Before the release of Thor 3: Twilight of the Gods, Muir's Hammer was always set as the source of Thor's power. With the hammer, Sol will become Thor and the most powerful warrior in the Nine Worlds.

But the movie Thor 3: Twilight of the Gods subverts this background. Odin once said to Thor: The hammer is used to help you control and concentrate your strength, not the source of your strength.

Recently, an online fan named u/brownpanther_333 put forward a more extreme theory. He thinks Muir hammer may even be a weapon to suppress the power of Thor.

Let's look at this netizen's theory.

The Reddit user believes that when Odin asked the dwarves to make Muir hammers, he essentially wanted them to make an "energy attenuator disguised as a weapon".

Odin's eldest daughter Hella once got rid of his control and tried to conquer the whole universe by force. In order to prevent Saul, the youngest son, from repeating his sister's mistakes, Odin had to control Saul's power.

This is also the reason why Raytheon 3: The Twilight of the Gods and Raytheon lost his hammer in Reunion 3-4, and his strength suddenly increased. He can finally release all his strength at will.

As for why Captain America used a hammer, he could compete with Thanos for a short time. The user explained:

The reason why Muir's hammer can give the power of Raytheon to those who can lift it is because of Saul.

Over the years, Muir's hammer has been quietly absorbing Saul's power and storing it in his body, which is why Captain America can split Thanos with a hammer.

Although this theory is a bit extreme, this special parenting style is in line with Odin's personal design. It is not excluded that Odin made this "child suppressor" to protect and guide Saul.
