Demona

Demona is one of the primary antagonists of the animated television series Gargoyles. She is voiced by Marina Sirtis.

Demona was once Goliath's lover and second-in-command of the Wyvern Clan. She is now consumed by a hatred of humanity, and has attempted several times to destroy it.

10th century
Demona was a member of the Gargoyle clan at Castle Wyvern, Goliath's mate and second-in-command. The two mated and would eventually have a daughter, Angela, that will join the Manhattan clan 1000 years into the future. Prior to that, she had secretly studied with the Archmage and had developed an aptitude in sorcery. Demona also possesses excellent combat skills with a variety of weapons, most notably a lazer cannon, one of the only Gargoyles to use modern weaponry. Like all members of the clan (save Goliath), Demona originally had no formal name.

Resentful of human prejudice toward her clan, Demona conspired with the Captain of the Guard to betray the humans inhabiting Castle Wyvern to the Vikings; Demona failed to get the Gargoyles away from the castle, however, her end of the bargain, and the clan was slaughtered during daylight. Demona abandoned the castle, returning only to find the six survivors, including Goliath, under the stone sleep curse.

Thousand-year interim
Alone for several years, Demona has an encounter with a child named Gillecomgain, (based loosely on Gilla Coemgáin of Moray), scarring his face during a petty theft. Gillecomgain becomes The Hunter, a mercenary and assassin seeking revenge against her. Demona allies herself with a young Macbeth to kill Gillecomgain.

Later, old and weakening, Demona enters into a bargain with Macbeth. Macbeth wants a pact to protect his kingdom from his cousin Duncan I of Scotland, and Demona wants her youth back so she can lead the last of her kind. The pact is facilitated by the Weird Sisters, with several side effects: pain felt by one is shared with the other, and both are immortal until one kills the other.

Macbeth himself soon comes to admire Demona's combat prowess, and eventually becomes heavily dependent on Demona's clan for air support in the war with Duncan's forces. In the final battle with Duncan's forces, Demona's devastating attacks so impress Macbeth, he exclaimed "You fight like a demon!" After becoming king, Macbeth calls her "Demona" (She-Demon) for the first time, a name she finds very pleasing, and simultaneously declares her as his primary adviser.

Eventually, Demona's trust in Macbeth evaporates (after overhearing MacBeth considering on betraying her to win the support of the English), and fearing that he will betray her, she abandons his forces to Duncan's son Canmore and the English armies. Canmore, in turn, betrays her, killing the last of her clan.

Demona would not enter into another alliance with a human for almost a thousand years without the help of a Timedancing Brooklyn. During the intervening time, she amasses a substantial fortune, all the while being hunted by Canmore's descendants, who take up the mask of the Hunter.

In 1920, Demona would encounter Fiona Canmore in Paris, France. This event would have been seen in the unfinished Team Atlantis series.

20th century
Some time before 1994, Demona allies herself with David Xanatos, telling him about the spell put upon Castle Wyvern. This leads Xanatos to bring the castle to Manhattan, waking up Goliath and the rest of the clan. However to her outrage despite her and Xanatos' efforts to manipulate them, the Clan refuses to join her vendetta and actively opposes her. Demona tries several times to get her revenge on humanity, attempting to purge New York City ("City of Stone") and eventually the entire world of humanity ("Hunter's Moon").

Demona is also granted a "gift" by the magical being Puck: after requesting that he make her able to walk in daylight without turning to stone, he arranges that Demona transforms into a human during the day ("The Mirror"). The transformation is incredibly painful and hurts Macbeth when he is in proximity. Though initially furious at Puck's trick, she realized the positive uses of her human form and she later took up the alias of Dominique Destine, the CEO of Nightstone Unlimited, a company that she formed using her immense fortune and resources that she accquired over the years. She allied herself with Goliath's evil clone Thailog to first, steal Macbeth's fortune, and when faling that, creating their own version of the Manhattan Clan. Though, the ever treacherous Thailog had other plans and betrayed her.
