Character traits

Bill Foster is an exceptional and intelligent scientist rivalling Hank Pym. Foster is much nicer and more friendly than Henry, as evidenced by how he got along well with Scott Lang upon meeting him and commenting on his size-increasing trials in the old days. Although Foster resented Henry for what he saw as ego and arrogance, he did not extend this to Janet or Hope van Dyne, having been good friends with Janet and sadly recounting on how he tried to stop her from getting too close to Henry and failed that led to her doom and likewise being friendly with Hope, showing his lack of prejudice. He noted that he was willing to extract Janet's quantum energies because he thought it won't kill her and ultimately he worried for Janet when Ava drained her energies and tried to stop her. He was also a good friend of Elihas Starr, sympathizing with him over his desire for recognition after Hank fired him, even after what Elihas did, showing he is a loyal and reliable friend.

Foster deeply cares for Ava Starr, treating her like his own daughter, doing whatever he could to heal her of her condition. He tolerates several of her more ruthless actions, though he regretted the necessity of such acts and showed even his love for her has limits, as shown when Starr suggested kidnapping Lang's daughter, Foster vehemently rejected the idea, going so far as to say if she laid one finger on her, he would no longer help her, even though Scott had tricked and prevented Ava's restoration, showing that Foster puts his morals first and personal feelings second ultimately.

Foster showed that regardless of their bad past, he still cared for Hank and did not wish for him to die, as he defended him from Ava and was concerned when he was seemingly suffering a heart attack. They eventually achieved a reconciliation of sorts, as Foster came to trust that Hank would help in Ava's recovery after he had saved Janet.
