Marilyn

Marilyn appeared in 2004 video game called Paper Mario: The Thousand-Year Door. Marilyn is one of the three Shadow Sirens and the middle sister of the older Beldam and the younger Vivian (who is later replaced by Doopliss). She and her sisters work alongside the X-Nauts to find the seven Crystal Stars and open the Thousand-Year Door. Marilyn and her teammates appear several times throughout Mario's adventure in Paper Mario: The Thousand-Year Door, making numerous attempts to slow him and his partners down and hinder their progress.

Marilyn, unlike her teammates, happens to be very quiet, and is never or rarely ever seen talking. She's often described as the "strong, silent type" by Goombella. The only words she speaks are, "The Three..." while she and her sisters are introducing themselves to Mario and company. Otherwise, she makes "Guh" sounds and variations of it. Despite this, Beldam usually understands what she's saying, or at least what she's trying to say. Marilyn is shown to be very loyal to Beldam, as she often follows whatever orders are given to her without question. Because of that, Marilyn is the "favorite" of the group, as Beldam treats Vivian and Doopliss with as little respect as possible.

Powers and Abilities
Marilyn specializes in powerful lightning magic abilities, as reflected by the yellow stripes on her hat. She also has the ability to charge her attack power by two various times, and if the player does not stop her, then she can double or triple her already-high attack power, potentially causing an instant death. As with her sisters, Marilyn knows how to use the Veil ability, allowing her to sink into the shadows. She uses this ability to hide and teleport, but she does not use it in battle.
