|Portrayed By||Kathleen Munroe|
|First Seen||Original Sin|

|Also Known As||
|Family||Lee Rosen (father)|
|Alpha Type||Empathetic Contagion|
Danielle lived with her father for most of her childhood, with Dr. Rosen realizing the nature of her Alpha ability at age nine. She characterizes those years as possibly abusive, as her father manipulated her into using her powers on her mother, who was considering leaving Lee. Her empathic powers also allow negative emotions from nearby people in, keeping Dani in a fairly constant state of pain. Running away at an early age, Dani coped with her Alpha power by self-medicating with opiates and anti-convulsives.
Dani is a Caucasian female with long brown hair and a slender build. She generally has an expression of pain and sorrow.
Dani's Alphas ability allows her to share sensations or emotions with other people, either by augmenting mutually shared emotions or exercising control over others by forcing emotions onto them. After using her power, she has a feeling of pain. On the show, the visual representation of Dani's power is little blue circles of light travelling from her hands onto other people.
In "Original Sin" her middle name was "Sophia", yet in "Life After Death" it was "Sarah".
