that is actually true wshere is he well of course he at galactic headquarters
you have to beat all the gyms before the harthom one
go tospear pillarafter rescuing the lake Pokemon before you get to dialga you must beat mars, Jupiter and the head of the team galactic the you will be able to battle him
If You have all the other Pokemon you should be able to work it out quit easily that its the one before the evolved Pokemon or the one that evolves from that Pokemon. I have Pokemon diamond and that's how i used to do it. but Pokemon 45 on Pokemon diamond is Burmy and it is a grass type Pokemon and quite easy to find in forests and pathways and trails. they mostly live around eterna, floaroma, oreburgh, solaceon, celestic and pastoria city !!
go to veilstone city if you want to take the easier way as long as u are gettin there before nightime or you can battle and get exp points! then between there and pastoria city earlier you would see team galactic blocking the entrince after you beat the gym leader in pastoria before that two fishing men are blockin it but its worth it
In order: Orebourgh City, Eterna City, Veilstone City, Pastoria City, Hearthrome City, Canalave City, Snowpoint City and Sunnyshore City. You will come across Hearthrome BEFORE Veilstone but in Pokemon Diamond the Gym Leader (Fantina) will be out.
if you go to the gateway between the route before pastoria and the route before hearthome (i think, otherwise veilstone) and you use the itemfinder right out of the doorway you will find it
In Diamond and Pearl in order to get into the Hearthome Gym you have to beat Roark, Gardenia, Maylene and Crasher Wake and deal with the lone Team Galactic Member standing outside of the Great Marsh entrance in Pastoria City before you can go into the Hearthome Gym.
Before you face it you should train up your pokemon,if you brought turtwig then it will be hard because the leader has a skuntank or purugly which is a poison type which is super-effective against grass-types
Pokemon Fire red and Leaf green- After saving silph.co Pokemon Emerald- team aqua hideout Pokemon Diamond, Pokemon Pearl and Platinum- After defeating Cyrus at veilstone galactic base Pokemon Heart gold and Soul silver: Right before Ho-ho and Lugia
You will fight your rival at - East of Jubilife City (after you give the parcel to your rival in the Pokemon School) Hearthome City (after you talk to your mother in the Pokemon Contest Hall) Pastoria City (after you beat the Gym Leader and talk to the Galactic Grunt) Canalave City (about two or three steps on bridge) Pokemon League (before you talk to the person blocking the entrance)
You have to go to Veilstone City to the headquarters of Team Galactic. and the man before the headquarters has the Storage Key. with this key you have to go to the Warehouse (at the top on the left side), also in Veilstone City.
