Unown
Psychic
Generless
Individually, they are among the weakest Pokémon. The reason these things are Hazard Class Restricted is that they are some of the deadliest Pokémon in groups, and are never found in populations smaller than a thousand.
Description
The Unown all share two characteristics. They have black bodies. Those black bodies protrude from a large, unblinking white eye with a small pupil. They are flat and are usually found plastered to a wall in their slumbering state or their passive state. There are at least twenty-eight different forms of these alphabet Pokémon. The Unown all Levitate constantly when active.
Battle Characteristics
The only move they learn at all is Hidden Power. They have moderate Strength and Power with weak stats everywhere else.
Legends/Folklore
It is believed that every alphabet in the world was in some way derived from the hundreds of Unown forms.
Unown can write dreams into reality.
Extremely powerful spell casters can command a small number of Unown, around a hundred, and cast spells with them. These spells are not as potent as what thousands of Unown can do when gathered.
Unown primarily appear in certain ancient ruins. The purpose the ruins once served is unknown. Researchers that enter these places are known to disappear. Pokémon avoid these places, and even the strongest will react with fear if brought to one. The fear gets supplanted with curiosity after a while, and the Pokémon start searching for something or reacting to things that are not their. Strange radio signals can be detected when in the areas.
Life Cycle/Evolution Conditions
They do not age.
Diet
They do not eat.
Breeding
They do not breed.
Wild Behavior/Threat Level
They are as dangerous as the task they are set to perform. If they guard a location, entering it could result in instant death, being banished to another world, or any number of other fates.
Bonding and Care
They have no emotions and cannot be bonded with.
Human/Pokémon Relations
Dangerous. They either have their goals and tasks, in which case they will write a human away, or they have no goal, in which case they will cause random thoughts to become reality.
With Family
Will not react or interact with family.
Team Compatibility
Unless the whole team is Unown, they are largely worthless and will not work with or against a team.
Warning
This cannot be understated. Unown cause the words they spell to manifest, and there is no telling if they are spelling something dangerous until it is too late.
Summary
An alphabet that writes reality.
