Chibi's Hangout

If by cheating you mean that you have to trade with other players, then yes!

No. That is not what I meant. I meant there are some pokemon that you cannot obtain unless you do DRASTIC things or just flat out hack. Meaning pokemon that are location specific (IRL locations), given out on certain days, ect. If you can't get to these places or be there at these days, these pokemon cannot be seen, let alone obtained. That's why they are impossible to get.
