i don't know i don't thing you can but if you can it would be at the power plant
you have to get an elekid
You can find it on some wild Elekid.
You will need to evolve your elekid at lv. 30. There are no elekid's in diamond unless you have fire red inserted, then you can find them at route 204.
Because it simply does not appear in any of the given locations. You can only catch Elekid in FireRed.
none have elekid you will need to migrate
You have to have the national pokedex, because you cant find a lot more Pokemon without it. :)
You can evolve Elekid once it hits Level 30.
When Elekid is level 30, it'll evolve to Electabuzz.
You can get the Electrizer in Pokemon Diamond and Pearl from wild Elekid close to the Valley Windworks. In order to find Elekid, you should have Pokemon LeafGreen in your GBA slot of your DS.
wild elekid
