History
Valeria's history was presumably similar to her mainstream counterpart up to the point Galactus went mad and started ravenously consuming planets. When Doctor Doom and Reed Richards learned of this, Doom acted too fast and challenged Galactus with his Doom Titan, which would have worked against regular Galactus but not Galactus overflowing with energy from consumed planets. Doom lost and was left drifting in space, barely kept alive by his magic. Meanwhile, the others had acted too slow and Galactus ravaged most of the life in the universe leaving Valeria as one of the only survivors who began to search for Doom.
Two years after Galactus had left Earth barren, Valeria and H.E.R.B.I.E. found Doom and restored him. To fight Galactus, who had been continuously feeding, Valeria infused Doom with Celestial blood, and to help him synthesize it, he was also given one percent Super-Soldier Serum. As for his armor, Valeria provided Doom with a suit composed of Uru, Vibranium, and three Cosmic Cubes.
Valeria informed Doom that Galactus had recently stolen a machine from the Celestials. Doom realized that it was like a bigger version of the Ultimate Nullifier and Galactus was going to use it to reset the universe. With his new body and suit, Doom defeated Galactus' heralds, who were three Molecule Men, while Valeria sabotaged the machine. Unfortunately, she had to sacrifice herself to do it.[1]
