go to the seafoam islands after defeating the other fourteen gym leaders
the 15th gym leader in soul sliver is blaine and he uses only fire type pokemon
professor elm gives it to you after you beat Clair (the dragon gym leader) i think if this is wrong please correct it
He's in the seafoam islands.
The Kanto gym leaders come in no particular order, but Blaine is typically the last gym leader fought, and also the second to last gym leader appearing on the Trainer Card.
A Magmar level 54, a Macargo level 54, and a Rapidash level 59.
You can battle all of the gym leaders out of order in the Kanto Region. Thus, the perspective of the 15th gym leader will change from person to person. Chronologically, Blaine is the 15th gym leader, and he is in the Seafoam Islands, and is up the first ladder you see when you enter.
once you beat the other 14 leaders go to route 25 and she will be ther
you must frist go to seafoam island where blaine is, he is the 15th gym leader, then go to cinnibar island and a character who is behind the Pokemon center will then say that he is the last gym leader, once you have talked to him he will go to viridian city gym, he is the last gym leader. this is for heartgold and soulsilver :) hope this helped.
After you beat Brock in Pewter city head south through Viridian and Pallet. Surf down to Cinnebar where you will find Blue/Gary inspecting the aftermath of the volcano eruption. Surf east from there to the seafoam islands and explore the cave where you will find Blaine, the 15th gym leader. Go up the ladder as soon as you enter.
The water Pokemon gym leader is in Pastoria City.
were is the fifth gym leader
After you beat the 15th Gym leader, you have to go to Cinnabar Island then you talk to Blue who is the only person on the island then he tells you to go the the Gym in Viridian City, where you battle him after getting through the maze.
