members of the Legion of Super-heroes.
