Korath Thak the Pursuer

Courtesy of Marvel.com:
Korath-Thak is a brilliant cyber-geneticist who was one of the creators of the Pursuer project, creating an energy template that could transform any matter it touched into a form it could use to pursue and subdue its intended targets. The first use of the template was at the instigation of the Kree science council to bring the Inhumans of Earth to Hala to serve as conscripts in the Kree army. This action would insight the conflict that has come to be known as the "War of Three Galaxies." The template was beamed to Earth but instead of hitting stones or metal as hoped, it hit and transformed cockroaches. In this form the Pursuer defeated the Inhumans Royal family; (Black Bolt, Medusa, Gorgon, Karnak, and Triton) until the Kree defector Falzon used an insecticide to stop the template.
