'''?????''' are [[glitch Pokémon]] which appear in [[Generation II]] games. The game resorts to the error handler "?????" to name the non-existent {{OBP|Pokémon|species}} with index numbers 000, 252, 254 and 255 if they were to appear (not including 253, since index number 253 is used for [[glitch Egg|Eggs]]). All ????? have no cry.
