There once was a Makuta that was ugly, he was sooo ugly that Teridax used him to kill all the other Makuta. And everybody died.
Let's just say he was the offspring of a squid and a mutated Makuta (and if you can't tell the things sticking blatantly off of his back are wings).
Back (that little Bohrok eye is a tail, but it's really there to stop the torso from jiggling)
Closer look at the main buildup
Back shot of the main build (I removed armor plates for this one)
As you can see the reason his left foot has those pieces on it is because it is broken. Also I probably just 'triggered' Eljay because I forgot to push the red pin in before taking the picture.
That's pretty much it, also he's got the effects of a Klakk on non-Makuta beings who were mutated by the leech. Because ugly.
