Werewolves

Werewolves were engineered on the planet Auul to help its people fight off  invading forces from the neighboring planet Mraar. An artificial microscopic programmable virus called ossai was used to rewrite the genetic code of living organisms. The ossai made the subjects stronger and faster and turned their offspring into werewolves.

After the people of Mraar created their own superfighters in the form of werecats (also known as the Sun Horde), the people of Auul created a second generation of werewolves that were more powerful but less stable, called alpha-strain werewolves.
