The rarest non-legendary (because those are obviously the rarest in any game) would probably be Feebas. You have to canvas a whole pond in Mt. Coronet fishing several times on EVERY SINGLE TILE until you’re sure a Feebas will not appear there (so, about 5-6 times on each tile). Once you find a tile with Feebas, you can come back to it as many times as you want to catch more—but here’s why I say they’re rare: the tiles shuffle daily. So if for any reason you want to go back and catch another Feebas for…say, natures or something, you’ll have to do the whole thing again if you dared to wait until tomorrow.

No, you do not need cheats to get the rarest Pokemon. The only way to get the rarest Pokemon without cheating is to go to a Nintendo Event, held every few years or so, and download the rarest Pokemon there. Otherwise, you would need cheats to get the rarest Pokemon.
