This is a character that's somewhat personal to me. Her name is Virexia. She's a toxic green acid, turning black/purple when she feels attacked. She shuts herself off, doesn't hear, doesn't see, and is only on the defensive. Her hair covers her eyes because at that moment she wants absolutely nothing to do with anything and attacks anyone who approaches her. As soon as her Kalmora state (black/purple) passes, she becomes a blue puddle of shame (Blüme state).
She doesn't speak.
She has to change by making her feet non-toxic, because when she walks she would melt everything; if her feet are non-toxic, her "arms" are.
