Shadow Pokémon

Shadow Pokémon are Pokémon infected with Shadow Energy, turning them into monsters and murderers, and serve as one of the main antagonist groups of Stray. They are loosely based on creatures of the same name from the video games Pokémon Colosseum and Pokémon XD: Gale of Darkness.

Creation
N/A

Behavior
After the transformation to a Shadow Pokémon, the victim loses his/her free will and wanders aimlessly to target innocent travellers. Shadow Pokémon will generally attack anyone on sight, killing the target and occasionally feasting on the remains. Most Shadow Pokémon are incapable of speaking in complete sentences, while few can speak coherently.

Abilities
In addition to its standard attacks and abilities, a Shadow Pokémon may use Shadow-based moves that are very harmful to any Pokémon that is not infected with Shadow Energy. Depending on the strain of Shadow Pokémon, it will acquire exclusive abilities, such as manipulation of an unusual element or telepathy.
