Monica Rappaccini

While Luke Cage may be seen as one of the weaker Marvel and Netflix collaborations, it does have its merits. One of them is that it reintroduces Hammer Industries in the MCU, after Iron Man 2’s events saw the CEO arrested.

In the same way, after Iron Man 3, we haven’t heard anything about AIM. So maybe The Defenders presents the right opportunity for the organization to make a comeback. After Killain’s defeat, someone else must take over. And that someone else could be Monica Rappaccini, also called the Supreme Scientist.

This character would be a good fit for Sigourney Weaver, since it wouldn’t be a physically demanding role. Even in the comics, the character relies on devices and various substances, and not on physical attributes.

Given her expertise, Monica Rappaccini could be adapted for the show. In this way, instead of being from AIM, she could be the head of IGH. As the face of the company, the character would benefit from Weaver’s charisma.
