Robin is a young girl that has short light brown hair with spikes at its edges. Her bangs have a rather spiky appearance. Due to her possessing a Bravery soul, she wields a fearless attitude and will never hesitate to hurt anyone when necessary. She also seems to be good-hearted, putting herself at risk to save others. A good example of this in Do or Die, when she stays in Toriel's school in an attempt to save people from being killed by Bete's army of Kumulings.
