As a wild Pokémon
Mimikyu first appeared in Loading the Dex!, where it met Team Rocket in a forest on Melemele Island. Thinking it was cute, Jessie decided to catch Mimikyu. Having no offensive Pokémon yet, she threw Meowth at Mimikyu, but it was immune to Meowth's Fury Swipes. Losing his patience, Meowth tried to remove Mimikyu's rag, but was hexed, and had a near-death experience. Jessie and James were able to wake Meowth up, but were forced to give up and hide when they heard someone approach, who turned out to be Ash and his classmates. Having noticed Ash's Pikachu, Mimikyu became enraged. Ash attempted to catch Mimikyu, but Pikachu's Iron Tail had no effect due to Mimikyu's Ability Disguise. Mimikyu then beat up Pikachu using Play Rough. Before the battle between Pikachu and Mimikyu went too far, Team Rocket stepped in. Meowth jumped at Pikachu with Fury Swipes, but when Pikachu tried to counter, Mimikyu intervened. Speaking through Meowth, Mimikyu told Team Rocket that it would help them against Pikachu, expressing a deep-seated hatred for it. Before it could resume fighting Pikachu, however, a Bewear kidnapped Jessie and James. Meowth was able to get Mimikyu to disengage, and they chased Bewear.
In First Catch in Alola, Ketchum-Style!, Team Rocket and Mimikyu were trapped in Bewear's den. Jessie was attempting to catch Mimikyu with a Poké Ball, because neither Meowth nor Wobbuffet could beat Bewear, but Mimikyu kept swatting it away with its tail stick. At some point, James dropped a Luxury Ball he was going to add to his collection. Jessie threw it at Mimikyu and successfully caught it. During their first battle with Pikachu, Mimikyu was called out and used Shadow Ball, but Pikachu used Electro Ball to intercept. Mimikyu used Play Rough on him and was about to use Shadow Claw, but thanks to Rowlet's Leafage, Pikachu was saved. Before the fight lasted too long, Bewear returned and carried Team Rocket away.
In A Team-on-Team Tussle!, Mimikyu assisted Team Rocket in their quest to obtain a Darkinium Z. It battled a Totem Alolan Raticate which protected the Z-Crystal, but was swatted away by Raticate's tail. When Raticate was about to finish Team Rocket and some Team Skull Grunts off, Mimikyu emerged from the bushes and managed to defeat Raticate with a powerful combination of Wood Hammer and a super effective Play Rough.
In Mimikyu Unmasked!, Jessie sent Mimikyu out to battle Ash during another attempt to steal Pikachu. Team Rocket was quickly blasted off by Kiawe's Turtonator's Inferno Overdrive, separating Mimikyu and its Trainer from James, Meowth, and Wobbuffet. The Z-Move had also ripped Mimikyu's rag, forcing it to wear a malasada bag instead. Jessie and Mimikyu went shopping to find a replacement for Mimikyu's rag, but the Disguise Pokémon became irritated by Jessie's different outfits and stormed out of the store. Jessie was then able to convince Mimikyu to hand over its rag, allowing her to repair it. When Jessie later opened her bag of malasadas, a trio of Murkrow stole them, but also accidentally took Mimikyu's rag. Jessie, however, was able to retrieve it. When a larger flock of Murkrow returned for an attack, Mimikyu slid into its repaired rag and protected its Trainer from the flock. Later, Team Rocket returned to Ash for a rematch. Despite Mimikyu and Jessie's improved relationship, Mimikyu still ignored her commands to attack Lycanroc and attacked Pikachu instead, leaving Team Rocket open to Lycanroc's Continental Crush, sending them flying until Bewear arrived to take them to its den.
Mimikyu was used in A Battle Hand-Off! at the Thrifty Megamart, where it battled Ash's Pikachu during Ash's Ula'ula Island trial. During the battle, it quickly gained the upper hand by overwhelming Pikachu with its fast and powerful attacks. At one point, Bewear arrived to take Team Rocket home, but Mimikyu managed to get Bewear to hold off and the battle continued. Eventually, Mimikyu prepared to finish off an exhausted Pikachu by using Let's Snuggle Forever for the first time. However, Pikachu was able to survive the Z-Move when it shielded itself with its newly learned move Electroweb. When Ash's Electrium Z turned into a Pikashunium Z, Pikachu was able to use 10,000,000 Volt Thunderbolt, which defeated Mimikyu.
In Securing the Future!, Mimikyu joined the rest of Alola in showering Necrozma with light so it could return to its normal form.
In SM129, Jessie used Mimikyu in the Battle Royal round of the Manalo Conference. However, it refused to follow her instructions and attacked any Pikachu it saw. It subsequently defeated Pikala's Pikachu, Bolt, and entered a heated battle with Ash's Pikachu, which nearly gave Jessie's identity away. Jessie managed to recall Mimikyu when it tried to continue fighting Ash's Pikachu even after the round ended, narrowly allowing Jessie to advance to the Top 16.
Personality and characteristics
Unlike most Mimikyu who cosplay as Pikachu so that they can make friends like Pikachu, Jessie's Mimikyu bears an intense grudge towards all Pikachu and only dresses up like one because it is the thing that it despises the most. As a wild Pokémon, Mimikyu agreed to fight alongside Team Rocket so it could fight Ash's Pikachu. As seen in A Shocking Grocery Run!, it even fights Pikachu when its Trainer told it not to, because of its intense hatred towards him. Every time it sees Pikachu, it always engages in battle, which is helpful for Team Rocket, as it is their lifelong goal to capture Pikachu. However, this has not always worked out in Team Rocket's favor, as shown in Racing to a Big Event!, when Mimikyu tried to attack Pikachu during the Pokémon Pancake Race, thus disqualifying itself due to the race's rules, much to Jessie's chagrin. This was also shown in Acting True to Form! when Mimikyu attacked the cage that Pikachu was trapped in with Shadow Claw and that attack ended up allowing Pikachu to get out. Mimikyu's desire to only battle Pikachu leads to problems, as seen in SM129, where it ignored Jessie's commands to keep a low profile during the Battle Royal round of the Manalo Conference, and chose to attack the competing Pikachu. Even when Jessie recalled Mimikyu to its Luxury Ball, Mimikyu was still attempting to attack.
As demonstrated in Getting to Know You!, Mimikyu will also often refuse to fight any opponents that are not Pikachu, further displaying its obsession, but it did willingly attack DJ Leo's Dugtrio in Getting the Band Back Together! and a Totem Alolan Raticate in A Team-on-Team Tussle!. It did also attack Ash's Rowlet in The Sun, the Scare, the Secret Lair!, although it could have done so due to it disrupting its own battle with Pikachu. In Show Me the Metal!, Jessie ordered Mimikyu to use Shadow Ball on a group of Meltan, its lack of interest in battling anything other than Pikachu resulted in it firing a small Shadow Ball which didn't go far. Mimikyu will not always do as its Trainer commands. It spends a lot of its time outside of its Poké Ball, wandering around and generally doing as it likes, including going for a swim, as seen in The Sun, the Scare, the Secret Lair!. Although it did not have a strong relationship with Jessie at first, its bond with its Trainer grew in Mimikyu Unmasked! when Jessie repaired its torn disguise and Mimikyu protected her from a flock of Murkrow. Since then, its relationship has continued to grow as shown in Getting a Jump on the Competition!, when it competed alongside Jessie in the Pokémon Sled Jump Games and put on a performance with no attempt to disobey its Trainer.
Mimikyu's speech, according to Meowth, is very intimidating. When Team Rocket first met it, both he and the normally chipper Wobbuffet were deeply disturbed by Mimikyu's words. Since its debut, it is often seen scaring Meowth. In the Poké Problem for Mimikyu Unmasked!, Mimikyu has its disguise washed and dried on a clothes line.
Mimikyu appears to enjoy causing trouble for Meowth by showing him its true form. This was seen in Mimikyu Unmasked!, where it intentionally left Meowth unprotected, whereas Jessie and James received its protection.

|Description: Mimikyu strikes a series of synchronized poses with its Trainer to build Z-Power. It then jumps towards it opponent, expands the size of its disguise and then lands over the opponent, covering them. While inside its rag, Mimikyu attacks the opponent.
In A Plethora of Pikachu!, Jessie revealed a variation she named (Japanese: 全力キープ Full-Force Keep). If she doesn't finish the pose for Let's Snuggle Forever, Mimikyu will not begin attacking. If it stays in this state for long enough, the hot air produced inside its rags will allow Mimikyu to float. Team Rocket used this discovery to steal as many Pikachu from the Pikachu Valley inside its rags, but Mimikyu was stopped by Pikala and the Boss.
