A type of creature that can be found in Psyren. They generally resemble a large insect, or a human being. They can be recognized by the light-emitting sphere somewhere on their body, the stitch marks on various places (most visible on the limbs), the human-like arms and hands and their large power. They appear to be permanently hostile, attacking anything but their own kind on sight. Despite their strength, they are easy to defeat by destroying the light-emitting sphere. Doing so will cause them to die within a minute. Tavoo have evolved from looking more human to gross warped creatures and from weapon use to PSI abilities. Their size, mind strength, and purposes are endless.
What this means is Tavoo can range from virtually harmless, to incredibly deadly. They are also known to attack in groups, especially the smaller ones. Within the Tavoo size does not always equal power.
