Harbinger (DC Comics)

An orphan whose ship sunk during a violent storm, Lyla Michaels was rescued from certain doom by the Monitor, a cosmic being locked in an eternal war against his anti-matter counterpart the Anti-Monitor.[1] Raising Lyla as his assistant, the two monitored the multiverse's heroes and arranged for weapons and super-powered henchmen for various villains, to test heroes that the Monitor would recruit for his impending final battle against the Anti-Monitor. The Earth that Lyla was rescued from was Earth Prime (Marv Wolfman said when asked on Facebook about what Earth was she rescued from).

When the Crisis on Infinite Earths began, Lyla assumed the identity of the "Harbinger" after entering a womb-like chamber which energized her and allowed her to create a series of doppelgangers in her new costume. These doppelgangers recruited a wide variety of heroes and villains to fight the Anti-Monitor's shadow demons and protect a series of vibration towers, designed to protect Earth 1 and Earth 2 from the wave of Anti-Matter destroying the DC Multiverse.[2]

However, while recruiting the hero Arion, a shadow demon merged with one of the Harbinger's duplicates, allowing the Anti-Monitor to control her once her various doubles merged into a single entity. Under the Anti-Monitor's control, Lyla killed the Monitor. The Monitor foresaw the Anti-Monitor's gambit and arranged to have his life force be the fuel to power up the vibration towers, saving Earths 1 and 2 from doom. The shock of what she did caused Lyla to revert to a version of her normal form, which then sacrificed all of her powers to save the last three alternate universes (home of the Freedom Fighters, the Charlton heroes, and the Marvel family) from annihilation.

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.[3] 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. 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.[4]

When Kara Zor-El, a.k.a. the original Supergirl, was discovered to exist in the Post-Crisis DC Universe and arrived on Earth, she was given shelter and lodgings on the island of Themyscira.[5] The Harbinger befriended Supergirl and remembering how she sacrificed her life during the original Crisis, the Harbinger willingly died protecting Kara in a failed bid to prevent Darkseid from kidnapping her.[6]
