Ghost

Ghost is a Marvel Comics supervillain equipped with the ability to phase and become intangible, sometimes functioning as a mercenary.

Avengers Assemble
Ghost was a enemy of Iron Man's who had fought him several times in the past. However, after one of Ultron's failed schemes to destroy the world resulted in Terrigen Mists being released throughout the world, causing people with dormant Inhuman genes to undergo Terrigenesis and become Inhumans. It turned out that Morley was one of those many people, and upon emerging from the Terrigen cocoon, found that he had obtained actual phasing powers, no longer needing to do so with his tech.

In "The Kids are Alright", Ghost hatches a scheme to steal F.R.I.D.A.Y. and sink Avengers Tower. He did so by hacking into the tower's systems and tasing Falcon and Hawkeye.
