It's a very good fanfic, the beginning wasn't the best, but with each chapter i feel the novel evolving, the system is "smooth", it's not unpleasant at all like most systems novels on this site, the MC's personality is relatively original, i feel like most of the MCs on this site are relatively similar so it's refreshing (to me) to read about a different mc, i hope that just like the story he will also evolve as a person.
His relationship with other characters hasn't been very developed yet, but it seems to be going down an interesting path, not too forced and not ignored, although there aren't many interactions yet i feel that everything is going in an ideal way, it's "smooth "...
I hope the author doesn't add more powers to the MC, i see some people complaining that he is weak and having the avatar powers is no big deal, but i believe that he can do amazing things with this power, especially if the level of power of the elements is greater than in Avatar (the anime), i imagine him being able to cause devastating earthquakes, summoning giant meteors (like madara), shooting lightning so powerful that Thor would be jealous, creating tsunamis of hundreds of meters, hurricanes so powerful that they can destroy entire cities, or even creating a new ice age!
Okay, i got a little excited here, but what I mean is that the possibilities are endless, his power is fantastic and it will be amazing to read about his development.
I love the DC universe, unfortunately there aren't so many fanfics about it and this is one that I'm most excited about it's future, i really hope that the author doesn't drop this novel, i'll be rooting for it.
