Kevin Feige has said in an interview about Captain Marvel in the MCU:
With Captain Marvel, she is as powerful a character as we’ve ever put in a movie. Her powers are off the charts, and when she’s introduced, she will be by far the strongest character we’ve ever had.
To me that reads as not only being physically strong (like Hulk or Thor) but more powerful in a broader sense. And we have characters like Scarlet Witch, Dr. Strange and Thanos to compare her to (who are very powerful in a more magical/mystical/metaphysical sense).
Is there a basis for her being the most powerful character from the comics?
