Unknown to them, Demona heard the entire exchange, and believed that he would betray her. To protect her clan, she made a deal with Canmore and the English. In exchange for their deserting the castle, thus allowing MacBeth to be easily defeated by the English forces' superior numbers, her clan would be safe from Canmore and the English's wrath. Thus, her clan left the castle, and Castle Moray was conquered. Fortunately, MacBeth escaped with Gruoch, but they were confronted by Canmore and Demona, who accused MacBeth of planning to betray her clan. He vehemently denied it, and while they argued, Canmore fatally stabbed MacBeth, killing him. Demona died as well, proving to Canmore that the rumors of their being linked by sorcery were true. He assumed that when one died, both died. Canmore left Gruoch alone, having no quarrel with her and mentioned that he had smashed the rest of her clan as well. Soon after he left, Luach and Bodhe came, and saw that MacBeth was dead. Luach became the new High King of Scotland, and as he and Bodhe left, leaving Gruoch a moment in peace, the Weird Sisters appeared, and informed her that Canmore had it backwards. It was not that when one died, both died, but that while one lives, both lives, and Demona came back to life at that point. Furious at Demona, Gruoch told her that the English had destroyed her clan. Demona did not at first believe her, but she left. MacBeth revived at that point, and Gruoch told him, so that Luach would not lose his loyal Scotsmen, who would now fear MacBeth as a sorcerer, MacBeth would have to leave his old life behind. Thus began an over 900-year enmity between the two immortals Demona and MacBeth.
For the next 937 years, Demona traveled widely. She further studied sorcery and hoarded wealth. At some point, she met the Child of Oberon known as Puck. She was also hunted by numerous Hunters, descendants of Canmore, who carried on the feud, even though after a while, they no longer even knew why they did so.
In 1495, Demona started constructing a master plan for her ultimate goal- the total and utter annihilation of the human race. She believed, and still believes, that for the gargoyle race to survive; all humans must be wiped from the face of the earth. To that end, she traveled to Florence, Italy, where she picked up the Medici Tablet, which was inscribed with an incantation called the Fulfillment Spell. The spell was too powerful for her to control then, but, being an immortal, she had plenty of time to wait. As she left, she was attacked by a Renaissance version of the Hunter, but she escaped him. At some point after this, she traveled to America. In 1980 she traveled to the Notre Dame Cathedral, in Paris, France. She picked up another vital part of her master plan, the Praying Gargoyle statuette. She was attacked by another Hunter there, Charles Canmore, whom she quickly threw off the Cathedral to his death, in front of his three children, Jon, Robyn, and Jason. After this, she was introduced to David Xanatos by Owen Burnett, who had met her centuries earlier as Puck. The two formed an alliance, and she agreed to help him in his endeavor to move Castle Wyvern and reawaken the six remaining members of the Wyvern clan, whom they would control.
In 1994, the clan was reawakened. Demona hid for the first few days they were there, waiting for the right moment. A few days after they awoke, Demona revealed herself to them, and lied, saying that she had went after Goliath and was caught far outside the castle and became lost. By the time she returned, she claimed, Goliath and his clan were in permanent stone sleep, and she begged the Magus to freeze her in stone too, so that they would awaken together. Xanatos then claimed that he saw her statue and was impressed enough to put it in his private art collection. When he raised the castle above the clouds and saw what it did to the rest of the clan, he claimed, he deduced that bringing Demona to Castle Wyvern would have a similar effect. Of course, this was entirely a fabrication.
Supposedly in gratitude for bringing Goliath and herself back together, Demona convinced Goliath to have his clan "retrieve" three computer disks from Xanatos Enterprises rival Cyberbiotics. Demona and Goliath went to the Cyberbiotics Air Fortress, a massive airship, to retrieve one of the disks. Extreme anti-human actions Demona took while here, culminating in the destruction of the Air Fortress, made Goliath realize that the Demona he was with now was not the "Angel of the Night" he had known in 994, and he told her of this. This made Xanatos conclude that the gargoyles were too difficult to control. Demona was convinced of this too, and she convinced Xanatos to test the real reasons why Xanatos wanted the disks- gargoyle robots called the Steel Clan- against her former clan. The Trio of Brooklyn, Broadway, and Lexington were caught by surprise, but thanks to Goliath, the clan defeated their robotic replacements. Demona revealed her true nature, nearly hitting Goliath with a bazooka shell, and giving him one last chance to join her against humanity. He would not, and she concluded that if he was not her ally then he was her enemy. Just as Demona was about to eliminate Goliath once and for all, NYPD Detective Elisa Maza came in, and tackled Demona, throwing off her shot so that she hit a castle tower above them, which crashed down and caused both Demona and Elisa to fall. Goliath had to choose between saving Elisa or Demona, who was unable to glide due to falling rubble. He saved Elisa. Demona managed to survive, but now held a special hatred for Elisa Maza, who had disrupted her plans and whom Goliath had saved instead of her.
Her next plan against the clan was to trick Brooklyn into taking mental control of Goliath with the Grimorum Arcanorum. When her true intent was revealed, Brooklyn turned against her and, with Elisa's help, removed the spell over Goliath. She managed to tear a handful of pages from the Grimorum, spells in which she uses in the future. She later tried to poison Elisa Maza in an attempt to lure Goliath to his doom, but, unknown until later, she missed. To prevent Demona's knowing this, Hudson and Goliath came to her trap, and fell into it. Hudson protected a wounded Goliath until dawn, and the next night, he was fully healed and too much for Demona to handle. She remained convinced that Elisa was dead for a short while, but she soon learned that the detective still lived. With Xanatos, she created the cyber gargoyle Coldstone from the shattered remains of three gargoyles, with the missing parts filled in with cybernetics. The creation of science of sorcery was convinced to fight with Xanatos and Demona against Goliath and his clan for a while, but he soon changed sides, and Demona nearly killed Goliath. If Coldstone had not blocked the shot, Goliath would have died. She wished to continue fighting the clan, but Xanatos took her away from the battleground against her will.
After the Coldstone incident, Demona's plans took on a grander scale. She next stole Titania's Mirror from the Metropolitan Museum of Art, and used it to summon the Child of Oberon, Puck. Her plans regarding Puck were "misinterpreted" by him, however, eventually resulting in the populace of Manhattan being transformed into gargoyles, and Goliath's clan being transformed into humans. She attacked Goliath's clan while they were human, but she was defeated thanks to the help of Elisa Maza, who had also been transformed into a gargoyle. Goliath released Puck in exchange for restoring Manhattan to normalcy, and when Puck left, he took Demona with him, seeking to "reward" her for giving him such a good time. She simply wanted the annoying Fay to leave, which insulted him. So he gave her a wish she had mentioned earlier, that of not turning to stone by day. So he granted it- she now turned into a human by day.
She next attended Xanatos's wedding to Fox, and tricked Goliath into giving her the other half of the Phoenix Gate, which she used to transport herself, Goliath, and David, Petros, and Fox Xanatos to the year 975. She showed her 975 self the carnage of the Castle Wyvern Massacre of 994, and attempted to convince her 975 self to use the Gate to manipulate time to her bidding, but her 975 self refused, refusing to become like her 1995 self. The 1995 Demona was about to beat her 975 self into doing what she said, but the 1995 Goliath, who had been taken along to 994, stopped her. After the 975 Demona took the three back to 975, Goliath returned himself, Demona, and the Xanatoses to 1995.
Her next plan was one of her grandest in scale. She tricked Xanatos into allowing her to broadcast, on all New York City television signals, a magical spell that turned all who saw and heard it into stone at night. She then proceeded to smash all the petrified humans she found. However, she was tracked down by another Hunter, who attacked her at Pack Media Studios when she confronted Xanatos there. She managed to escape this Hunter, whom she quickly realized was actually MacBeth. The next night, Demona snuck into Castle Wyvern, where she planned to smash the stone statues of Owen Burnett and Elisa Maza, but was stopped by Bronx. So, instead, she altered a countdown sequence on Xanatos's computer. He and the Manhattan clan came up with a plan to undo her spell, which was designed to end when the sky burned. So, by gliding across the sky and spreading flammable gases in the air, which would then be set afire by exploding Steel Clan robots, the sky would temporarily be set afire. However, the explosions were set to go off after a certain time, and Demona tampered with the countdown, causing it to be accelerated so that the explosions would not set the sky on fire, but would instead kill Xanatos and the clan.
Right after she altered the countdown, however, she was confronted by "the Hunter," whom she told to reveal his true identity of MacBeth. MacBeth and Demona then engaged one another in a highly destructive battle, which Goliath, Xanatos, and then the trio of Fay sorceresses known as the Weird Sisters interceded in. A fall to the Arboretum level of the Eyrie Building knocked Demona unconscious, but the Weird Sisters convinced him to let her live, even though after over 900 years of immortality, he wanted to die. The Weird Sisters managed to convince her that much of the bad things that had happened to her were her own doing, and this convinced her to give away the pass code that would allow Xanatos to correct the accelerated countdown, the word "alone." She was not convinced for long, though, and she quickly resumed her previous mindset that humanity as a whole was responsible for her pain. The Weird Sisters then took Demona and MacBeth, and left. Afterwards, Xanatos changed the countdown back, and Demona's spell was undone.
After the Weird Sisters abducted Demona and MacBeth, the two became the Sisters' unknowing servants. They were influenced to steal the Grimorum Arcanorum, Phoenix Gate, and Eye of Odin from the Manhattan clan, and they reactivated Coldstone, allowing his third, evil personality to gain control. The three then captured the clan, and Demona revealed that she now turned to human by day to Elisa, and told her that she was at Belvedere Castle in Central Park. She gave her a choice- if Elisa came to save the clan, she would surely die. If she didn't come, Demona would use that to demonstrate the untrustworthiness of humans to Goliath before she killed him. Elisa decided to come to Belvedere Castle at high noon, and Elisa and the human Demona fought. During the battle, the primary, good persona of Coldstone was able to regain control, and he turned on MacBeth and Demona. MacBeth and Demona escaped. They returned to MacBeth's manor, where the spell began to wear off and their animosity towards one another began to manifest once more. Before they could attack one another, however, the Weird Sisters paralyzed them; picked up the three mystical talismans they had stolen, and took them, once more in their thrall, to the watery gate of Avalon.
They were given to the Archmage as his puppets, and he used them to attack the Avalon gargoyles. When Goliath was brought to Avalon to help, he made an appeal to their better natures, briefly breaking their enchantment, but the Archmage simply reinforced it. Demona single-handedly wounded a large number of the Avalon clan's members while enchanted, but she was eventually taken out by Princess Katherine using Demona's own laser cannon. Goliath forced the Weird Sisters to remove their spell on Demona and MacBeth, and they were sent adrift into the mists of Avalon, with no recollection of anything they had done while under the Sisters' spell. They appeared in Paris, France. There, Demona met Thailog, a clone of Goliath with a Xanatos-like outlook on life, and, as she said, it was "love at first flight." She began using her daylight humanity to her advantage, creating the human identity of Dominique Destine. She and Thailog concocted a plan to gain a large amount of wealth from MacBeth. As Dominique Destine, she began romancing MacBeth, who used the identity of Lennox MacDuff. She eventually became engaged to be married to him, and they were to be married at about the same time Goliath, Angela, Elisa, and Bronx appeared on their Avalon journey.
The Avalon travelers became entangled in the plan, and managed to help stop it, although Demona did manage to marry MacBeth. Unbeknownst to her, Thailog planned to have MacBeth and Demona kill one another, so that he, as Demona's sole business partner, would inherit both Demona's and MacBeth's wealth. The two did try to kill one another, but Demona was temporarily killed by Elisa using one of MacBeth's electron discharge guns. Elisa did this to prevent them from killing one another and so that Thailog's plan wouldn't succeed. Demona briefly got a glimpse of Angela, who, though she didn't know it yet, was hers and Goliath's daughter. As soon as she did, though, Thailog picked her up and the pair left, for Demona did not yet know of his treachery. During the fiasco in Paris, Demona and Thailog (in their guises of Dominique Destine and Alexander Thailog, respectively) combined their wealth to form a new corporation, Nightstone Unlimited. They also discovered that Angela was the daughter of Demona and Goliath, and Demona began composing a plan to convince her daughter to join her side.
For the next 937 years, Demona traveled widely. She further studied sorcery and hoarded wealth. At some point, she met the Child of Oberon known as Puck. She was also hunted by numerous Hunters, descendants of Canmore, who carried on the feud, even though after a while, they no longer even knew why they did so.
