Titan was a member of the Imperial Guard, a multi-special group of super-powered alien beings who acted as enforcers of the laws of the Shi'ar Empire. Titan was amongst the first of the Imperial Guard encountered by the team of superhuman mutant adventurers known as the X-Men who sought to rescue the Princess-Majestrix Lilandra from her insane brother, then-Majesty D'Ken. Following the orders of their emperor, the Guard clashed with the X-Men and were on the verge of winning when the band of interstellar freebooters known as the Starjammers arrived to turn the tide of battle in the X-Men's favor.
During Vulcan's rampage through the Shi'ar Empire, the Imperial Guard are forced to engage him on one of the Shi'ar moons. Later, during Thanos' invasion on Earth, Titan was killed when the Imperial Guard helped the Avengers free their planet.
