Hot Dog Water was sent to prison for trying to close down an amusement park, but was released early and went to work for Mr. E. During that time she befriended Velma and gained membership into Mystery Incorporated as a mole, temporarily replacing Daphne. She was forced to leave the gang when Daphne returned, but continued working for Mr. E. When she was sent to Mount Diabla to retrieve a piece of the Planispheric Disk, she instead handed the piece to the gang because she couldn't betray Velma, her only friend. Though Hot Dog Water went into hiding after turning against Mr E., she helped Mystery Inc. infiltrate Mr. E's vault and steal his pieces of the Planispheric Disk.
Hot Dog Water was eventually captured by Professor Pericles, who used her as a hostage to force Mystery Incorporated to help him open the four gates and gain access to the Crystal Sarcophagus. She turned the tables on Pericles so the gang would be able to reach the sarcophagus first and destroy the Evil Entity trapped inside it, but she was shot to death by the Kriegstaffebots in the process.
After the gang reset history, Marcie was Velma's closest friend (outside of the Mystery Inc. gang) and science partner, who she still affectionately refers to as "V."
Marcie is a skinny teen-aged female with brown hair, which is usually very messy, in loose oily waves held back with plastic barrettes, and wears red-rimmed, armless glasses with yellow lenses. She originally wore a tan hoodie with a white t-shirt underneath, before changing to a brown wool jacket. She also wears a red skirt, striped socks and matching red shoes.
Marcie has a very no-nonsense personality and shares many of her traits in common with Velma, such as skills with computer infiltration and research.
Originally, she was very competitive with Velma, the two sharing a mutual strong disliking of one another and a rivalry in the science club. This changed, however, when they bonded after both working together for Mr. E and realized how ridiculous their rivalry was. When she got cruelly kicked out, Marcie became sad and lonely, yet was still loyal towards Velma and thought of her as a friend and vice versa.
She affectionately refers to Velma as "V" after befriending her, indicating she can be a very loyal person despite her cold personality. It is also implied that she has feelings for Velma as well.
Skills and abilities
She is good with computers, a brilliant amateur chemist, and apparently a not-inconsiderable gymnast given her infiltration of Mr. E's Destroido base, and her uses of the Manticore and Dark Lilith suits.
She had competed with Velma in the science fair circuit more than once, and lost every time.
Scooby-Doo! Mystery Incorporated
She attacked people at Creepy Spooky Terror Land in the guise of the Manticore in order to shut it down so she could use the steel in the rides to make super-helium and get rich. (Her father, Winslow Fleach, owned the amusement park).
She claimed she was released early from prison because she improved the computer system there to be more harsh towards inmates. This may not be the whole truth; Mr. E likely had something to do with it as well as he was the one who bailed her out as he had Alice May.
She was kicked out of the gang after Daphne came back, despite Velma's protests. Upset, she went back to working with Mr. E, revealing she had been placed as his mole, but showing some trepidation about her role.
Mr. E sent her to Mount Diabla to search the Spanish Galleon there for its piece of the Planospheric disk. She disguised herself as the Dark Lilith to lure the gang to the mountain and get past the traps for her. However, the triggering of the many traps destabilized the centuries-old galleon, and in the ensuing chaos, she was trapped in wreckage, whereupon Velma unmasked her.
Revealing her plan, she decided to give the disk piece to Velma, rather than return it to Mr. E, despite knowing the ramifications of the betrayal, and confident that her skills and the Dark Lilith costume would be enough to keep her ahead of him.
Velma later enlisted her to help steal the Planospheric Disk pieces that Mr. E and Prof. Pericles had acquired. Marcie's job was to infiltrate Mr. E's vault and grab the pieces while Jason Wyatt kept him distracted with the Krampus robot.
She was somehow captured by Pericles and cruelly locked in a trunk and taken down to the caverns below Crystal Cove, where she would be used as a hostage to force the gang to open the inter-dimensional portals for him. She managed to grab Pericles as a hostage after the Air door was opened, and heroically demanded the gang go forth and destroy the evil Nibiru entity while she held the old Mystery Incorporated in check. Machine-gun fire is heard in the distance by Velma and Scooby later, indicating that Marcie was gunned down by the Kriegstaffebots at Pericles's order, making the ultimate sacrifice to buy Mystery Inc. the time they needed.
When the gang created an alternate timeline with no influence of the Evil Entity, Marcie was alive and she and Velma were a team and win every year at the Tri-state Olympiad of Science. Marcie's feelings for Velma were also more affectionate in this time, as she happily referred to Velma as "[her] girl".

- Her voice actor Linda Cardellini played Velma Dinkley in the live-action movies Scooby-Doo: The Movie and Scooby-Doo 2: Monsters Unleashed.
- She is allergic to gluten. (The Dragon's Secret)
- The super-helium may be a reference to the old Disney movie with "Flubber" gas, Son of Flubber.
- She is the second character in Scooby-Doo! Mystery Incorporated to wear two disguises, the first being Alice May.
- She is one of few characters to have been killed in a very graphic manner; her death was by gatling gun, similar to most Johnny Quest villains.
- Much of Marcie's design is meant as a contrast to Velma's Mystery Inc design, to indicate a sort of "second-rate Velma":
- Her glasses are armless, with yellow lenses.
- She wears a sweater that fits poorly and is made of itchy wool.
- Her hair is oily, wavy, and long, and held in place with plastic barrettes instead of bows.
- She is very slender, compared to Velma's traditionally being depicted as more rubenesque.
- Velma alone refers to her by her given name of Marcie; even after she is befriended by the rest of Mystery Incorporated, who continue to refer to her as "Hot Dog Water."
- It had been speculated that Velma and Marcie's relationship could be a romantic one and cast member Grey DeLisle has referred to Marcie as Velma's "girlfriend" in interviews.
