10 Things Everyone Always Gets Wrong About Thor
2. His Hammer Has All His Powers
All Odinson/Thor head-scratching aside, it's also worth remembering that Thor's powers aren't exclusively because of Mjolnir.
As an Asguardian, Thor is basically immortal, as well as having a healthy dose of super strength and endurance, which definitely doesn't hurt his chances at being a superhero.
Moreover, Thor also has practically a treasure trove of other magical devices to help him out that he's acquired over the years. Between the Belt of Strength - which really just does what it says on the tin - and his chariot drawn by two magical goats, which serves to give him basically the same sweet travel powers that Mjolnir does.
So yes, Mjolnir is where the majority of Thor's rad powers reside. But it isn't the only way Thor has powers, which is important to remember with the amount the hammer ends up missing or broken.
