Captain America was practicing at his base. When he heard on the radio about and attack on the city so he stopped and made his way towards the city.
Once he got there a man with Short brown hair and Brown eyes in black and red armor with a large sword with a black blade and red stripes at his hip kicked him into a car.
"Who are you?" Captain America asked as he raised his shield but he rushed him.
So Captain America tossed his shield but the man swatted it away and tossed him threw a wall then held him off the ground by his neck.
The shield came back but the man caught it and rocked Captain America across the side of the head with it. Then he knocked him out with a boot to the face before leaving with Captain America over his shoulder.
