Pikachu+Thunderstone=Raichu Eevee+Thunderstone=Jolteon These are the only 2 pokemon that evolve with the thunderstone in pokemon emerald
Yes you can. From a walkthrough, a person claimed that he received a Thunderstone from someone from Olivia City. It's a "she" that you have to battle and get her contact. Pretty easy though =]
Tynamo will evolve into Elektrik will evolve into Elektross with a thunderstone in Pokemon White.
