He was an ordinary werehog with a wolf tail until war broke out in his homeland. Since he was male he was dragged in. The doctors knew that were animals were much stronger. So they got some scientists to make a way to keep the soldiers in were form during the day for when in battle. They made a syrup of such a drug and tested it on Streakshot before giving it to other soldiers. Sadly the effects were permanent. Making it impossible to go into towns since were animals will be killed in there. So he had to strive through the woods. Which isn't a huge problem since instincts are quiet sharper in his were form. Having a eternal hatred for war, scientists, doctors, and dentists. He doesn't like anyone screwing with his genetics, body, and teeth. In fact when he tried going to the dentist disguised as a wolf citizen, the dentist thought it would be fun to get a fang from and tried to pull one out (Streakshot's teeth were healthy). So when the dentist pulled on one of his fangs Streakshot just kind of had a little snack. Yeeeeah don't send him to a dentist. He met up with Gazer one night when chasing a lonely deer.
