Eventually there will be an Engima Stone event in America. Once you get the stone, go to the Pewter City Museum and talk to Steven Stone, he'll take you outside and Latias will appear
If you mean the Pokemon Forslass, an evolvmentfrom Snorunt, I can help, but if you mean Fortress, I can't. What I do know about Forslass,though, is that you must have a Snorunt that is a female and a dawn stone. Once you have all the requirements, use the dawn stone on the female Snorunt and you will obtain Forslass.Imformation above obtained fromwww.pokemon.marriland.com
Once you get the water stone. Eevee can evolve into Vaporeon at any level. Go to Bag > Items > Water Stone > Use > Eevee.
Once you have eevee from that girl in hearthome city ,give it a fire stone.
Well, after you get all 16 badges, beat Red, and choose your Hoenn starter from him at Silph Co. in Saffron City, go to Pewter City and head north to the museum. Once your there just go and talk to Steven and then go to Silph Co. in Saffron, and talk to Steven and he will offer you a Beldum for a Foretress. The Beldum is the same level as the Foretress you give him, and is holding a Dawn Stone.
Roselia only evolves once you give it the Shiny Stone.
Yep
Once you give the doll to the copycat girl.When you come out Steven will talk to you about Latias.Use your poke'gear to find her.She will be roaming Kanto.
"Steven" is typically spelled "Stéphane" in French.
Steven Stone will trade you a beldum in return for a Forretress (you need to evolve Pineco upto level 31) at the Silph co building, once you talk to him in the pewter city science museum)
you can only use 1 leaf stone once :)
you can't get torchic. you can only get him in sappfire or ruby Wrong. Once you beat the game and defeat Red at Mt. Silver, go to Silph. Co in Kanto and inside will be Steven. He will ask you to choose a stone. (Choose the yellow stone for torchic, green for treeko, and blue for mudkip.)
