...You forgot about the Mew Glitch, the Cut Glitch, and the other 5 glitched Pokemon. :3
I know all about that stuff, Bro. I can do PVM Modding, HEX coding, and everything like that, so I know what a hacker / cheater can do.
This is a glitch, which is a slip-up in the game that the developers couldn't fix, or never even noticed. It's fair game, and personally, I don't think a glitch should be frowned upon, unless it severely ruins game balance (The floating glitch in MW's Nazi Zombies is a clear example of an unfair glitch).
