Thor: Tales of Asgard/少年雷神

The animation is about the story when Thor was still young and be hungry to prove himself a worth warrior. To complete this proof, Thor actually did not need to find the Sword of Surtur in Yodenheim, but to protect Asgard from war and enemies inside.

The story paced very fast understandably; it had to tell the complete story in less than 80 minutes. Well, it did a fairly good job.

And it was an interesting contrast between Odin and Thor: both of them finally found enemies who had been their intimates: Algrim to Odin and Loki to Thor.
