nothing it's just a field move
no:) Eer... Right. You -could- get Secret Power in Pokemon Diamond, but I don't recall where I've obtained it. And I think you use it in the Underground if you have Wi-Fi. You find it in Amity Square. :]
in Pokemon diamond you can only use it in battle since your cave/house/thing is underground
You can find the TM Secret Power in Pokemon Diamond in the lower western part of Amity Square. It can be found roughly south of the man with the Pikachu.
in Pokemon diamond and pearl just go on your udventure and you will find it but in Pokemon sapphire,ruby it's hard to get it
There is no secret Pokemon in diamond and pearl but there are ways to get Pokemon you cant catch on diamond and pearl. For example manaphy. You must clear the manaphy mission on Pokemon ranger. Goodluck with the game!
No it is not
You can only get the secret key in Pokemon Platinum
Pokemon Diamond Pearl and Platinum are games in the Pokemon series. There is no secret store in Pokemon Pearl version.
yea......there is three
arceus
No there is no secret store I know that for I have beaten the elite four 20 times and have searched every corner of Pokemon diamond's world.
You can't, unless you mean secret base. You have to have a Pokemon with Secret Power. Use Secret Power in front of a tree or an indention in rock.
