If you’re a fan of comic books, superhero movies, and the Marvel Cinematic Universe, this past weekend was like Christmas, Halloween, the 4th of July, and the Super Bowl all rolled into one. The San Diego Comic Con is essentially the epicenter of geek culture. In recent years, it has only gotten bigger, becoming a staging area for major pop culture events. This latest convention was no exception.

While there was plenty of news to follow at this year’s Comic Con, especially for X-Men fans like me, the biggest event was always going to be Marvel Studios. It has already been a historic year for superhero movies, especially on the Marvel side of the genre. Shortly before the convention began, “Avengers Endgame” officially passed “Avatar” to become the highest grossing movie of all time.

It’s a good time to be Kevin Feige.

It’s a good time to be Bob Iger.

It’s a good time to be a Marvel fan, in general.

With the end of “Avengers Endgame,” however, the story that began in 2008 “Iron Man” has concluded. The Avengers assembled in a truly spectacular battle for the ages. Thanos is defeated. The Marvel Cinematic Universe is once again secure, but after making the highest grossing movie of all time, how can Marvel Studios keep raising the bar like this?

In Hall H of the San Diego Convention Center, the next phase of the MCU was finally revealed. Some of the announcements were expected. News of a “Black Widow” movie, as well as an “Eternals” movie, had already been reported months ago. News of a “Blade” movie within the MCU was more surprising, but that wasn’t the biggest story by a long shot.

By far, the biggest Marvel Studios news to come out of San Diego Comic Con 2019 was Natalie Portman returning as Jane Foster to play a female Thor. I’m not going to lie. When I saw this news, I had to blink a few times and slap myself to make sure I wasn’t dreaming. Once certain this was real, it finally sunk in.

Natalie Portman is returning the MCU as Jane Foster to play a female Thor.

To appreciate why this is a huge deal to longtime comic readers like me, I need to provide a little context. Jane Foster being Thor is a concept that only recently gained prominence, thanks to one of Marvel’s top-tier writers, Jason Aaron.

Back in 2014, the Thor comics underwent a major upheaval. After a fateful encounter with Nick Fury, Thor suddenly became unworthy of lifting Mjolnir. It was a dramatic moment that defined the character for years to come. Then, after everyone in Asgard failed to lift the hammer, Jane Foster came along to wield it. In doing so, she became the new Thor.

If you haven’t read the first few volumes of that story, I cannot recommend them highly enough. Even if you’ve only seen the movies, you’ll still find plenty to love about these comics. They made me a fan of both Thor and Jane Foster. If Marvel Studios and Natalie Portman can even capture a fraction of this story’s greatness, then it’ll be a bold new era for superhero movies.

Now, make no mistake. Jane Foster becoming Thor was not without controversy. In fact, the timing of this story couldn’t have been worse. It came out right around the same time that efforts to promote diversity within superhero comics had become mired in regressive politics. It was a time when iconic characters were being replaced and new characters were being created, albeit with mixed results.

I’d rather not go into all the issues, controversies, and absurdities from that era, but I will say that Jane Foster becoming Thor was one of the success stories from that tenuous period. Her journey as the new Thor didn’t supplant that of her predecessor. If anything, it complemented his story. The title of Thor was greatly improved because Jane Foster wielded that hammer.

Now, Marvel Studios is in an even better position to do the same. The success of both “Wonder Woman” and “Captain Marvel” has established that there is a market for female superheroes. The events of “Avengers Endgame” also opened the door for someone else to step in without diminishing Chris Hemsworth’s character, who may still have a part to play in “Guardians of the Galaxy 3.”

It also helps that Natalie Portman’s Jane Foster has been MIA since the events of “Thor: The Dark World.” While her reasons for leaving were somewhat obscure, the announcement at San Diego left no room for ambiguity. She’s coming back and she’s going to play a major role in the next phase of the MCU.

In my opinion, this will go down as one of the most pivotal announcements in the history of the MCU. Why do I believe this is bigger than the Eternals, Blade, Black Widow, or any of the upcoming shows on the Disney+ streaming service? To answer that, it’s necessary to take a step back and look at the bigger picture.

The Jane Foster that Natalie Portman played in the first two Thor movies is not the same Jane Foster who has established herself as a prominent force in the comics. Throughout her history, she has maintained a strong connection to Thor and not just as a romantic interest. In many respects, she has been the character through which ordinary, non-Asgardian people explore Thor’s world of gods, demigods, and monsters.

A big part of what made Jason Aaron’s story surrounding Jane Foster becoming Thor so powerful was how she proved her worthiness of that title. As a mortal woman with many mortal limitations, she embraced that role and proved herself against gods, monsters, and even other superheroes. It was easy to cheer her on every step of the way.

In any era, it’s a powerful story, having an ordinary human embrace god-like power to bear god-like burdens. In this current era of superhero movies, Jane Foster becoming Thor isn’t just a fitting, comics-accurate way to build her story in the MCU. It’s a story that almost feels necessary.

The MCU is a world that has become densely populated by super soldiers, aliens, gods, monsters, and demigods. With the conclusion of “Avengers Endgame,” the world is in a tenuous state. Friendships, families, and teams have been decimated due to the conflict surrounding Thanos and the Infinity Stones. There are voids to be filled, including a few once populated by gods.

Ordinary people becoming heroes is a story that the MCU has told many times before, the latest being “Spider-Man: Far From Home.” Stories about ordinary people becoming gods haven’t been nearly as common and with the Eternals already poised to join the MCU, I think that story should play out in some manner, if only to keep humanity connected to this world.

Jane becoming the Goddess of Thunder is the perfect story to maintain that connection. Unlike Carol Danvers, Jane is not a soldier or a warrior. She’s a scientist who got caught up in the world of gods and superheroes, but she didn’t run from it in the comic. Now, armed with Natalie Portman’s Oscar-winning talent, she’s poised to make a similar journey in a world that needs new heroes to step up.

It’s an exciting, but uncertain time for the MCU. However, when you’ve got a story like that of Jane Foster becoming Thor and an actress as talented as Natalie Portman leading the way, the future has never been brighter.
