The Costco sat dark and lonely. Long abandoned, it was dimly lit but fully stocked. Carts littered the store, left behind by people now long gone. Steve stepped inside the Costco. He didn't know where the little English woman he'd been following had gone, but he'd find her. He heard a small sound coming from his left, in the next aisle. To a normal human ear it would have been almost imperceptible, Steve Rogers was anything but an ordinary man. He advanced slowly, cautiously on the aisle. His senses honed by years of combat straining for any sound that would give away his opponent. Tracer breathed heavily in the near darkness of the store. She strained to see in the dark, struggled to hear over her pounding heartbeat. She worshipped heroes, and in any other time the man following her would have been someone she'd ask for an autograph. Now, he was her enemy and as much as it pained her to do it. She'd have to take him out. Her focus snapped back to the present as she heard a piece of glass crunch under a heavy boot. Tracer blinked forward to the end of the aisle and towards the shadowy figure that has rounded the corner. She reappeared behind the blue clad figure and leveled her pulse pistols. "Cheers luv" was all she managed to get out as the man spun impossibly fast. His big shield knocking her pistols aside. Maybe next time no quipping she thought to herself as she blinked backwards, dodging the followup punch he threw. Cap cursed as the lady teleported out of close quarters. His keen tactical eye noticed the device on her chest faintly glowing as she used her powers. That must be the source of her abilities he thought to himself. He charged forward his his shield held out in front him going back on the offensive. He felt the vibrations as the shield absorbed fire from the Brits sidearms, then a meaty crunch as he connected with her nose. Blood spurted from the girls now broken face, "damn that hurt" she cried. She flickered momentarily before disappearing in a blue light. He spun around just in time to catch the knee to the chest from the girl who was suddenly behind him. Oddly enough her nose was now completely fine. She's ethier a healer like Logan or she heals when she bamfs he thought. He grimaced as the knee hit him in the chest. It didn't really hurt more then any other normal person kicking a super human in the chest though. He lashed out with a gloved fist right into the apparatus on her chest. "Bollocks" the girl cried out as the device started to flicker and spark. With a look of panick creasing her fine face she tossed what looked like a bomb at Steve. As it clung to his shield he heard the rapid beeping of a countdown. Tracer felt a sudden calmness as her pulse bomb adhered itself onto the American idiots frisbee. Her calmness quickly turned into dread as that damn frisbee came sailing back at her, with her pulse bomb still attached. The explosion threw Traver backwards. She felt the heat of the explosion scorch her arms and face. Her eye shredded as one side of her goggles cracked and burst inwards. Her pulse pistols went flying out of her hands, plucked away on invisible strings. The tile floor felt hard as stone as her head bounced off it with a loud crack. As she slid with a crash into a shelf she stared at the approaching man with one half open eye. As the man raised his shield up above her she only hoped someone would clean out her Gibraltar locker for her.

Sorry that was long and poorly written. It's late and I'm not a writer. So I give it to cap because Tracers a trained member of Overwatch but she's up against Captain America. He's not invincible but he's got the quick tactical mind that let him figure out Tracers weakness and he just outpowers her. Simply put, they're not on the same level. Everything she has he's already seen. He's fought better shots, better fighters and quicker people.
