History Main / CrystallineCreature

** The Syncopite is the Celestial, or diety, of the crystal element, and appropriately also embodies this trait. Atop its head is a tall column of turquoise crystals that is circled by floating rocks. These rocks smack the Syncopite's crystal head to make its music. When sleeping, the floating rocks rest on the crystal, making it resemble a geode.

* In ''TabletopGame/RocketAge'', are an organic crystalline species, and that's about all that is known about them.

* The Diamond dog (second form of the [[WreathedInFlames Carbon Dog]]) from VideoGame/EarthBound1994.

* ''Franchise/DragonQuest'':
** ''VideoGame/DragonQuestX'': The game introduces the Jia Kut Clan, a group of crystalline people that once invaded and destroyed the Eternal Cradle, before trying to destroy Astoltia, though they failed since Goddess Lutiana created a Shield that kept them destroying the world she just created after fleeing from them, causing Jia Gonuba, or rather [[spoiler:Jagonuba]] as he is now known, to take matters into his own hands thus starting the events of the entire game. In addition, there are various [[UndergroundMonkey "Jia" versions]] of monsters, such as Jiaticks and Jiademons, with versions of Dragon Riders, Silvapithecuses, and Balhibs also present in their ranks, as well as Jia Ruda and Jia Roda, 2 boss monsters that guard the Crystal Tower.

* In ''VideoGame/{{Toki}}'', we have Zorzamoth , a crystal mammoth that Toki faces at the end of the Ice stage. Averted on the Hd remake, with him being redesigned to being just a regular mammoth with diamond as eyes.

** Crystal Sentinels are golems made of quartz and rubies to serve as the PraetorianGuard for higher-ranking forces of evil, such as Sharella the Great Witch in ''Literature/CavernsOfTheSnowWitch'' and Bythos the Lord of the Abyss in ''Literature/SlavesOfTheAbyss''. They are extremely durable, have SKILL stats in double digits, and cannot be harmed by edged weapons like swords or axes -- adventurers will need to collect a [[DropTheHammer warhammer]] in order to smash these enemies apart in combat, or else die in an unwinnable battle.

* ''VideoGame/FTLFasterThanLight'': The Crystal Aliens are the ancestors of the game's Rockmen race, living in a solar system [[HiddenElfVillage separated from the main game by a devilishly hard to find wormhole]].

* ''VideoGame/KingsQuestVIIThePrincelessBride'': A crystal dragon appears in the Volcanic Underground, blocking the way for Rosella to get further into the volcano. It has lost its spark and is unable to make fire and, if you can retrieve one for her, she moves out of the way and grants you two key items in the form of a massive ruby and one of her own crystalline scales.

** Crystalline Entities, space-dwelling creatures resembling clusters of colorful, slender crystals larger than most spaceships, can occasionally be found in certain systems, and are hostile to every faction that turns up in their space. Destroying them and researching the aftermath allows the destroying faction to research the "Crystal-Infused Hull" technology.

* ''VideoGame/{{Stellaris}}'': Crystalline Entities, space-dwelling creatures resembling clusters of colorful, slender crystals larger than most spaceships, can occasionally be found in certain systems, and are hostile to every faction that turns up in their space. Destroying them and researching the aftermath allows the destroying faction to research the "Crystal-Infused Hull" technology.

* ''ComicBook/CrystarCrystalWarrior'': The crystal warriors, natives of a planet covered in immense deposits of precious minerals, resemble humans made out of clear crystal.

** ''StrangerOfParadiseFinalFantasyOrigin'': Jack's attempt to crystallize the Behemoth instead transforms it from a giant winged feline into the entirely crystalline Ur-Dragon King.

* ''Film/StarWarsTheLastJedi'': During their last stand, the Resistance takes shelter in a cave on the planet Crait, where the indigenous life has crystal-based. They generated a faint tinkling as they moved about.

** ''VideoGame/FinalFantasyV'': A group of four Crystals is fought as a boss. There's also a regular enemy with the same sprite called the Crystelle that inhabits TheVeryDefinitelyFinalDungeon.

* ''Manga/LandOfTheLustrous'': Like real minerals, when the Gems are formed their bodies are extremely rough and angular, needing to be polished and cut to achieve their "lustrous" appearances. [[spoiler:Phos]] is so badly damaged after being shattered they are just a mess of cracks and jagged pieces, barely holding themself together. However, they refuse to be repaired and their new, disturbing appearance is used to highlight their [[spoiler:FaceHeelTurn]].
