Tapu Koko then handed Kukui a Tapunium Z, and it and Kukui started performing . During this, Ash's Electrium Z once again transformed into a Pikashunium Z, allowing Pikachu to counter with 10,000,000 Volt Thunderbolt. The two Z-Moves clashed, with Pikachu's attack eventually overpowering Tapu Koko's, defeating it and making Ash the winner of the exhibition match.

Pikachu managed to bind Rotom with Electroweb, but just when he was about to use Thunderbolt on it, Volkner switched it out for Electivire, whose Motor Drive rendered Thunderbolt useless. After fighting against Electivire for a while, Pikachu was recalled and replaced with Lucario. Once both Ash and Volkner were down to their last Pokémon, Ash called Pikachu back to the battle to face Electivire again. Eventually, Ash decided to finish the match by using 10,000,000 Volt Thunderbolt. The Z-Move proved to be too much for Electivire's Motor Drive to absorb, leading to it being defeated and thus giving Ash the victory.
In The Sweet Taste of Battle!, Pikachu helped Ash during Opal's All-Alcremie Decoration Challenge. After Ash had won the contest, Opal challenged him to a battle, with Ash using Pikachu against Opal's . While Pikachu managed to land several Iron Tails on Alcremie, some of Alcremie's cream got stuck on Pikachu's tail, softening his blows. After Pikachu had managed to shake off Alcremie's and block her , Opal chose to Gigantamax her Pokémon and had it use , covering Pikachu in huge amounts of cream. Pikachu then started growing as well, becoming big enough to swallow an entire G-Max Finale cream projectile whole, much to Opal's shock. At first, everyone assumed that Pikachu had Gigantamaxed as well, but when Ash called for a G-Max Volt Crash and Pikachu didn't attack, it turned out that Pikachu had just eaten all the cream Alcremie had created with the G-Max Move and grown giant and fat as a result. As such, the battle was subsequently called off.
In Battle Three With Bea!, Pikachu was the first Pokémon used during his second rematch against Bea at the Stow-on-Side Stadium, first facing Grapploct. Pikachu's attempt at ensnaring Grapploct in an Electroweb proved unsuccessful, as it was able to use its stretchy tentacles to strike him through the web with a . As such, Ash chose to recall Pikachu. In the next episode, Pikachu was called back to the battlefield to face Bea's . By improving on a strategy he had used against both Lt. Surge and Visquez, Ash was able to repel Hawlucha's , while also dealing damage to it, allowing Pikachu to subsequently defeat it with a super effective Thunderbolt.

At the start of the next episode, Eternatus appeared above Wyndon Stadium and recharged Ash and Leon's Dynamax Bands, prompting Leon to temporarily recall Charizard and Gigantamax his Cinderace, with Ash doing the same with Pikachu. The two Pokémon's clash of G-Max Moves ended with both of them reverting to normal and Cinderace fainting, leaving Leon with just Charizard. During the subsequent battle between the two partner Pokémon, Pikachu took a severe hit from a and momentarily collapsed, experiencing a vision of all of Ash's Pokémon cheering for him.

In A Fated Face-Off!, Pikachu reunited with Misty and later acted as the referee for the match between her and Ash.

As Ash pondered over what it truly meant to be a Pokémon Master, Pikachu listened as Ash came to a personal conclusion about his journey. Deciding he had still yet to achieve his dream, Ash asked Pikachu if he would be there when he finally became a Pokémon Master, with Pikachu responding affirmatively. As such, they resolved to resume traveling, and Pikachu left Pallet Town with his Trainer once more.
===Personality and characteristics===
After Ash gained Pikachu's loyalty in Pokémon - I Choose You!, Pikachu became extremely loyal to Ash and has maintained this loyalty, and while he is not always immediately trusting of strangers, he is generally friendly to humans and Pokémon alike. He acted as a guardian and big brother to Misty's Togepi, and has been seen meditating and even breaking up fights among other Pokémon, such as in Pikachu's Vacation. In Mewtwo Strikes Back, Pikachu, , and Meowth's clone were the only Pokémon not to participate in the giant battle; Pikachu stood motionless as his clone repeatedly slapped his face. Contrary to his distrusting nature, Pikachu took a liking to Misty very early in the series, and he has retained this liking of Misty throughout the series, such as when he was very happy to see her in The Scheme Team, Alola, Kanto!, and A Fated Face-Off!. 
During the Hoenn saga, Pikachu temporarily developed amnesia and sided with for a while. On several occasions, Pikachu has developed an "electric flu" causing him to become overcharged and extremely powerful. During these instances, Pikachu will sometimes accidentally let off electric outbursts which can be set off on anyone, including Ash. In all of these cases, Pikachu did not mean harm upon anyone.
As shown in a handful of episodes, the first being Showdown at Dark City, Pikachu has a special fondness for ketchup, but he will eat and enjoy almost any other human or Pokémon food. In The Fires Of A Red-Hot Reunion, Pikachu also displayed a fondness for orange juice. In That's Some Spicy Island Research!, Pikachu was revealed to have a distaste for Poni Island radishes. A running joke in the series also seems to be Pikachu using Thunderbolt at the beginning of each series to accidentally destroy a female companion's bike or unintentionally shock the companion herself. This has happened to , , , , and .
Pikachu, like his Trainer, is always happy to battle. He often tries his very best, but when he loses, he doesn't complain or feel bad about himself, especially when Ash reassures him. Ash and Pikachu are almost identical personality-wise, and thus are the perfect match for one another. Most others agree, except for Burgundy, who in A Connoisseur's Revenge! said that Ash had a terrible relationship with all of his Pokémon, though this is more due to her inexperience in determining such relationships. Though rare, the two can still butt heads at times. When they first met, Pikachu would shock Ash with electricity out of vitriol. While being zapped by Pikachu still happens regularly for poor Ash, it's usually when he angers his buddy (such as when Ash rubs and pulls Pikachu's cheeks), or by accident (when Ash grabs Pikachu's tail by mistake).
In general, as a species are not particularly powerful, but Ash's Pikachu is a notable anomaly, overcoming odds in numerous times. In Ash Catches a Pokémon, remarked that Pikachu's power "exceeds its evolutionary level". In Showdown in Pewter City, he defeated Brock's Onix with an attack that triggered the sprinkler system causing Onix to be drenched in water, one of its weaknesses. Ash's Pikachu has also triumphed over some very powerful Pokémon that had previously defeated several of Ash's other Pokémon, such as 's , 's , and 's Mega . He was also the second Pokémon in the series to defeat a Legendary Pokémon in battle, defeating 's to win the Brave Symbol in Pace - The Final Frontier!. He later fought 's to a draw in the semifinals of the Lily of the Valley Conference, and defeated Gladion's Silvally and the commanded by in separate battles at Manalo Stadium. He has helped Ash win countless battles and Gym and matches.
The possibility of evolving into Raichu was first raised and discussed in the episode Electric Shock Showdown. After suffering a crushing defeat by Lt. Surge's Raichu, Nurse Joy presented Ash with a Thunder Stone. Ash allowed Pikachu to decide, but he refused, having decided to become stronger as he is, and defeated Raichu by using superior speed. In the Sinnoh region, Pikachu battled another Raichu belonging to a trainer named Sho. The two were not only even matches in power but, unlike before, also in speed; ultimately Raichu used to secure victory, a move Pikachu could not learn. At a Pokémon Center, Ash revealed that he kept the Thunder Stone he acquired in Vermilion City in case Pikachu changed his mind about evolving. Once again, Pikachu chose not to evolve and defeated Sho's Raichu in a rematch with a combination of speed, power, and spinning techniques learned from . During this event, stole the Thunder Stone, as they also wanted Pikachu to stay as he is.
However, at times, Pikachu has lived up to his species' frail and brittle strengths, particularly in Gym battles, where he was defeated with relative ease by his opponent; for example, he was overpowered very easily by Lt. Surge's Raichu, Sabrina's Kadabra, Blaine's Magmar, Bugsy's , Whitney's Miltank, Chuck's , Roark's Rampardos, Fantina's Drifblim, Cress's , and Viola's , despite having type advantages against Scyther, Poliwrath, Drifblim, Panpour, and Surskit. He also drew against Winona's and Norman's , and struggled against Crasher Wake's . Furthermore, he has lost twice to Trip's Serperior, as a Snivy in In the Shadow of Zekrom! and a Servine in A Rival Battle for Club Champ!, despite Trip being a starting Trainer and recently having obtained Serperior. In addition, Pikachu tends to noticeably struggle when an opponent hinders his mobility in some fashion, such as when the aforementioned Panpour stopped Volt Tackle with a that covered the battlefield, when Burgh's impared his speed and accuracy by immobilizing his tail with , when the icy battlefield of Viola's Surskit threw him off balance in the first battle, or when Wulfric's prevented him from using Quick Attack by numbing his legs with .
Pikachu is also the only one of Ash's Pokémon to accompany him to the Hoenn, Unova, Kalos, and Alola regions, and was intended to be the only Pokémon to accompany him to Sinnoh before was discovered to have stowed away on the ship Ash was taking. Up until the capture of Dawn's Pachirisu, Pikachu was the only Pokémon in the series owned by a main character.
Following their first encounter with him in Pokémon Emergency!, the Team Rocket trio made it their life's mission to capture Pikachu for their boss. Sometimes, they succeed with nets, cages, capsules, or one of their mechas, but most of the time their plans always failed by Ash and his friends or something else involved. Whenever Pikachu gets released from their trap and reunites with Ash, he sends Team Rocket blasting off with his attacks. Most of the time, in this case, his Thunderbolt. Sometimes, Pikachu sends them away even when he didn't get stolen. On other occasions, he battles them with Ash.
Even with his high level of electrical power, Pikachu has not stopped learning new attacks. Upon learning that Roxanne, the Rustboro Gym Leader used Rock types, Ash had Pikachu begin learning Iron Tail in All Things Bright and Beautifly!. After training hard, Pikachu finally perfected it in The Winner by a Nosepass, where he used it to defeat Roxanne's and earn Ash his first Hoenn Badge. In addition to giving Pikachu an advantage over Rock types, Iron Tail has allowed Pikachu to defeat many other powerful opponents. In May's Egg-Cellent Adventure, during a battle with Team Rocket, Ash ordered Pikachu to do a Quick Attack. Much to the surprise of Ash and his friends, the Quick Attack morphed into an imperfect which sent Team Rocket blasting off. Upon mastering the move in The Green Guardian, it became one of Pikachu's most distinctive techniques, to the point of garnering Paul's interest, up until Dancing With the Ducklett Trio!, where Pikachu replaced it with Electro Ball. In A Battle Hand-Off!, Pikachu learned in place of Electro Ball, allowing him to not only trap opponents, but also use the move as a springboard to increase his mobility or as a shield to protect himself from damage. In addition to his repertoire of moves, Pikachu has used his Ability, , a few times in the series, has an affinity for Z-Moves, and is capable of Gigantamaxing.
Although he is always ready for a battle and presumes that his Trainer will choose him, Pikachu can get annoyed and disappointed if Ash chooses a different Pokémon, like in Battling Besties or Thrash of the Titans, but he always agrees with Ash's decision in the end. Pikachu's dislike for going into his and Ash's respect for it extend even into situations where doing so would have been a beneficial choice, such as in Showdown at the Gates of Warp!, where Ash simply put his partner in his pocket instead of recalling him to protect him from the effect of a time reversal that had caused him to devolve.
====Pikachu's imitations====
Pikachu has demonstrated a great talent for mimicking Pokémon, altering the look of his physical features to match another Pokémon's appearance. He will occasionally use this talent to specify what Pokémon or person he is talking about. These imitation skills were notably put to use during the Pokémon Dress-Up Contest, where Pikachu was able to thrill the audience without the need for a costume or make-up.

====Pikachu's language====
Some of Pikachu's speech is consistent enough that it seems that some phrases mean something. In Stealing The Conversation!, refers to this language as "Pika-speak," but this most likely isn't official. This includes:

* PiPi-kachu: Rocket-dan (Team Rocket)
* Pi-Pikachu: Get da ze! (He says this after Ash wins a Badge, catches a new Pokémon or anything similar.)
** Pikachu may not be the only one to use this phrase, as other Pokémon do this as well. For example, when Iris caught Emolga, Axew said Ax-Axew (Ki-Kibago in the Japanese version). This also happened when Iris caught in BWS02.
* Pika-Pikachu: When referring to or introducing himself.
* Chaa: Anything he says happily or excitedly, or when yawning.
* Pika!: "Matte!", or saying "Wait!"
* Pi-kaPika: "Sayōnara," or saying "Good-bye."
