Ah, you don't know. Malphite is a champion from League of Legends. Your rock monster looks kinda like him, hence my comment. ^^"
Well, okay, but there are lots of rock golems...? League of Legends isn't the first or only game to have a creature along those lines. My client specifically asked for this type of creature design, and I highly doubt they had LoL in mind either.
I know. It's just what came to my mind when I saw it first.
