Pikachu's debut appearance
In the first episode of the Pokémon anime, Pokémon - I Choose You!, Ash woke up late the day he was supposed to go to Professor Oak's Laboratory to obtain his first Pokémon. When he arrived at the lab, the three available starter Pokémon, Bulbasaur, Charmander, and Squirtle, had already been taken by other Trainers who had arrived on time. Seeing Ash's disappointment, Professor Oak gave him Pikachu, who, at first, did not care at all for his new Trainer, constantly zapping him and anyone else nearby. He refused to go into his Poké Ball, and when Ash failed to catch a Pidgey, he laughed at him. However, by the end of the episode, Ash gained Pikachu's trust by protecting him from an attack by a flock of angry Spearow. Seeing this act of selflessness, Pikachu defended Ash from the Spearow as well, and the two of them became inseparable friends, a moment that was capitalized on by catching a glimpse of an unknown Pokémon flying by. Ash then rushed to Viridian City to get Pikachu hospitalized quickly, as he had been badly injured during the fight.
Pikachu and Ash meeting for the first time
In Pokémon Emergency!, Ash managed to get to the Viridian City Pokémon Center just in time with the help of Officer Jenny, who scolded Ash for "mistreating" Pikachu. Nurse Joy agreed to heal Pikachu, and thanks to her, Pikachu managed to regain his health. At the end of the episode, Pikachu had regained enough of his strength to send Team Rocket blasting off for the very first time.
Pikachu participated in Ash's first Gym battle with Brock in Showdown in Pewter City. He faced Onix, but his Electric-type attacks were ineffective. Onix then started binding Pikachu. Seeing no other option, Ash forfeited. Ash and Pikachu later trained with Flint to increase the strength of Pikachu's Electric-type moves. Ash later challenged Brock to a rematch, where Pikachu managed to defeat Brock's Geodude with his training. Pikachu then faced Onix again, but despite their training, he was still unable to defeat it. As Ash was about to forfeit again, Pikachu's Thunderbolt managed to turn on the Gym's sprinkler system, severely harming Onix. As Ash was about to let Pikachu finish Onix off, he was stopped by Brock's siblings and he decided to forfeit again. Despite this, Brock still gave him the Boulder Badge.
Ash rushing Pikachu to the Pokémon Center
Pikachu's next major battle was in Ash's Vermilion Gym battle against Lt. Surge's Raichu in Electric Shock Showdown. Lt. Surge laughed at Ash for attempting to defeat his Raichu with its pre-evolved form, angering Ash and Pikachu. Indeed, Raichu turned out to be more powerful than Pikachu, and a combination of attacks from it resulted in so much damage to Pikachu that he had to be hospitalized. Later, Ash offered to let Pikachu evolve into a Raichu with a Thunder Stone that Nurse Joy had given him. However, Pikachu refused, wanting to defeat Raichu on his own terms. During the subsequent rematch with Lt. Surge, Pikachu once again faced Raichu. Using moves like Agility and Quick Attack, which Raichu didn't know, Pikachu managed to gain the upper hand, dodge Raichu's attacks, and ultimately defeat it, thus earning Ash the Thunder Badge.
In Abra and the Psychic Showdown, Pikachu was sent out to battle Sabrina's Abra during Ash's Saffron Gym battle. It proved to be a tough foe, using Teleport to avoid Pikachu's attacks. Abra then suddenly evolved into Kadabra, making it much stronger. Eventually, Kadabra used Psychic to control Pikachu's body and repeatedly smash him into the ceiling. Unwilling to see his friend suffer, Ash forfeited the match. In Ash's subsequent rematch with Sabrina in Haunter versus Kadabra, Pikachu fought Kadabra again, since Haunter didn't show up and his other Pokémon were too terrified. Eventually, Haunter appeared and made Sabrina and Kadabra laugh, leaving them incapacitated. As a result, Ash was declared the winner by Sabrina's father, which earned him the Marsh Badge.
In The Flame Pokémon-athon!, Pikachu entered the Big P Pokémon Race with Squirtle. The two were at a significant disadvantage due to Squirtle's short legs, and Pikachu's comparative weight, but in a way, this helped as they managed to escape an Electrode self-destructing.

However, intervention from Team Rocket forced a battle, and the two were put out of the running by a Glare attack from Arbok.
In Pikachu's Goodbye, Ash and his friends ran into a group of wild Pikachu, which was a very rare encounter. Pikachu tried to make friends with the other Pikachu but received a lukewarm response.

Ash was overjoyed by this at first but soon began to feel sad, because he thought that Pikachu would be better off with the rest of his kind. After stopping Team Rocket from poaching his Pikachu and the wild Pikachu, Ash decided it was best to leave Pikachu behind with the others. However, Pikachu refused to leave Ash and quickly ran to catch up with him, followed by the wild Pikachu, who supported Ash and Pikachu being together.

The real Scyther then appeared behind Pikachu and hit him with a series of Fury Cutter, knocking him out.
In A Goldenrod Opportunity, Pikachu faced off against Whitney's powerful Miltank, who had already easily defeated Ash's Cyndaquil and Totodile using Rollout. Ash had Pikachu use Thunderbolt on Miltank since she got wet by Totodile's earlier Water Gun. However, due to Miltank spinning at great speed, she had already dried up, making Thunderbolt useless. Afterwards, Pikachu was defeated by two Rollout attacks, causing Ash to lose the battle. In the following episode, Pikachu battled Miltank again in Ash's rematch.

In SM142, Ash chose to use Pikachu to battle Professor Kukui's Empoleon during Ash's exhibition match against him. While the two Pokémon were equally matched, Pikachu was eventually caught in Empoleon's Whirlpool, causing him to get dizzy. To save Pikachu from being defeated, Ash withdrew him from the battle and sent out Melmetal to replace him.
In SM144, Ash sent Pikachu back into the battle as his final Pokémon to face Tapu Koko, who had taken the place of Kukui's sixth Pokémon in the match. When both Pokémon were evenly matched, Tapu Koko and its fellow deities restored Ash and Kukui's Z-Power, giving them a chance to use another Z-Move, since they already used up their Z-Moves for the match. Tapu Koko then handed Kukui a Tapunium Z, and it and Kukui started performing Guardian of Alola. 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.
In SM146, Pikachu said farewell to his Alola friends as he and Ash returned to Pallet Town to continue their journey.
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, Meowth, 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 and Alola, Kanto!.
Pikachu and his love of ketchup
During the Hoenn saga, Pikachu temporarily developed amnesia and sided with Team Rocket 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 shown to have a distaste for Poni Island radishes. A running joke in the anime 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 Misty, May, Dawn, Iris, and Bonnie.
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.
Pikachu does not like having his cheeks rubbed
In general, Pikachu as a species is not particularly powerful, but Ash's Pikachu is an anomaly, overcoming odds in battle numerous times. In Pokémon Emergency!, Meowth remarked that Pikachu's power "far exceeds its evolutionary level". In Showdown in Pewter City, he defeated Brock's Onix with an Electric-type attack that triggered the sprinkler system causing Onix to be drenched in water, one of its weaknesses. Ash's Pikachu has also defeated very powerful Pokémon that Ash's other Pokémon were unable to, such as Dragonite, Metagross and Mega Lucario. He was also the second of Ash's Pokémon to defeat a legendary Pokémon in battle, defeating Brandon's Regice to win the Brave Symbol. He later fought Tobias's Latios to a draw in the semi-finals of the Lily of the Valley Conference. He also defeated Gladion's Silvally in SM138 of the Manalo Conference. He has helped Ash win countless battles and Gym and League matches.
The possibility of evolving into Raichu was first raised 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 it smacked the stone away with his tail, choosing to become stronger as it is, and defeated Raichu using its superior speed. In the Sinnoh region, Pikachu battled a Raichu belonging to a trainer named Sho. The two were evenly matched until Raichu used Hyper Beam 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 and spinning techniques learned from Dawn. In the interim, Team Rocket stole the Thunder Stone, as they also liked Pikachu to stay as he is. After those events, Ash respects Pikachu's wishes to stay the way he is, shown in Climbing the Tower of Success! when he prevented his evolution when a Thunder Stone that was accidentally thrown to him during a contest they were entering. When Bonnie and Ash's classmates ask if he was gonna evolve, shown in The Cave of Trials! and Turning Heads and Training Hard!, Ash simply answer them that Pikachu doesn't really want to evolve and they made their choice.
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 Scyther, Whitney's Miltank, Chuck's Poliwrath, Roark's Rampardos, Fantina's Drifblim, Cress's Panpour, and Viola's Surskit, despite having a type advantage with Scyther, Poliwrath, Drifblim, Panpour, and Surskit. He also drew against Winona's Pelipper and Norman's Vigoroth, and struggled against Crasher Wake's Floatzel. 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 struggle when his mobility is hindered, such as when the aforementioned Panpour weakened Volt Tackle with Mud Sport, when the icy battlefield of Viola's Surskit threw him off balance in the first battle, or when his legs were numbed by Wulfric's Bergmite and its Icy Wind, preventing him from using Quick Attack.
Pikachu became the second non-legendary Pokémon to defeat a legendary Pokémon in the anime after Charizard. It was able to beat Brandon's Regice in Pace - The Final Frontier!, giving Ash his final Frontier Symbol.
Pikachu walking along Dawn's Piplup
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 Aipom was discovered to have stowed away on the ship Ash was taking. Up until the capture of Dawn's Pachirisu, Pikachu was the only Electric-type Pokémon in the anime owned by a main character.
Pikachu is always becoming a constant target whenever he gets captured by Team Rocket. Sometimes, they succeed with nets, cages, capsules or different devices, but most of the time their plans always failed by Ash and his friends or something else. Whenever Pikachu gets released from their trap and reunites with Ash, he sends Team Rocket blasting off with his Electric 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 Nosepass 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 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 Volt Tackle which sent Team Rocket blasting off. Until Dancing With the Ducklett Trio!, it has been one of Pikachu's signature moves, in which Pikachu replaced it with Electro Ball, which it learned while battling a trio of annoying Ducklett. Not only that, Pikachu has used his Ability, Static, a few times in the anime.
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.
Some of Pikachu's speech is consistent enough that it seems that some phrases mean something. (In Stealing The Conversation!, Team Rocket refers to this language as "PikaSpeak," but this most likely isn't official.) For instance, Pikachu always uses "Pikapi" when referring to Ash (notice that it sounds somewhat similar to "Satoshi"). Other speech includes:
- Pi-Kachu: Pochama (Piplup)
- Pikachu-Pi: Kasumi (Misty)
- Pika-Chu: Takeshi (Brock), Kibago (Axew)
- Pikaka: Hikari (Dawn)
- PiPiPi: Togepy (Togepi)
- PikakaPika: Fushigidane (Bulbasaur)
- PikaPika: Zenigame (Squirtle), Mukuhawk (Staraptor), Goukazaru (Infernape) Gamagaru (Palpitoad) or Marilli (Azumarill)
- 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). This also happened when Iris caught Gible 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."
