The trivia section states:
It was confirmed by Morgan Berry, Thirteen's voice actor in the english dub, that Thirteen is indeed androgynous, meaning they use the pronouns they and them. However, their assigned at birth gender is unknown.
How does the claim of the English voice actor confirm the character's pronouns in-series? He is just a voice actor, not the script writer. In the japanese language Thirteen is referred to as a he.
First Morgan Berry is a woman, second she was told by the director that the character is that way and thus to voice the character in that way and third Thirteen is in fact NOT referred to any gender in Japanese. Any scanlation that referes to Thirteen as he or she are incorrect guesses. Even Viz messed that up since they have to make guesses to make sentences flow better (they also referred to Nana as a he for instance in All Might's dialouge with Izuku when he admits he wasn't born with a quirk but his master was so they aren't perfect).

That was still just the director's instruction. Not the actual series creator's confirmation. As for the manga pronouns, I am honestly not quite sure myself anymore. I will try to find the official source.
Agreed, the original manga is the go-to source material.

Why is the article protected? I was about to fix this horrendously missing gender icon, unable to refresh and preview the page.
The article was protected because of repeated edit wars regarding the gender. The gender icon is part of the character template; uploading an image with the proper name and file type will automatically add it. No need to edit the actual article. Dragonus Nesha (talk) 17:05, April 11, 2018 (UTC)
I've read the light novels, Thirteen is referred to as male. As far as I know, they're canon as well. Should we change it based on aforementioned evidence? Rainwingloverforever (talk) 07:39, September 29, 2019 (UTC)

The new official data book confirmed she is a woman. All gender pronouns before were the translator making a "mistake". Japanese doesnt (usually) use gendered pronouns so sometimes a translator has to guess. Thirteen was always referred to in a gender nuetral way before the new data book.
