I haven't really seen missingno in the game, but if that's his in-game name it was probably put in there in case of a glitch. So technically he might be in the database in case of an error or something...but if his name is ? then it's a sprite glitch.
I remember this one glitch called "Glitch City"... I don't remember the whole thing but the gist of it is: you go into the safari zone, do not take a step instead save, go back in, say no, go back out, fly to cinnabar, and the entire island turns into a green glitch city. Pikachu doesn't follow you--it's more like a house of mirrors: pikachu will pop up in different places and walk in random directions and disappear udner tiles. You can still surf and everything... I think that's the glitch, I found it online and tried it. Didn't do anything to my game but I didn't save there.
No, I read up on the bulba wiki.
There are like, 22 missingno.
It was done on purpose, just getting it wasn't done on purpose.
Also, there is some generator on the bulbawiki site, that allows you
to catch whatever pokemon you want by your players name on Red/Blue when you do the missingno cheat.
I think you can capture Rockets and Gary and the other trainers.
Either that, or they just enter a pokemon battle with you.
BTW is there really an item called wardensglasses in G/S/C to open the safari zone? I heard the old man in...where is it...goldenrod or something...the town with the casino and radio tower, the old man wandering around near bill's house is the safari warden on vacation. Is that true?
No, no way to get on the safari zone. When I looked up glitch city, they said it couldn't be done in Crystal, Gold, Silver because no access to it.
