One of the most significant contributions that WandaVision has made to the Marvel Cinematic Universe is the establishment of S.W.O.R.D. – the Sentient Weapon Observation Response Division that was founded by Monica Rambeau’s mother Maria Rambeau.
In the comics, Brand is actually the commanding officer of the intelligence agency, and while she doesn’t actually have a scientist background, that’s something that one could see this version of the canon change to better suit the story that’s being told in the Disney+ series (especially given that S.W.O.R.D. apparently doesn’t have a permanent leader in place in the wake of Avengers: Endgame.
We’ve met some key players thus far (including Acting Director Tyler Hayward), and the end credits of Spider-Man: Far From Home have suggested that both Nick Fury and Talos are involved in the organization, but one particular name not yet brought up is Abigail Brand.
