In Pokemon LeafGreen, Missingo looks like a question mark and has no moves! If you try to attack with it,it will freeze your game, so don't catch it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
There is no Missingno. anymore.
Buy a game shark and cheat
pee wee Herman
If it shows up as a question mark it is the missind Pokemon, Missingo. Missingo really isn't a Pokemon but it is a glitch Pokemon.
You need the bad egg cheat then the egg will hatch and will crash your game. Pokemon put in by mistake. It was supposed to be a starter in a newer game, but they let it go. Trust me you don't want a Missingo, they suck anyway.
