==In later generations==
Arbitrary sprites are possible in Pokémon Ruby and Sapphire. All glitch Pokémon’s palettes are indexed out of bounds from the array holding each species’ compressed palette pointers. These pointers can end up in Pokémon storage data, which allows the player to manipulate data within their boxes (through ACE or by save editing) so that when decompressed, the “palette” data will overwrite the decamark sprite in memory. It should be noted that this same technique is not possible in Emerald or FRLG because of how memory is laid out differently.
Arbitrary sprites are theoretically possible, but no vulnerability to do it has, as of yet been documented.
