Ailey is a middle-aged woman with long, near waist-length dark reddish-brown, which was often tied back with a headband, and emerald green eyes. She was last seen wearing a red long sleeve plaid shirt-jacket over a white shirt, blue jeans, and dark red boots. She wore her gold wedding ring on her left hand.
Ailey was a kind, gentle and friendly woman with a passion for legends. She was a loving and doing, mother, wife, and sister. When she was working, she would be so in her job that she would sometimes forget to care for herself. There had been times when Dallas found her passed out from working too much.
Ailey has a bad habit of working too long and much resulting in her passing out.
Ailey's Meowstic is her only known Pokémon. Having raised since he was an Espurr alongside her own sister's Espurr.
Arcanine is one of Ailey's Pokémon. Not much is known about Arcanine, only that Ailey had him when she vanished.
Ailey was born in Anistar City and is the younger sister of Corrine Walker. The two grew up doing everything together. When it was time for their journey, despite not having a decision on what to do, Ailey followed her sister on her Pokémon Journey. It wasn't until they saw the temples of Unova's Legendary Pokémon Zekrom and Reshiram, did she start to work to become a Pokémon Professor.
Eventually, Ailey returned to Kalos to continue her studies while her sister went on to travel through the regions. While she was home, Ailey met a younger trainer name Dallas Montgomery who had just come from the Alola region. They began friends that eventually blossomed into love. They later married and had two children, Caleb and Scarlett.
However, when Scarlett was three and Caleb was nine, Ailey was in Sinnoh doing studies on Dialga and Palkia and the Lake Guardians, Uxie, Mesprit, and Azelf when she suddenly went missing. With her sudden disappearance, Dallas returned to the Police Force to try to find out what happened. His return also had him returning to do what he used to do in the past: working with the Pokémon Hunters, but this time he worked undercover.
