you got to beat all the Pokemon gym leaders in kanto other then blue,then talk to him
you must beat all other gym leaders
His name is Blue Posted By Tom587
There are 8 gym leaders in Pokemon lake.
In pokemon soulsiver Blue is on cinnabar island but you can only battle him when you defeat all of the gym leaders.
Machamp, Arcanine, Exeggutor, Rhyperior, Tyranintar, Pidgeot. I made a link of all gym leaders, blue the gym leader is at the bottom.
the only problem is you cannot catch a gym leaders Pokemon !!!!
To get the 8th Gym Leader to return to his Gym in Viridian City, you must defeat all 7 other Gym Leaders.
There are different types of gym leaders and each gym leader has a different pokemon type.
You can fight the Kanto Gym Leaders in any order, except Brock, Blaine, and Green/Blue.
you get it from blue when you defeat all 16 gym leaders
You cannot rebattle Gym Leaders.
