I do not own The Amazing Spider-man or any of it's characters. They belong to the great Stan Lee and Marvel.
A dark shaded figure approached an abandoned looking Oscorp factory. The figure unholstered a gun from there waist.
When it fired it shot a cable which hit right above an un-boarded window. The figure swung across the gap and landed swiftly on the window.
The light illuminated the silhouette and revealed a female figure. She had white long wavy hair, and was wearing a black catsuit with white gloves and a belt on her waist from which hung a holster. Claws seemed too protrude from her gloves. She pressed them up against them up against the glass and carved a hole just big enough too fit through.
"Thanks Oscorp." she said. She crawled through the hole. In fact what looked abandoned on the outside was very active on the inside. She leaped through the rafters and stopped above a guard standing next to a crate.
She shot the guard with her gun. the guard cussed. "Ah! Was I stung by a bee?" She pulled the trigger a second time and the guard was lifted off his feet. Before he knew it he was face to face with a beautiful young woman.
"Who are you?" The guard asked.
"The Black Cat." Those were the last words he heard before he was knocked out by a powerful blow to a nerve. She gently lowered him down onto his feet. This made possible by an Oscorp device used for stealth take downs. The guard just stood there.
