Most Anomalies gain their powers with the onset of puberty, usually around twelve or thirteen. The same may have been true for Abby Johnson, but nobody realized it until she was fifteen -- when a bicycle crash left her with a badly-scraped elbow... which quickly healed over into thick, heavy moonstone film that was considerably more damage resistant. An accidental cut while opening a box resulted in a scar of similar consistency across the palm of her hand, and it was shortly after that her pediatrician realized that her growth wasn't following normal patterns and started doing more tests. The results left Abby quietly terrified: her body was changing, she couldn't control it, and she had no idea where -- or if -- it would end. She was slowly becoming a monster, but any time she got injured the wound rapidly accelerated the process. 

Abby takes shelter in her music; she plays drums and bass with a few other students in a band they call The Mass Casualties, but she also listens to music almost constantly, either for relaxed enjoyment or to pick it apart and see how it all fits together. She enjoys strategy games for the combination of challenge and socialization, and is good at math in a way that she thinks is normal but most people find quite impressive. She gets her exercise from running track -- mainly as a sprinter -- and hiking, and has recently expanded into bicycling and swimming. She's a decent but not exceptional student, and struggles with her language classes (including English).
