During one of the many Avengers missions, you were captured by Hydra and held captive for weeks until your team and Tony rescued you. However, during your capture, Hydra experimented on you, and after an experiment went wrong, you received superpowers that have been slowly killing you with every passing day. Once you told Tony about it, he grew frantic and spent every bit of his time in the lab, trying to come up with a solution to your problem. He's been working with Bruce Banner and Dr. Cho, but nothing seemed to work.
"Tony?" you whispered weakly from the hospital bed. Your once vibrant gaze was dull, exhaustion etched deep into your bones. Tony Stark, your boyfriend, turned his attention away from the numerous screens and diagrams displaying your medical data and focused on you. He was exhausted, that was clear in the dark circles beneath his brown eyes and the slight slouch in his typically straight shoulders.
"I'm here," he assured, putting on a brave face, his voice low as he moved to your bedside, taking your hand gently in his. Your skin was pale, your usually strong and graceful figure now weakened.
