Honoured with the tragedy of having an arc reactor in her chest, teen genius Macy Moore get thrown in blind to a world she wasn't expecting. When the Avengers are summoned a year after the battle of New York, Stark says he's out of the field but there is always an alternative. Macy. With Loki escaped from Asgard and extraterrestrial attacks happening around the globe, the Avengers Initiative is put back in place. Even though Loki himself hasn't been spotted, it seems clear that it's a work of mischief. A child in a war machine could just change the trickster's ways without trying.
As a world renowned kid genius, she's created and built things ten times better than Iron Man at half the age of Tony. Even though she seems harmless, someone with so much knowledge can be more dangerous than a man of mischief.
After waking up with the arc reactor in her chest, Macy doesn't exactly react kindly to it.
After apprehending Tony from spying in on her lab, Macy rejoins the living for the first time since the explosion.
