I have some very important and factual information that the BNHA community needs to know about Dabi. This will be a thread, because it contains an absolute crucial plot point that may or may not affect the plot later on as the story progresses. With that being said, let’s begin:

1. Dabi, or Touya, rather was assigned male at birth, which is a given fact since Enji, Rei, and everyone else in the todoroki family referred to him as their first born son, eldest brother, etc. since Touya was born. Throughout the story, Touya and Dabi consistently use-

He/Him pronouns. Which solidifies the fact that Dabi is a cisgender male character.
2. With this knowledge, we put together the fact that Dabi, canonically, has a penis. A dick and balls. That has the capability to become erect and ejaculate semen. -

3. Just about all AMAB people wake up with morning wood, and with the assumption that Dabi doesn’t have any erectile issues, we can infer with context clues and solidify the fact that Dabi has canonically, at some point in the story, has woken up with a raging boner.

4. Based on the way that AMABs go through puberty, we know that they often get spontaneous erections and orgasms. Which we can come to the conclusion that Dabi canonically has came at least once in his lifetime.

5. We haven’t seen any clues or hints that there is any form of organized religion in the BNHA universe. Which means that there aren’t any religious laws that would require circumcision.

So with all these key facts paired with critical thinking and logic, we have come to the conclusion that Dabi canonically has an uncut cock that be sploogin.
