Near 21 level. I have Pikachu of 21 level and it has recently learnt slam.
Pikachu learns Thunderbolt at lvl 26 in Pokemon Yellow.
Yes, it learns Thunderbolt at level 26.
There is No Specific Level Pikachu Needs a Thunderstone to evolve
Pikachu learns Electro Ball at Level 18.
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 doesn't evolve you have to use a thunderstone, but in Pokemon yellow you can't do that to your pikachu unless you get another one from Red or Blue.
Thunder, which it learns at level 41 (level 43 in Red and Blue versions).
Pikachu learn electro ball at level 18
maybe the 3 legendary dogs i think but there is a chance to be pikachu if its in level 81
Just has to be level 25 or higher, and you have to have HM01, cut.
level 70
Pikachu learns thunderbolt at level 26.
