by relessing it
You can delete it by clicking it and pressing delete duhhh -miraih snipes
go to release
you cant delete your Pokemon from your party directly but you can deposit them into the PC at the Pokemon center or you can release them if you wish to get rid of them the option is in your PC i do believe.
Hold B, Select, and either Left or Right.
Up, b, and Select all at the same time. :)
on the page with lugia underwater press up+select+B
When you open a new game it will tell you what to do be aware lots of buttons
you can't i tried trust me. if you did delete your saved file and you had a Pokemon in the walker it will be there until the battery dies get a new one.
like Pokemon soulsilver and heartgold, you press down on the control pad, the select button and then b button.
no you can trade soulsilver pokemon to black
he is not in Pokemon soulsilver or Pokemon heartgold
POKEMON SOULSILVER come with a poke walker and the Soulsilver game
