Claire Winningham
Timeline of Events:
2004: Claire appeared as the gift for
December 9, 2004. While 2002 had shown multiple Mare Sisters, the current cast didn't know about the clones. Claire was revealed to be #89, and claimed that she isn't as evil as the murderous clones despite still wanting to cause some mischief.
Mare dubs her as Claire, and details the story about how the first Mare was beaten to death hence the ingrained violent tendencies. These are found to be more extreme that she first let on, and convinced Waiterbot to form Team Evil after providing him with a new body. She doesn't succeed though and when Santa appears, he traps her in ice since Santas are no longer allowed to outright kill people.
2006: Claire remained trapped in a cylinder of magic ice, but was able to mind control
The Boss into kidnapping the heroes' wives. After
Santa 2005 showed up and killed The Boss, he instructed them to take Claire home and watch over her.
Mare II was born on the 20th and the telepathic link allowed her to free Claire so she could finish off the season as the main villain.
