Biography
As a child, due to her breaking her arms from a bad accident, Crystal began using her feet to catch Pokemon as a substitute for it. She trained at Mt. Mortar to do so and according to Toukai, most of Crystal's party was caught her. This was mainly because of the fact that Arcy, the first she met at Mt. Mortar, was injured by a Larvitar. She tried to help it out, however, Archy became annoyed by her and pushed her away. Unable to truly help herself, a Parasect walks up to her and helps heal Arcy. The other Pokemon that she catches shortly afterward do the same and heal Arcy back to full health. Shortly afterward, the Larvitar that hurt Archy appears. By using her new friends, she is able to defeat Larvitar and win their trust. She catches them all and keeps them with her since that point on.
