Overlords

The Overlords take a planets fiercest creatures and mutate them sometimes beyond what the host bodies can withstand. These mutations are made possible by a naturally occurring “green ooze” on their home planet. It is common for young and ambitious Overlords to venture into space seeking the most terrible creatures with which to mutate into future champions of the arena.
Every now and then an Overlord will find a relatively stable mutation and will breed these new creatures to serve as a personal army. As much for prestige as for any real personal protection. On the table the Overlords are a powerful force of mutation and chaos. They have a high distribution of the Adrenaline super ability which can increase their combat ability or even resurrect them from the dead.
