Kibito is the right hand man of Supreme Kai. He was killed by Dabura, but brought back by the dragonballs. He later fused with the Supreme Kai, becoming Kabito Kai.
Kibito is a tall, blue-skinned Shinjin (red-skinned in the anime). He possesses white, long hair and a broad face. He wears the attire that of the Supreme Kais.
Kibito remains quite faithful to Shin. Kibito is a kind-hearted guy but was originally disdainful of Gohan and does not like the idea of mortals stepping foot on the sacred world of the Kais, partially because he was jealous of the Saiyan's strength. In the manga of Dragon Ball Super, it was noted by Shin that Kibito has some distrust in mortals, not trusting them to handle matters of great importance. Despite this, he remains true to his duties and is willing to admit when proven wrong about an individual's abilities. It is said that he studies a great amount about Universe 7, yet he isn't informed about all the races in Universe 7, as he did not know about the Metalmen in his universe.
Statements by authors and guidebooks
It is never made clear in the manga or the anime how powerful Kibito really is, but his profile in Daizenshuu 7 states that his power level is considerably high, enough to give Gohan a difficult fight as long as he was not a Super Saiyan. He does however show that he lacks the strength that Gohan has in his normal state, unable to budge the Z Sword that Gohan was able to lift up and swing. In the Dragon Ball Super manga he spars with Zamasu. He holds his own for a while, but ultimately proves to be no match for the fighting prodigy.
