The Marvel Cinematic Universe is getting bigger all the time, with Ant-Man and the Wasp adding several new heroes and villains to the mix. One of those new additions is Ghost (played by Hannah John-Kamen), a sinister villain who — in the comics anyway — lives to make life miserable for the business tycoons of the Marvel U.
If you’re not familiar with Ghost, here’s everything you need to know about the villain and his/her comic book background.
Where most Marvel villains are busy trying to take over the world or feuding with their superhero nemesis of choice, Ghost is more motivated by a love of anarchy and a desire to punish oppressive corporations. Ghost has dedicated himself (more on the character’s gender in a sec!) to attacking the largest corporate empires in the Marvel Universe, using a combination of elite hacking skills and phasing abilities to dismantle them from the inside out. Sometimes he works as a hired mercenary performing acts of corporate espionage. Other times he chooses his own targets. But either way, Ghost is a real thorn in the side of powerful businessmen in general and Tony Stark in particular.
