I can't believe the best picture of this I have is from a 'draw your character in your clothes' meme

Pointed piggish ears

Claws on both hands and feet

Two bumpy horns on his nose

Serpentinite spikes and brown Tennessee marble cabochons on his shoulders, back and elbows
         As a nod to his Fourth alignment, the white veins in the Serpentinite form circuitry patterns.

The ability to grow in size, up to 20 feet, one hour per day.

Affinity for mimicry and ability to take on a magical disguise, one hour per day.

Berserker state.

Weakness to sunlight.

Hunger for human flesh

A short temper and tendency to get defensive

Two sharp tusks

A long mane extending down his neck and back

A long tail with a furred tip

A single heat-sensing eyeball in the middle of his forehead

Slightly out-of-proportion arms, hands and feet for that brutish look
