...first you must beat the Elite 4.then you will go to fight area.Get national dex and go to resort.then travel to survival.after that if you own Dialga/Palkia, they will leave you and some major graphic stuff will happen.then you can go to Johto.then hoenn after that.
You can't get into the hoenn region in Pokemon diamond. It's a 1 region game and that region is SINNOH! BY THE WAY HAVE YOU HEARD OF POKEMON X AND Y
It's not a Hoenn Pokemon. It's actually a Sinnoh Pokemon, being introduced in the 4th generation games (Diamond/Pearl/Platinum).
sinnoh
No because it is a sinnoh Pokemon not a kanto, johto, or hoenn
Zangoose, but it's not in the Sinnoh region. So it's in the national dex. Its in the Hoenn region.
No, Unova, Sinnoh, Hoenn, Johto, and Kanto are not pokemon, but are the reigons of ¨pokemon world.¨
Jubilife City is located in Sinnoh, not Hoenn. Since Pokemon Sapphire takes place in Hoenn, Jubilife City is not accesible. You can buy a copy of Diamond, Pearl or Platinum in which travel through Sinnoh.
no, in Pearl as well as Diamond and Platinum, you can only be in the Sinnoh region
Yes,you can but you only get rare Pokemon from sinnoh and hoenn.
Regigigas is a Sinnoh pokemon. Not a Hoenn.
Duskull is a Sinnoh pokemon as in pokemon platinum you get darkrai which is the evolution of duskull.
I think you're mistaken. Petalburg is a city in Hoenn, not Sinnoh. You can't get there in Pearl/Diamond.
