The Glitch Unowns are Unowns that are glitched. Some look like versions of MissingNO (like the glitches in good ol' R/B/Y,) while others look like blocks with all the Unown letters except Z (A-Y,) still others look like fragments of blocks with all the Unown letters except Z (A-Y,) while others look like part "version of MissingNO" and part "Unown letter block," others are blank, and many of them can restart and/or crash your game. I don't have any pictures of the Glitch Unowns, but if I get any, I will put them on a zip and post it up here.

The code to change the first Unown in your Unown Dex is 01??24DC, where ?? is any Hex number between 00 and FF, but to find Glitches, don't enter 01 through 1A, as those are the real Unowns. Here are some examples of Glitch Unowns:

"Some look like versions of MissingNO (like the glitches in good ol' R/B/Y)" (01FC24DC)

"others are blank" (01FD24DC)

"others look like blocks with all the Unown letters except Z (A-Y)" (01FE24DC)

"others look like part 'version of MissingNO' and part 'Unown letter block'" (01FF24DC)
