The Uroboros Test Subject is an experimental B.O.W. and the first boss of Resident Evil 5. This creature was created by injecting a resident of Kijuju with the Uroboros virus and then setting it loose in the shanty town. It entered an abandoned apartment building where it attacked and killed an entire BSAA commando team. Wherever it went, it would leave copious amounts of black ooze in its wake. Chris Redfield and Sheva Alomar were cornered by the creature inside an incinerator facility where they found that their guns had little to no effect on it. Luckily, the monster proved to be very vulnerable to fire as the pair discovered after trapping it in the incinerator, which quickly destroyed it.
