My name is Jared and the real way to catch Missingno.
First,the good things about catching Missingno is that he/she or whatever you want to call it, has a very high attack.
The bad things about catching Missingno:
Missingno is a glith and a glitch is like a virus in a computer and if you cath this glitch pokemon it will erase your old saved data and its like having to restart your game, and also it will NOT let you save any other game after that.Also Missingno evolves into a khankiskahn if you give it a rare candy.
Missingno has a 13 defense. How do I know well I used a weedle and used a 5 power attack twice and the next weakest move was three power so I used the move and made him faint. So that is how I know. O.K. where is Missingno I will get to that in a second. there is so many bogus cheats out there even to this day but now that I have stepped up to the plate I am going to help all in need of POKEMON CHEATS and HINTS!
O.K. Missingno is on cinnabar island ok heres how to do it. First, Fly to virdian city, go left from the pokemon center until you hit the white trail the go up and talk to the man who shows you how to catch a weedle. He will ask you if you are in a hurry say no and he will show you how to cath a weedle. Then fly to cinnabar island and go right until you hit the shore and then put whatever item you want 100 more of in the sixth item slot. Pick the pokemon on your team that knows surf and surf up and down.Right about now I would put your strongest pokemon at the of your team because there is over L:100 Pokemon. I have caught a level 80 golduck, a level 132 mewtwo and now back to level 100 golbat because if the over 100 leveled pokemon gains exp. points it will go back to Level 100. once you run into missingno the screen will go black for 5 seconds. Use any attack to destroy Missingno go back on shore check 6th item there will be a symbol that means 100 of that item. GOODBYE, GOODLUCK

Sincerely,
Jared
