One of two miniseries (with Supreme Power: Nighthawk) typically fit into the Supreme Power reading order between issues #6 and #7. Issue #6 of Doctor Spectrum ends with the events of Issue #5 of Supreme Power.
The alien crystal that powered Hyperion's ship and became embedded in Joe Ledger's arm has plans for him. See those plans unfold here, in the story that couldn't be contained in Supreme Power!
Figures from Ledger's past continue to haunt him, while the government searches for a way to solve the Hyperion problem. As Ledger fights against the crystal for control of his memories and his humanity, the stage is set for an ultimate confrontation! But does Ledger have enough power to control the crystal? Or will it reject him and destroy his humanity in the process?
