Ant-Man And The Wasp Trailer - 10 Major Plot Reveals
4. Ghost Wants Revenge And The Tech
Speaking of Ghost, here we get out first look at the new villain - played by Hannah John-Kamen - before a proper look a little later on in the trailer.
Although the gender has changed, the rest of the character looks to be in keeping with how they appear in the comics: there he created a microchip that gave him a connection to computers, allowing him to not only become an incredible hacker, but making him intangible and allowing him to phase through walls.
As a hacker, it could well be that the character is motivated by revenge for Lang's whistleblowing, although the origins we're glimpsing here - and the way she's seemingly chasing them - does fit with the suggestion of her wanting the sub-atomic tech, either for herself or at the behest of her creator (which, as discussed, is possibly Bill Foster). Indeed, as someone who targets large corporations, she might be sent to spy on and steal from Pym in this movie, which is why he takes the building with him (Goggins' Sonny Burch could also be involved here).
It also looks like Ghost's suit, at least in these early stages, is glitching, which might at least in part be why she's taken the job on.
