Tidal Wave (HoO AND AVENGERS CROSSOVER)

Percy goes to live with the Avengers. The Avengers then realize something strange about the boy. There is an emptiness in his eyes and the way he and his girlfriend, Annabeth, are so protective over each other. What's his deal?

The Avengers are going to lose against Thanos, luckily they made a new powerful friend and he has powerful friends of his own.

Takes place after Blood of Olympus. In the Marvel timeline it's kinda messed up because the storyline changes completely, I guess it's around about the time of Infinity War.

*Disclaimer: I don't own Avengers (that's marvel studios) or anything PJO or HoO related (they go to good old Uncle Rick). I made the cover picture but it's obviously Viria's art and a pic from in Infinity war that I just put in the same pic.*
