Doctor Spectrum was a construct created by the demon Mephisto and programmed by the Power Elite in cooperation with a recently-revived Agent Coulson to be a member of the Squadron Supreme of America, a superhero team sponsored by the U.S. Government. Doctor Spectrum's programming had him believe that he was an astronaut named Joseph Ledger that discovered a Power Prism on a space walk, which granted him superhuman powers.
Doctor Spectrum and his team were brought in to meet General Ross in order to be the U.S.'s response to the now-unaligned Avengers. The Squadron Supreme was later put to the test against King Namor and his Defenders of the Deep, countering several attacks against Roxxon in American waters.
Joseph was on his office when a group of Frost Giants from Jotunheim invaded Washington on behalf of Malekith the Accursed during his War of the Realms. As Doctor Spectrum, Ledger met up with the rest of the Squadron. They killed some of the Frost Giants and routed the remaining invaders to the Canadian frontier in Lake Erie. Coulson subsequently dispatched the team to Ohio.
Coulson attempted to warp reality using the Pandemonium Cube provided by Mephisto, creating Earth-TRN852, where the Avengers never existed and the Squadron Supreme were the world's premiere superhero team. Reality was eventually restored by Blade the Vampire Hunter and his team of Avengers. So, Mephisto punished Coulson by trapping him in the Pandemonium Cube. Without Coulson, the Squadron Supreme fell apart, and Spectrum was taken into government custody. When reality returned to normal, Spectrum possessed his Earth-TRN852 counterpart's memories. Also like his Earth-TRN852 counterpart, his Power Prism was destroyed. This left Spectrum emotionally devastated and didn't seem to be cooperative when questioned by government officials.
