I have looked around, but nobody seems to know; not even the people with cheats. I have a feeling he is not in the game anymore, along with N, and was meant to forget about.

After finding the 6 Sages(Ghetsis and N must be in Sinnoh), you go onto your adventure,completeing the PokeDex.
You can only find SIX sages, Ghetsis and N disappear. Idk why they made it like this, Maybe they will make there first franchise from this.
You don't.
Well you defeat alder and he will register your pokemon on the hall of fame. After that you have to find all seven sages including ghetsis.
Chargestone Cave, Relic Castle, Dreamyard, route 18, Cold Storage, Route 14, and Ghetsis is already done at the team plasma castle.
Sadly after months (minutes :D ) of research, I have finally accepted that Ghetsis cannot be found even after you find all the sages in Pokemon Black/White. There are rumours though that he has been spotted near Black City/White Forest, depending on which game you have.
He is in front of the white forest or black city by the bridge.I found all 6 sages,but he is not there.
You don't.
No where. He just went of.
Gehtis disappeared. You cannot find him anywhere unlike the other sages.
you cant find him after you find all seven sages. its sorta like the end of the whole story after you find them all. Hope the helped :)
Looker goes away after you find the Seven Sages.
