Kamryn/Introduction
Before P-day, Kamryn was a man of more or less average height and thin build - not unhealthily thin or from diet and exercise, just the result of a fast metabolism meaning he wasn't carrying any excess weight. As a child his hair was light blond, but over time it darkened to a colour that was more of a dark ash brown, always kept in a simple close-cropped style chosen in equal parts for its neat appearance and ease of maintenance.
Following the events of P-day, Kamryn managed to avoid any major mutations for around a decade through use of RSX's anti-nanite inoculations and avoiding contact with most of what remained of civilisation. Whether from the nanites or a side effect of the inoculations, he did experience minor changes - while he never had the most masculine physique he gradually shifting towards a much more androgynous appearance, as shown in his RSX ID photo. He didn't consider this a problem though as the same effect seemed to keep him looking a little more youthful than his real age would suggest.
In 2018 he mutated into the form of a latex skunk, and also became physically entirely female. Kamryn began identifying as female shortly after as he became more comfortable with his new shape, and while a skunk would perhaps not have been her first choice for a anthro form, she is now rather fond of her pale purple tinted stripes, and she's always been rather attracted to the look and feel of latex.
