Dark Tigers are a race of dark-colored, evil tiger with glowing cyan eyes. Males are 2 meters (6 feet) long. They were created on Aef, so you could say they are native to that planet.
They are born with powers of Darkness, and are able to use it for evil. Their claws can shoot destructive blasts of darkness, and their eyes can each shoot a sphere of darkness that explode when they touch something.
