Ick, there are so many glitches.
And why would you just rename Pokemon and say they're new Pokemon?
I couldn't even keep playing after I saw that.
If you want your hack to have new Pokemon, make some decent looking fakemon.
If you want the original Pokemon, keep the original Pokemon.
It's that simple.
Honestly, if you want to keep people's attention during the game, you have a lot of work to do.
