That's not true. Ga-Matoran are all female, true. But other than that, to the best of my knowledge, all other blue characters are either genderless or male. Edit: except Kina ofcourse. Where did I say anything about blue characters? Blue has been used for a number of non-water characters. Fair enough. Tarix is from the Water Tribe, Vezok was a Skakdi of water. To name a fiew.
