an ext than simply being the series" mascot, Ash"s Pikachu in Pokémon has actually been his journey-long companion due to the fact that Episode 1 that the anime, v hardly any kind of episodes without him. But one rapid look at the games" stats will tell friend that Pikachu is not a particularly strong Pokémon with typical abilities that almost twin upon evolving to Raichu -- therefore why hasn"t he? with over 20 years" precious of episodes and multiple Thunderstones available, why hasn"t Ash advanced Pikachu to his stronger, more impressive and final form?
The answer"s simple: in Ash"s mind, it was never his an option to make -- it was Pikachu"s. As a human who never ever evolves, Ash doesn"t have actually a structure of reference for what development is like, other than outward observation. Together such, transparent the series, he"s never trained a Pokémon through the intent of forcing it to evolve, nor has actually he concentrated on development as a method of growing much more powerful. If he"s always happy because that his Pokémon once they carry out evolve, he"s additionally always respected your own options to stay the same, together as as soon as Bulbasaur made decision not to evolve in Season 1, episode 48, "Bulbasaur"s secret Garden."
for this reason why doesn"t Pikachu desire to evolve? He"s always on Ash"s side, and growing stronger for his trainer"s benefits is miscellaneous he"s done time and time again, even if it is it it is in learning brand-new moves prefer Iron Tail or Volt Tackle, or taking component in Ash"s unorthodox training methods wholeheartedly. The very first time Pikachu was faced with this an option was in Season 1, illustration 14, "Electric Shock Showdown," wherein after being soundly pounded by Lt. Surge"s Raichu, a well-meaning Nurse Joy provides Ash a Thunderstone, and also both advises and warns him around evolution being irreversible.

It doesn"t take lengthy for Ash, who by this point had only had actually one Pokémon evolve (his Butterfree) to offer the choice to Pikachu. The are afraid of change is apparent in his eyes -- and also when Pikachu skillful swats the evolutionary stone out that Ash"s hand, the two solve to grow stronger as they space -- together. Through taking advantage of Lt. Surge"s Raichu"s rapid evolution, castle two space able to prove your mettle and also defeat Surge for Ash"s first truly earned badge.
But that"s no the finish of the story -- it"s revealed in Season 11, illustration 20, "Pika and also Goliath" that Ash kept the Thunderstone, just in instance Pikachu should readjust his mind around the totality "evolution" thing. This has actually its own sweetness, as it mirrors Ash is considering Pikachu"s feeling not only in the present, however in the future, and is ready to allow Pikachu to evolve at any type of time -- noted that"s what Pikachu wants.
once Pikachu is yet again bested by a Raichu, Ash gift the choice to Pikachu once more -- this time with the caveat that this Raichu knows Hyper Beam, which Pikachu can"t discover unless the evolves. At first, Pikachu reflects disdain because that the Thunder stone but later on looks at it an ext seriously, prior to the present cuts far to Ash return to Pikachu"s bedside -- to uncover no Pikachu -- and no stone. as soon as they finally discover the mouse Pokémon, he"s just training. Team Rocket mirrors up, having stolen the stone, and encouraging Ash the Pikachu doesn"t need to change to defeat the new adversary. Unsurprisingly, they revolve out come be appropriate (and gain to do a quite penny marketing the stone!).
This doesn"t describe Pikachu"s aversion to evolution, yet Pokemon Journeys may have actually finally given a ethereal explanation. Season 23, illustration 1, "Enter Pikachu" revealed that Pikachu was originally a Pichu and also lived with a team of Kangaskhan who prospered to it is in family. Upon finding out the load he was placing on them, being lugged alongside a infant Kangaskhan that was stability outgrowing its mother"s pouch, Pichu chose to leaving -- and his feelings of gratitude caused him come evolve into Pikachu.
