------------------------------
Mary is a fairly large golden-scaled naga mage. She has highly-trained magical skills, and isn't afraid to use them when people annoy her. Of course, being part snake also gives her the option to just gulp down her enemies!
Mary can use her magic to change her form, but the form she changes to must always be either part snake or part human. For instance, she can change her body to a full snake, an anthro snake, a human, or even a neko (human with cat's ears), but not into an anthro cat.
Mary is very unwilling when it comes to being prey, and will do almost anything to keep herself alive, and eat her predator for revenge. This could be anything from a simple teleport to a full-on magic battle. The only way to truly devour her is to cut off her magic power entirely. This can be done with lavender. She's highly allergic to the stuff, and it makes it hard for her to move and impossible for her to cast spells, which essentially just leaves her as a big, meaty noodle if her pred's big enough!
Victims
Kimiko_Suzuki refused to allow her to sit down on a park bench, and is now living out the rest of her life as a beautiful golden necklace strung around Mary's neck.
Destoplayer climbed into giant anthro Mary's mouth whilst she was asleep to get his camera back out of her belly. He didn't come back out again.
Perdix met her in Nexus Park, and although she initially planned on eating him, she wound up befriending him and ultimately letting him go after he reformed.

Victimisers
Sara_lina met Mary out in the forest and ate her, but while she sat there inside the bigger naga's belly, they got to know each other and became strong friends!
