Kinetic (Bucky Barnes)

Seraphina "Sera" Rogers, Steve Rogers' long-lost sister, was discovered during the Fall of HYDRA and SHIELD. But she wasn't there as his sister, she was there as his attacker. In her eyes then, he was her mission, along with the Winter Soldier. Neither of them remembered him. Neither of them remembered themselves.

But time, healing, and fragments of the past have a way of resurfacing.

In the years following the Blip, Sera began to recover memories, her life before HYDRA, her brother, and perhaps most painfully, her love for Bucky Barnes, feelings that never died, only buried deep beneath years of torture and programming. Unable to face them, and afraid of what they meant, Sera vanished without a trace.

Now, in 2027, she works under Valentina Allegra De Fontaine, dangerous, loyal only to herself, and assigned one final mission. But when she's forced to join the very man she's been running from, old wounds reopen, old feelings ignite, and the line between weapon and woman begins to blur.

Because Sera Rogers was never just Steve's sister. She was the girl who loved Bucky before the war. And maybe, just maybe, they can get the redemption neither of them believes they deserve.
