Really? Where is that from? On the topic, I noticed that while the Matoran of Voya Nui were suspicious from the start of the Piraka's appearances, actions and motives, they never questioned Vezok being a male "Toa" of water, implying that Matoran who identify as the opposite gender from the norm for their element are generally known and accepted, at least on Voya Nui. I always thought that Vezok was pretending to be female... I don't think so. When Dalu was talking to him in the book "Island of Doom" it clearly stated that she knew he was a "he" At least, the narrator of the book mentioned him as a he, and that her thoughts registered him as a "he".
