I know that right off the bat I’m going to get a lot of hate for this, but the thing is that I don’t really care. Captain Marvel has been an extremely controversial superhero partially because of the fact that she was stated to be the most powerful superhero by Kevin Fiege. There are other reasons for the ongoing conflict but this is one of the most prominent ones.
Many people have been outraged by the concept of her being this powerful, but the goes to show how little is known about her character. In the comics she is one of the most powerful of Earth’s superheroes but simply isn’t in the same level as people like Hulk and Thor, which makes the idea of her being the most powerful quite jarring. But her being more powerful than them can be explained by a character named Binary.
If you have not heard of Binary you are hardly to blame, her first appearance was over two decades ago. Binary is a form of Captain Marvel that was created by a species known as the Brood who abducted Carol Danvers and mutated her genes turning her into the cosmic being. While she doesn’t have many feats, it has been stated that Binary is a being with the power out out of an exploding star. In other words, a walking supernova.
If this is what happens in Captain Marvel or Avengers: Endgame then that would explain why she is will he so powerful. After all, another famous Marvel character nearly died when facing the power of nothing but neutron star. Regardless of how you feel about the character of her place in the MCU, the writers and directors know what they are doing and should be given the chance to make a good movie before being judged.
