While Captain Marvel gave audiences a glimpse of Danvers' power, Avengers: Endgame (2019) showed why she hadn't been involved as a character in previous films: she would have defeated the enemy very quickly. Danvers gained her powers after being exposed to the raw energy of the Tesseract.
The God of Thunder has always been known to be one of the strongest characters in the MCU. His Asgardian physiology alone grants him abilities beyond those of any super soldier, let alone regular humans. His godly power makes him a formidable ally to Earth's Mightiest Heroes.

In Thor: Love and Thunder (2022), he gets a peek at Eternity, a force so powerful that it is capable of granting any wish regardless of what it might be. Thankfully, Eternity is so all-powerful that it doesn’t seem to have much time to worry about the affairs of the mortals.
