Marvel Cinematic Universe gave its fans their first taste of Captain Marvel during the post-credits scene at the end of 'Avengers: Infinity War'.
In the scene, Nick Fury (Samuel L Jackson) sends out a distress signal from a modified pager before being 'snapped' along with a few of the beloved Avengers and half of the universe. Captain Marvel aka Carol Danvers, played by Brie Larson, shows up in the scene as Bruce Banner (Mark Ruffalo) and the team of surviving Avengers manage to get their hands on the pager and are trying to figure out how the contraption works.
For those who already know what Captain Marvel can do, her presence in the upcoming 'Avengers: Endgame' suggests that she is a force that can tip the scales towards the ones out to avenge the fallen.
The fact that producers Anthony Russo and Joseph Russo, collectively known as the Russo brothers, have introduced the character in the final installment of the Infinity Saga has fueled theories that she is the most powerful superhero in the MCU who will also pave the way forward.
According to wegotthiscovered, Marvel Studios President Kevin Feige explained that this superhero is the most powerful that the MCU has seen.
Many wonder why Fury waited so long to bring in Captain Marvel and why he didn't do so when the Avengers fought Loki along with the Chitauri army in New York or when they took on Ultron. Was the sheer force of the snap so incredulous that he decided to take the desperate measure of reaching out to her? Or was he so supremely confident that the fractured Avengers, post the Civil War, weren't ready to face a threat as a team and needed a binding force?
During his time with the Avengers, it's evident that Fury kept tabs on what each of them was up to. With the Sokovia accords splitting the team into two, it was clear that they were not ready to face a greater threat, let alone avenge it. This, despite all the fantastic qualities that the Avengers have shown over time.
While much of the superheroes were learning to master their powers, Danvers has an edge in that she is in full control of her abilities.
At the end of 'Captain Marvel', it is established that Danvers is inarguably the most powerful superhero when she single-handedly channels the energy from an infinity stone to destroy an entire Kree fleet.
Add to this a few meta-human abilities, enhanced strength, resistance to poisonous toxins, courtesy her mixed Kree/human DNA, her ability to time-travel, and a binary mode that she partially put to use, we have a virtually indestructible superhero.
If one thing is certain, it is that many of the leading Avengers will meet their end at the end of 'Avengers: Endgame'. Going by the fact that the current group aren't going to necessarily stick around, this would mean that the team will also need a new leader. Danvers' ability to not give up in the face of insurmountable odds along with her superpowers make her the perfect leader for the remaining Avengers.
For instance, she doesn't bat an eyelid when Thor tests her measure by summoning the Stormbreaker dangerously close to her face. Need we say more?
