Maylene made her debut in Lost Leader Strategy! where she decided to quit the Gym after she lost her Gym Battle with Paul and her confidence. She ran away from her duties. Dawn felt the same way she did and inspired her not to give up. She then requested that she have a Gym Battle with her.
In Crossing the Battle Line!
Maylene had her battle with Dawn. The plan for Dawn was to lose yet
give it her all to get Maylene's confidence back. When the first battle
began Maylene copied the moves her Pokémon used as she was giving the
orders to do so (She said and did a Drain Punch attack just as her
Meditite did). She knocked out her Buneary but lost to her Piplup.
Maylene then pointed out that Dawn treated the battle like she did a
contest. During the battle between Piplup and Lucario, Maylene was
starting to get back in synch with her Pokémon. She beat Dawn and got
her confidence back.
