Little is known about Melissa's life before being recruited by Nighthawk to serve in his team of super powered "Redeemers" to fight the influence of the Squadron Supreme's "Utopia Program" on their alternate earth. Moonglow, along with other Redeemers Inertia, Thermite, Haywire and Redstone, infiltrated the Squadron and was elected to full membership. She served for a month before the Redeemers openly opposed the Squadron. During the final battle, Melissa was knocked unconscious and her true figure was revealed to be an overweight, frumpy woman. Embarassed by her true form, Melissa remained invisible while the Squadron began dismantling the Utopia Program.

When the team left to confront the Nth Man, whose existence threatend the Squadron's Earth, Melissa agreed to let Arcanna go in her place, as Arcanna's own powers of illusion would mask herself.

The final fate of Melissa Hanover remains unrevealed.
