First off, I would like to point out that, although I love superhero movies, and have read a few superhero comics, I've never read a superhero novel. As such, I'm not entirely familiar with the style of the genre. Keep that in mind when reading my comments.
Overall, I liked it. I like superheroes. I think they're awesome. Simply having them in your story already earns it some cool points. I thought the characters, their backgrounds, and their powers were well thought out, and pretty cool.
However, I felt that it was a little hard to believe that the character was able to make the connection that Nobel was both Blaster and his father. With the evidence given, I never would have come close to guessing either. I think it is just fine that he makes those connections in the first chapter, but I think it would need more obvious clues than were given.
Another part that bothered me was Nobel's narration of what happened to Blaster. While, by the end, it is understandable why he would be able to know so many details about the event, the way he tells it doesn't seem believable. Even if he was there, and knew the details of the event vividly, would he tell it like that? It felt too much like you were just narrating the scene normally, than actually having Nobel relate the story.
Despite those setbacks, however, I liked it, and think it has a lot of potential. Superheroes are awesome.
