Ash's Pikachu, Squirtle and Bulbasaur have never evolved and they never will.
-Pikachu is a main character and therefore his appearance changing would be a ton of extra work, also it would not look right for the main character to change.
-Bulbasaur and Squirtle are no longer with Ash and Bulbasaur currently resides at Professor Oak's lab while Squirtle stays with the Officer Jenny in charge of the Squirtle Squad.
To evolve a Pikachu in-game, use a Thuderstone on it.
To evolve a Bulbasaur, level it up to level 16.
To evolve a Squirtle, level it up to level 16.
As seen in "Bulbasaur's Mysterious Garden" Bulbasaur tried hard not to evolve.
In the episode "Electric Shock Showdown" Pikachu had a chance to evolve into Raichu, but did not want to.
Ash's Squirtle has shown no opinion towards evolving further but because of its ties to the Squirtle Squad and its friends there, it's unlikely it will evolve.
episode 1337
Bulbasaur does not evolve during the Pokemon anime series, there is an episode where Bulbasaur is about to evolve, but he restrains himself from doing so, because it didn't wish to evolve
Ash's Pikachu will not evolve because Pikachu chose to stay with Ash and gain more experience and in the episode that Ash had battled Lt. Surge Nurse Joy gave Ash a Thunderstone but pikachu don't want to evolve and Brock said that pikachu has more speed than Raichu
It Evolved prior to the episode Staging a hero's Welcome!, When it was traveling with May in Jonto!
Bulbasaur does not evolve with a stone. Bulbasaur needs to get to a certain level, then go to "Luminous spring", select Bulbasaur, then select "evolve". If YOU are Bulbasaur, then you must get Manaphy and Palkia to join your team, and then go to "Luminous spring".
well ash's squirtle will never evolve because of the squirtle squad and his bulbasaur chooses not to evolve, in episode 51 bulbasaur was going to evolve along with a large group of other bulbasaur but it chose not to, so it never will.
not really..if you evolve squirtle charmander and bulbasaur andget rid of jigglypuff and clefairy and replace them with a rock type and a flying type then its pretty good
episode 1337
pokemon yellow you start with pikachu, you don't choose in this one. you get pikachu at level 5 and it will not allow you to evolve it even with a thunderstone. squirtle, charmander and bulbasaur you have to get from people and i think you get them all at level 5
It does not evolve into Bulbasaur. It evolves into Wartortle at level 16, which then evolves into Blastoise at level 36.
Bulbasaur does not evolve during the Pokemon anime series, there is an episode where Bulbasaur is about to evolve, but he restrains himself from doing so, because it didn't wish to evolve
You automatically start with pikachu. Later on in the game, talk to people and you can get bulbasaur, squirtle AND charmander. Your rival will get eevee and will evolve it depending on whether you win or lose the first two battles with him. You can turn around and "talk" to pikachu, and he will show how happy he is! HOPE IT HELPED!
Episode 14 - Electric Shock Showdown
ash keeps all of his old Pokemon including bulbasaur but they are in kanto, johto, and hoenn regions and they are in his PC boxes with proffessor oak. technically ash still has his Pokemon. the should come up with an episode when ash sees all of his Pokemon he ever caught. hope this helped!
May's Bulbasaur did not evolve in an episode, it evolved while she was competing in Pokémon Contests in the Johto region which were not shown in any episodes.
Go to luminous spring with a moon stone in your pack
