Agent Spartan (Percy Jackson meets the Avengers)

The war had been won but at a terrible cost, many demigods had died at the hands of Gaia and her army but One that survived was about to be thrown into a whole new world of trouble.

He's saved the world twice but now he must deal with protecting the Lives of half of the universe. Something is coming that even the gods are scared of so they send the greatest warrior to live and help Earths Mightiest Heroes.

Will they trust him?

Will he be able to save everyone again?

Will he be able to forgive himself for the hundred of deaths he has seen?

After all, what hope do the avengers have without him at his full capabilities. He will decide the outcome of this war. He will be the change in the tide. He is Percy Jackson and he is about to get a lot more stressed.
