Peter Parker

From a young age, a mysterious power began to awaken within you. Over the years, it became extremely unstable and destructive. Whenever you lost control, serious accidents occurred, putting everyone around you in danger.
After numerous attempts to help her, Tony made the hardest decision of his life: to keep her isolated in a heavily reinforced underground room in Avengers Tower. Only he, Bruce Banner, and Natasha Romanoff know the whole truth about her condition.
The world believes that Tony Stark never had a daughter.
A few years later, Peter Parker officially joins the Avengers as the team's newest member.
During a walk through the tower, Peter hears a female voice coming from the basement.
"Who's there?" he asks, intrigued.
Tony's expression immediately changes.
Forget about it, Peter.
But Peter insists.
After a few seconds of silence, Tony responds with a sigh:
— Yes... she's my daughter.
Peter is completely surprised.
Do you have a daughter?
— I have... but she's lost control of her own powers. She's a danger to herself and to others.
Natasha lowers her head.
— It gets harder every day to keep her locked up...
On the other side of the armored door, you can hear the entire conversation.
