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.
if you have a pikachu,put a thunderstone on it and it will evolve into raichu
No Raichu cannot be found in the wild.
none but if you ment raichu then pikachupichu->pikachu->raichu
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
