No

no
No he does not turn into a pokemon.
if you mean "pikachu" then no, pikachu is his starter and it would spoil pokemon in general if he left pikachu.
Yes
Cerulean city
Pokemon number 1 : Bulbasaur If you mean the first Pokemon concept, Pikachu.
Pikachu will evolve into Raichu when given a thunder stone. If you mean Ash's Pikachu, then it very unlikely he will evolve his Pikachu, as Pikachu is the Pokemon Franchise's mascot.
Yes one of the most . Me? he is me and all my friends favorite! I have collected almost every Pokemon game and Pikachu is best.
In Kanto's Cerulean city
The first Pokemon ever to exist was arceus in the Pokemon legends. But bulbasaur was the first Pokemon in the pokedex and drawn. But pikachu was the first popular one.
Pikachu has never been to Yoshi's dimension, nor has Yoshi ever been to Pikachu's. (But there are rumors that Yoshi has been to Pikachu's dimension with Ash and friends and is often mistaken as a Pokemon!) Actually pikachu does meet Yoshi in Super Smash Bros. Brawl.
