These creatures are said to have come about as workers around the time of creation. They share a hive mind, with no single specimen possessing much of an ego. That and the fact that they can dissolve into raw power means they can fuse quite well into other creatures, permanently boosting their Atk power. Do not leave them unattended for too long, as they are known to dissolve those around them when left to their own devices.
