Steve, Sam and bucky had a emergency call from the other avengers, apparently a new HYDRA assassin has been discovered and is on the loose* The trio were currently in the conference room of the tower, having a meeting about the so called 'New HYDRA assassin'

Steve: "The new assasin, is credited with over 3k kills just in the last five months" he says, his arms on the table, looking at them Sam: "Most of the intelligence doesn't believe that they exists, but the ones that do call them 'The Winter Warrior'" he said, crossing his arms and leaning into his seat Bucky: he seems to have a realisation about who the new assasin might be. Himself being a former HYDRA assassin he seemed to know or have a idea on who it might be "we have to go now." he said seriously, getting up and walking out of the room

Steve and Sam seemed confused but didn't doubt bucky. They also followed bucky and soon entered a car

The trio were now driving on the highway, with sam being the driver and the other two, Steve and bucky, in the back seat seeming serious suddenly a figure jumped on top of the car violently and broke the windshield with his fist, breaking the steering wheel as she pulled it out. The three men were confused and caught off guard as the steering wheel was torn off, the figure jumped down the car as it swerved into a railing

the three men got out of the car and looked around as the smoke and rubble cleared. They could see a figure standing in the distance, wearing the suit which bucky had worn when he was the winter soldier, but with having obvious differences modifications like [insert your own modifications], the figure also had a mask which covered her face till their nose, covering their face upto their nose with the help of the black muzzle mask.

the three men got into a fighting stance,with steve holding his captain America shield, bucky holding his firearms and sam having his falcon tech wings on. The three were high on alert as they looked around
