Raise Pokémon and work on your Pokédex. The games finished really.
Zekrom is exclusive to Pokemon White, you will need to trade it.
Well you could go to white forest on white and find ghetsis on black go to front of black city
At black city but it's hidden somewhere therE
go to www.pokemon Black & White-New pokemon.com to find out.
Ghetsis will be in front of Black City if you are using Pokemon Black, and White Forest if you are using Pokemon White.
he only is in Pokemon platinum and Pokemon black and white in Pokemon platinum you see him in jubilife city, and I think maybe at Team Galactic HQ. in Pokemon black and white after you beat the elite four, he is looking for the seven sages. after you find all seven sages he'll talk to you and he'll arrest the 7 sages. you will never see him again after that.
An event
If you mean after you find the other sages . well you cant find him ever again you will have to wait for the sequel of pokemon black and white so really you cant find N or Ghetsis ever again in your currant pokemon game
To get the super rod you have to beat N and Looker will give it to you when he asks you to find the 7 sages.
you can't
Yes. You find zekrom in Pokemon white and the white Pokemon in Pokemon black.
Gone forever =(
