Does Thor have any weaknesses

Answer 1

In some Marvel Comics stories about Thor, if he is out of contact with his hammer, Mjölnir, for more than 60 seconds, he reverts to being an ordinary human. He has to touch his hammer again to regain his powers.

Answer 2

One weakness of Thor is that he can have his powers diminished or even be temporarily incapacitated if separated from his enchanted hammer, Mjolnir. Additionally, like other Asgardians, he is susceptible to certain types of magic and may have vulnerabilities to certain types of attacks or weapons.
