Every MCU Avenger Ranked From Weakest To Strongest
4. Thor
When Thor first came to Earth, he was a demigod from another planet, with a magic hammer that no one else was able to lift, and could summon lightning from the sky. He was nothing like the world had ever seen before, and yet he still wasn't considered to be the strongest Avenger.
The Hulk was recognised by the Avengers quinjet as the strongest Avenger, but Thor has grown a lot since Avengers Assemble, and even Age of Ultron, both in terms of maturity, and strength. Without having Mjolnir to rely on, he was able to defeat Banner in the Grandmaster's arena, and learnt to truly harness the power of thunder and lightning as his title would suggest.
No one else in the universe would have had the physical strength required to hold open the mechanism of Nidavellir while taking the full force of a star, and he now has the impressive Stormbreaker in his arsenal.
The God of Thunder has grown immensely stronger throughout his time in the MCU, and has even managed to find an upgrade to Mjolnir. With the Thanos killing weapon in hand, there's not many that could face up to Thor and come out on top.
