Ivy is the Ultimate Toxicologist. She is a researcher, as she's created poisons for herself as well creating antidotes and solving mysteries behind numerous disease. She grew up always discovering things along with her younger brother. She's especially taken a liking to plant's natural poisons and toxins. She means well but comes off as a sort of toxic person. Her mind speaks for itself, but she knows her limits. 

Ivy's Voice should be a Medium-low tone (although any is fine) There should be a bit of sass behind her voice too.
