A member of the Futurist Durlan faction, Halliday and his fellow Durlans hid out on Earth, trying to hide themselves from the main Durlan faction. He became the head of Halliday Worldwide, which was a lynchpin of the Futurist Durlans' operations.
Halliday was being watched by Jack Latham, who suspected him for involvement in a conspiracy with goals antithetical to the welfare of the United States.
When a US senator was assassinated with a Halliday Worldwide weapon, and was subsequently revealed as a Purist Durlan infiltrator, the Mighty Crusaders made a strike against Halliday. Halliday escaped, revealing his shapeshifting powers.
