As the thirty-year War on Mutants drew to an end, four mutants remained alive: Chamber, Jubilee, Leech, and Skin. While they survived, the makers of the Sentinels overlooked them simply because they did not see them as a threat. Unfortunately, for the Sentinel makers, the last family of mutants had Leech on their side and Leech had grown up during the War. Leech could now use his mutant abilities to hide the DNA of the family so that could infiltrate Operation: Mutant Armageddon and bring it down.[1]
