Hot Dog Water
Marcie Fleach, better known with her cruel nickname, Hot Dog Water, is a student at Crystal Cove's High School as one of the best students, smart as Velma with a big love to science. She was once the Manticore, that was caught by the Mystery Inc, but for fixing the protection systems in prison she was released earlier and when the gang split up, she teams up with Vema working for Mr. E. A friendship grows between the two, until the gang is back and (later) Daphne joins it too, kicking Hot Dog Water out of the Mystery Incorporated, so she continues working for Mr. E trying to bring Velma to her side against the other four!
