Steve Watts posted a new article, Pokemon X & Y hacker discovers unobtainable new creatures.
A Pokemon X & Y hacker seems to have uncovered three as-yet undiscovered Pokemon likely to be given out as event creatures.
I wonder if there is still a missingno, like in <a href="http://pokemonepisode.org/">Pokemon</a> Red and Blue version
You mean that programming place holder only discovered by exploiting flaws in the game that allowed access to values not meant to represent pokemon?
Missingno was never an actual pokemon, clearly.
So no, I think not.
