I think that lovely little splash of Metru Red was exactly what was needed here.
Not that it really needed much. I mean, man, that build is impressive. Big impressive. Complex impressive, but not too cluttered or anything. I like that.
And that head! Mask? Either way, it has a very intimidating look about it. I wager it's the teeth but those long long spikes might have something to do with it too.
And he's wearing the Mask of Control. As a necklace.
Or at least just around his neck.
If any a form G2KA (G2 + Makuta = G-2-TA lol ) were to take on, I'd say this would be one of the fiercest. Best of luck to you!
