Great start with an extensive prologue and good setting, but mediocre continuation at best.
I liked how his powers were explained and how the author meshed everything together, but apart from that, I'm a bit disappointed.
I wanted to write a longer review, but I accidentaly closed the window and I won't bother rewriting it.
Basically, if you are looking for an OP MC, you are not looking for this fanfiction. Fast paced start and quite AU, with HP world mattering little. Neither should you read this if you are looking for a nice gamer fic with level ups and all, since this is not part of this fic.
There is plenty that I liked, but even more that I disliked. From characters to the way the author writes to the world s/he wrote.
The magic system is pretty neat, though I have no idea whether this is just using the marvel comics system or not.
Over-all, the author is articulate and the text is of good quality, but there a plenty of points that go ignored in favour of unnecessary or boring parts.
Oh, and this is not a Harry Potter fanfiction. This is a marvel fanfiction with the wizarding world being pretty much unimportant after the stretched prologue.
