Mischievous Lacey (Japanese: ワルい子のタロ!? Bad Girl Taro!?) was a story event in Pokémon Masters EX. It was focused on the sync pair Lacey (Fall 2025) & Whimsicott.

The "Lacey Seasonal Scout" gave players an increased chance of recruiting Lacey (Fall 2025) & Whimsicott for the duration of the event.

During this event, players could earn event points by completing battles. Players received rewards based on the number of points accumulated, including 5★ Scout Tickets, a Support Move Candy Coin, a 5★ Power-Up, and medals. All battles could be challenged an unlimited number of times except Daily Extreme Battle 1, which could only be challenged once per day.

The player could battle using Lacey (Fall 2025) & Whimsicott to obtain +0.6× bonus points; Bellelba & Swoobat, Iono (Fall 2024) & Flutter Mane, Shauntal (Fall 2024) & Froslass, Roxanne (Fall 2023) & Runerigus, Phoebe (Fall 2023) & Cofagrigus, Iris (Fall 2022) & Naganadel, Allister (Fall 2022) & Gourgeist, Caitlin (Fall 2021) & Sableye, Morty (Fall 2021) & Banette, Acerola (Fall 2020) & Mimikyu, or Hilbert (Fall 2020) & Mightyena to obtain +0.4× bonus points; and any unlisted Paldea sync pairs to obtain +0.2× bonus points.

This event featured the Battle Challenge, where players were challenged to defeat a team of strong opponents. Players could complete event missions by clearing these areas with one or fewer sync pairs fainting and sync pairs with specific theme skills on the team.

For the duration of the event, a splash screen featuring art of Lacey (Fall 2025) & Whimsicott was displayed when opening the game.

Plot

At Pasio Academy, the player runs into Ilima and Lacey, who seem troubled. Lacey asks the player if they know any events that anyone can join, explaining that she has been assigned to a committee that'll be hosting an academy event, but is stumped on ideas. The player suggests the Midnight Parade, so Lacey decides to join the event this year to search for inspiration.

Arriving at the Midnight Parade with her Whimsicott alongside the player, Lacey observes that Ghost-type Pokémon seem to be the main focus and that many Trainers seem have gone for "spooky cute" costumes. The pair encounters Sabrina, who had a premonition that she should participate as well. Seeing as neither of them are wearing costumes, Lacey proposes that Sabrina check out the event with them. They soon encounter Hilbert, Iris and Shauntal who challenge them to fight or fright.

The three wander to the Midnight Ball, a social event hosted by Darach, Ingo, and Emmet. Lacey explains to the hosts that she is event planning for Pasio Academy. Caitlin notes that she won't be able to fully enjoy the Midnight Parade if she's busy planning, but Lacey shrugs this off. While Lacey seeks out more advice from the butlers about hospitality, Sabrina departs for a moment before returning as Bellelba, much to Lacey's amazement.

Bellelba orders Lacey and the player to guide her around the Midnight Parade. The three run into Cilan, Chili, and Cress at a restaraunt, who feign fright and play along with Bellelba's threats despite Lacey's concern. Later, Lacey expresses alarm when Bellelba threatens to steal candy from a group of children, and becomes confused that everyone is still happy despite her being selfish and mean. Bellelba explains that this is the one day when evildoers are more popular than heroes, and she suggests Lacey should loosen up for some evil, harmless fun. Though Lacey struggles with the idea, seeing her Whimiscott being receptive to it gives her pause.

Some time later, Lacey returns in her fall outfit, having decided to embrace a bit of devious fun for everyone. She starts by supporting Bellelba and the player during a Pokémon battle against the Striaton City Gym Leaders, and when the group challenges another group of kids to fight or fright, she reveals that she even had Whimiscott's Tera Type changed to Dark. Days after the Midnight Parade ends, Lacey is relieved when the committee approves her event idea, who called its dark twist unlike her in a good way. Thanking Sabrina for encouraging her to enjoy the Midnight Parade, she realizes that she missed out on noticing Sabrina being just as cute the whole time. Flustered, Sabrina jokes that perhaps Lacey is bad after all.
