>>8468158"Humanoid" in fantasy/sci-fi just means "two legs, two arms and a head", though. You can still get creative with that. A Toa is a humanoid, but so are a Rahkshi, a Skakdi, Takadox, Chirox or arguably even Krika.
The Marendar contest is still going to be interesting, since other than "humanoid" and "slightly taller than a Toa" we have no info about him/it/they/zim/zoom.
Not even his colors. I recall Greg mentioning that his inspiration were the Sentinels from X-men, so maybe it would be philologically accurate to make him blue and purple? Not that the man would care since he "thinks in words" or something. But, I'm still throwing that out there.
