Ashlocke

The psychopath New Mutant Gabriel Ashlocke was the first and most powerful Child Of Genomex created. He is also known as Patient Zero and possessed abilities of all four New Mutant Types: Feral Feline, Molecular Intangible/Force Fields, Elemental Electrical and Psionic Telepath/Telekinetic.
He was born without a conscience so little Gabriel's aggressive tendencies quickly spiraled out of control. On October 13th 1978, Gabriel's parents brought the 10-year-old Gabriel back to Genomex so that Adam Kane could make him more human by reducing his abilities. But Adam had unfortunately overlooked a weakness in strand 19 Gabriel's DNA, and his treatment only caused further fragmenting in Gabriel's genetic structure. Gabriel murdered his parents six months later. 
In order to protect the world from his malignant potential, Adam and Mason Eckhart placed Gabriel in a stasis pod where he remained in a coma-like state for 25 years until he was released by former GS Agent Morgan Fortier. He and his group of loyal New Mutants, The Links, formed an organization bent on world domination called The Strand. With the aid of Dr. Kenneth Harrison, Gabriel placed Mason in a stasis pod and took over Genomex headquarters. He then turned his vengeance sights upon Adam and Mutant X, while searching in vain for methods of stabilizing his DNA. Once he got inside Sanctuary with his ally Kim thanks to his Telepathic union with Shalimar, he tried to force Adam to cure him. His dramatic cellular breakdown quickly led to his explosive death, but not before he had impregnated one of The Links, Kim. Prior to his death, he set into motion the eventual creation of his successor, The Child, using genetic samples from one New Mutant of each type.
