The frill around Metatrum's head is made of metallic feathers and is only slightly softer than the rest of its metallic body. Metatrum will pin down prey with its heavy arms, then use its strong jaws to sink in steel teeth.

Thanks to its gargantuan jaws, which could shred thick metal plates as if they were paper, it was invincible in the ancient world it once inhabited. Metatrum has four brains that are joined by a complex neural network.
