Use the Pokemon locator. In Pokemon Indigo I own a Rayquaza. Two of them. And if you want to add me my username is DialgaLiker. Rayquaza is not rare. It is super common in Indigo. Even use rooms in Pokemon Indigo.

you can't find N in pokemon indigo. N is the second main antagonist (=villain) in pokemon black and white.
