Crystalline Creature

Living creatures with a faceted, crystalline appearance. In some cases they can simply happen to have skin, scales, or similar structures that look like jewels or gems; more often, however, they're made out of living crystals. In cases where these beings are made out of a solid block of crystal, it usually isn't entirely clear how the rigid angles of their "skin" would flex as they move, but the MST3K Mantra is useful here. Animators will usually find ways to fudge this so it isn't immediately obvious that the facets have to bend when the character moves. In other cases, the being in question instead resembles an assemblage of rigid but distinct crystals or gems, with movement happening at the "joints" where these meet. Some such creatures, however, are simply regular, living crystals without any body parts, additions or ability to move, save perhaps by levitation.

Crystalline Creatures often don't need food and drink like humans do, or at least not the same types — if they feed at all, they typically consume mundane gems or other minerals. Their precise makeup also varies; most are made out of non-specific "crystal", but they may also be identified as being made up of specific mineral types or, less commonly, of other crystalline materials, such as ice, or non-crystalline but rigid, shiny and transparent ones such as glass. Regardless of type, these beings are also fairly rare, more so than "regular" masses of living inorganic matter. More often than not, they're encountered in out-of-the-way, mineral-rich places such as Crystal Landscapes or Elemental Planes associated with earth, rock, or crystals. In combat, their abilities may involve Gemstone Assault, while their crystalline bodies may be difficult or impossible to harm in most conventional ways but prone to shattering under blunt impacts or great force.

Subtrope of Rock Monster (which covers all beings made entirely out of rocky materials) and Gem Tissue (which covers all cases where at least a portion of a living being's body is made out of or contains gemstones). This can often overlap with Elemental Embodiment, as it's not uncommon for elementals associated with earth or crystals to take this appearance. Overlap also occurs with Silicon-Based Life when the creature is made from a silicate mineral, such as quartz or garnet. Not a prerequisite for Crystal Dragon Jesus.

Examples

Anime & Manga

• Future Card Buddyfight: In its default form, Gemclone looks like a tentacled mass of jagged lavender crystals until he copies another monster's Super Mode.

• Land of the Lustrous: 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. The Mohs scale is taken into account, with some of them being much more easily broken than others; fortunately this is merely an inconvenience, and they're easily glued back together. 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 Face–Heel Turn.

Their electromagnetic senses and communications give them an instinctive understanding of technology, and they can gain mobility and additional senses by allowing themselves to be implanted within droid bodies.

These were poached by ancient Shuriman and Piltovan thieves, the latter of whom realized they were incredible power sources and used them as the gateway towards the development of hextech and the global industrial presence of Piltover.
