This definitely deserves more reviews.

You must have done some reading into Norse mythology to know about Magni

Please continue.

this was fun and cool, its a good idea but be sure to not write yourself into a corner, what makes an even is purpose and reason, and a solid story, this is great so far but if you are taking marvel into the future you have to keep up with the timeline, so magni(cool name btw) wont be facing most of the things thor faced

Wow its a really good story! I love that movie. I liked your beginning. Can't wait to read more!
