missingo was weird when I caught it, it evolved into a snorlax :eyebrow: then another one I got evolved into Pidgey, man been years since I played pokemon thought well the old Red and Blue was playing emerald the other week but its just so boring nower days IMO
Weirdest thing is, Missingno sometimes catches itself. I noticed that if I do the glitch, next thing I know four or five of them are in my box. The only thing I noticed it messess up is the Records that show the pokemon you used for the eliete four.
I thought the real interesting bit about Missingno was the different pokemon it made appear on the Seafoam Island coast. I found Lv 143 Snorlax and 171 Mewtwos. Of course if you battle with them the level drops to 100, and they're not really any better, but it was pretty crazy
