You cant get one on B/W
I'm sorry but you can't a raichu in pokemon black or white. The only ways to get one are to trade or poketransfer.
You don't get raichu as a partner pokemon in pokemon ranger 2. But you can get him as a friend pokemon.
Well Raichu isn't available as a wild Pokemon in any of the games, so evolve Pikachu, or trade a Pokemon for Raichu.
You'll have to transfer one from a 4th gen game. There are NO Pikachu, Raichu, or Pichu in Black or White. It sucks...
Raichu is weak against ground types.
You can't find a wild Pikachu, Pichu or Raichu in pokémon Black and White. You have to transfer it from an other game.
none but if you ment raichu then pikachupichu->pikachu->raichu
if you have a pikachu,put a thunderstone on it and it will evolve into raichu
No Raichu cannot be found in the wild.
Raichu never evolves. Unless you meant Pikachu, which evolves into Raichu. Or Pichu, who isn't in Leafgreen but evolves into Pikachu, then Raichu.
You envolve Pikachu
