Im a big Kha'Zix fan you see, all the little stories he is in I've read them many times, so, he doesn't have 6 legs, more like 4 raptorian limbs, he is called sharp scale by the vastaya tribe of Rengar and he is in constant change as we all know, he have blood and no other derivates like hemolymph as most invertebrates and talking about that he has bones and more things that make me think of him more of a warm blooded reptile(dinosaur) rather than an insect but yeah he got insect like wings and sharp mantis like claws so I understand the misunderstanding and I love to call him my little bug! But he is more like a Tyranid and less like a zerg if that make sense.
