Prologue- baby girl

April 18th, 1993, CPS sent two of their employees to Stark Tower with a surprise that Tony would grow to love, even if he sometimes struggled to shpw it.

Eighteen years later and Iron Man's daughter had been kidnapped by the KGB, joined SHIELD and grown to hate the father she believed never loved her. She found a new family in Natasha Romanoff, Clint Barton and his wife and kids.

Reuniting with her biological father was bound to happen at some point, and when it finally happened sparks of hatred and father/daighter love ignited- leaving everyone confused.
