Nico and the Avengers Fanfiction: Ultron is at large and has joined forces with the greek monsters and Hephaestus's newest inventions gone wrong. The Avengers need help, but aren't to thrilled with the bitter teen and his doctor that they are forced to work with. Nico di'Angelo didn't care less about the new super hero team until Hades assigns him and Will Solace to fight with them in the impending war. This should be interesting.
