"A subject infected with the Nerotonin Type 4 (N4) virus. The Volatile Leaper is a creature that is encountered in rare occasions within the Wastelands of the inner city. Very few alive can tell the tale of even seeing one.

It is an evolution of the Leaper variant, where the subject's skin thickens to a leathery type of material similar to kevlar and the subject's tongue is freakishly elongated into a hardened weapon that is comparable to titanium. The Volatile Leaper is a charred skin, gigantic version of it's predecessor with its features multiplied in strength. It is also one of the fastest known creatures to lurk within Fairview.

Attacking one in melee range is widely considered to be suicide due to the nature of a Leaper's tongue."
