Of particular note, the character in question was presented in her "adult" form long before it was revealed that she was even capable of changing her appearance, and even longer still before it was revealed that her natural age was 12. And even then she wasn't ever really one of the popular girls in the series among fans. That's one of the things that Oda is really great at though: subverting expectations about the characters in a way that is compelling and thought provoking rather than ham-fisted and mean spirited. He's even managed to create several "trans" characters that are actually well liked even by people who generally despise the current year LGBTQ bullshit.
