Thor is a super strong and powerful god from the myths of the Vikings, who lived a long time ago in northern Europe. He was said to be the god of thunder, lightning, and storms.
Imagine you're playing outside and suddenly there's a big BOOM in the sky and bright light flashes all around you. This is what Thor would create with his hammer! His hammer is called Mjolnir (that's a big name for a hammer!), and it's so strong that it can break almost anything.
Thor is also a really brave fighter, and he helps protect his people from bad creatures in the world. He's always ready to go on adventures and face challenges, just like a superhero.
If you ever see a picture of Thor, you might notice that he's very muscular and has a big red beard. He wears a special outfit that helps him fight, with a red cape and silver armor.
Overall, Thor is a character from old stories who represents bravery, strength, and protection. It's really cool to learn about him and his adventures!
