There'a a character named Vivian in Paper Mario: The Thousand-Year Door who we only know is trans because one of her sisters constantly misgenders her. Her character arc includes her standing up to her sisters and learning to respect herself while travelling with Mario. In the English localisation they made her sister mean and removed the transphobia, thereby also removing all references to her gender identity. There is a remake releasing soon, if the transphobia is back that means that they’ve decided to put the trans rep (that was once absent from the english release) back in.
