A treasure hunter who loves jewels, especially the Chaos Emeralds. Due to this, she has found herself fighting against both Sonic's team and Eggman's team, though she tends to side with Sonic most of the time. Her treasure hunting ways have made her a rival to Knuckles, guardian of the Chaos Emeralds. Though confident in her abilities (and a skilled fighter), she knows when to escape, and also knows that fighting is not always the answer.
