Inspiration/Summary
So, instead of Percy getting kidnapped by the Avengers, I thought about, well, what if the Avengers were unknowing parts of the pantheons? Basically what happens after the war with Gaea (Trials of Apollo never happened) and everything has settled down. Or has it? (Thanos will be coming, probably)

Important to Know
1) Not all the heroes are going to be children of the gods, some may be legacies
2) Asgardians (Thor), will remain as themselves, but can still have kids.

The People

Steve Rogers, Son of Arete (looki it up)
Tony Stark, blessed by Athena, Legacy of Hephaestus (Great-Grandfather)
Bruce Banner, Son of Athena
Black Widow, Ex-Hunter of Artemis
Thor Is Thor
Clint Barton, Legacy of Apollo
Bucky Barnes, Son of Adrestia (look it up)
Spiderman, son of Athena
Deadpool, son of Nemesis, legacy of Janus
Scarlet Witch, (a) champion of Hecate
Quicksilver, blessed by Hermes
Scott Lang, Son of Hermes
Black Panther, Champion of Bast

These are the first of whom will appear.

Basically, its the Avengers learning their heritage (some already know it though)

I found Spiderman's part on Pinterest, no idea who original author is. (You'll find it if your search 'spiderman son of athena')
