Ninja Blade

It was July 7th, 2011. While investigating reports of unlawful weapons trafficking, peacekeeping forces encountered an unclassified carnivorous species occupying a small village in Northern Africa. These rabid creatures were easily provoked and resistant to conventional attack. Eight specimens were encountered in the region now referred to as "Ground:ALPHA"... Only four were successfully contained for study. Victims of the attack were quarantined at a research facility nearby. These victims displayed signs of internal liquefaction and accelerated necrosis, similar to symptoms of other flesh-eating viruses native to that region.
