The Shadow Sirens are three witches in Paper Mario: The Thousand-Year Door. They consist of Beldam, Marilyn, and Vivian (later replaced by Doopliss). They aid Sir Grodus and the Secret Society of X-Nauts in their quest for Crystal Stars and retrieve the Magical Map from Mario and his friends. After Vivian joined Mario's team, Doopliss took her place.
Beldam, the leader of the Shadow Sirens, is often forgetful, and on more than one occasion, her forgetfulness gets Vivian in trouble. She is more of a magic user than the other two are. Marilyn is the biggest and strongest Shadow Siren in the bunch. Other than one line, "The Three", she is unable to say more than "Guh", and various forms of it. She can become stronger and hit hard. The Shadow Sirens are fought twice in the game. Beldam was the merchant from the intro of the game, as when Sir Grodus is talking to the 3, he asks Beldam why she didn't kidnap Princess Peach when she had the chance. Also near the end, Beldam says to the Shadow Queen "I spread rumors of the treasure and found a pure-hearted maiden."
Paper Mario: The Thousand-Year Door
They were first sent by Grodus to ambush Mario, Goombella, Koops, and Punio in Boggly Woods and retrieve the map from them, but Mario and co. weren't able to battle them because they were missing the picture of Mario. When Mario and co. learned that they stole Flurrie's necklace, they fought them to get the necklace back. After their defeat, they dropped the necklace.
While Mario, Goombella, Koops, Flurrie, and the Yoshi were searching for the Ruby Star in Creepy Steeple, they planned to use an explosive item called a Superbombomb against them. Beldam blamed Vivian for losing the explosive. Mario, after Doopliss stole his appearance, found the item for Vivian and she joined the team, not knowing the person who helped her was Mario. After Mario and Vivian defeated Doopliss, Doopliss took Vivian's place in their nefarious group.
After Mario, Goombella, Koops, Flurrie, the Yoshi, Vivian, Admiral Bobbery, and possibly Ms. Mowz cleared Chapter 5, Beldam, Marilyn, and Doopliss were sent to find the Garnet Star in Poshley Heights. No matter the costs, Beldam, Marilyn, and Doopliss had to prevent Mario and his friends from reaching the Star during a three-day train trip aboard the Excess Express. They first stole a Businessman's briefcase, Toodles' Gold Ring, and the waitress' shell earrings, and planned to mix them together to bomb the train with Nitro Honey Syrup, thus resulting in a sticky, yummy, gooey mess. Beldam and Marilyn even had Doopliss disguise himself as Zip T., a pop star, so that way nobody will suspect they committed the crime, and frame Zip T. for the crime. Before putting their evil plans into fruition, Mario and his friends, with Pennington's help, managed to crack the case and return the briefcase, the shell earrings and the gold ring to their rightful owners. Since their Nitro Honey Syrup bomb idea failed, they used an alternative - they ordered Smorgs to raise the drawbridge at the Riverside Station to stop the train from going far, but Mario and his friends managed to fend off the Smorgs and lower the drawbridge. During Day three of the train voyage, the Smorgs stowed away onto the train, attacked it, and took passengers hostage. Mario and his friends beat the Smorg and made it to Poshley Heights. When Mario and his friends reach the Poshley Sanctum, they discover Beldam, Marilyn, and Doopliss beat them to the Garnet Star, but eventually, Beldam, Marilyn, and Doopliss discovered the Garnet Star they grabbed was a red herring - a fake.
While Mario and his friends were venturing through the Palace of Shadow, the Shadow Sirens ambushed them again and after Mario and co. defeated them, they continued on to stop Grodus from awakening the Shadow Queen. After Grodus awakened the evil queen from her eternal rest, getting destroyed in the process, Beldam took full credit for the awakening of the queen. In fact, it turns out the Shadow Sirens tricked Grodus into awakening the Shadow Queen. At the very end of Mario's adventure, Beldam and Marilyn tell Vivian they'll never be mean to her again.
