History

Past

One year prior to the Sword & Shield arc, Casey and Henry first met at the entrance of the Slumbering Weald. Despite it being forbidden to enter, they went inside to obtain a Wishing Star Casey spotted falling into the forest. They found two Wishing Stars, with Casey taking one for herself and giving the other to Henry as thanks for his help. Casey and Henry then found themselves surrounded by the Legendary Pokémon Zacian and Zamazenta. Realizing the two Pokémon were merely illusions, Casey and Henry passed through them, only to be knocked unconscious by a bright flash of light. After coming to, Casey was distraught to find that her Pokémon had gone missing. After a failed search attempt, Casey and Henry decided the only way to find Casey's missing team members was to enter the Gym Challenge, hoping to use their fame to spread the word about the missing Pokémon.

Sword & Shield arc

Casey debuted in Wow!! That's One Big Pokémon. She was first seen meeting a young boy named Marvin. She took the boy to meet Henry, who had saved his life earlier that day. After a brief introduction, Casey offered to let Marvin participate in a Dynamax simulation with her and Henry. Together, they fought and defeated a Dynamax Pangoro hologram, giving Marvin the confidence to set out on a Pokémon journey. Having received approval from his parents, Marvin joined the others on their quest to study Dynamax. Later, everyone found Leon on the outskirts of Wedgehurst, trying to move a large flock of Wooloo off of some train tracks. Casey and Henry stepped in to help, driving off an Obstagoon that was terrorizing the Wooloo. After introducing themselves, Leon left to appear on a television program in Motostoke. To Marvin's surprise, Casey and Henry revealed they helped Leon hoping that their efforts would leave enough of an impression that he'd give them an endorsement for the Gym Challenge.

In Chomp!! Defeat Drednaw, the trailer house was attacked by a trio of wild Drednaw. In order to battle the Bite Pokémon, Casey and Henry each received a Rotom Phone with a Pokédex function installed, officially making them both Pokédex holders. With some assistance from Sobble, the Drednaw were defeated. Afterward, Professor Magnolia suggested Marvin keep Sobble, which he happily accepted.

In Zap!! A Rising Beam of Light, Casey and the others arrived in the Wild Area. While they traveled, Casey was delivered a package that contained Gym Challenge uniforms for her and Henry. When a pair of Team Yell Grunts tried to destroy the uniforms, Casey and Henry pushed them into a Pokémon Den, forcing the four to team up in a Max Raid Battle against the wild Gurdurr that lurked inside. Eventually, the Gurdurr was defeated and caught by Henry, but the Grunts' Pokémon were knocked out during the battle, forcing them to flee.

In Watch Out!! Strong Rivals, Casey and Henry registered for the Gym Challenge in Motostoke. The group encountered Sonia, a researcher and Magnolia's granddaughter. When the trailer car broke down, Magnolia asked the others to research the geoglyph in Turffield in her place. Along the way, on Route 3, Casey and the others met Hop, Bede, and Marnie, a trio of Gym Challengers. They were unable to progress due to a large boulder blocking the entrance to Galar Mine. By combining their Pokémon's attacks, Casey and the others moved the boulder and went ahead. Later, everyone gathered at Turffield Stadium, where they watched Henry face Milo in a Gym battle and won. Once Casey won her match, she, Henry, and Marvin prepared to head off to the next Gym in Hulbury.

In Splish Splash!! Gigantamax Battle, Casey faced Nessa in a Gym battle. She won due to Scorbunny evolving into Raboot as well as Nessa's Pokémon still being tired from their earlier battle with Henry. Realizing that she won't last much longer in the Gym Challenge with only a single Pokémon, Casey cried out, begging for her missing team members to return.

In Blazing!! Bede's Feelings, Casey used an interview to inform the public about her missing team members. Sometime afterward, she was approached by Hop, who had spotted an Arrokuda in a nearby swamp. Hoping it was Kilo, Casey grabbed Hop and ran off to search for it. At the swamp, they successfully located Kilo, only to find it being eaten by a wild Cramorant. By combining their efforts, Kilo was freed from Cramorant's stomach and rejoined its Trainer. Once they went their separate ways, Casey challenged the Motostoke Gym Leader Kabu and won.

In PASS13, she and the others met Raihan, the Hammerlocke Gym Leader, and Opal, the Ballonlea Gym Leader. Opal briefly traveled with them to Stow-on-Side before returning home. Casey then watched Henry's Gym battle with Allister. After Henry's victory, Casey, Allister, Marvin, and Professor Magnolia went to investigate a loud sound coming from the Stow-on-Side mural. There, they found Bede trying to destroy the mural in an unsuccessful attempt to obtain Wishing Stars. Bede ignored Allister's pleas to stop, claiming his actions were a mission from Rose himself. Before he could continue, Bede was captured by several League Staff members and approached by Rose, who disqualified him from the Gym Challenge as punishment for damaging a historic landmark.

In PASS15, Casey and the others found Allister stowed away in the trailer house. Upon learning Professor Magnolia found her Antique Form Sinistea and Polteageist at Glimwood Tangle, Allister immediately left to find some for himself. Casey followed Allister into the forest, where they found an injured Dreepy whose caretaker, Drakloak, was fighting Tera. With Casey's quick thinking, Tera won the battle and rejoined its Trainer's team.

Casey battling Opal

In PASS18, Casey faced Opal in a Gym battle. Despite learning that Tera was capable of Gigantamaxing, it was defeated by Opal's Gigantamax Alcremie, eliminating Casey from the Gym Challenge. Henry promised to help keep the public informed of Casey's missing team members. They traveled to Route 9 Tunnel, where people had reported seeing Pokémon Dynamaxing despite it not being a Power Spot. They found several Trainers attacking a wild Dracovish, but Marvin saved it by catching Dracovish and escaping with the others. Upon arriving at Circhester, the group encountered the Gym Leader Melony, who requested that Henry repair an ice cane tool belonging to her Mr. Rime. A group of Eiscue stole the cane and Mr. Rime's Poké Ball. The Ice-type Pokémon in the area were fans of Mr. Rime, who used to put on performances for them. Casey reunited with Peta, who helped keep the other Pokémon at bay while Henry finished the repairs.

Afterward, Sonia took everyone to the Bob's Your Uncle restaurant, where a tapestry originally from the Hammerlocke vault was being held. She speculated it was thrown away to keep a piece of Galar's history out of public knowledge. Upon examining the tapestries, Casey regained some memories of the Slumbering Weald incident. She told Henry the culprits who stole her Pokémon and the Rusted Sword and Shield were a couple of celebrities.

In PASS22, Sonia told Casey and the others to meet her around Spikemuth so she could deliver information on the thieves behind the Slumbering Weald incident. While they waited, the trailer car was attacked by a Golisopod and Bronzong belonging to Sordward and Shielbert, whom Casey recognized as the thieves from a year ago. The brothers agreed to return Mega and Giga if Casey handed over a camera to them, only for Piers to appear and reveal the camera was in his possession. Piers gave the camera up and convinced the brothers to leave, only to have secretly removed the memory card containing the incriminating data. When the brothers returned for the memory card, Casey and the others uncovered their faces. Sordward and Shielbert attacked Casey and Henry, but were easily defeated by Piers and forced to flee. Casey and the others reunited with Marnie and Hop, the former revealing she and Piers are siblings.

In PASS25, after being informed by Leon and Sonia that Rose, Sordward, and Shielbert were working together, Casey's group and the Gym Leaders gathered at Rose Tower to find out if Rose intended on bringing harm to Galar. While the Gym Leaders were impeded by Oleana, Casey, Henry, Bede, Hop, and Marnie went to meet with Rose, only to find he was actually in Hammerlocke. On a video screen, Rose appeared and revealed his plan to restart the Darkest Day and ensure the safety of Galar's future. Power Spot lights began appearing all over the region, causing Pokémon to start Dynamaxing at random. While heading to Hammerlocke, Casey's group watched a news program where Sordward and Shielbert announced their intention to use the Rusted Sword and Shield to take out Eternatus, the Pokémon causing the Darkest Day. Upon arriving at the Energy Plant, everyone ran into Leon's group and found Rose ecstatic that his plan was a success.
