The region "Orre" is the region found only in the Pokemon Nintendo Gamecube games such as Pokemon Colosseum and Pokemon XD Gale of Darkness. These two games are much different from the hand held games.

Orre?

the only regions i know are:

Kanto = Red, Blue,Yellow, Fire Red, Leaf Green and Pocket Monster Green.

Johto = Gold, Silver, Crystal, Heart Gold and Soul silver (also Kanto).

Hoen = Ruby, Sapphire and Emerald

Sinnoh = Diamond, Pearl and Platinum

and the new one Isshu = Black and White

There are likely more, but these are some of the hand held games.

pokemon colloseum and pokemon XD gale of darkness

Colloseum = First part

XD = Second part
