These creatures are only found in swarms. In their structure they resemble ants, but they are unified in a common mind, enabling them to crawl over each other and by sheer numbers assume the form of various other Pokemon and administer different physical attacks. Their versatility enables the Nyhts to be highly valued among trainers. They are almost as adept at assuming other forms as the shape-changing Ditto, but while Ditto can also copy an opponent’s form and abilities, the Nyhts may only use physical attacks.
I love this one. It harkens back to the idea of Pokemon being in groups to form a single entity, such as Dugtrio, and more recently Klink, just as a couple obvious examples. Notice the phrase (unified in a common mind), which explains its evolution (which I don't like as much but will post for the sake of completion of the line).
