Ohme (オーム) is the fourth boss from Ghouls 'n Ghosts, a gigantic worm-like monster that acts as the guardian of the demon gate in an underground lake that leads to the castle. The beast is immobile, but it has its offsprings do its work for it. Smaller maggots emerge out of its five exposed hearts, and long red worms crawl their way from underneath its skin. The only way it can be killed is if Arthur throws his weapons downward into its hearts, all the while avoiding the smaller creatures slithering around.
