Very much a cyborg, her implants permanent discernible evidence of her time as a Borg drone — a consequence of both the lengthy amount of time she spent as one and having 'grown up' within the confines of a maturation chamber. Most of her skeletal structure was plated and/or fused with metal, if not metal in its entirety. Her brain was more like a computer's than a living beings in some areas, and she could not survive relying solely on her biological systems alone.

The Enterprise has become a hotspot of transdimensional activity, and it is highly unlikely any of the 'travelers' are responsible for the disruptions in the time-space continuum."
