Marcie Fleach, also known as Hot Dog Water or the Dark Lilith, is a major villainess-turned heroine in 2010 animated horror television series Scooby-Doo! Mystery Incorporated. She a friend and former rival of Velma Dinkley (Mindy Cohn). Her cruel and nasty nickname supposedly comes from smelling like recycled water used to cook hot dogs. She is voiced by Linda Cardellini.


Marcie is a scrawny, oily skinned, pale teenage girl with long, greasy, tangled auburn hair and purple eyes, her nose is also perked up constantly. She a wears dirty, crinkly cardigan with a yellow shirt and red cravat along with an equally crinkly red frilly skirt and matching red shoes along with striped knee high socks underneath.


Marcie was full of resentment, envy, bitterness, and distaste for everyone around her as a result of being an outcast. She had a rather cold, nasty, and bitter demeanor until she was offered a place in Mystery Inc. where her personality was expanded to be that of a sarcastic, vain, cynical girl who had a rather no nonsense attitude to live, unlike Velma. Velma was the person Marcie cared about the most and this care later expanded to the rest of Mystery Inc. as shown when she sacrificed herself to save their lives. Aside from her flaws and negative traits Marcie was an unexpectedly intelligent individual only rivaled by that of Velma's intellect.

She was known as the weird girl at Crystal Cove High School and had no friends at all. Only appearing as a minor character for a fraction of season one she eventually was featured prominently under the disguise of Manticore where she attempted to steal the steel from roller coasters in order to make profit resulting in her being imprisoned.

Joining and leaving the Mystery Inc.[]

After being released from prison, she joined Mystery Inc during Daphne Blake's absence and made a bond with Velma who she became very close with. This happiness was short lived however as she was kicked out of the gang upon Daphne's return.

She and Velma remained good friends however and Marcie joined Mr. E (Lewis Black) and worked for him under the disguise of Dark Lilith in order to search for a piece of the Planospheric Disk. After being unmasked by Velma she decided to give the disk to her and was sure that she would avoid punishment with her skills. Velma then requested her help in stealing the remaining pieces of the disk.


After this she was used to blackmail Mystery Inc into assisting Professor Pericles (Udo Kier) in opening several portals, Marcie broke free however and grabbed Pericles, threatening to kill him and telling the gang to leave without her she backed away from the robots still vocally threatening Pericles and pulling his feathers off.
