Raichu never evolves. Unless you meant Pikachu, which evolves into Raichu. Or Pichu, who isn't in Leafgreen but evolves into Pikachu, then Raichu.
Raichu is the final form of Pichu, it evolves from Pikachu by Thunderstone. If you breed Pikachu for example with Ditto, you will get Pichu, maybe it works with Raichu, too.
Pikachu can evolve into a Raichu.
I don't get what you mean... But if you when what does Raichu evolve into the answer is: He doesn't evolve Raichi is the final evolution of Pichu... It goes Pichu > Pikachu > Raichu If that wasn't what you meant... sorry...
Pikachu evolves into Raichu. To evolve it, you have to use a Thunderstone on it.
Well Denkichu Is Not An Official Pokemon But You Can Make Raichu Evolve Into Denkichu By Giving Him 5 Thunder Stones And 15 Rare Candys then Fight 5 Random Pokemon Then Raichu Will Evolve Into Denkichu
Raichu, the evolved form of Pikachu, cannot evolve again. Also, as of December 2014, there is no official announcement of a Mega Raichu either.In order to evolve Pikachu into Raichu, a Thunderstone is needed.
if you have a pikachu,put a thunderstone on it and it will evolve into raichu
Well Raichu isn't available as a wild Pokemon in any of the games, so evolve Pikachu, or trade a Pokemon for Raichu.
You can't evolve Yanma in Leafgreen. This is because Leafgreen was made before Yanmega was made. So basically in Leafgreen, Yanma is a Pokemon that can't evolve.
you can evolve pikachu into Raichu and Eevee into Jolteon
In Sapphire, there is Electrike, Manectric, Pikachu, Pichu(breeding), Raichu(evolve), Voltorb, Electrode, Plusle, Minun, Magnemite, Magneton, Chinchou, Lanturn, Zapdos(trade from FireRed or LeafGreen), and Jolteon(trade from FireRed and LeafGreen).
Pikachu ONLY evolves into a Raichu when you give it a Thunderstone.
