When the five remaining universes merged, the Harbinger suddenly regained her power in the process of time and space merging to create a new single DC Universe. Afterwards, the Harbinger recorded the history of the Post-"Crisis" DC Universe into a computer satellite. This led to the Millennium crossover, which had the satellite fall into the hands of the Manhunters, who used the data to confirm the identities of much of the Earth superhero population as part of a greater plan to infiltrate the superhero community. After the miniseries, the Harbinger joined the New Guardians and was infected with the AIDS virus, along with half of the team. She reunited with fellow Monitor allies Pariah and Lady Quark during the War of the Gods crossover, after which she was offered membership with the Amazon tribe of Themyscira as the Amazons' official historian.
