Shiny Pokémon
Shiny Pokémon are rare Pokémon that possess a different color palette than normal members of their species.
Odds
In most dungeons, any Pokémon that spawns has a 1/1024 chance to spawn as a shiny Pokémon.
In a Monster House, the odds are greatly increased, with every Pokémon that spawns having a 1/32 chance of being shiny.
Preset Pokémon, such as bosses or NPCs, will never be shiny unless specifically set to be shiny by the creator of that dungeon or mod.
Gameplay Differences
Whenever a shiny Pokémon first spawns, a sparkling animation will appear on top of it. If playing as a shiny Pokémon, this effect will repeat at the start of every floor, and every time that Pokémon is made team leader.
Shiny enemy Pokémon have a differently colored icon on the map, having a more purple or magenta hue as opposed to the usual red. They also have a star next to their name in the message log. Player-controlled shiny Pokémon do not possess these differences.
Shiny Pokémon have no differences in stats, AI behavior, or experience gain compared to other members of their species.
Roguelocke
In Roguelocke mode, it is possible to customize all aspects of your starter Pokémon, including whether or not it uses its normal or shiny coloration.
If challenging a Roguelocke dungeon that allows team transfer to the Player's main save, several restrictions are put in place if the Player chooses to start as a shiny Pokémon. Under normal circumstances, if the Player successfully clears a dungeon, all members of the Player's team can be sent to the Player's main save, regardless of whether or not they fainted or were sent to assembly.
If beginning the dungeon as a shiny Pokemon, that Pokemon can only be transferred if it was never sent to assembly, and did not faint without being revived. If it was replaced and sent to assembly at any point, or it was in the Player's final party but had fainted while another surviving member cleared the dungeon instead, the shiny starter will not be transferred along with the other members.
