Placeholder items are often left in the game's code to prevent it from crashing if the data is accessed, such as the [[Teru-sama]] item in [[Generation II]]. Likewise, other generations have placeholder items, with most appearing at the end of the item list, though a few, likely removed during development, appear in the middle.

Likewise, other generations have placeholder items, with most appearing at the end of the item list, though a few, likely removed during development, appear in the middle.


Often, placeholder items change into real items ([[key items]] or otherwise) in later games of a generation. The [[GS Ball]], [[Clear Bell]], and {{key|II|Egg Ticket}}, which only appear in {{game|Crystal}}, are programmed into the games' [[List of items by index number (Generation II)|internal list]] where Teru-samas existed in {{game|Gold and Silver|s}}, and will, if they are hacked to be held by a Pokémon being traded to the earlier games, transform.

Thus, glitch items that become real items from a later game only appear in [[Generation II]] and [[Generation IV]], as all items not present in {{game|Ruby and Sapphire|s}} that were reintroduced in {{game|FireRed and LeafGreen|s}} and newly introduced in {{game|Emerald}} appear at the end of the list. They would cause a copy of Ruby or Sapphire to crash when it is selected, as they are beyond its item list. Generation II is the only generation in which all new items replace glitch items in the middle of the item list, thus not causing a permanent problem if transferred, as the {{DL|Legendary artifacts|Griseous Orb}} is the only item in Generation IV that is programmed at the same index number that a glitch item is present at in {{game|Diamond and Pearl|s}}, while the other items introduced in {{game|Platinum}} and reintroduced in {{game|HeartGold and SoulSilver|s}} are after the end of the Diamond and Pearl list, and thus crash the game if the glitch item in their place is selected in a game they do not exist in.
