The Nicky Haugh Resistance are perfect recreations of the original Nicky, retaining all of the original's physical and psionic abilities. They were specifically created to derive a strain of the t-Virus to reverse the ravenous effects of the original virus of humanity by increasing their intelligence.
In his research for a way to pacify the infected population swarming the globe, Nicky Haugh created a multitude of clones of himself. Using their blood, Nicky devised a serum that was supposed to increase the intelligence of human test subjects. However, while the serum did succeed in temporarily increasing the human's intelligence, it actually increased their ferocity and the strength of the infection.
