Thunder Brothers

The, also know as the Thunder Beast Brothers, are two demon brothers, named Hiten and Manten. They and their sister Sōten are the last surviving members of the Thunder Demon Tribe. However, the Thunder Brothers are much stronger than their little sister, who instead has developed her tactical genius to compensate for her small stature and lack of raw power. The Thunder Brothers often kidnap attractive women, both human and demon, and use them for food and sex respectively. They killed Shippō's father to get a piece of the shikon jewel. Manten made himself a sash with Shippo's father's hide (a belt to remember killing the father). Shippo tries to get revenge on them by stealing part of the Shikon no Tama from Inuyasha and Kagome, but soon works with them to kill the Thunder Brothers (though Inuyasha did most of the fighting).
 * Hiten is the older brother from the Thunder Brothers and more human looking of the two. He has a weapon that can control thunder which is why they are called the Thunder Brothers. He had a girl demon with him in his first apperance but killed her after becoming angry at Manten for letting a piece of the jewel get away. He is the one that battles Inuyasha.
 * Manten is the younger brother, who can blow fire from his mouth. He does not have but a few strands of hair so he tries to keep all of them, but soon becomes bald because Kagome shot an arrow at his nose and two of the three were shaved off and the last one came off because of Shippo's fox magic top illusion while Shippo was trying to save Kagome. Because of this he tries very hard to kill Shippo and Kagome. He dies even so, and Hiten bites him; his head on his jewel shards in the anime and his heart in the manga; so that Manten's body can be inside Hiten, so that Hiten will always have his brother beside him. He mostly fights Kagome and Shippo.
