Mutant Killer

5 years ago, a group of scientists worked in a corporation called B.A.G.C or Bio Alien Genetics Center. Trying to take the D.N.A from an unknown humanoid, trying to make a cure for any cancer. They leave the lab to go home and come back the next day. They all find that the humanoid was gone and they see that it had escaped through the windows. Later that day, the news reported that a strange green man has been attacking homes and have been hiding in closets. The government soon found out that the lab group had done this and they were all charged for illegal experiment projects but a few years of jail for a bunch of lab people wasn't stoping this thing.
