Dabi was born female, and slowly figured out after waking up from his coma. He wears binders to hide his chest and luckily because of his quirk his voice sounded masculine.
When the League moved into the PLF Villa, he had to deal with the hero Hawks. The guy was insistent that he wanted to help the villains but of course Dabi didn't trust the guy. Him and Hawks then had a one night thing, it wasn't for love only pleasure. He made sure that Hawks wore protection, of course
Then he slowly started to feel wrong. His energy was running out far faster, food tasted weird and he had a few mornings of nausea. He got suspicious that maybe he had gotten pregnant so took a test. Unfortunately his suspicions were correct.
