They have before but only temporarily.
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.
In one episode, Ash lets Pikachu stay in the forest with the other pikachus. after that, pikachu finds Ash and comes back with him.
In episode 39, "Pikachu's Goodbye", Ash attempts to release Pikachu to look after a group of Pikachu that had just been targeted by Team Rocket. But Pikachu returns to him at the end of the episode. That was the last time Ash tried such a thing.
Yes
Ash.
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.
mabye sometimes when ash does something wrong. ya in season one ash starts looking at other pikachus and pikachu catchs ash with another Pokemon and a safarie ball in his hand and pikachu got really upset.
no, if you don't believe me check out ash's greatest moments
Ash kill Pikachu because Pikachu is useless.
No, he will fall victim to bestiality and impregnate his 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 pikachu is ash's best friend.
Because it was the first Pokemon EVER MADE! acually the pokedex says that pikachu is the 25 Pokemon pikachu is ash's first Pokemon
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.
YES VERY!!!!!!!!!! He is a Bikachu. If he gets hit with 3 Hyper Beams, he is still battling! they make him LOOK strong. I say Ash and pikachu are the dumbest and weakest team ever!
No, Ash and Misty do not kiss in a Pikachu movie.
