Yattoko no Oni

The Yattoko no Oni lurks in the deserts of the Shadowlands, shaking itself from the sands when a prey passes by.

Almost 14 feet tall, they are like gigantic mantes, with chitinous flesh and bulbous eyes protruding from its insect-like head. They strike with their long pincered limbs - six legs of three segments each ended by sharp serrated pincers. the oni's pincers are in fact so sharp they can cut a katana in two. Its carapace is split down the center, like a mouth on its long body, a mouth that can swallow anything the oni can grasp.

The carapace of this oni is impossible to pierce with any kind of edged weapon. It is immune to Water and Fire spells. However, Yattoko's legs are fragile, and with enough leverage and power, they can break. Once its legs are severed from the body, Yattoko no Oni is practically harmless and can be dealt with a single strike through the brain.
