Cactus Demon
A Cactus Demon, being a humanoid covered in bandages with sharp spikes sticking out, was one of the more proactive lost souls lost in a dense universe to which Shiva sent Jenny Everywhere and David — allegedly as punishment, but actually in the hope that he would inspire the lost souls to rise up and save themselves from the decaying universe.
As all the wretched souls could comprehend was pain, they tried to torture their two human visitors, with the Cactus Demon using its spines to hurt David. However, both managed to achieve a zen mind-state which allowed them to harness the powers awarded to them by being from a lighter universe. After they succeeded in evacuating the decaying underworld's population, Shiva began tending to the lost souls, unraveling the Cactus Demon's bandages to tend to the burnt flesh beneath.
