What is the most popular glitch in Pokemon Games? Especially in Gen IV and V.
Here is what I think. I think all the cloning glitches of GTS are really popular. Also, I believe the sky drop glitch has been abused to win in doubles. Overall, there really aren't any rankings. These are Gen IV and V
Hope this helps!
I think the most popular glitch is the good ol' Missingno. glitch in Gen. 1.
It also has a couple of different forms.
This link will tell you all about Missingno. and all of it's currently known data.
