Games
Lucy is one of the Frontier Brains and runs the Battle Pike in Battle Frontier. In order to battle her, players have to complete the Battle Pike at least two times without fail (meaning that you have to clear 27 consecutive rooms) in order to meet her. If you defeat her, you can get the Silver Luck Symbol. In order to challenge her for the Gold Symbol, you have to clear the Battle Pike another eight consecutive times, or 10 times in total, (for a grand total of 140 rooms).

Anime
Lucy is the Frontier Brain of the Battle Pike. Lucy is found to have a secret crush on Brock during an episode of Ash challenging her (episode 434, Queen of Serpentine), and often blushes when Brock faces her or says something to her. It is said she has a penchant for Pokémon with squinty eyes (such as Snorlax, Abra, Makuhita, Skitty, Swinub, and a Cyndaquil, all of which have squinty eyes), and since Brock has squinty eyes, she likes him a lot too.

Trivia

 * It was shown that she has some sort of interest to Brock because of his eyes.
 * Apparently, she is one of the only girls to show interest in Brock.
 * Her official art showed her to have pale skin, however in her sprites and in the anime she was seen with normal skin color.
