Daiyōkai

A Daiyōkai is a very powerful type of demon that is much stronger and smarter than the common yokai. Most daiyokai have long life span possibly even longer then a normal yokai's life span. Most are able to remain calm in battle even if the situation is dire or their life threatened. Daiyokai are able to transform into human looking form, an example of this would be the Great Dog Demon and Sesshomaru. Some daiyokai are very large in size such as Ryukotsusei and the Dog General, but not all of them are. Hosenki's true form although larger than the average size of a yokai, but was much smaller than either of them. Some Daiyokai seem to be feudal rulers over vast territories and may command lesser demons. They sometimes wage war against other yokai and humans alike.

Daiyokai who have offspring with humans will produce a half-demon who inheirit their power(Daihanyo). The hanyo are not able to handle the power properly, so when their life is endangered they will transform into berserk yokai that will kill anyone it sees. Inuyasha is an example of this.
