is the Gym Leader of Mistralton Gym and those that defeat her in battle are given the Jet Badge. Her grandfather explained to Ash Ketchum
and his friends that Skyla
is such an amazing battler that challengers from all over the Unova region came flooding in to battle her but she became so busy that she couldn't fly her beloved airplanes any longer. She then devised air battles to save her time battling against all the challengers as she efficiently judged the challengers and their Pokémon by doing simulated battles in her head. If they won the simulation, she would award them the badge.
Gym Battle against Cilan
After watching Skyla
perform 'air battles', Cilan
got very upset that she was not actually doing the battles and he challenged her to a battle. Cilan
agreed to do an 'air battle' with her and she determined that he would loose the battle against her with the Pokémon he had chosen to battle her with. Cilan
though wanted to have a real battle with her a he explained to her that with Pokémon battle, like any meal, must be tasted first before people can be certain to know anything. Skyla
agreed and Cilan
thought that he would be able to show her up by defeating her in a real battle and showing how her 'air battles' are flawed. Unfortunately Cilan
ended up loosing to Skyla
but Ash Ketchum
challenged her to a battle right after.
After the crowd and her grandfather convinced her to battle against Ash Ketchum
did an air battle against Ash Ketchum
's selected Pokémon and she said she'd beat him. Ash Ketchum
wanted to battle her right away after hearing that but she told him she'd battle him at noon the next day. Ash Ketchum
was able to prove to Skyla
the efforts of a Trainer and their Pokémon can bring about unexpected developments that her air battles couldn't account for. She then agreed to do proper Gym battles instead of air battles from that point on.
