mew2 is the rarest
Corsola can be fished with the Good or Super Rod during morning or day. Kingler can be fished with the Super Rod at any time. That's about the rarest it gets. :)
The rarest Pokemon is generally considered to be Mewtwo, as it is a legendary Pokemon that is difficult to obtain in the games. Mewtwo is often found in special events or as a reward for completing challenging tasks. Its rarity is also due to its powerful stats and unique abilities, making it highly sought after by trainers.

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.
