The Catalyst//Bucky Barnes

She had two options: save who she used to be or save the man she loved.

Delilah has loved Bucky Barnes for as long as she can remember. When he left for the war, she refused to wait on the sidelines and enlisted too. They fought side by side until an accident tore them apart-sending Bucky off a mountain and Delilah seventy years into the future.

Now, Delilah is a woman out of time, haunted by the loss of the man she loved and grappling with powers she doesn't fully understand. Her life takes a sharp turn when she locks eyes with a ghost from her past: Bucky. Only, he's not the man she remembers. He's the Winter Soldier-the most deadly assassin with no memory of her or himself.

As Delilah fights to bring Bucky back from the brink of destruction, she's forced to confront her own identity. The powers she's always feared may hold the key to not only saving him but to discovering her own strength-and realizing she's always been more than what she can do.

In The Catalyst, love and identity collide as Delilah faces her greatest battle yet: choosing to embrace who she is and fighting to save the man she refuses to give up on.

Delilah is NOT replacing Steve/Captain America!!!! Think of this as a What If...Steve Rogers had a sister?

All credits to Marvel, I only own Delilah and a few small characters and a small portion of the plot.

This story takes place from The First Avenger into The Winter Soldier into Civil War.
