Greg was an technician who worked for scientist Hank Pym. He was assimilated by a shape-changing alien of the Chitauri race. Greg was working as a technician and assistant for brilliant scientist Hank Pym. Pym was working on developing a way to use ants to detect the Chitauri. It was probably while Greg was already working for Pym that he was killed and replaced by a Chitauri spy.

Of course, Hank Pym did not know that Greg had been replaced by a Chitauri. Presumably the original, real Greg had worked for Hank Pym for some time before being killed, devoured, assimilated and impersonated by a Chitauri spy.

Greg the Chitauri was present when Hank Pym first ran a test of his idea of using ants to detect Chitauri. The ants zeroed in on the Chitauri "Greg," which Hank thought was a mistake - until he realized that "Greg" was actually a Chitauri. Exposed, the Chitauri "Greg" dropped the pretense of pretending to be human and started to transform into his real form. "Greg" battled Hank Pym, but Pym killed him.
