Tony was born a Vampire. He doesn't know what his wings look like. A corrupted soul cannot see their wings.
He used to wonder what they would look like when he was young. Over time he had learnt not to think about it. It didn't really matter. He controlled his own future, his own destiny. He didn't need a soulmate to find love and happiness. He was above that.
Or so he thought until he met Steve Rogers.
One day in the lab he caught himself thinking about Steve's wings and if they matched his own. He snapped himself out of that thought immediately. It wouldn't do to think about such childish dreams, not when there's so many more important things for him to be thinking about, to be doing.
Steve Rogers wasn't his soulmate. He didn't need a soulmate.
What he needed was to pull his head out of the clouds and start focusing on his work.
But why did that feel so hard?
The last time he saw his wings was right before he was given the serum. Before he was turned, infected.
He remembers them. Sickly, pale and small, always losing feathers. But they were a soft gold, like the first rays of sun in the morning.
They hadn't finished developing before he signed up for project rebirth. He sometimes liked to imagine what they would have become. If they had kept the same warm colour. Or if it had changed. If they were more vibrant now. If they were more like a sunset, like Tony's, a gentle fire slowly burning.
But it did not matter how many times he tried to sketch it, he could never quite get them down on paper. It always felt uncomfortable to draw himself now. Like his brain hasn't caught up to the serum's changes yet. Any wings he drew always felt too big, too large for the smaller frame he was used to.
After a while, he stopped trying.
He just had to hope that his soulmate, if they ever meet, would recognise his wings.
