A diplomat who can turn invisible and put a wall of force between two things, and who is the reason her world is at peace.
Sue Storm is the most powerful member of the team and, unusually, the film says so. Her force fields are the only thing on the board that can hold, and her diplomacy is presented as the reason her Earth has largely disarmed, which puts the negotiation at the centre of the story rather than the fight.
Vanessa Kirby plays her as someone who has been the adult in every room for years and is tired of it in a way she will not discuss.

These four live on Earth-828, not on the Earth the rest of the Marvel Studios run takes place on. That was decided before the film was written, so that a team this capable would not need an excuse for having been absent from everything else.
