1. Demona, Gargoyles
Background: Once a member of the Gargoyles clan, Demona’s deep hatred of humans led her to betray the castle and its inhabitants that she was sworn to protect, by letting it be raided by Vikings. The raid caused the murder of her entire clan (except for a few survivors who were put under a sleeping spell). Demona spent the next 1,000 years amassing a great fortune and plotting her revenge.
Villainous threat level: 10 out of 10. Demona might be Disney’s greatest anti-hero in any genre. Her deep need for revenge drives her to make several attempts at exterminating the entire human race, but unlike most villains the motives for her actions aren’t driven out of evil, but rather for a greater good for her species and her love of Goliath.
