Phalanx

The entity called Harvest was once a human man with a loving family, and successful career. He willingly tossed that all away when he allowed himself to be wholly assimilated into the Phalanx, a techno-organic species determined to rid the world of mutants. An evolving life form, the Phalanx is capable of adapting to mutant powers, and can't be beaten the same way twice! Intent on preserving humanity, its directive is simple: absorb those who oppose, destroy those who cannot be absorbed!
