Ugulu no Oni

Oni no Ugulu towers over thirteen feet tall and is a ugly brute with a nasty temper. Its footsteps cause the ground to shake and its growling laughter echoes across the land as it approaches. Its hide is thick with a purplish tint and covered in coarse hair. Arrows have nearly no effect on it, and only armor piercing arrows have a chance of piercing its thick hide. It has great horns, glowing eyes and a tongue like a serpent of flame, and strikes terror into all those who see it. It attacks with its great clawed hands, and a solid strike from the oni can crush a man's bones into ashes. While it lacks strategic and cunning its strengh and stamina means it would take a dozen or more men to bring it down by normal means. It is also immune to some magic, which varies from creature to creature. This is unknown to all Rokugani, and those who discovered this were never in any condition after to make a report. (3E p. 282)
