Lenora is the former Gym Leader of the Nacrene City Gym and an archeologist. She served as the Normal type Gym Leader in Black and White, but stepped down from her duties in the two years before Black and White 2 to focus on her duties as curator of the Nacrene Museum. Trainers that defeated her were given the Basic Badge.

In Pokémon the Series, she met Ash Ketchum and his friends at the Nacrene City Museum where she arrived to help figure out the mystery behind the mysterious poltergeist that was scarring Hawes. She agreed to battle Ash Ketchum after she solved the mystery of Yamask's mask.

The Nacrene Gym is located inside the Nacrene City museum and Lenora also works as the curator of the museum itself. She runs an archive full of valuable books and research papers that ordinary people are not permitted to view without her permission. Only people who want to use it for examinations, research and Gym matches can use the book archive. The library in the museum that Lenora runs has the most books in the Unova region.

Lenora tests her challengers as soon as they enter the archive area. She suggests a book to each of them that leads them straight to the underground battlefield but most decide to read up on a subject they are proficient despite the fact that she is actually showing them the shortest route to the Gym. Ash Ketchum's straightforwardness did exactly as Lenora suggested, and he picked the book that revealed the stairs to the gym right away. Most challengers read too much into her actions and end up taking a detour.

In her first match against Ash Ketchum she defeated him by studying him and getting to know his tenancies. She revealed her two Pokémon, Lenora's Lillipup and Lenora's Watchog, before the match so he could study them as well. In the end, Lenora's studying of Ash Ketchum proved to be the turning point in the match and she was able to defeat him. She told Ash Ketchum to return and battle her again though.
