the Pokemon must be transferred because u need those Pokemon to complete your pokedex but you don't have to transfer if u don't want to.
hope this helped
It is not possible to change the in-game region on Pokemon Emerald. Each Pokemon game is coded to be set in only one region. This means only data for the Hoenn region exists in Pokemon Emerald. Pokemon Gold, Silver, Crystal, HeartGold and SoulSilver are the exceptions as they are set in Johto and Kanto.
you cant
you can't
The region that you transferred it from to before to Pokemon Black or White will be displayed. For example, say if you transferred a Poochyena from Pokemon LeafGreen to Pearl, and then from Pearl to Black or White, it will say the follwoing: POOCHYENA Sinnoh Apparently arrived at Lv. 12
no,there is no other reigon in pokemon black and white.
Mostly likely, Pokemon is too profitable to stop making games at this point.
Maybe
U CAN NOT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

You can't. Unova is the only region for Black and White.
