Could it be...
Fury's heart sank slightly.
"What we know about Asgard comes from mythology. In our myths, Loki is supposed to be Odin's brother—your uncle!"
Fury shook his head and sighed inwardly. The details were wrong. Completely wrong. Everything was a mess. Chakra, the Warp, magic, psychic powers—these forces from works of fiction all matched their respective settings. Every jutsu from Naruto could be used, even if most people had too little chakra to use them. Likewise, all the magic from Harry Potter could be used.

Suddenly, Fury thought of a possibility: Thor wasn't the Thor from mythology, but one from a work of fan fiction. It was entirely possible. The chakra that had appeared on Earth was also fan fiction, in a way. Originally, it was a concept for a kind of energy from India.
But after appearing in reality, the rules governing this supernatural power had followed Naruto's setting completely. It had almost nothing to do with the Indian concept beyond sharing a similar name. It was like one person being named Spot, and a dog being named Spot too.
