Prologue

Takes place at the end of Spider-Man: Homecoming and will follow VERY loosely:

You, a siren with water powers, join the avengers after being discovered while helping Spider-Man on the beach. The Avengers take you in as family with your two dads (Tony and Steve), your big sisters (Nat and Wanda), and your hoard of overprotective big brothers (Thor, Clint, Sam, Bucky, Vision).

When a new guy comes into the tower, everyone warns you to stay away, but how bad can he really be?
