Ant-Man And The Wasp Trailer - 10 Major Plot Reveals
5. Bill Foster Probably Creates Ghost
Laurence Fishburne's Bill Foster is one of the main newcomers for the sequel, and though he just appears in the one shot there's enough to make a lasting impression.
In the comics, Foster is a great scientist who works with Pym on his technology, and later becomes a hero in his own right known as Black Goliath. That could well be the case here, but the editing of the trailer is designed to leave us with a different idea.
The shot of him in a lab follows the one of Ghost's apparent origin, with the suggestion that he's the one responsible for creating the Ghost tech, and is going to be a villain and more of a rival to Pym. That would be treading a similar path to Yellowjacket in the first movie, but they can differentiate thanks to the Ghost and the exploration of the Quantum Realm, with the sub-atomic tech likely to be the real target.
