3. Mjolnir can control the weather
Thor can easily control the natural phenomenon and elements like water, land, air, ice, thunder and other natural processes. He can swing the hammer to create storms, hurricanes, blizzards, earthquakes, volcanos and many other. As he can create these elements, he can slow stop them with a single flick. He can manipulate all kinds of energies.
4. The God Blast
With the help of his mystical links with Mjolnir, he can channel different forms of energies and muster them into a single massive energy blast, which can even kill the immortal in a single smack. And the god blast is so massive and immensely powerful that it caused a serious damage to Galactus and he fled after that to save his life.
