A field guide to video game glitches

Fighting/Glitch Pokemon with 182 base Attack (beats Kartana's 181) and base Speed 2. Fully usable in battle.

Cannot learn Body Slam. No level-up moves. Set: Thunder Wave / Softboiled / Double-Edge / Horn Drill.

169 base Speed, faster than every real Pokemon except Regieleki and Deoxys Speed Forme. Base Attack of 0.

Cannot learn Thunderbolt or Substitute. Set: Psychic / Ice Beam (or Blizzard) / Fire Blast / Thunder. Its only level-up moves below 100 are Conversion at L17 and a glitch move at L8.

BST 699 with no stat below 130. Battles work, but its front picture is read from video memory, so what it looks like depends on what is on screen.

Swords Dance + 152 Attack is the play. Its summary shows no picture and plays Rhydon's cry, like every glitch past Pokedex number 151.

BST 715, above Gen 1 Mewtwo's 590. Its picture decodes the same way every time, and its four starting moves are real.

Lovely Kiss is a starting move, not from its learnset. Displays Normal/Ghost but typing is fake, no real resistances. Do not level it up: at levels like 51, 53 and 71 it tries to learn a nameless Super Glitch move. Set: Lovely Kiss / Earthquake / Thunderbolt / Body Slam.

94's twin: identical 715 BST, but its level-up learnset reads from VRAM, so learnable moves change with what is on screen.

Same TM list as 94. One of four indices whose learnset pointer lands in video memory, with 0xEA, 0xEB and 0xF6.

Bug/Glitch with 254 base Special, 100 points above Mewtwo. Stability test in progress.

Garden is stability-testing. Pass = ranked entry; fail = Nukes.

The famous one. Bird/Normal, 136 Attack, 0 Defense, 39 forms including two fossils and a ghost. Duplicates bag slot six by 128 and scrambles your Hall of Fame.

Does not freeze the game. Sprite scramble clears by viewing a clean Pokemon's stat screen. Stats come from far past the end of the base stats table; the two fossils and the ghost skip that read and borrow the last loaded Pokemon's stats.

MissingNo.'s identical twin with different rules: the same stats to the digit (136 Attack, not the 137 some wikis list), but it evolves into Kangaskhan or Clefairy, and a Level 0 'M freezes the game when withdrawn from the PC.

Old man glitch encounter; level 0 or 80 depends on trainer name. Feed a Level 0 one a Rare Candy before boxing it. Becomes 3TrainerPoke $ in Yellow.

Tied for the highest BST of any glitch Pokemon at 788, with seven relatives that share its stats entry. Freezes the game the moment one appears in the wild: its sprite size reads as zero, so the decoder never finishes.

Nukes tier.

Same 788 stats entry as 0xC7, and the same freeze the moment one appears in the wild.

Nukes tier.

No real species behind it (its Pokedex byte is 234, past the 151 real ones). Starts with a Super Glitch move, whose name and effect are read from whatever memory follows, so one move can freeze a battle or corrupt data.

Nukes tier.

A hybrid, not a nuke: its Pokedex byte is 6, so it borrows Charizard's sprite, types and stats under a glitch name.

Base stats are Charizard's: 78 HP, 84 Attack, 78 Defense, 100 Speed, 85 Special.

The glitch that started the channel in 2013. Garden's first upload, filmed at age nine.

Historic entry, the Glitchhouse's founding specimen. Original video on the channel (16K views).

A failed money calculation writes the byte 0x99 (the letter Z) to memory 200+ times: your name becomes Z's, your team becomes Level 153 Bulbasaur that only know Explosion, and saving can brick the file.

Escape with items only, never open the party, heal at a Center. Names of exactly 2 or 5 characters can survive with save intact. Emulator with backups only.
