Umrach
this unusual creature was bioengineered by the Yuuzhan Vong, and set loose in the underworld of Coruscant, shortly after the alien invaders took control of the planet. Half reptile, half mollusk, the umrach stood on two stout legs. Its arms were insectile tentacles, and its head was a mass of waving tentacles. The mouth of the umrach was filled with spear-like teeth, which it used to impale it prey. For its large size, the umrach was surprisingly fast, and could catch a running person in no time. These creatures were designed to help eliminate any survivors from the Battle of Coruscant, so that the Yuuzhan Vong could transform Coruscant into a simulacrum of their long-lost homeworld, Yuuzhan'tar.
