"I was partners with Hank on a project called G.O.L.I.A.T.H.."
―Bill Foster[src]

William Barrett "Bill" Foster is a biochemist and Berkeley professor who previously worked with Hank Pym on Project G.O.L.I.A.T.H..


Early Life

Project G.O.L.I.A.T.H

He worked with Hank Pym on Project G.O.L.I.A.T.H.. During the project, Bill was able to grow to at least 21 ft.[1]

Meeting Ava Starr

He met Ava Starr when she was a child. He became her surrogate father after the death of Elihas Starr and vowed to help find a cure for her condition. Despite his protection, he wasn't able to prevent S.H.I.E.L.D. from running tests on her and turning her into a killing machine.[1]

Stealing Pym's Portable Lab

He showed up at Ghost's lair after she'd restrained Scott, Hope, and Hank. He revealed to them the reason why he was helping Ava and how they needed Janet van Dyne's quantum energy to cure her. After their escape, Ghost threatened to kidnap Cassie Lang and use her as ransom in exchange for the lab. Bill threatened to walk away from the whole situation if she did that.[1]


Bill is an exceptional and intelligent scientist on par with Hank Pym enough for the latter to consider him his rival. He however resented Hank for his ego and trying to fire him. He hated Hank, as shown when he helped Ghost with her plans and showed concern for her. He also treated Ava like his own daughter and refused to leave her side when asked to and also tried to reason with her when her plans went to extreme, hinting that he had morals.
