Moving on to 3rd edition OA there are a few new monsters in this book that were not in 1e. Converting them here.
Onikage, or demon horse, are mounts used by oni and their servants to travel between Spirit Realms and for cavalry. These horses are demonic undead creatures with scaled, horse-shaped bodies, long fangs, crocodilian tails, glowing eye sockets, and clawed hooves. They range from dark green to bruise-purple, with tentaclelike manes of contrasting color.
Onikages hunger for living flesh, and if they are alone they attack any living creature without thought or fear. These foul creatures often serve as mounts for still worse oni allies, however, and learn to bring their instinctive hunger under control when they carry a rider. Onikage are most often found serving as mounts for maho-bujins, akutsukai, or akutenshi.
