Missingno
I'm not giving a action replay code, but it's a cheat using one. Use the walk through walls cheat to enter the two player battle area and step on one of the places that starts the two player battles.
Missingno should challenge you as a wild pokemon.
I don't know what will happen after, if you can catch him, or if this even works. If it does please post, and those of you who catch him (or even trys to catch him without any side effects) please post as well.
