He's referring to cartridge hacking/editing. And Missingno DOES tend to evolve unexpectedly; as I recall, Chu is telling the truth.Pine said:Unless you're talking about the M pokemon, which are technically not new pokemon, there is no possible way for that to happen in R/B/Y/.

Now, missingno. doesn't turn into anything else, but there are a lot of rumors, even though they have been disproved.
It's also not a real pokemon and will never be one (in r/b/y that is, my game will include it as a real one!)
Blitzballchamp, it's called missingno. because it wasn't supposed to exist, therefore it's not real and wasn't assigned a pokedex number.
