Simone Lenoir

"Very clever Velma. But it's too late."

- Simone Lenoir's most famous quote while revealing her true nature.

Simone Lenoir is the main antagonist of the 1998 direct to video Scooby-Doo film Scooby-Doo on Zombie Island. She was a woman who was actually an immortal werecat who lived on Moonscar Island with her friends Lena Dupree and Jacques, who are also immortal werecats. Every harvest moon, she must drain the life force of victims lured to the island to preserve her immortality. She was also Beau's former boss.

She was voiced by Adrienne Barbeau, who also voiced Catwoman.

Past
The human Simone Lenoir lived in the 18th century, born in the late 1690s, and was one of a group of peaceful settlers who lived on Moonscar Island and worshiped a cat god. One night while the settlers were celebrating a bountiful harvest, the island was raided and pillaged by Morgan Moonscar and his pirates; the pirates drove all the settlers except Simone and Lena Dupree into the bayou, where they were devoured by alligators. Devastated and vengeful for what Moonscar's pirates had done to their friends and their home, Simone and Lena invoked the cat god to curse the island and give them revenge upon the pirates. The cat god granted their wish by transforming Lena and Simone into werecats, who subsequently killed Moonscar and his pirates.

However, this was not the end of it for Lena and Simone, as they afterwards found that the cat god's curse had turned them into werecats permanently, cursed to live forever through draining mortal victims' life energy every harvest moon. So for the next two centuries, Simone and Lena would, every harvest moon, drain the life energy of Moonscar Island's human inhabitants; if there were no others on the island at the time of the annual harvest moon, Simone would have Lena find and lure tourists and visitors to the island to drain. A side-effect of the werecats draining their victims' life energy was that it would curse the victims' souls so they would rise as zombies every harvest moon and unsuccessfully try to warn the annual victims off from suffering their fate. Lena and Simone also at some point recruited Jacques as their ferry driver for bringing lured victims to the island, and granted his wish for immortality by passing the were-cat curse onto him.

Encounter with the Mystery Gang
The werecats' latest to-be victims in the present were Mystery, Inc. when the gang were lured to Moonscar Island by Lena in Daphne Blake's search for a real haunting for her TV show. As the gang settled in, Scooby-Doo caused a destructive pursuit of Simone's cats all over her property and it was a running irritation for her.

Revelation and Death
On the night of the harvest moon, when the zombies of the werecats' previous victims rose and went after the gang to try and warn them, Lena lured Fred, Velma, Daphne and the human gardener Beau to her and Simone's underground voodoo dungeon so that the zombies would not interfere. The werecats captured and bound them using voodoo dolls to be drained. The gang managed to slip free before Simone and Lena could drain them, in the commotion when Shaggy and Scooby, followed by Jacques and the zombies, fled into the dungeon. Lena and Simone almost succeeded in draining Shaggy and Scooby, but were stopped when Velma and Daphne reconfigured the voodoo dolls and used them against the werecats. Jacques, Simone and Lena eventually overcame the zombies' efforts to stop them and cornered the gang to drain them, but just then, the midnight phase of the harvest moon ended. With the harvest moon's midnight phase having ended before the werecats could drain their victims, Simone, Lena and Jacques' immortal lives were taken away and they decayed away and perished; ending the cat god's 200-year-old curse, and freeing the souls of the werecats' zombified past victims to rest in peace once and for all.

Trivia

 * Simone and the other werecats are the first Scooby-Doo villains to die, followed by the Phantom Virus. Although both Sarah Ravencroft and Ben Ravencroft were seemingly killed when their spell-book was burned, this doesn't specify their fates, as they were never confirmed officially to have died when the book was burned.
 * Simone appears to be similar to Count Dracula, winning the protagonists over with her mannerisms, lowering their guard before ultimately revealing her true nature and attacking them. The only difference being her temper.
 * Simone is based on Elise Lenoir from the Jonny Quest episode Eclipse, who in turn was based on Katrina Moorkroft from the unfinished SWAT Kats episode Succubus!.
