Pikachu. No question about it.
luigi's best friend is Yoshi and Mario
Ash's first Pokemon was Pikachu, he was suppose to choose from the three originals, Bulbasaur, Charmander and Squirtle, but arrived too late, so he was forced to choose from a just currently caught and unstable, Pikachu, which now is his best friend in every season.
They are both 'good guys' in the same series, so presumably, yes.
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! I would have to say so. Every since Mario found Yoshi, they have been friends.
They're best friends ^-^
Yoshi and gold dust
Because they are best friends.
A mix between a Yoshi and a Pikachu is called a Yoshachu. It has it's normal Yoshi body with Pikachu's tail, ears and cheeks. It's belly is yellow as well. In order to give birth to a Yoshachu, you must have a female Pikachu and a male Yoshi to make a baby together. If you want to learn more about a Yoshachu, please type the following question: "Can a Yoshachu use Pikachu's attacks?" Thank you for your concern! :-)
If you go on YouTube and search pikachu vs raichu they are not friends then after they fight they become friends
