|Bulbapedia also has an article about ????? (disambiguation).|
????? may refer to:
- Glitch items in Pokémon Red, Green, Blue, and Yellow.
- Glitch Pokémon in Pokémon Gold, Silver and Crystal.
These glitch Pokémon have varying front sprites. Outside of battle, an opposing ????? will use the tiles in the top-right picture. Inside of a cave, an opposing ????? will use cave tiles. ????? have glitchy Pokédex entries, but some may freeze or reset the game. All ????? have a footprint with their number written in it.
The back-sprites for all ????? are the last Pokémon sent out or if no Pokémon was sent out in the session; it is the player character's "back sprite". A difference is that the 'Pokémon' or 'Trainer' sprite will use the ?????'s palette.
The palettes are as follows:
- 00: Brown
- FC: Yellow
- FE: Yellow
- FF: Silver
If the player opens the bag and closes it, the game will attempt to use the bag as a source for its sprite.
In Pokémon Gold and Silver, but not in Crystal, encountering a ????? in the wild will cause corruption to memory addresses D03B-D03F (excluding D03E), by writing FF to them. The cause of this is undocumented. This corruption means that the battle will be turned into a link battle (where items are not allowed), and the game will lockup on the "Waiting...!" message upon trying to fight, switch to another Pokémon, or run.
