( i know this might sound stupid) But i was really bored so i had a look at a database and i saw the Gaia Crown the only thing that bothered me was that Gaia is a Greek goddess (or roman if you changed the name to Terra) is it meant to be like a godly hat??
This belongs to general, but whatever.
Gaia, as far as I remember, means "Earth". It's a hat specialboy(?) won in a chaos tournament. The name clearly suggests what the hat is.
Sorry, but common sense denies your whole topic a little bit =/
Well if you knew what Gaia was the goddess of, that would've answered your question for you... -earth goddess-
The hat is a bunch or rocks on his head (despite people saying it looks like a pile of nachos).
Gaia->earth->rocks. ta da.
