Scorpion Type Y-139
This was an early experiment utilising the T-virus on insects. As with most creatures that are relatively low down the evolutionary ladder, no major mutations occurred and the test subject simply increased in size and strength. This BOW was sighted in Raccoon Forest and was reportedly killed by STARS members. Like all poisonous creatures infected with the T-virus it features overdeveloped poison sacs. Parts of its shell have hardened into a tough exoskeleton that is capable of deflecting bullets. Problematically the sudden development of its shell has resulted in corresponding fragility, causing some areas to become exceedingly weak. This includes the head carapace making the Y139 an impractical weapon. No further research was carried out.
