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 universe (home of the Freedom Fighters, the Charlton heroes, and the Marvel family) from annihilation.
