Thor himself, freshly equipped with his new god-killing hammer, StormBreaker, is also no slouch. Wielding the power of thunder, Thor can teleport through space and nearly take down a fully powered Thanos.
Doctor Strange is also a significant contender, able to see into the future and change the past, his magic is capable of taming even the most powerful beings like the inter-dimensional destroyer of worlds, Dormammu.
There is even speculation that the MCU could move onto a much bigger threat, in the shape of Galactus.
In the comics, Galactus is capable of eating entire planets, making him one of the most powerful beings in the entire universe, but he is yet to be even hinted at in the MCU.
Captain Marvel, however, is capable of much more, given her secret weapon.
Fans speculate that Captain Marvel will wield a secret seventh stone, that holds all the power of the previous six in one.
