Sorren here is a member of a resurrected bread of dinosaur. In the future humans retro engineer dinos from the DNA of there Bird decedents. Some of them were accelerated through an alternate evolutionary path to produce the Saurians like Sorren here. Humanity used the Retro Engineering to bring back all sorts of extinct animals. Even Neanderthals were brought back to life. However the Neanderthals were brought back for the purpose of slave labor as the Saurians were now doing as well. Saurians were used for there resistants to radiation as well as toxins and Neanderthals for there superior endurance. The two species however banded together and started a rebellion against humanity. Sorren here is a general in the Rebellion Army with not love for humans.
