Many Tries Later (aka. Fixing Infinity War)

Emmaline Julia Hill, or so what she told them, was a complicated girl. She showed up on Earth with a ragtag group of space adventurers and Thor along with many Asgardians and also Bruce Banner in tow. Not long after another group came from space claiming to be "Children of Thanos" and Emmaline sent those that tried to ask her to Gamora, saying she can explain. The Children of Thanos come and they fight Earth's Mightiest heroes and discover that Emmaline has remarkable powers... and that she is one of the main targets of Thanos and his "children." After the fight, they lock her up to question her and find that there is much more to the blue-haired wannabe-anti-hero than they originally thought and learn what was truly at stake during that battle.

(I'm going to be honest, this is a bit OC-centric, this is all me putting one of my OCs in the Marvel universe and just letting her do what I think she'd do. Tell me what you think and give suggestions, this is my first fanfic after all!) -Luci
