Ninja Blade

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.

But it wasn't a viral outbreak. It was a parasitic infestation. A previously unidentified species of hook worm was found beneath the skin of the Ground: ALPHA specimens. These parasites, we call them "Alpha-worms", laid dozens of eggs inside their hosts, which in turn produced numerous larvae. These larvae penetrated the bloodstream and triggered a variety of genetic failures. However, unlike most genetic failures, these symptoms were not fatal. Instead, infested victims were larger, stronger… and driven by hunger. Using the research gained from the Ground: ALPHA specimens, a team of some special individuals were assembled. Minor outbreaks occurred over the next few years, but elite squad quickly put them down. Which brings us to the current situation in Tokyo...
