Transformed Body: Dagny Forrester has existed in three different states since beginning the Corona experiments. The above statistics (Alternate Form) apply to Dagny in her human form as well as her incomplete and complete Corona forms. The statistics for the hideous breakdown form in which Dagny is presently trapped are detailed at the top. In her initial or incomplete Corona form, Dagny had the following powers:
Energy Corona: Corona’s cells produce vast quantities of energy which fuel an aura surrounding her. This aura can transmute Incredible material or less in to a gaseous state, thus granting her Incredible Body Armor against such attacks. All energy, blunt, grappling, and charging attacks affect Corona normally, but the attacker may suffer up to Incredible damage from her aura.
Flight: Corona’s powers allow her to fly at Typical air speeds (6 areas per round or 90 mph).
Energy Blasts: Corona can fire blasts of energy up to four areas away, or use them to alter the chemical state of the object she hits. For example a solid can be reduced to its molten or liquid form. Such a transformation is accompanied by the object “heating up” to melting point (1,535 degrees Celsius for iron). Corona can fire force blasts by altering the various gases in the area which sur round her. These blasts can be up to Incredible Intensity.

In addition to all of the above powers, in her complete Corona form Dagny add ed the following power:
Transmutation Power: Corona can reach into the molecular structure of an object and alter its physical state, turning it from or to solid, liquid, or gas. She can also make changes to the molecular structure of matter. Both these abilities function at an Amazing level and 4 area range.

In this form, Dagny’s thick hide provides her with Good body armor. She also has the Lightning Speed power at Good rank (4 areas per turn).

When she did return, she interrupted an interview Cedric was engaged in with Daily Bugle reporter Joy Mercado, who was accompanied by photographer Peter Parker. Mercado and Parker witnessed Cedric’s hired goons, armed with assault weapons, making their way to the top of the Forrester Building. During the commotion, Peter changed into his Spider-Man suit and arrived in time to stop one of the security guards, who had negated Corona’s powers with an energy-retardant foam, from physically abusing her. Spider-Man’s intervention was enough to allow Corona to obtain what she had come back for—Cedric’s laptop computer. When Spider-Man eventually caught up with Corona, she lied to him, saying that she had been an unwilling participant in the experiments.

In a second encounter with Corona, Spider-Man learned that the Corona experiments were responsible for the Soho Fever, which had stricken his wife among many others. Corona told Spider-Man that Cedric had developed an antidote for Soho Fever, but would not come forward with it for fear of being blamed for the initial outbreak. Spider-Man, with Corona in tow, stormed the Forrester building intent on getting the antidote. As it turned out, Corona wanted the antidote to complete her transformation. She claimed it would give her the power to cure those ill with Soho Fever with a wave of her hand. As the ingredients in the antidote were quite rare, there was no chance of making a second batch. Not sure if he could trust her, Spider-Man stayed between Corona and the antidote’s glass storage tank. Desperate for the chemicals, she fired at Spider-Man, but missed and struck the storage tank. Moments after the last of the antidote trickled down a nearby floor drain, Corona became aglow in a blaze of energy. Without the chemicals in the antidote, Corona had undergone the biological breakdown she had feared and now had the appearance of a hideous monster. Though she desperately wanted to take revenge on Spider-Man for his role in turning her into a monster, she wanted to hear him confess to what she surmised to be the truth, that Spider- Man had been in league with her brother all along. Only her fear of being captured caused her to abandon her captive.

After regaining consciousness, Spidey hatched a plan for producing anti dote by teaming Harry Osborn with Cedric. Spidey’s theory was that Harry would be able to come up with the chemicals Cedric needed. Meanwhile, Corona had broken into the one of the labs on the campus of E.S.U. and was using a field acceleration chamber to complete her transformation. She blasted through the roof of the Forrester Building intent on killing her betrayers—Cedric and Spider-Man. Spider-Man led Corona away so Harry and Cedric could finish the antidote. After a protracted discussion, Spider-Man convinced Corona to use her powers to help produce the anti dote. When Corona walked into the Forrester Building, however, she was struck from behind by a power siphoning disk, which caused her to revert to her freakish form. Not willing to be captured, Corona broke through a wall. She then threw herself from the top of a building in an attempt to take her own life. Spider- Man was able to rescue her. In one last burst of strength, Spidey dispatched eleven of Cedric’s hired goons and man aged to make a phone call before succumbing to the fever.

Spidey was revived by a shot of anti dote administered by Harry Osborn. The phone call he had made had been to the Reed Richards of the Fantastic Four who showed up and promised to try to reverse the effects of Corona’s mutations, though he admitted he hadn’t had the best of luck in this area in the past. Unfortunately, for these best laid plans and Dagny, Cedric showed up with a court order which remanded her to his custody as her only living relative. The news was that all charges against him had been dropped because of his quick and decisive action in formulating an antidote. Corona was last seen pleading for help while being taken away in a containment tank by Cedric and his men.
