I hope we see her again, whether it's in Ant-Man 3 or a possible Thunderbolts.

She was left in limbo by the snap, Ant man was in the quantum zone to help her when , hank, hope and Janet turned to dust and obviously when king rat freed Scott in Endgame reappeared but Ghost would of been left in devastating pain unless she was also bliped out of exsistance, in which case now she is also back is once again , well still in great pain. Ant man 3 must show how this is resolved. Also there has been deleted scenes found showing Janet and hank were there when ghost was experimented on and not only know why she is suffering but partly responsible.

Ghost was not a bad character. Her skills are sick, even though she considers them a disease. And I feel bad for her. But now that she's been helped out, I wonder when she'll show up next time. Maybe she could join the new team of Avengers or something. I also wonder if she survived when Thanos snapped his fingers with the Infinity Stones.
