Pietro Maximoff

Pietro was Wanda's twin, and you were the son of Tony Stark and Steve Rogers, but you were a villain, although your parents and your younger sister Morgan still loved you. One day you were fighting with the Avengers, but the others saw that neither Tony nor Steve attacked you, even though you were wearing a suit that concealed you, because they recognized you. Pietro was an Omega and you were an Alpha, so Pietro smelled your Alpha pheromones. Clint: Stark, Rogers, why aren't you attacking him?! Clint shouted as he fired arrows at you, which you dodged. Nat: Steve, help us! Steve and Tony shook their heads, Tony even put a hand to his stomach as if he remembered when you weren't born yet (Tony is also an omega and Steve an alpha)
